Question 1

How do I choose a fire extinguisher? Which type should I have at home?

Accepted Answer

Start by identifying the type of fire you need to protect against. Household fires most often involve cooking oil, electrical appliances, paper, and wood, so a water-based fire extinguisher is recommended: it cools effectively, leaves no powder residue, and has a low reignition rate. Zhongjiawoan's room-temperature portable water-based fire extinguishers come in 2L, 3L, and 6L sizes, and it is sensible to keep one in both the kitchen and the living room. If you are concerned about combined electrical and oil fires, you can also add a portable dry powder fire extinguisher. When purchasing, look for the CCCF mandatory product certification mark, and determine the quantity and placement based on your home's area and layout.

Question 2

Are Zhongjia Wo'an's fire extinguishers CCCF-certified? How can I verify their authenticity?

Accepted Answer

Yes. Fire protection products from Zhongjia Wo'an, including water-based and dry-powder fire extinguishers, have all passed CCCF mandatory product certification (China's market-access certification for fire protection products) in accordance with national requirements. You can verify a product online at the official website of the Fire Product Conformity Assessment Center under the Ministry of Emergency Management (www.cccf.net.cn) by entering the product certificate number or model number, and check whether the manufacturer, product name, and model specifications match. When purchasing, you may also ask us to provide scanned copies of the certification and inspection report for verification, ensuring you receive compliant, genuine products.

Question 3

Where and at what height should a household portable fire extinguisher be installed?

Accepted Answer

We recommend placing a portable fire extinguisher in an easily accessible spot that does not block your escape route, such as the kitchen or near the entrance, while avoiding direct sunlight and hot, humid conditions. Per the national standard (GB), the top of a portable fire extinguisher should sit no higher than 1.5 meters above the floor, and its base no lower than 0.08 meters, allowing adults to grab it quickly. Zhongjia Woan's 2L/3L/6L ambient-temperature water-based extinguishers can be wall-mounted or placed on a dedicated bracket. Never tuck it deep inside a cabinet or bury it under clutter; make sure it is within arm's reach in an emergency.

Question 4

What is the service life of a portable dry powder fire extinguisher, and how should I handle one that has reached the end of its service life?

Accepted Answer

Under China's national standards, portable dry powder fire extinguishers generally have a service life of 10 years from the date of manufacture; however, a hydrostatic test in accordance with GB requirements is required every 5 years and before each recharge, while wheeled (trolley-type) extinguishers must be retired after 8 years. Service life is determined primarily by the manufacture date on the nameplate and the cylinder inspection markings. Do not dispose of an expired extinguisher yourself; it should be turned over to a qualified maintenance provider for retirement and recycling. Never discard it carelessly or strike the cylinder. Zhongjia Wo'an offers annual inspection, recharging, and end-of-life recycling consultation services, and our customer service team can help connect you with a compliant local maintenance provider.

Question 5

What's the difference between water-based and dry powder fire extinguishers, and how do I choose?

Accepted Answer

Water-based fire extinguishers use water plus additives as the extinguishing agent; they cool and lower the temperature on discharge, prevent reignition, leave no powder residue, and are easy to clean up, making them ideal for homes, offices, and areas near precision instruments. Zhongjiawoan's room-temperature water-based extinguishers range from 2L up to a 25L cart-mounted model. Dry powder fire extinguishers work by cutting off oxygen; they are inexpensive and broadly applicable, but they produce heavy powder residue and can corrode electronic equipment, so they are better suited to garages, factories, and similar settings. For home use and environments with electronics, choose water-based first; for cost-sensitive or rugged outdoor scenarios, dry powder is a good option.

Question 6

What is CCCF certification? Which fire protection products must obtain it?

Accepted Answer

CCCF stands for China's mandatory certification for fire protection products. It is a market-access system implemented by the Ministry of Emergency Management for fire protection products that affect personal and property safety; products may not be sold or used without certification. Fire extinguishers, fire alarms (smoke detectors and combustible gas detectors), fire escape self-rescue respirators, and fire blankets fall within the scope of mandatory certification or market access. Zhongjia Wo'an's portable water-based and dry-powder fire extinguishers, smoke alarms, carbon monoxide alarms, and filter-type and chemical-oxygen self-rescue respirators have all completed the applicable certification or type testing as required.

Question 7

What are the correct steps for using a water-based fire extinguisher?

Accepted Answer

Remember the four-step P.A.S.S. sequence: Pull, Aim, Squeeze, Sweep. First lift the extinguisher and pull out the safety pin. Standing upwind, aim at the base of the flames from about 2 to 3 meters away, and firmly squeeze the handle to discharge. When using Zhongjia Woan's portable water-based extinguisher, sweep from side to side to cover the burning surface until the flames are fully extinguished. Water-based extinguishers leave minimal residue and are easy to clean up, making them well suited to home grease-pan fires and incipient electrical fires (cut the power first). After the fire is out, watch for reignition and only evacuate once you have confirmed the area is safe.

Question 8

How long is the warranty on Zhongjia Wo'an fire extinguishers and fire blankets, and what does the warranty cover?

Accepted Answer

Zhongjia Wo'an's warranty policy for fire safety products is governed by the warranty card included with the shipment and the sales contract. Under normal use conditions, extinguisher cylinders are generally covered by warranty; during the warranty period, non-user-caused defects such as cylinder leakage or valve failure resulting from material or workmanship issues are eligible for free repair or replacement. The warranty does not cover situations such as physical impact, failure to complete required annual inspections, unauthorized modification, or normal wear and consumption (e.g., expiration of the extinguishing agent). Fire blankets made of silicone, basalt, or high-silica fibers, as well as automotive fire blankets, also carry corresponding warranties. For specifics, please refer to the product warranty card or contact customer service.

Question 9

What is a fire blanket for, and do I really need one at home?

Accepted Answer

A fire blanket smothers a fire by covering it and cutting off the air supply. It is especially effective for extinguishing kitchen cooking-oil fires and small appliance fires, and it can also be draped over the body for protection during escape. It requires no maintenance, cannot be accidentally discharged, and is simple to use, so even elderly people and children can handle it, making it an essential item for the home and especially the kitchen. Zhongjiawoan offers boxed fire blankets in a variety of materials, including silicone, basalt, high-silica, and fine-spun fiberglass. Simply hang one on the kitchen wall for everyday readiness; we recommend pairing it with a water-based fire extinguisher so you can handle small fires in their early stages with confidence.

Question 10

Are CCCF certification and 3C certification the same thing? Which one should I look for on fire protection products?

Accepted Answer

No, they are not the same. 3C (CCC) is the general mandatory product certification system, covering a broad range of categories such as electrical appliances and toys. CCCF is a market-access certification specifically for fire protection products, administered by the Fire Product Conformity Assessment Center under the Ministry of Emergency Management. For fire protection products, the CCCF certificate is the key thing to verify. For Zhongjia Wo'an's fire protection products, such as fire extinguishers, alarms, and respirators, CCCF certification is the governing standard; certain products containing electronic components will also comply with the applicable national standards where electrical safety is involved.

Question 11

How should a fire blanket be installed and stored, and how do you use it?

Accepted Answer

We recommend hanging the fire blanket on the wall near the kitchen stove, but keep it a safe distance from any heat source so it is easy to grab. To use it, grip the two pull tabs at the bottom with both hands and quickly pull it out, wrap the blanket's edge over your hands to protect the backs of them, then push it forward from in front of you toward the fire, fully covering the pot or burning object to smother the flames by cutting off oxygen; let it cool before removing it. Zhongjia Woan's boxed silicone, basalt, and high-silica fire blankets are reusable. For a grease-pan fire, reach for a fire blanket first, as it is safer and more effective than water.

Question 12

Do water-based extinguishers and CO₂ extinguishers have the same service life as dry powder ones?

Accepted Answer

Different types of fire extinguishers have different retirement periods. Under China's national standards: dry powder extinguishers (including portable models) must be retired 10 years after manufacture; water-based extinguishers generally last 6 years; carbon dioxide (CO₂) and clean-agent extinguishers last 12 years; and wheeled (trolley-type) extinguishers are typically 8 years. Zhongjia Wo'an's ambient-temperature portable water-based extinguishers (2L/3L/6L), 25L wheeled units, and stainless-steel water-based extinguishers must all follow the retirement period for their respective category. Routine maintenance is also required in accordance with the standards, including an annual pressure check and a hydrostatic test every 5 years. Any unit that has exceeded its service life or shows serious cylinder corrosion should be promptly retired and replaced.

Question 13

What's the best way to use a fire blanket and a fire extinguisher together?

Accepted Answer

The two serve different roles and complement each other. A fire blanket is ideal for small, early-stage fires such as those in a cooking pot or a trash can: it responds quickly, causes no contamination, and can bring the fire under control the moment you cover it. A fire extinguisher is better suited to spraying out a fire when the flames are somewhat larger or spreading. We recommend hanging a fire blanket in the kitchen while also keeping a water-based fire extinguisher in the kitchen or living room, forming a two-tier defense of cover first, then spray. A Zhongjiawoan fire blanket paired with a room-temperature water-based fire extinguisher is a common household combination that balances convenience with firefighting capability.

Question 14

How many years is a fire extinguisher valid? Must it be scrapped once it expires?

Accepted Answer

Fire extinguishers have clearly defined service-life limits: portable and wheeled dry-powder extinguishers must be scrapped 10 years after their date of manufacture (with the first maintenance inspection at 5 years), water-based extinguishers must be scrapped after 6 years, carbon dioxide extinguishers after 12 years, and simple (disposable) extinguishers must be scrapped outright 3 years after manufacture. Any extinguisher that has expired, whose pressure gauge needle has entered the red zone, or whose cylinder is corroded or deformed must be taken out of service and scrapped. Zhongjia Wo'an recommends regular inspection and maintenance in accordance with national standard GB 50444, and all of our product cylinders are marked with the date of manufacture for easy management.

Question 15

How long does a dry-powder fire extinguisher stay valid, and how do you inspect it routinely?

Accepted Answer

A portable dry-powder extinguisher generally reaches end of service life 5 years after manufacture, and a wheeled unit 8 years; water-based extinguishers last about 6 years and CO2 extinguishers about 12 years, with the marking on the cylinder taking precedence. On a monthly basis, check that the pressure gauge needle sits in the green zone: the red zone indicates low pressure and the need for a recharge, while the yellow zone indicates overpressure. Also inspect the cylinder for corrosion or deformation, check whether the nozzle hose has aged or cracked, and confirm the lead seal is intact. Zhongjia Woan recommends a full household inspection every six months, and any expired extinguisher must be replaced.

Question 16

Do fire extinguishers need annual inspection and recharging every year, and where should I send them for inspection?

Accepted Answer

Fire extinguishers require regular inspection: check monthly whether the pressure gauge needle is in the green zone and whether the cylinder shows any corrosion or deformation. Dry powder, water-based, and similar extinguishers must be sent to a maintenance provider holding the relevant CCCF qualifications for inspection and recharging once they reach a certain age after manufacture (typically the first inspection at 3 years for dry powder and water-based units, and annually thereafter) or after each discharge. Zhongjia Wo'an advises against disassembling and recharging units yourself, as doing so may compromise safety and void the warranty. Contact our customer service team, and we can help connect you with a compliant annual-inspection and recharging outlet in your area.

Question 17

What's the difference between the silicone, basalt, high-silica, and fiberglass fire blanket materials?

Accepted Answer

The material determines the temperature resistance and the appropriate use case. Fine-spun fiberglass fire blankets offer strong value for money and suit everyday household kitchens. Silicone-coated fire blankets have a surface that better resists grease, is easy to clean, and feels good to the touch. Basalt fiber is naturally flame-retardant with higher temperature resistance, making it well suited to more demanding commercial kitchens. High-silica fire blankets stand out for their high-temperature resistance and are ideal for industrial, electrical, and other high-heat environments. Zhongjiawoan supplies all four boxed fire blanket types: fiberglass or silicone is fine for home use, while basalt or high-silica is recommended for high-temperature commercial and industrial scenarios.

Question 18

What national standard do Zhongjia Wo'an's fire blankets meet? Are test reports available?

Accepted Answer

Yes. Zhongjia Wo'an's fire blankets, including boxed silicone fire blankets, basalt fire blankets, high-silica fire blankets, and bagged worsted fiberglass fire blankets, are manufactured in accordance with the relevant requirements of national standard GB/T 17919 and the technical specifications for fire blankets. We provide test reports issued by third-party testing agencies covering metrics such as fire-resistance temperature, flame retardancy, and coverage fire-suppression performance. At the time of purchase, you may request the test report for the corresponding batch for use in acceptance inspection, fire safety inspections, or filing purposes.

Question 19

Where in the car should you keep a vehicle fire blanket and an in-car fire extinguisher?

Accepted Answer

In-car firefighting equipment should be kept somewhere the driver can reach and where it is securely fastened; we recommend under the driver's seat, in a door pocket, or in a dedicated mounting spot in the trunk to prevent it from sliding around while driving. Zhongjia Woan's vehicle fire blanket is compact and heat-resistant, and can cover a burning engine compartment or wrap a burning battery, making it a practical fit for both new-energy vehicles and gasoline vehicles. The low-temperature 550ml simple water-based extinguisher is well suited to in-car use. Never leave an extinguisher exposed to prolonged sunlight under the rear windshield, as high heat degrades its performance and safety.

Question 20

Do high-rise escape products such as descent devices and escape ropes require regular maintenance and servicing?

Accepted Answer

Yes. Zhongjia Wo'an's TH-30 series descent devices (Standard, Sleek Black, and Chrome-Plated Flagship editions), high-rise descenders, figure-8 descent devices, composite steel-core ropes, lightweight safety ropes, escape ropes, pants-style safety harnesses, and similar items are load-bearing safety products. We recommend inspecting them every six months to one year: check the ropes for wear, broken strands, or mold; check metal components for corrosion or deformation; and verify that the braking mechanism operates smoothly. Products that have undergone an actual descent, sustained a noticeable impact, or been stored in a humid environment warrant special scrutiny. If any abnormality is found, take the product out of service immediately and contact customer service to assess replacement. Never overload the device or use it beyond its service life.

Question 21

What fire safety equipment should I keep in my car, and how do I choose between a vehicle fire blanket and a car fire extinguisher?

Accepted Answer

The risk of a vehicle catching fire spontaneously or in a collision should not be underestimated, so it is advisable to keep firefighting tools in the car at all times. Zhongjiawoan's vehicle fire blanket is compact and foldable for storage in the trunk; it can cover engine-compartment or wheel-hub fires and also help control the temperature and isolate an electric vehicle battery fire. You can also carry a small portable water-based or dry powder fire extinguisher for emergencies. Compared with keeping only a fire extinguisher, a vehicle fire blanket is more specifically targeted at new-energy vehicle battery thermal-runaway scenarios, so using the two together is safer. Be sure to check the expiration date periodically and keep the equipment securely fastened.

Question 22

When buying fire protection products, how can I confirm that the test reports and certificates are genuine and valid?

Accepted Answer

Verify in three steps. First, check the certificate status: log in to the official CCCF website or the National Certification and Accreditation Information Public Service Platform (cx.cnca.cn), enter the certificate number, and confirm that it is valid, unexpired, and not revoked. Second, verify the information: compare the company name, product model, and specifications on the certificate against the actual product to ensure they match. Third, check the report: the test report should be issued by an agency holding CMA/CNAS qualifications, and the report number can be verified directly with the issuing agency. Zhongjia Wo'an provides authentic certificates and reports with every shipment, and we welcome item-by-item verification.

Question 23

Where do you install fire barrier bags (firestop pillows) and fire-resistant putty, and how do you use them correctly?

Accepted Answer

Fire barrier bags and fire-resistant putty are mainly used to seal gaps such as cable trays, pipe penetrations through walls, and the wire entry and exit points of distribution boxes, in order to stop flames and smoke from spreading. Zhongjia Woan's fire barrier bags simply need to be stacked and packed to fill the opening; the 2kg organic fire putty and sealing putty are hand-molded, then pressed firmly into the gap and can be removed and adjusted at any time. When installing, pack them solidly with no voids; they are commonly used at household low-voltage boxes and around pipes penetrating kitchen and bathroom walls. These materials cure at room temperature and require no tools, so ordinary households can install them themselves.

Question 24

If I find a quality problem after receiving a product, can I return or exchange it, and what is the process?

Accepted Answer

Zhongjia Wo'an supports returns and exchanges as provided by law. Please inspect your order upon delivery. If you find a damaged cylinder, air leakage, missing accessories, or an obvious cosmetic defect, please take photos as evidence and contact customer service promptly. For issues involving product quality or shipping damage, you may request a return or exchange within the specified period, and we will bear the corresponding responsibility. Returns for personal reasons require that the item remains suitable for resale. For safety reasons, safety products such as fire extinguishers and respirators are generally not eligible for no-reason returns once opened, used, or discharged. Specific terms are governed by the platform's or contract's after-sales provisions.

Question 25

How does choosing a fire extinguisher differ between home and commercial/industrial settings?

Accepted Answer

For home use, the emphasis is on being lightweight, easy to operate, and residue-free; typically you would choose a 2-6L portable water-based fire extinguisher or a fire blanket, with one or two units providing adequate coverage. Commercial and industrial premises have large floor areas and high fire loads, so they must be equipped in accordance with the relevant GB standards; large-capacity cart-mounted units are common, such as Zhongjiawoan's 25L cart-mounted water-based fire extinguisher, or multiple units distributed across the site, supplemented with dry powder, aerosol, and other agents based on the type of combustible materials present. Industrial environments must also consider passive fire-protection measures such as fire-stopping materials and fire pillows. Equipment selection should be determined comprehensively based on the nature of the premises, the floor area, and fire-safety acceptance requirements.

Question 26

What certification do automotive fire blankets and vehicle fire extinguishers need? Can they be used for the annual vehicle inspection?

Accepted Answer

Vehicle fire extinguishers must pass CCCF certification to be compliant. Fire safety equipment is one of the items checked during the annual vehicle inspection, so we recommend choosing a certified portable dry-powder or water-based extinguisher that is within its service life. Automotive fire blankets are not currently subject to a mandatory CCCF catalog requirement, but they should have an enterprise standard and third-party flame-retardancy and temperature-resistance test reports. Zhongjia Wo'an's automotive fire blankets have passed high-temperature-resistance testing, and our vehicle fire extinguishers are manufactured to national standards. Test reports are available, meeting the needs of everyday in-vehicle storage and annual-inspection compliance.

Question 27

Where should a descent device be installed, and what should a household prepare in advance?

Accepted Answer

A descent device is best installed at a fixed anchor point in a high-rise residence, such as a window or balcony, with the hook base securely anchored to a load-bearing wall or a dedicated expansion bolt. Zhongjia Woan's TH-30 series descent devices (Standard, Sleek Black, and Chrome Flagship editions) come with a safety harness, rope, and hook; in an emergency, the user simply puts on the harness and descends at a steady, controlled speed to escape. We recommend keeping the equipment in an easily accessible spot in the bedroom and reading the manual to confirm the rated load capacity and the applicable floor height. Never exceed the load limit or use it for everyday recreation.

Question 28

What should I do if an alarm or detector fails, and how many years does a smoke alarm typically last?

Accepted Answer

Zhongjia Wo'an smoke alarms, carbon monoxide alarms, and combustible gas detectors (methane) are eligible for repair or replacement during the warranty period for non-user-caused failures. For these electronic products, we generally recommend a monthly self-test using the test button and periodic dust cleaning; battery-powered models require timely battery replacement. Sensors have a limited service life: smoke detectors generally need whole-unit replacement after 5 to 10 years, and gas and CO detectors after about 5 years. Once a unit has exceeded its service life and its sensitivity declines, it should be replaced promptly. If you experience frequent false alarms, a failed self-test, or an end-of-life notification, please contact customer service for assistance.

Question 29

What is a controlled descent device, and do high-rise residences really need one?

Accepted Answer

A controlled descent device is a high-altitude escape device that uses a rope and a speed-limiting mechanism to lower a person from a window or balcony to the ground at a safe speed, making it ideal for emergencies where the stairwell is blocked by smoke and fire and normal evacuation is impossible. It is recommended for high-rise residences, apartments, hotel guest rooms, and similar spaces. Zhongjiawoan's TH-30 descent device is available in a standard version, a black edition, and a chrome-plated flagship version, complete with a pant-style safety harness, escape rope, and other accessories. When purchasing, pay attention to the applicable floor height and load capacity, and familiarize yourself with the installation point and operating method in advance so it is ready when it matters most.

Question 30

Do firestop materials such as fire pillows and fire-resistant putty have mandatory certification or a national standard?

Accepted Answer

Yes, there is a national standard. Firestop materials are governed by GB 23864 (Firestop Materials). Fire pillows, organic fire-resistant putty, and sealing mastic fall within the scope of this standard and must meet requirements such as fire-resistance rating, expansion performance, and smoke toxicity, as well as pass type testing. At present, these products are primarily judged by their conformity to the national standard and by third-party test reports, with some brought under fire protection market-access management. Zhongjia Wo'an's fire pillows, organic fire-resistant putty (2 kg), and sealing mastic are all manufactured in accordance with the relevant requirements of GB 23864, and test reports are provided.

Question 31

At what height should household smoke alarms and gas alarms be installed?

Accepted Answer

Smoke alarms should be mounted on the ceiling of bedrooms and the living room; since smoke rises, mounting them up top is most sensitive, and you should keep the area within 0.5 meters clear of obstructions. Gas detectors depend on the gas's density: Zhongjia Woan's combustible gas detector (methane) is designed for natural gas, which is lighter than air, so it should be installed within 30 centimeters of the ceiling above the stove; if you use LPG (which is heavier than air), the alarm should be installed low, about 30 centimeters above the floor. A carbon monoxide alarm can be installed at a mid-level height near the breathing zone. Press the test button periodically to check it.

Question 32

Do firestopping materials such as fire pillows (fire bags) and firestop putty have a shelf life, and do they need to be replaced?

Accepted Answer

Zhongjia Wo'an's firestopping materials—including fire pillows, 2kg organic firestop putty, and sealing mastic—can be stored long term in a sealed, dry environment, but they age over time once installed and in service. We recommend periodically inspecting sealed areas for cracking, detachment, hardening with loss of flexibility, or loss of intumescent (expansion) performance. If any material is found to have failed, replace it promptly to keep the firestopping of cable shafts and pipe penetrations effective. For bulk purchases, if you have questions about storage or replacement intervals, please contact customer service to obtain product technical data and maintenance recommendations.

Question 33

How do I choose among the standard, black, and flagship versions of the TH-30 descent device?

Accepted Answer

All three versions share the same core descent mechanism; the main differences lie in the materials, craftsmanship, and level of configuration. The standard version meets routine household escape needs and offers strong value for money. The black edition has a more refined appearance and upgraded workmanship, making it suitable for users who value quality. The chrome-plated flagship version uses higher-grade materials and more thorough anti-corrosion treatment, making it well suited to commercial procurement for hotels and apartments or to scenarios with high durability requirements. When purchasing, first confirm that the floor height and load capacity are a match, then choose the tier according to your budget and frequency of use; for personal home use, the standard version is more than adequate.

Question 34

What certifications must high-altitude escape and life-saving equipment—such as descent devices, escape ropes, and safety harnesses—pass?

Accepted Answer

Escape descent devices are governed by national standard GB 21976.4 (Escape and Rescue Equipment for Building Fires — Part 4: Escape Descent Devices). They are a fire protection market-access product, must pass type testing, and should be checked against metrics such as rated load, descent speed, and rope strength. Work-protection equipment such as safety ropes, safety harnesses, and figure-eight descenders should comply with the applicable labor-protection or fall-protection national standards. Zhongjia Wo'an's TH-30 series descent devices, escape ropes, trouser-style safety harnesses, and composite steel-core ropes are all manufactured to the corresponding national standards and come with accompanying test reports, so they can be used with confidence in both home and high-altitude settings.

Question 35

How often should a household hold a fire drill, and how do you organize one?

Accepted Answer

We recommend holding a household fire drill every six months to once a year, focusing on making family members familiar with escape routes and where the fire extinguisher and descent device are kept. The drill can simulate a kitchen fire: practice operating the extinguisher with the Pull-Aim-Squeeze-Sweep sequence, pulling out a fire blanket to cover the fire source, and rehearse crouching low while covering your nose and mouth as you evacuate along the escape route to a safe assembly point. High-rise residents should also practice using the descent device and escape rope. Zhongjia Woan recommends checking after each drill that all equipment has been returned to its place and that pressures are normal. Make fire drills a family habit so no one panics when it counts.

Question 36

Will automotive fire blankets and in-vehicle fire suppression products fail if left in a hot car for a long time, and how should they be maintained?

Accepted Answer

Zhongjia Wo'an automotive fire blankets are made from high-temperature-resistant fiber materials, but the high summer temperatures and direct sunlight inside a vehicle can still accelerate aging of the outer packaging. We recommend storing them somewhere that avoids direct sunlight, such as the trunk, and periodically checking for damage, contamination, or moisture-induced clumping. For onboard products such as automatic fire suppression devices, fire shields, and portable aerosol fire extinguishers, also keep an eye on the service life and cylinder condition; replace any unit promptly if it has exceeded its service life or if the gauge needle is not in the green zone. In general, simply keep the products clean and their packaging intact, and if you notice any abnormality, contact customer service to inquire about replacement.

Question 37

How does a controlled descent device differ from an escape rope or a figure-eight descender, and which is better for the average household?

Accepted Answer

A controlled descent device features an automatic speed-limiting mechanism that keeps the descent smooth and controllable; it requires no specialized skill, and even elderly people and children can use it after brief instruction, making it the best fit for high-altitude escape in the average home. Escape ropes, figure-eight descenders, and high-altitude descenders are mostly used by professional rescuers or people with training, as they require a degree of arm strength and operating experience, making them riskier for ordinary households. If your priority is safety and ease of use, choose the TH-30 descent device with a pant-style safety harness first. An escape rope can serve as a supplement for lower floors or be used together with a safety harness, but relying on a figure-eight descender alone without training is not recommended.

Question 38

If products are being exported overseas, are international certifications such as CE required in addition to CCCF?

Accepted Answer

Yes. CCCF is the mandatory certification for domestic sales, while exporting to the EU market requires compliance with CE certification requirements (for example, protective PPE under EU Regulation EU 2016/425, and fire extinguishers under standards such as EN 3). Exporting to other regions may involve local market-access certifications. Zhongjia Wo'an spans four major systems—fire safety, water rescue, medical protection, and outdoor protection—and export products such as protective clothing, cut-resistant gloves, buoyancy vests, and respirators can be matched to the applicable certifications according to the requirements of the target market. Please contact our sales team to confirm the specific list of certificates required.

Question 39

When an organization or community holds a fire drill, what emergency protective equipment should be prepared?

Accepted Answer

Before organizing a fire drill, you should have a full set of equipment ready for fighting incipient fires and for self-rescue escape. For the firefighting portion, you can use Zhongjia Woan's portable or 25L wheeled water-based extinguishers and fire blankets; for the escape portion, prepare filter-type or chemical-oxygen fire self-rescue respirators for smoke protection, and for high-rises, add descent devices, escape ropes, and trouser-style harnesses. Also keep a combination first-aid kit on hand to treat minor bumps and scrapes during the drill. Before the drill, check every extinguisher's pressure and validity period and the seal integrity of each respirator's packaging, so the equipment is genuinely usable and participants get hands-on practice rather than just going through the motions.

Question 40

Do you offer on-site installation or on-site inspection services, for example for fire hydrant insulation covers and firestopping materials?

Accepted Answer

For bulk purchases by engineering projects and enterprises, Zhongjia Wo'an can provide value-added services such as on-site surveys, installation guidance, and acceptance support in accordance with the contract, covering scenarios such as fire hydrant insulation cover installation, firestopping construction, and fire extinguisher configuration planning. Individual retail orders are generally handled through logistics delivery plus remote guidance. If you require on-site service, please provide the project address, product list, and quantities, and contact customer service to assess feasibility and cost. We will arrange service coordination with a provider near you.

Question 41

How do I choose an alarm, and what's the difference between a smoke alarm, a carbon monoxide alarm, and a combustible gas detector?

Accepted Answer

The three monitor different targets and should be deployed separately according to risk. A smoke alarm detects the early smoke of a fire and is suited to bedrooms, living rooms, and hallways, forming the foundation of household fire warning. A carbon monoxide alarm addresses the risk of CO poisoning from incomplete combustion of gas or charcoal fires, making it suitable for rooms with gas water heaters or heating appliances. A combustible gas detector (methane) monitors natural gas leaks and is best installed near the gas stove or piping. Zhongjiawoan offers a complete range of all three alarm types: we recommend a combustible gas detector for the kitchen, a smoke alarm for the bedroom, and adding a CO alarm wherever gas appliances are present.

Question 42

How do you store and use a fire self-rescue respirator, and can it be reused?

Accepted Answer

A fire self-rescue respirator should be stored where you must pass during an escape, such as the bedroom bedside or near the door, kept away from heat and humidity, with attention to the packaging seal and validity period. To use it, tear open the vacuum packaging, remove the two nose clips or sealing plugs at the front and back, pull it over your head, and tighten the head straps to filter toxic smoke as you escape. Zhongjia Woan's filter-type respirator is suitable for ordinary smoke conditions, while the chemical-oxygen respirator generates its own oxygen supply in oxygen-deficient, heavy smoke and offers longer protection. All respirators are single-use and become invalid once the seal is broken; after escaping, the entire unit must be replaced. Never take one back and store it for reuse after a drill.

Question 43

Can fire escape respirators and first aid kits still be used after they expire, and what should I do when they reach the end of their service life?

Accepted Answer

Using expired products is not recommended. Zhongjia Wo'an filter-type fire escape respirators typically have a service life of 3 to 5 years, and chemical-oxygen fire escape respirators approximately 3 to 5 years. Once opened or past their service life, their filtration/oxygen-supply performance can no longer be guaranteed and they may fail at a critical moment, so they should be replaced promptly according to the labeling. The dressings, disinfectant supplies, medications, and other items in a combination first aid kit each have their own shelf life; we recommend taking inventory annually and promptly replenishing or replacing expired items. Please do not discard expired respirators carelessly; contact customer service to learn about compliant recycling and disposal methods.

Question 44

How do I choose fire-stopping materials such as fire pillows, fireproof putty, and sealing putty, and where are they used?

Accepted Answer

These are passive fire-protection materials used primarily to seal wall penetrations for pipes, cables, and cable trays, preventing flames and smoke from spreading through the gaps. Fire pillows are suited to temporary or maintainable sealing of larger openings and cable trays and offer flexible installation. Organic fireproof putty (2kg) and sealing putty are used to fill the gaps around wires and cables; they are highly moldable and easy to work with. Zhongjiawoan offers fire pillows, organic fireproof putty, sealing putty, and more. Fireproof putty can be used to seal the gaps in household distribution boxes and low-voltage boxes, while a combination of fire pillows and fireproof putty is recommended for equipment rooms and industrial power-distribution scenarios.

Question 45

How should outdoor flood-control gear such as buoyancy vests and flood-control sandbags be stored and used?

Accepted Answer

Buoyancy vests should be stored in a well-ventilated, dry place, protected from sharp objects that could puncture them and from prolonged sun exposure. Before use, check that the buckles and zippers are intact; once on, tighten all straps to ensure a snug fit that will not slip off. They are suitable for water activities and flood-control rescue. Zhongjia Woan's flood-control sandbags are mostly the water-absorbing, expanding type: they take up little space when stored dry, and expand rapidly on contact with water to form a water-blocking wall that can be stacked to seal doorways and basement entrances. Before flood season, prepare an ample supply in advance and keep it in an easily accessible spot; after use, air-dry the bags and store them properly so they are ready for reuse next time.

Question 46

What should I keep in mind when maintaining and storing products such as buoyancy vests, flood-control sandbags, and protective suits, and how is the warranty determined?

Accepted Answer

Zhongjia Wo'an's water-related and protective products carry a warranty under normal use, covering non-user-caused material and workmanship defects. Recommended routine maintenance: rinse buoyancy vests with clean water and air-dry them after use, avoid prolonged direct sunlight and heavy compression, and regularly inspect the buoyancy material and buckle straps. Flood-control sandbags (water-swelling type) should be kept unopened in a dry place; once they have absorbed water in use, they are generally single-use. For protective suits and cut-resistant gloves, store them clean and check for damage. User-caused damage, normal wear, and single-use consumption are not covered by the warranty. For details, please refer to the warranty card.

Question 47

What protective gear should I bring for outdoor and water activities, and how do I choose a buoyancy vest and a first-aid kit?

Accepted Answer

Outdoor and water activities center on preventing drowning and responding to sudden injuries. For water rescue or wading scenarios, you should wear a buoyancy vest to provide extra buoyancy and ensure safety. For outdoor hiking and camping, we recommend carrying a combination first-aid kit to handle common injuries such as cuts and sprains, along with cut-resistant gloves to prevent injury when handling sharp tools. Around its water-rescue, outdoor-protection, and medical-protection systems, Zhongjiawoan offers buoyancy vests, combination first-aid kits, cut-resistant gloves, and more. When purchasing, choose the first-aid kit size based on the intensity of the activity and the number of people, and for water-based activities always prioritize a compliant buoyancy vest.

Question 48

What is a fire self-rescue respirator for, and how do I choose between the filtering type and the chemical oxygen type?

Accepted Answer

A fire self-rescue respirator is used to prevent the inhalation of toxic smoke during fire escape and is an important piece of equipment for evacuating high-rise buildings and public spaces. A filtering fire self-rescue respirator uses a filter canister to remove harmful components from the smoke; it is simple in structure, quick to put on, and low in cost, making it suitable for routine escape in homes, hotels, and offices. A chemical oxygen fire self-rescue respirator generates its own oxygen and does not depend on the surrounding air, making it suitable for enclosed spaces that are oxygen-deficient or heavily filled with smoke. Zhongjiawoan supplies both types of respirators: the filtering type is sufficient for the average household, while the chemical oxygen type is recommended for underground spaces or high-risk environments. Be sure to check the expiration date.
