Purchasing Notes: For personal water safety, prioritize a life jacket; for general scenarios, choose a basic buoyancy vest; for flood emergencies in garages or shops, prioritize water-absorbent expansion sandbags; for long-term repeated use, opt for traditional canvas flood control sandbags; for outdoor tent ballast, choose windproof fixed sandbags; for protecting valuable equipment from rain and flooding, use a flood control cover.
II. Correct Usage and Operation Methods
① Buoyancy Vest / Life Jacket (Four Steps: Put On Adjust Fasten Check)
Title: Fire Safety Science · Four-Step Operation for Buoyancy Vest (Life Jacket)
1. Put On: Slip the vest over your body, and fit the shoulder straps to your shoulders.
2. Adjust: Tighten the adjustment webbing at the waist and hem so that the vest fits snugly against your torso without excessive looseness that causes it to shift.
3. Fasten: Fasten all buckles and confirm they are fully locked; for the life jacket, verify that the audio-visual positioning switch can be activated normally.
4. Check: Pull all webbing to confirm it is secure, ensure the reflective strips face outward; inspect for any damage before entering water.
Bottom dark blue prompt bar:For self-rescue when falling into water only, cannot replace professional rapid current rescue equipment; be sure to check the integrity of the buckles before entering water.
② Flood Control Water Barriers (Traditional Sandbags / Water-Absorbent Expanding Sandbags) Operation
1. Traditional canvas flood control sandbags: Fill with sand and soil to 70-80% full, tighten the drawstrings; stack in a staggered pattern, pressing seams together layer by layer like building a brick wall, and build a water barrier with lower outer edges and higher inner edges. Do not fill the sandbags completely.
2. Water-absorbent expanding sandbags: Unpack the outer packaging, place in a water accumulation area or spray with water, wait for 3-5 minutes to fully expand, and arrange closely in a staggered pattern to form a water barrier.
Prompt: Water-absorbent expanding sandbags cannot be dried and reused as water barriers after being fully saturated with water. New products that have not come into contact with water can be stored for later use.
③ Wind-Resistant Fixed Sandbags: Fill with sand and gravel, tighten the bag opening, loop the straps around tents and enclosure columns, fasten with hook-and-loop fasteners, and distribute multiple sets evenly as counterweights to resist strong winds.
④ Flood Control Covers: Fully cover the equipment and supplies that need protection, tie and tighten the edges, and press down the bottom to prevent rainwater from seeping in and being blown away by strong winds.
III. Key Points for Use and Storage
Usage Notes
1. Flotation products: Do not use sharp objects to scratch or cut the foam and fabric; replace the battery of the lifebuoy's acoustic and visual position indicator when it expires;Modifying or cutting the flotation foam is strictly prohibited, as it will directly reduce buoyancy.
2. Flood control sandbags: Do not overfill traditional sandbags; filling them to 70-80% capacity allows them to fit tightly against the ground and reduce water seepage through gaps; stack them in a staggered pattern and compact them firmly.
3. Water-absorbent expansion bags: Keep their outer packaging sealed and dry before use; after they have absorbed water and expanded, dispose of them as waste after the flood and do not reuse them for flood control.
4. Wind-resistant fixed sandbags: Only use them as counterweights; do not use them as flood control sandbags.
5. Flood control covers: Avoid sharp edges and corners to prevent the fabric from being torn; do not expose them to direct water pressure; use them only for covering and protection.
Storage Guidelines
1. Store all water rescue equipment in an indoor, dry, and well-ventilated warehouse; keep them away from direct sunlight, oil stains, and acid and alkali chemicals.
2. Life vests, immersion suits: Store hanging, do not fold under heavy pressure, and avoid long-term compression, aging and deformation of the buoyancy foam; pay special attention to the validity period of the battery components.
3. Canvas sandbags, inflatable bags: Store in a moisture-proof and sealed place; for inflatable bags, moisture protection is key—if they get damp early, they will fail early.
4. Flood control covers, windproof sandbags: Fold for storage, and avoid sharp objects from puncturing or tearing the fabric.
IV. Daily Inspection and Scrap Standards
Daily Inspection (It is recommended to inspect every quarter, and a comprehensive check must be conducted before the flood season arrives)
1. Life vests / immersion suits: The fabric has no tears or holes; the buoyancy foam has no crushing, powdering or shedding; all buckles open and close smoothly; webbing and stitching are not frayed; reflective strips are intact; for immersion suits, check the sound-light positioning device and whether the battery is within the validity period; identification labels are complete and clear.
2. Flood control sandbags (canvas): The canvas has no large-area abrasion or cracking; the drawstring is intact with no mold or rot.
3. Water-absorbent Expansion Bag: The outer packaging is intact with no damage, no prior moisture or water ingress, and no bag swelling; product markings are complete.
4. Wind-resistant Fixed Sandbag: The Oxford fabric has no tears, and the straps and Velcro are intact with no aging or brittleness.
5. Flood Control Cover: The PVC fabric has no cracks or brittleness, and the binding straps are complete.
If any of the following occurs, it must be scrapped and replaced
1. The foam of the buoyancy vest is crushed and pulverized, the fabric has holes or tears; the buckles are damaged and ineffective; the personal locator device is damaged, and the buoyancy drops significantly, making it impossible to maintain a floating posture.
2. The canvas sandbag has large-area tears, mold, or rot, and large areas of stitching are coming loose.
3. The outer packaging of the water-absorbent expansion bag is damaged, it has pre-expanded due to prior moisture, and has lost its emergency use capability.
4. Windproof sandbag fabric cracked, Velcro completely aged and failed, unable to be fixed.
5. Flood control cover fabric cracked and torn in large areas, unable to provide coverage and waterproofing.
6. The product has been soaked and corroded by floodwater for a long time and contaminated by chemicals; the label and nameplate have fallen off, making the model unidentifiable.
Notes: There is no unified national mandatory scrapping age for water area flood control equipment. It shall be subject to the actual inspection status. A complete inspection must be conducted before the flood season, and damaged items shall be replaced immediately.
V. Selection and Application Summary
1. Self-rescue for personnel falling into water: Operators should prioritize the use of Water Rescue Buoy (with sound and light alarm and positioning function); basic life vests are selected for regular patrols and shore protection.
2. Garages, shops, and first-floor residents facing sudden waterlogging during the flood season: Prioritize water-absorbent expansion bags, which can be quickly deployed without filling with sand.
3. Properties and work units require repeated flood control operations: Choose traditional canvas flood control sandbags.
4. Wind-resistant ballast for outdoor tents and barriers: Use wind-resistant fixed sandbags; not for water blocking.
5. Protection of computer rooms and valuable outdoor equipment from rain and flooding: Equip with flood control covers for shielding and protection.
Important Reminder: Water-related equipment is only for protection. When flood season arrives, prioritize evacuating personnel; do not rely solely on supplies to stay and fight the flood.
