Chemical Oxygen Fire Self-Rescue Respirator in Paper Box
Chemical Oxygen Generation Technology——Uses potassium superoxide as oxygen source, closed-circuit breathing system isolates external smoke.
Flame-Retardant Material and Anti-Thermal Radiation——Hood resists thermal radiation, keeping head and face safe in high heat.
Large Viewing Window with Reflective Strips——Clear field of vision; reflective at night for easy search and rescue identification.
Tear open the paper box, remove the respirator, and check that the air reservoir bag is intact.
Pull the activation ring firmly or press the firing mechanism to initiate the oxygen-generating chemical reaction.
Place the facepiece over the head, insert the mouthpiece into the mouth, pinch the nose clip closed, and pull the head harness tight.
Breathe through the mouthpiece with your mouth, ensuring the nose clip completely seals the nostrils to prevent inhalation of external smoke.
After breathing is steady, leave quickly along the safety passage; do not remove the mask midway.
Keep the potassium superoxide oxygen-generating agent strictly away from water or moist air. Store sealed and dry.
Inspect the outer packaging seal monthly. If beyond the 4-year expiration, scrap immediately.
Be sure to pinch the nose clip tight when wearing. Breathe only through the mouth to prevent external toxic gases from entering.
If you feel abnormal breathing resistance or heat during use, evacuate immediately but do not remove the mask.
