Fire protection gas mask

Fire gas mask is a kind of personal protective equipment used to effectively protect the respiratory organs, eyes and facial skin. The utility model can be directly connected to the gas mask and the gas guiding tank, and can be directly connected to the tracheal guiding tank. According to the protection requirements, fire-proof gas masks can be used in chemical industry, warehouses, scientific research, and various toxic and harmful working environments.

Instructions:

1. Check the air tightness of the entire mask before use. The method is as follows: connect the mask to the rear canister, put on a gas mask, block the air inlet of the canister with your hand or a rubber plug, and take a deep breath. If no air enters, the mask is airtight and can be used. Otherwise, it should be repaired or replaced.

2. Connect the gas mask: first unscrew the lid of the canister, then connect the canister under the mask, and remove the rubber plug of the air inlet at the bottom of the canister.

3. If the wearer smells the faint smell of poison gas, he should leave the poisonous area immediately.
