First, the structural characteristics of fire breathing apparatus
1. The hood is made of flame retardant It is made of cotton cloth and coated with aluminum foil film to resist heat radiation and prevent the injury of the escapee’s head from high temperature radiation in the fire field.
2. The hood is provided with a large transparent window, which provides a wide field of vision and is easy to escape.
3. The surface of the hood is reflective due to the coating of aluminum foil, which is convenient for identifying the escapees under the thick smoke.
4. The half mask is made of soft rubber, which is comfortable to wear. Its shape and size are suitable for various face shapes, and it has good air tightness, preventing toxic fumes from directly entering the respiratory organs through channels other than the filter canister .
5. The canister has a filter layer and a smoke filter layer. The filter layer is made of catalyst and impregnated with high-quality activated carbon, and the smoke filter layer is made of ultra-fine fiber material, which can effectively prevent poisonous smoke and poison Fog, carbon monoxide, hydrogen cyanide, hydrogen chloride, acrolein, hydrogen fluoride, nitrogen oxides, hydrogen bromide, sulfur dioxide and common poisonous gases in fires cause harm to people.
6. The air inlet and outlet of the canister are sealed with soft rubber, and the sealing is reliable for a long time to ensure that the performance of the product remains unchanged within the validity period.
Second, the technical indicators of fire breathing apparatus
1. Protection time: XHZLC40 type 40min.
2. Inhalation resistance: no more than 800pa at 95L/min.
3. Exhalation resistance: no more than 300pa at 95L/min.
4. Oil mist transmission coefficient: not more than 5%.
5. Inhalation temperature: 0.25% carbon monoxide not more than 65℃.
7. Wearing weight: no more than 1000g.
8. Carbon monoxide protection concentration 0～1.0%.
9. Dimensions of a single product box: 210mm*140mm*111mmm.
Three, the use of fire breathing apparatus
1. When a fire occurs, immediately open the box cover along the direction of the opening sign of the box, and tear the package Bag to remove breathing apparatus.
2. Pull out the front and rear two red sealing plugs along the reminder belt.
3. Put the respirator on the head, tighten the headband, and quickly escape from the fire.
Four. Product use of fire-fighting breathing apparatus
1. It is used for coal mine underground operators in the event of natural disasters such as fire, gas explosion or gas outburst. And when the respirator fails, the ambulance team can safely withdraw from the disaster area for use.
2. It is used by the chemical department when toxic and harmful gases escape.
3. It is used when a large amount of natural gas or other toxic gases are protruding during oil extraction operations.
4. It is used for high-rise buildings, when people in the building wear to escape or wait for rescue in the event of a fire.
5. Use by firefighters or other departments in toxic and harmful gas or oxygen-deficient environment and other rescue use.
