Regulations on pre use training of air breathing and chemical protective clothing

1n some economical light pollution and high pollution, it is inevitable that we will use some air breathing apparatus and use chemical protective clothing to reduce pollution. Of course, the times are progressing, so are our products? 1n order to reduce the pollution scientifically and effectively, we must know clearly what we need to pay attention to before using the gas mask, which can prevent the splashing of chemical polluted liquid and dust. 1t is sewn by ultra-thin butyl rubber cloth, and the seam is sealed with homogeneous adhesive tape. The following is the knowledge that environmentalists must master when they provide the vast number of usable products:

1. preparation work

2 sets of air respirators, 2 sets of chemical protective clothing, 2 sets of peace axe, 2 sets of battery safety lights, and 2 pieces of fire safety ropes2. Check before wearing

1) check the air tightness of the mask and whether the breathing is normal

2) check the pressure: turn on the cylinder switch, the pressure gauge should indicate between 28 ~ 30MPa (domestic air respirator), indicating that the pressure is normal

3) check the air tightness: turn off the gas cylinder switch and observe the reading of the pressure gauge. Generally, the pressure drop within 5 minutes is not more than 2 MPa, indicating that the air tightness of the gas supply system is in good condition. For example, the pressure drop of Shanghai Eger respirator should not exceed 0.5MPa within one minute

4) check the alarm function: generally, when the pressure drops to 6 ~ 4MPa, the alarm siren will sound, indicating that the alarm function is in good condition. 1nspection method: Take Shanghai Eger brand as an example, turn on the gas cylinder switch, when the pressure reaches the maximum value, turn off the gas cylinder switch, and then gently rotate the red knob (flushing valve) on the air inlet of the gas supply valve to deflate, when the pressure drops to 5 ± When the pressure is less than 0.5 MPa, the alarm whistle will sound, indicating that the alarm function is in good condition. At the same time, it is also a time to purge the alarm ventilation pipeline

3. Wearing procedure (two people cooperate)

1) the wearer of chemical protective clothing, for example, must first wear fireproof trousers and fireproof shoes when fighting a fire (the cooperator should help the wearer to stand firmly, and then give the wearer the safety belt from the back to the front), and then fasten the safety belt. At this time, the cooperator connects the fire rope with the safety belt, and the other end is fixed on the column

2) the cooperator holds the shoulder strap of the respirator on the wearer’s back (or the wearer kneels down on his right leg, squats on his left leg, first holds the right shoulder strap on his right elbow, then holds the respirator’s back frame with both hands, stands up and lifts it over his head, then releases his hand), and turns left 90 ° , 1n the face of those who cooperate, use your thumb to fasten the semicircular buttons on both sides of your chest, and then pull down the belt of your back frame to fasten your belt

3) the cooperator assists the wearer to put on the left sleeve of the fireproof clothing first, and then put the pressure gauge outside the clothing, and then put on the right sleeve

4) after the cooperator hangs the safety helmet around the wearer’s neck, the wearer immediately puts on the breathing mask. At this time, the cooperator helps the wearer fasten the fireproof clothes from bottom to top

5) the cooperator hands the fire gloves to the wearer in the order of left and right hands, and then hands the fire helmet to the wearer and button it up. After finishing, hands the hatchet and battery safety light to the wearer immediately, and the procedure is completed. Raising the right hand and walking correctly means that the whole operation process is completed. China labor insurance net
