1. It is strictly forbidden to store or temporarily place any combustion-supporting, flammable, or combustible items inside the explosion-proof shelter, and it is strictly forbidden to store or temporarily place highly corrosive items.。
   

2. During maintenance and repair, before entering the analysis shelter, personnel must turn on the flameproof axial-flow exhaust fan outdoors through the explosion-proof switch.。
   

3. When working inside the shelter, do not close the door completely.。If the door is closed and a dangerous or combustion abnormal state occurs, push the door push rod inside the shelter outward, and the door will open to protect personal safety.。
   

4. All explosion-proof electrical equipment inside the explosion-proof shelter is strictly forbidden to be disassembled, loosened, or opened while energized.。Only after power is cut off and the portable combustible gas alarm tests qualified can such operations proceed.。
   

5. If indoor and outdoor lighting or emergency lamps are found not to be lit, after powering off and checking that there is no combustible hazardous gas in the environment, replace the bulb or fluorescent lamp.。
