Explosion-proof cabinets mainly prevent fires or explosions caused by leakage of dangerous chemical liquids, and play a role in preventing fires and explosions. It should be noted that highly corrosive chemicals should not be placed in cabinets such as flammable and combustible goods. Special corrosive chemical cabinets must be purchased and kept. The international standard is to be in a calcination test furnace at 1000 degrees Celsius, and the temperature in the cabinet should be kept below 55 degrees Celsius for at least 1 hour. The magnetic medium file is not damaged, and the information can be completely saved and read immediately. The airflow principle is the same as that of the laboratory fume hood, except that the exhaust port is equipped with a HEPA filter. Safety precautions for explosion-proof cabinets.
The land where the explosion-proof safety cabinet is placed must be horizontal. If multiple explosion-proof safety cabinets are placed side by side, the distance between each cabinet must be less than 15 cm, and the explosion-proof safety cabinet should be placed away from open flames or other equipment that are heated and splashed by chemical liquids or slag. There is an electrostatic conduction strip at the lower corner of the right outer wall of the cabinet.
If the cabinet layout is correct, the electrostatic ground wire should be connected in time to guide the static electricity accumulated in the cabinet to ensure that the materials placed on the cabinet countertop will not exceed the load limit of the countertop.
If there are multiple layers on the board, the items should be placed in a way that larger or heavier items are placed on the upper layer, and smaller or lighter items are placed on the lower layer. If the explosion-proof safety cabinet is located in a closed and narrow space, or the place where the cabinet is placed has strict restrictions on the volatilization of flammable liquids, a ventilation system should be set up at the connection of the cabinet ventilation holes to discharge the flammable liquids accumulated in the cabinet according to the volatilization situation. Liquid, at night or under low light conditions.
If you need to put things in the cabinet or do other work, you should turn on the lights around or use an explosion-proof flashlight. It is strictly forbidden to light candles, alcohol lamps or use lighters near the cabinet, which may cause combustion and explosion.
