Whether to use explosion-proof electrical equipment in yellow phosphorus places
Thread Content
Are explosion-proof electrical appliances used in yellow phosphorus locations? According to the safety data sheet of yellow phosphorus: Operation and handling precautions: Close the operation and provide adequate local exhaust. The operation should be as mechanized and automated as possible. Operators must undergo special training and strictly abide by operating procedures. It is recommended that operators wear self-priming filter gas masks (full face masks), tape gas-proof clothing, and rubber gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid contact with oxidants, acids, and halogens. When handling, load and unload with care to prevent damage to packaging and containers. Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may contain harmful residues. Storage precautions should be stored in water and must be submerged under water and isolated from air. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. They should be stored separately from oxidants, acids, halogens, and food chemicals, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. Suitable materials should be available in the storage area to contain spills. The "five pairs" management system for extremely toxic substances should be strictly implemented. Both of the above items mention the use of explosion-proof ventilation systems and equipment. Are there any companies that use explosion-proof electrical equipment?
Yellow phosphorus is a self-igniting substance that is highly toxic and irritating. It can spontaneously ignite when exposed to air and cause combustion and explosion. Explosion-proof electrical appliances should be used.
Friends upstairs, do you have any evidence? Are there any standards and regulations? ? ?
You can check the Ministry of Construction of the People's Republic of China GB50058-1992 "Code for Design of Electrical Installations in Explosive and Fire Hazardous Environments"
The people upstairs are a bit blundering. I checked the appendices in GB50058-1992 "Code for Design of Electrical Equipment in Explosion and Fire Hazardous Environments" and "General Guidelines for Preventing Static Electricity Accidents" GB12158-2006. I could not find the explosion-proof group and level of yellow phosphorus. In other words, I could not find the basis for using explosion-proof electrical appliances.
Yellow phosphorus is a solid that spontaneously ignites when exposed to air. What kind of explosion can it prevent? Sir, there may be something wrong with the "Safety Technical Instructions" you quoted.
Your understanding is too narrow. The attached table is just a few examples. Do you only need to refer to the attached table for specific explosion-proof area divisions and explosion-proof electrical appliance selection? This is a serious technical exchange forum, please pay attention to your language expression
The use of explosion-proof electrical appliances is to prevent ordinary electrical appliances from igniting flammable gases or steam. Yellow phosphorus ignites when exposed to air, and there is no problem of flammable steam being ignited by electrical appliances. There should be no need for explosion-proof electrical appliances.
I also want to know, hoping that some professionals can give a conclusion.
GB50058-1992 "Code for Design of Electrical Installations in Explosion and Fire Hazardous Environments" This code does not apply to the following environments: 5. Environments using strong oxidants and substances that can catch fire without external ignition sources
The level is a bit low. I apologize for not being able to give more ratings. Need to learn recently * Yellow phosphorus related knowledge, come here to learn * .
