Hazardous properties of calcium carbide
Thread Content
Calcium carbide is a hazardous chemical. Its danger lies in the fact that it readily produces acetylene when in contact with water, and acetylene is a flammable and explosive gas, which results in high risks. Since danger arises only in the presence of water, then by controlling water and storing and transporting calcium carbide in such a way that it does not come into contact with water, the risk can be controlled. Why must the area where calcium carbide is stored be treated as a Class A fire and explosion hazard area? The calcium carbide production facilities and the areas surrounding them are all high-temperature zones; in fact, calcium carbide is still bright red right after it is produced. Is it necessary to require explosion-proof properties for the equipment and tools used for transporting and handling calcium carbide?
The calcium carbide furnaces in the areas where calcium carbide is produced are open-flame equipment of Class D, and no explosion protection is required
Calcium carbide dust may also be present in the area where calcium carbide is stored
Got it; the calcium carbide production area is classified as Class D. The storage area becomes Class A. Thank you for the tip: handshake
Does calcium carbide fall under Category A2 or Category A3?
Take a look at GB50016 – it falls under category A4
The storage classifications are listed in Category A2. This is directly related to the warehouse’s floor area and fire compartments. The information held by experts in different provinces varies.
Class A is just Class A. I might not quite understand what you mean; if it’s not described using a standard list and there are other categories, please indicate the source.
Apart from the distinction between Class A and Class B, as well as the arrangement in order according to the standard list, I really might not understand what you mean by Class 2 and Class 3:L
