Issues regarding the selection of fire extinguishers for high-voltage rooms
Thread Content
Currently, many distribution rooms with a voltage of over 10 KV are still equipped with ABC dry powder fire extinguishers, whose voltage resistance rating is 5000 V. Our manager refuses to have them replaced; could those with more experience share their approaches?
This one of mine is also from ABC. What do you mean by a voltage tolerance rating of 5000V?
It’s on the fire extinguisher – the insulation rating!
An ABC fire extinguisher will do; we use ABC ones as well. Carbon dioxide and foam are not suitable; there is information suggesting that heptafluoropropane can produce hydrogen fluoride. I seek advice from those who are knowledgeable on this matter.
