What does the explosion-proof value of new energy batteries mean
Intrinsically Safe vs. Explosion Proof: What''s the Difference?
Meanwhile, explosion-proof means that if an explosion did happen, the device would be protected by an explosion-proof enclosure that helps contain explosions and prevent them from spreading. Therefore intrinsically safe refers to explosion prevention, whereas explosion-proof refers to containment .
