Q

What happens during a BLEVE?

A

IN A NUTSHELL: if a fire/extreme heat is applied to a container holding liquid, the liquid will turn to gas and the pressure will build until the container explodes.

48
Q

What is a Division 5.1 hazard?

A

They are OXIDIZERS, which support combustion and intensify fires by yielding oxygen.

49
Q

50
Q

What is an Organic Peroxide?
