4、 Precautions

Benzene is a flammable and explosive organic substance, which is prone to explosion and fire in case of open fire. When benzene burns, it emits strong black smoke with pungent smell. Because benzene vapor is heavier than air, the flame will burn along the ground. Benzene leaks and has pungent smell, so pay attention to protection.
