​​​Fire and explosive hazards include combustible and flammable liquids and substances, and/or when hot work is performed. Fire and explosion can occur when the temperature has reached the flash point of the volatile material, and where there is sufficient vapour present in the atmosphere.

What is the effect of fire and explosion?

The effects of accidental fires or explosions can be devastating in terms of lives lost, injuries, damage to property and the environment, and to business continuity. Working with flammable liquids, dusts, gases and solids is hazardous because of the risk of fire and explosion.

What reaction causes explosions?

One more important section related to combustion is the "explosive" chemical. Explosives are substances that undergo a rapid oxidation reaction with the production of large quantities of gases. It is the sudden buildup of gas pressure (see products above) that constitutes the nature of an explosion.
