What is an explosive hazard?
The OSHA Laboratory Standard defines an explosive as a chemical that causes a sudden, almost instantaneous release of pressure, gas, and heat when subjected to sudden shock, pressure, or high temperature. Under the Department of Transportation (DOT) hazard class system, explosives are listed as hazard class 1.
What are hazmat signs?
These signs have oxygen written on them and a graphic of an “O” with flames. White indicates poisonous and biohazardous substances like dyes, acids, aerosols and medical waste.

What are the example of explosive?
TNT and dynamite are known examples of explosive substances. Pyrotechnic substances: a substance (or a mixture of substances) designed to produce an effect by heat, light, sound, gas or smoke (or a combination of them) as a result of non-detonative self-sustaining exothermic chemical reactions.
What products have explosive symbols?

What does the flammable hazard symbol mean?
Flammable (Symbol: open flame) This symbol refers to any flammable chemicals or other substances that ignite on contact with air, a small ignition source, has a low flash point or can evolve highly flammable gases when in contact with water. The symbol is a large open flame.
What are the types of explosions?
There are three main types of explosions: chemical, mechanical and nuclear.
What does the explosive sign mean?

What are the dangers of explosives?
mine-induced seismicity: this is very dangerous in underground mining areas and can be triggered by the use of explosives, resulting in earthquake-like events that can collapse the mine, flood it or even cause damage on the surface. With all the risks involved, a thorough, comprehensive safety training plan is vital.
