Hazard
A hazard is something that can be dangerous to people, goods, and the environment.[1] Hazards are often marked with warning signs to help people know that a dangerous thing exists and to do the right thing to stay safe. Each hazard has ways to make it less dangerous or remove it.
For example, a motorist should read road signs and react to hazards on the road to stay safe like slowing down for sharp turns.
By Physical Nature
[change | change source]- Biological hazards are caused by living microorganisms (e.g., bacteria, viruses, and parasites) that can make other living things sick.[2]
- Chemical hazards are caused by harmful chemicals (e.g., acids).[3]
- Radioactive hazards are caused by materials that give off ionizing radiation (e.g., plutonium).
- Thermal hazards are caused by extreme heat (e.g., fires) or extreme cold (e.g., freezing weather).
- Kinetic hazards are caused by moving objects or forces (e.g., vehicles and loud vibrations).[4]
