Hazards that may be encountered in a research/experimental environment
fall into three categories:
Biological
A biological hazard is any viable infectious agent that present
a potential risk to the well-being of humans. Special training
is required for anyone working with blood, blood products, or
infectious agents.
Chemical
A chemical is considered hazardous if it has flammable, corrosive,
reactive, explosive, or toxic properties. Examples are solvents,
acids, and carcinogens.
Physical
Examples of physical hazards are ionizing radiation,
high-voltage electricity, laser beams, noise and earthquakes.
