Chemicals that can cause harm if ingested, inhaled, or absorbed through the skin.
Toxic
Chemical Hazards
- Toxic
- Corrosive
- Flammable
- Explosive
Chemicals that can cause damage to skin or tissue.
Corrosive
Chemicals that can explode under
certain conditions
Explosive
Chemicals that can easily catch fire.
Flammable
Physical Hazards
- Electrical Hazard (shock, electrocuted)
- Mechanical Hazard (grinding)
- Thermal Hazard (fume hood, furnace)
- Radiation Hazard
- Fire Hazard
Biological Hazards
- Infectious agents
- Toxins
- Allergens
Organisms that can cause disease, such as bacteria, viruses, or fungi.
Infectious agents
Substances produced by living organisms that can cause harm if ingested, inhaled, or absorbed through the skin.
Toxins
The amount of a chemical that is absorbed by and dispersed
throughout an organism is known as its
bioavailability
Substances that can cause an allergic reaction in some people.
Allergens
The cumulative effect of an agent’s uptake, transformation, and
removal by an organism as a result of all routes of exposure is known
as
bioaccumulation
Intake, modification, and removal of a material by an organism as a
result of exposure to aquatic contaminants result in
bioconcentration
What is the purpose of a fire
extinguisher?

Foam extinguishers
Used to extinguish Class C fires, which are fires involving electrical equipment.
Dry chemical extinguishers
Used to extinguish Class D fires, which are fires involving combustible metals.
Carbon dioxide extinguishers
It is the design of chemical products and processes that reduce or eliminate the use or generation of
hazardous substances.
