Hazards in Working Environment


Biological Hazards:

Biological Hazards include exposure to harm or disease associated with working with animals, people, or infectious plant materials. Workplaces with these kinds of hazards include, but are not limited to, work in schools, day care facilities, colleges and universities, hospitals, laboratories, emergency response, nursing homes, or various outdoor occupations.


Types of things you may be exposed to include:

  • Blood and other body fluids

  • Fungi/mold

  • Bacteria and viruses

  • Plants

  • Insect bites

  • Animal and bird droppings


Physical Hazards:

Physical hazards can be any factors within the environment that can harm the body without necessarily touching it.


They include:

  • Radiation: including ionizing, non-ionizing (EMF’s, microwaves, radiowaves, etc.)

  • High exposure to sunlight / ultraviolet rays

  • Temperature extremes – hot and cold

  • Constant loud noise

Ergonomic Hazards:

Occur when the type of work, body positions and working conditions put a strain on your body.  They are the hardest to spot since you don’t always immediately notice the strain on your body or the harm that these hazards pose.  Short-term exposure may result in “sore muscles” the next day or in the days following the exposure, but long term exposure can result in serious long-term illness.


Ergonomic Hazards include:

  • Improperly adjusted workstations and chairs

  • Frequent lifting

  • Poor posture

  • Awkward movements, especially if they are repetitive

  • Having to use too much force, especially if you have to do it frequently

  • Vibration

Chemical Hazards:

Are present when a worker is exposed to any chemical preparation in the workplace in any form (solid, liquid or gas).  Some are safer than others, but to some workers who are more sensitive to chemicals, even common solutions can cause illness, skin irritation, or breathing problems.


Beware of:

  • Liquids like cleaning products, paints, acids,solvents – ESPECIALLY if chemicals are in an unlabeled container !

  • Vapors and fumes that come from welding or exposure to solvents

  • Gases like acetylene, propane, carbon monoxide and helium

  • Flammable materials like gasoline, solvents, and explosive chemicals

  • Pesticides
