Workplace
Hazards
1. Safety Hazards
oSafety Hazards are unsafe working conditions that
that can cause injury, illness and death. Safety
hazards are the most common workplace hazards.
1. Safety Hazards
oThey include:
• Anything that can cause spills or tripping such as cords
running across the floor or ice
• Unguarded machinery and moving machinery parts
that a worker can accidentally touch
• Electrical hazards like frayed cords, missing ground
pins, improper wiring
• Confined spaces

Slips and
falls
Fire
2. Biological Hazards
oAlso known as biohazards, refer to biological
substances that pose a threat to the health of living
organisms, primarily that of humans such as
viruses, bacteria, fungi and parasites.
3. Chemical hazards
oAre 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.
oBeware of:
• Liquids like cleaning products, paints, acids and solvents
– especially if chemicals are in an unlabeled container!
• Gases like acetylene, propane, carbon monoxide and
helium
• Flammable materials like gasoline, solvents, and
explosive chemicals
• Pesticides
4. Physical hazards
oPhysical hazards can be any factors within the
environment that can harm the body without
necessarily touching it.
oThey 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
5. Ergonomic hazards
oOccur 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.
oErgonomic 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
Proper lifting
6. Psychological and Work
organization Hazards
oThose that are basically causing stress to a worker.
This kind of hazard troubles an individual very
much to an extent that his general well- being is
affected
oExamples include:
• Workload demands
• Workplace violence
• Personal problems
• Respect (or lack thereof)
• Flexibility
• Control or say about things
• Social support or relations
• Illness
