2. Occupational Health and Safety - OHS
OHS is a planned system of working to prevent illness and injury
where you work by recognizing and identifying hazards and risks.
Hazard
Hazard is a situation in the workplace that has the potential to
harm the health and safety of people or to damage plant and
equipment anything that could hurt you or someone else.
Risk
Risk is the chance or probability that a person will be harmed or
experience an adverse health effect caused by a hazard.
3. Factors that influence the degree of risk
include
How much a person is exposed to a hazardous thing or condition
How the person is exposed e.g., breathing in a vapor, skin contact
How severe are the effects under the conditions of exposure
5. Three steps to manage health and safety at
work
SPOT THE HAZARD
(HAZARD
IDENTIFICATION)
ASSESS THE RISK
(RISK ASSESSMENT)
MAKE CHANGES
(RISK CONTROL)
7. Safety hazards
• These are the most common and will be present in most
workplaces at one time or another. They include unsafe
conditions that can cause injury, illness and death.
It includes
• Spills on floors or tripping hazards, such as blocked aisles or cords
running across the floor.
• Working from heights, including ladders, scaffolds, roofs, or any
raised work area.
• Unguarded machinery and moving machinery parts; guards removed
or moving parts that a worker can accidentally touch
8. Physical Hazards
• Are factors within the environment that can harm the body
without necessarily touching it.
It includes
• High exposure to sunlight/ultraviolet rays.
• Temperature extremes – hot and cold.
• Constant loud noise.
9. Mechanical Hazards
• Mechanical hazards are created as a result of either
powered or manual (human) use of tools, equipment or
machinery and plant.
It includes
• Impact - being hit by ejected parts of the machinery or equipment.
• Entrapment - being caught in a moving part of a machine or
equipment or plant.
• Shearing - can be two moving parts (sharp or otherwise) moving
across one another.
• Cutting - severing of a human body part by a cutting motion e.g.
amputation of finger on a cutting machine.
10. Electrical Hazards
• Dangerous situation where a worker could make electrical
contact with energized equipment or a conductor, and from
which the person may sustain an injury from shock.
It inlcudes
• Improper grounding
• Exposed electrical parts
• Inadequate wiring
• Damaged Circuits
• Wet Condition
• Damaged tools and equipments
11. Ergonomic hazards
• Occur when the type of work, body positions and working
conditions put strain on your body.
It Includes
• Improperly adjusted workstations and chairs.
• Frequent lifting and Poor posture.
• Awkward movements, especially if they are repetitive Repeating the
same movements over and over.
• Having to use too much force, especially if it is frequently.
• Vibration
12. Psychological hazards
• Hazards or stressors that cause stress (short-term effects)
and strain (long-term effects). These are the hazards
associated with workplace issues such as workload, lack of
control and or respect, etc.
It includes
• Workload demands.
• Workplace violence.
• Intensity and/or pace.
• Social support/relations.
• Sexual harassment.
13. 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.
It includes
• 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.
14. Biological hazards
• Associated with working with animals, people, or infectious
plant materials. Work in schools, day care facilities, colleges
and universities, hospitals, laboratories, emergency
response, nursing homes, outdoor occupations, etc. may
expose you to biological hazards.
It includes
• Blood and other body fluids.
• Fungi/mold and Bacteria and viruses.
• Insect bites.
15. Recycling
• While recycling is good for
the environment, it can be
dangerous for workers.
Certain materials that are
recycled or reused, such as
scrap metal, electronics,
batteries, and used oil and
other chemicals, have
materials that directly pose
hazards to workers.
• In addition to those
hazards, there are some
hazards that are common
across various types of
recycling, such as traffic
safety, moving machine
parts, unexpected machine
startup, lifting injuries, and
slips, trips, and falls.

17. Hazards in Recycling Industry
• Traffic Safety
• Loading
• Unloading
• Forklift
• Lead
• Machinery
• Unexpected Machine Start
• Crushing Hazards
• Fire explosions
• Electrical
• Combustible Dust
• Manual Handling
• Slips, trips and falls
18. Hazards found in Recycling Industry
Proper access is not
provided for the
equipment.
The operator is prone
to falling hazard.
27. Heat Stress - Furnaces
• Sweat evaporation is restricted by the type
of clothing and the humidity of the
environment
• Heat will be produced within the body due
to the work rate and, if insufficient heat is
lost, core body temperature will rise
• as core body temperature rises the body
reacts by increasing the amount of sweat
produced, which may lead to dehydration
• heart rate also increases which puts
additional strain on the body
• if the body is gaining more heat than it can
lose the deep body temperature will
continue to rise
• eventually it reaches a point when the body’s
control mechanism itself starts to fail
28. Forklifts - Accidents
• Unstable loads
• Loads of hazardous materials
• Carrying a heavy load with the forks too high
• Working around loading docks
• Carrying loads that block the forward vision
• Stacking and unstacking on racks
29. Forklift accident statistics
• Forklifts account for around 85 deaths every year.
• Forklift accidents that result in serious injury total 34,900 annually.
• Non-serious injuries related to forklift accidents reach 61,800 each
year.
• A forklift overturning is the most common incident, accounting for
24% of all forklift accidents.
30. Fatal Four
Out of 4,693 worker fatalities in private industry in calendar year 2016, 991 or 21.1% were in
construction — that is, one in five worker deaths last year were in construction. The leading causes
of private sector worker deaths (excluding highway collisions) in the construction industry were
falls, followed by struck by object, electrocution, and caught-in/between. These "Fatal Four" were
responsible for more than half (63.7%) the construction worker deaths in 2016, BLS reports.
Eliminating the Fatal Four would save 631 workers' lives in America every year.
• Falls — 384 out of 991 total deaths in construction in CY 2016 (38.7%)
• Struck by Object - 93 (9.4%)
• Electrocutions - 82 (8.3%)
• Caught-in/between* - 72 (7.3%)
• (*This category includes construction workers killed when caught-in or compressed by
equipment or objects, and struck, caught, or crushed in collapsing structure, equipment, or
material)
