A chemical hazard is a type of
occupational hazard caused by
exposure to chemicals in the
workplace.
Exposure to chemicals in the
workplace can cause acute or long-
term detrimental health effects.

Route of Entry

Gases
Gases are formless fluids that expand to
occupy the space or enclosure in which they
are confined.
Examples are acetylene, nitrogen, helium,
and argon; and carbon monoxide generated
from the operation of internal combustion
engines or by its use as a reducing gas in a
heat-treating operation

particularly compressed air, steam, natural
gas and liquid petroleum gas (LPG).

Example of
confined
spaces
B. Confined Spaces
Confined space is a space that is
1.large enough and configured
so an employee can enter and
perform assigned work
2.has limited or restricted means
for entry or exit and
3.is not designed for continuous
employee occupancy.
19

Major Hazards Within Confined Spaces
•Oxygen-deficientatmosphere
•Purging agents such as
nitrogen and argon.
•Electricalshockhazards

Example of
Heavy Metals
in the
workplace
Heavy
Metals
Route of
Entry
Workers/industry
Exposed
Mercury Ingestion, skin
contact,
Fluorescent light bulb
(CFL) recycling facilities,
Chemical processing
plants.
Cadmium Inhalation,
ingestion, skin
contact
industries and
manufacturing of some
batteries and solar cells,
electroplating, and silver
soldering.

Dust and Particulate
Particulates include dusts, fibers, mists and fumes.
Nature of Exposure
Particulate matter enters the body through the nose
and mouth during breathing.
PM 10 (10 micrometers) are eliminated through
coughing, sneezing and swallowing
PM2.5 particles are able to invade deep into our
respiratory tract into the lungs and may be deposited
into the lungs due to small size and density.
Soluble components enter systemic circulation leading
to increase in systemic oxidative stress and
inflammation.

can cause acute and chronic
infections by entering the body
either directly or through
breaks in the skin.

II. Biological
Hazards
33
Bacteria
Bacteria are simple single-celled
organisms.

II.
Biological
Hazards
34
Viruses
Viruses are micro-organisms but are not
strictly alive.

Protozoa are a very large and diverse group
of single-celled organisms that all have a
cell nucleus.

Occupation
at Risk of
Exposure
•doctors, surgeons, nurses and
ancillary staff, such as hospital
porters.
•Dentist and laboratory staff.
•Farm workers, Vets, Zoo workers,
Pet shop workers and Sewage
workers.

III. Physical Health
Hazards
•Physical hazards include
excessive levels of ionizing
and nonionizing
electromagnetic radiation,
noise, vibration, illumination,
abnormal pressure and
temperature.

A. Radiation
Radiation is energy that is emitted by a
source.
Types of Radiation
•IONIZING RADIATION
•NON-IONISING RADIATION

Types of
Ionising
Radiation
•Alpha particles –They do not have much
penetrating power and are stopped by thin
material such as paper and the dead layer of
cells on the surface of the skin.
•Beta particles –They have more penetrating
power and can penetrate through the skin
into living tissues. Considered hazardous
when outside the body.
•X-rays –They have high penetrating power
and can pass right through the human body
(though not through dense bone tissue).
Considered very hazardous.

Types of
Ionising
Radiation
•Gamma-rays –They have very high
penetrating power and can pass right
through the human body (even the bones)
and through solid objects such as steel and
concrete to a degree. Considered very
hazardous.
•Neutrons-They have very high penetrating
power and can penetrate through the body.
Considered very hazardous.

Workers at
Risk of
Exposure to
Ionizing
Hazards
•Healthcare and veterinary workers.
•Caring for patients who have been
treated with Iodine-131 or other nuclear
medicine radioactive materials, Assisting
with fluoroscopy procedures.
•Certain industrial and laboratory workers
•Aircrew (flight attendants and pilots)

Types of
Non-Ionising
Radiation
41
Ultra-violet (UV)
Visible light
Infra-red (IR)
Microwaves
Radiowaves

Workers at
Risk of
Exposure to
Non-ionizing
Hazards
•Many workers are exposed to common
sources of nonionizing radiation at work
such as used of Microwave ovens,
computer screens, and cell phones.
•Some healthcare workers

B. Noise
Noise is measured in units of sound pressure
levels called decibels, named after Alexander
Graham Bell, using A-weighted sound levels
(dBA).
43

Occupations may
be at Risk from
Excessive Noise
Exposure
44
Entertainment-sector workers
Manufacturing-sector workers –exposed to industrial
machinery noise.
Call-centre staff –exposed to loud nose and acoustic
shock from the use of headset.
Traffic Enforcer
Street sweepers
Airport personnel (ground crew)

C. Vibration
Vibrationis the mechanical oscillations of an object
about an equilibrium point.
Vibration enters the body from the organ in contact
with vibrating equipment.
Hand-arm Vibration Whole Body Vibration

Occupation/Workers
at Risk
•Drivers of forklift trucks.
•Operators of heavy machines.
•Aircraft personnel.
•Estates workers –using powered lawnmowers
and brush cutters.
•Mechanics and body shop workers –using
powered tools such as orbital sanders and torque
wrenches.
•Drivers of heavy vehicles-tractors and earth-
moving vehicles.

D. Illumination
Defined as the intensity of light per unit
area.
Illumination level is the quantity of light
that illuminates a surface; measured in
foot candles or in lux.
Glare -as any brightness within the field
of vision that may cause discomfort,
annoyance, interference with vision, or
eye fatigue.

sunlight (outdoor).
poor lightning areas/site.
Entertainer (nightclub).
Security guard (nightshift).

E. Temperature
and Humidity
50
Heat stress may be experienced by
workers exposed to excessive heat
arising from work.
Workers at risk of heat stress include
outdoor workers and workers in hot
environments such as firefighters,
bakery workers, farmers,
construction workers, miners, boiler
room workers, factory workers.

E. Temperature and
Humidity
•Cold stress occurs by driving down the skin
temperature, and eventually the internal body
temperature.
Workers at risk
•Outdoor work (agriculture, maintenance), Sea fishing,
shipping, Oil rigs, Deep freeze stores, cold rooms &
Diving (diver).
51

IV.
Ergonomics
•The science of ergonomics studies and
evaluates a full range of tasks including, but
not limited to, lifting, holding, pushing, and
reaching.
Ergonomics & Risk Factors
•Risk factors inherent in the worker
•Risk factors inherent in the task
•Risk factors inherent in the environment

Who is at
risk?
•repeat the same motion often throughout
their workday.
•do their work in an awkward position.
•use a great deal of force to perform their
jobs.
•repeatedly lift heavy objects.
•face a combination of these risk factors.

Psychosocial hazards
•Formed when pressures in the workplace combine with problems in an
employee’s private life, threatening the employee’s ability to meet his or
her needs, psychosocial hazards develop.
•The hazards may be manifested in a variety of ways, including physical,
mental and emotional issues, and they can spill over into the potential for
physical harm.
•Work Culture
•Leadership
•Working Conditions
•Labor Relations
•Bullying

Summary
•Industrial hygiene is the science of protecting
and enhancing the health and safety of
people at work and in their communities.
•Those dedicated to anticipating, recognizing,
evaluating and controlling those hazards are
known as Industrial Hygienists .
•Safety Officer primary duties is to conduct
health hazards identification in the
workplace.
•Health hazards in the workplace are
classified into chemical, biological, physical
and ergonomics.
•SDS provide information on the hazardous
substances.

Conclusion
•Industrial hygienists are trained to
anticipate, recognize, evaluate, and
recommend controls for environmental
and physical hazards that can affect the
health and well-being of workers.
