LEARNING OUTCOME 1
Identify hazards and risks
PERFORMANCE STANDARDS
· Workplace hazards and risks are identified and clearly explained.
· Hazards/risks and its corresponding indicators are identified in with the company procedures.
· Contingency measures are recognized and established in accordance with
A hazard is something that can cause harm, eg electricity, chemicals, working up a ladder,
noise, a keyboard, a bully at work, stress.
Risk is the chance or probability that a person will be harmed or experience an adverse
health effect once to a hazard. It may also apply to situations with property or equipment
loss.
A risk is the chance, high or low, that any hazard will actually cause somebody harm.
For example, working alone away from your office can be a hazard. The risk of personal
danger may be high. Electrical repair is a hazard. If someone accidentally turnedon the
power the worker’s life will be in a 'high-risk' category.
There are five major types of hazards which can put both your health and your safety at
risk.
1. Chemical hazards
2. Physical hazards
3. Biological hazards
4. Ergonomic hazards or job related hazards
5. Psychological hazards or stress
CHEMICAL HAZARD
If you are working with cleaning products, bleaches, paints, and other chemical agents, you
need to understand what a chemical hazard is as well as how to protect yourself.
PHYSICAL HAZARDS
BIOLOGICAL HAZARDS
Why be careful around ticks, mouse droppings, bird poop and wild animals? Because you
might get sick from working around certain animals, including people. Biological hazards
include bacteria, viruses, insects, plants, birds, animals, and humans. The risks run from
skin irritation and allergies to infections.
ERGONOMIC HAZARDS
If your job is poorly designed, you can develop long term health problems. These problems
can arise from simple things, like working for long periods in an awkward position or having
to make the same motions over and over again.
PSYCHOLOGICAL HAZARDS
Those 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 Stress can lead to
long-term health problems. Headaches, anxiety, and impatience are early signs of stress.

• heavy workloads
• lack of control over the pace of work
• shift work
• noise
• working by yourself
• fear of job-loss
• conflict with the employer
One of the most critical among the hazards that one may encounter is the chemical hazard. Chemical
may produce reactions that may endanger ones health and life. This is the reason why the American
Conference of Governmental Hygienist (ACGIH) established a threshold limit value (tlv). TLV is the term
used by the American Conference of Governmental Hygienists (ACGIH*) to express the airborne
concentration of a material to which nearly all persons can be exposed day after day, without adverse
health effects
LEARNING OUTCOME 2
Evaluate hazards and risks
The goal of all occupational safety and health programs is to foster a safe work
environment. As a secondary effect, it may also protect co-workers, family members,
employers, customers, suppliers, nearby communities, and other members of the public
who are impacted by the workplace environment. It may involve interactions among many
subject areas, including occupational medicine, occupational (or industrial) hygiene, public
health, safety engineering / industrial engineering, chemistry, health physics.
Risks include acute and chronic health effects, for example, irritation or cancer, and
physical effects such as fires or explosions. The hazards are physical and health hazards.
II. Risk assessment
Fire is one type of hazard that needs careful evaluation before extinguishing it. Not all fire
could be extinguished by water that is why it is necessary that we knew first the cause of
fire before dealing the fire.
1. Flash Point and Method Used: Lowest temperature at which a liquid will give off enough
flammable vapors to ignite. Since flash points vary according to how they are obtained, the
method used must be listed. Chemicals with lower flash points present a greater
flammability hazard.
2. Flammable Limits: Range of concentrations over which a flammable vapor mixed with air
will flash or explode if an ignition source is present. Range extends between lower explosive
limit (LEL) and upper explosive limit (UEL) and is expressed in percentage of volume of
vapor or gas in air (0 – 100%). Chemicals with a broad flammable range (i.e., range
between the LEL and the UEL) and/or a flammable range in the lower percentages, present
a greater flammability hazard.
3. Extinguishing Media: Fire-fighting material for use on substance that is burning,
Firefighting material should be indicated by its generic name (e.g. water, foam, dry
chemical, etc.).
III.
Waste management is the collection, transport, processing or disposal, managing and
monitoring of waste materials. The term usually relates to materials produced by human
activity, and the process is generally undertaken to reduce their effect on health, the
environment or aesthetics.
Waste management practices differ for developed and developing nations, for urban and
rural areas, and for residential and industrial producers. Management for nonhazardous
waste residential and institutional waste in metropolitan areas is usually the responsibility of
local government authorities, while management for non-hazardous commercial and
industrial waste is usually the responsibility of the generator.
PHILIPPINE CLEAN AIR ACT OF 1999 (Refer to Appendix 1 for elaboration)
The Philippine Clean Air Act of 1999 under its ―Declaration of Principles” stated that the

LEARNING OUTCOME 3
Personal hygiene
Finally, personal hygiene (cleanliness) is also very important as a method of controlling
hazards. Your employer should provide facilities so you can wash and/or take a shower
every day at the end of your shift, no matter what your job is. Wash your skin and hair with a
mild soap, rinse and dry your skin completely to protect it. Washing hands regularly, and
eating and smoking away from your work area help to prevent ingesting contaminants.
Lack of personal cleanliness can affect your family's health. Your family can be exposed to
hazards you work with if you bring chemicals and other workplace contaminants home with
you on your clothes, hair or skin. Before you leave work, wash/shower and change your
clothes when necessary to prevent bringing workplace contaminants home.
Leave your dirty clothes at work or, if you must wash them at home, wash them separately —
not with the family wash.
It may seem that the amount of contaminant you can bring home on your clothes or skin is
very small and cannot hurt your family. In reality a small exposure every day for months can
add up to a big exposure. A classic example of this ―spreading the hazard‖ involves
asbestos, where wives of asbestos workers have developed asbestosis from exposure to
the asbestos on their husbands' work clothes. Similarly, children have developed lead
poisoning from exposure to lead which comes home on their parents' work clothes. If you
wear protective clothing at work, such as aprons, laboratory coats, overalls, etc., these
should be cleaned regularly and you should inspect them for holes or areas that are worn
out. Workers who launder these clothes should be trained in the types of hazards they may
work with and how they can be controlled. Inspect your underclothes at home for any signs
of contamination with oils, solvents, etc. If you find any signs, then it means your protective
clothing at work is not effective.
EMERGENCY PREPAREDNESS
Process of ensuring that an organization has complied with the preventive measures, is in a
state of readiness to contain the effects of a forecasted disastrous event to minimize loss of
life, injury, and damage to property, can provide rescue, relief, rehabilitation, and other
services in the aftermath of the disaster, and has the capability and resources to continue to
sustain its essential functions without being overwhelmed by the demand placed on them.
Preparedness for the first and immediate response is called emergency preparedness.
Always remember that disaster comes in the most unexpected time and place. Being ready
is always a necessity in all circumstances. The government is giving trainings that
everybody needs in all our localities. One should participate in this disaster training so
that we will not be caught unaware when calamity struck.
