1. Industrial Hygiene
Answer: Science and art devoted to the anticipation, recognition,
evaluation, prevention, and control of those environmental
factors or stresses arising in or from the workplace which may
cause sickness, impaired health and well being, or significant
discomfort among workers or among citizens of the community.
2. Occupational Health and Safety
Answer: Same definition as "industrial hygiene"; Science and art
devoted to the anticipation, recognition, evaluation, prevention,
and control of those environmental factors or stresses arising in
or from the workplace which may cause sickness, impaired
health and well being, or significant discomfort among workers
or among citizens of the community.
3. Principles of health and safety hazard identification rely on these 3
basic criteria
Answer: Recognition - of a hazard or potential hazard;
Assessment - and evaluation of the hazard; Controls - that are
implemented to minimize hazard
4. Hazard
Answer: Any source or situation with a potential for harm in
terms of a human injury or ill health, damage to property,
, damage to the workplace environment, or any combination of
these.
5. Risk
Answer: It is the chance or probability that a person will be
harmed or experience an adverse health effect if exposed to a
hazard. May also apply to situations with property or equipment
loss.
6. What is the purpose of a hazard/risk assessment?
Answer: To identify hazards and risks in the workplace so that
workers are made aware of unsafe conditions at a worksite.
7. Occupational Illness
Answer: A health problem caused by exposure to health hazards
in workplace
8. Occupational injury
Answer: Injury that results from a work-related accident or
exposure involving a single incident in the work environment.
9. Hazard-Contributing Factors:
Answer: People, Equipment, Materials, Environment, Process
10. Kinds of Hazards:
Answer: Machine, Energy, Confined Space, Material Handling,
Work practice/Ergonomic, Chemical/Biological
11. Aim of hazard/risk assessment process is to
Answer: Remove a hazard or reduce the level of risk by adding
precautions or control measures as necessary.
, 12. Levels of Risk involved with Hazard
Answer: Very Low, Low, Medium, High, Very High
13. Hazard Level: Very Low
Answer: Considered acceptable
14. Hazard Level: Low
Answer: No controls required unless can be implemented at low
cost
15. Hazard Level: Medium
Answer: Consideration should be whether the risks can be
lowered, where applicable, to a tolerable level and preferably to
an acceptable level, but the cost of additional risk reduction
measures should be taken into account
16. Hazard Level: High
Answer: Substantial efforts should be made to reduce the risk.
Risk reduction measures should be implemented urgently within
a defined period of time and it might be necessary to consider
suspending or restricting the activity, or to apply interim risk
control measures, until this has been completed. Arrangements
should be made to ensure that controls are maintained,
particularly if the risk levels are associated with extremely
harmful consequences
17. Hazard Level: Very High
Answer: These risks are considered unacceptable. Substantial
improvements in risk control measures are necessary so that the
risk is reduced to a tolerable and acceptable level. The work
activity should be halted until risk controls are implemented that
