7. Concept & Definition OCCUPATIONAL HYGIENE
Anticipation, recognition, evaluation and control of hazards in the working environment with the objective of protecting worker health and well-being and safeguarding the community at large

8. Occupational hygiene is considered a "science"; but it is also an art that involves judgment, creativity and human interaction.

9. Occupational Hygienist (OH)
Scientists and engineers committed to protecting the health and safety of people in the workplace and the community
Traditionally occupational hygienists worked primarily in factories and other industrial settings
Today, Occupational hygienists can be found in almost every type of work setting

10. Goal of the occupational hygienist
Keep workers, their families, and the community healthy and safe.
Play a vital part in ensuring OHS laws and regulations are followed in the work environment

11. Typical roles of the OH
Investigating and examining the workplace for hazards and potential dangers
Making recommendations on improving the safety of workers and the surrounding community
Conducting scientific research to provide data on possible harmful conditions in the workplace
Developing techniques to anticipate and control potentially dangerous situations in the workplace and the community

12. Cont…… Training and educating the community about job-related risks
Advising government officials and participating in the development of regulations to ensure the health and safety of workers and their families
Ensuring that workers are properly following health and safety procedures

13. What do OH do? Anticipation Recognise hazards/sources
Evaluate exposure/risk
Design, evaluate effectiveness of control strategies

14. Anticipation Vital skill Require access to readily available sources;
MSDS
Literatures
Past experiences
Online database

15. Recognise hazards/sources
Records of accidents and diseases
Raw materials, products, by-product
Design of process, equipment, environment
Process and operations
Walkthrough survery – senses, talk to workers, etc
Grab samples (air, dust, gas, water, soil etc)
Measure noise levels etc..

16. Evaluate exposure/risk
Purpose
exposure evaluation and assessing risks associated with the hazards
A typical risk assessment include,
Identify the health effects & route of entry
Estimate likelihood of exposure by :
Monitoring the exposure to the hazard (e.g. substance/noise/dust)
Comparing with recommended exposure standard or limits
Deciding whether there is a risk to health & safety
Some may not need instrument but some require specific instruments
Standard, regulations e.g. personal exposure,

17. Specific Instruments Noise level – Dosimeter, SLM Lighting – Luxmeter
Heat – WBGT, Psychrometer
Gas/Vapour/Fumes – Gas detector, Drager pump
Dust – suction pump

18. Evaluate Controls Principle of control measures
Hierarchy of control measures
