1. DEFINITIONS
EPCT 2331 – Industrial hygiene Applications

2. What is
Industrial
Hygiene?
■ Science and art devoted to the
anticipation, recognition, evaluation, and
control of those workplace
environmental factors which may cause
sickness, impaired health and well-being,
or significant discomfort and inefficiency
among workers or among citizens of the
community.

3. What is an Industrial Hygienist?
■ A person who by study, training, and experience can:
 Anticipate;
 Recognize;
 Evaluate; and
 Control
Workplace environmental hazards.

4. Occupational Hazards (Some – not all)
■ Chemical Agents
– Gases, vapors, and particulate aerosols
■ Physical (energy) Agents
– Noise, ionizing/non-ionizing radiation, heat and cold stress
■ Biological Agents
– Infectious agents, allergens
■ Psychological stressors
■ Ergonomic stressors

5. Industrial Hygiene Concepts
■ Anticipation / Recognition of potential or actual hazards
through knowledge of:
– Materials
– Operations
– Processes
– Conditions
■ Scope of IH activities encompasses the “cradle-to-grave”
concept. (Yes, I am referring to hazardous waste
disposal.)

6. Industrial Hygiene Concepts
■ Evaluation of environmental factors through:
– Measurement of exposure intensity
– Determination of exposure frequency, and duration
– Comparison with regulatory, professional, and internal
standards
– Judgement: weigh all factors.

7. Control of Exposures
■ Employe methods to eliminate or reduce exposure resulting in elimination or
reduction of the occurrences of occupational disease through:
– Engineering (including process) interventions
– Administrative/programmatic measures
– Personal protective equipment

8. OPPORTUNITIES
FOR CONTROL
