Industrial Hygiene

Main discipline of OSH:

Medicine- Toxicology- Industrial Hygiene- Safety- Epidermiology

Definition Industrial Hygiene: An art and science devoted to Anticipation, Recognition, Evaluation, and Control in work place by preventing it from Hazard (physical, chemical, ergonomic, biological etc).

Function Industrial Hygienist: POWER in OSH

(MP BANK): Money, Personality, Barrier, Authority, Network, Knowledge

Concept of Monitoring:

(Cx.A.R.E)- Anticipation, Recognition, Evaluation, Control

Anticipation: LITERATURE

Recognition: DATA (Medical chart, Safety Data Sheet, Work Environment Measure)

Evaluation: From (ORIGinalS^)- Observation, Report/Record, Interview, General Meeting, Surveillance/Sampling

Control Hierarchy in Industrial Hygiene:

(BAD ENSUEL)- Elimination, Substitution, Engineering, Administration, Behavioral

Surveillance- Environmental (M)-> Biological (M) -> Health (S)

Sampling-

• Smell- Air Sampling Train, Detector tube

• Vision- Photo-detector Cell

• Sound- Integrated Sound Level Meter

• Temperature- Heat Stress Monitor, Thermoanemometer

• Biological- Chemical itself Vs Metabolites

Threshold Limit Value (TLV): -Worker can expose everyday without adverse

Time-Weighted Average (TWA)- eg: 8H/day or 40H/weeks)

Short Term Exposure Limit (STEL)- eg: 15min/4times/60 min apart or fIT

Ceiling (C)- absolute exposure limit during exposure.
