1

The 4 elements of industrial hygiene are: anticipation, recognition, evaluation, and control.

Describe anticipation & recognition.

1. Anticipation: identify potential hazards before they're introduced

2. Recognition: identify potential hazard that a chemical, physical, biological, or ergonomic situation poses to health

2

What are some examples of workplace hazards in the following classes?

Chemical?
Physical?
Noise
Temperature
Environmental
Biological

Chemical: gases, vapors, dusts, smoke

Physical: radiation, vibration, pressures

Noise

Temperature: health and cold stress

Environmental: ergonomic hazards such as repetitive motion

Biological: insects, mold, yeast, fungi, bacteria, viruses

3

What are the employers responsibilities under a Hazard Communication Program? (5)

1. written program
2. identify/communicate all chemical hazards
3. MSDS for each chemical
4. proper labeling
5. worker training

4

What information must be provided in an MSDS? (5)

1. physical hazards
2. health hazards
3. routes of exposure
4. precautions for safe handling
5. emergency & first aid procedures

5

PEL? TWA?

PEL: permissible exposure limit
-OSHA regulation, legally enforceable

TWA: time weighted average
-avg exposure over 8hr/day and 40hr/week

6

Ceiling? STEL?

Ceiling: absolute maximum exposure level not to be exceeded

STEL: short term exposure limit; max exposure in a 15 minute period
(from ACGIH)

7

How do PEL values compare to community exposure reference values (eg, RfD, cancer risk thresholds)?

Community exposure refrences deals only with direct hazard contact and doesn't include physical hazards such as noise.

8

The 4 elements of industrial hygiene are: anticipation, recognition, evaluation, and control.

Describe evaluation & control.

Evaluation: evaluate extent of exposure to hazards for employees

Control: control exposure to hazards via engineering, procedural, or other means
