Workplace Safety Flashcards
The 4 elements of industrial hygiene are: anticipation, recognition, evaluation, and control.
Describe anticipation & recognition.
- Anticipation: identify potential hazards before they’re introduced
- Recognition: identify potential hazard that a chemical, physical, biological, or ergonomic situation poses to health
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
What are the employers responsibilities under a Hazard Communication Program? (5)
- written program
- identify/communicate all chemical hazards
- MSDS for each chemical
- proper labeling
- worker training
What information must be provided in an MSDS? (5)
- physical hazards
- health hazards
- routes of exposure
- precautions for safe handling
- emergency & first aid procedures
PEL? TWA?
PEL: permissible exposure limit
-OSHA regulation, legally enforceable
TWA: time weighted average
-avg exposure over 8hr/day and 40hr/week
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
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.
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
