40. Vibration / 41. Wellness Programs / 42. Workplace Violence Flashcards
Vibration risk factor
- Individual health
- Intensity and frequency
- Duration
- Affected areas
Two principal types of vibration
HAVS: Hand-Arm Vibration Syndrome
Whole Body Vibration
Tools intensify HAVS by (5)
- Heightened speed of vibration
- Poor maintenance
- Tool weight
- Lack of handle insulation
- Increased skin contact
Workers intensify HAVS by: (4)

- Awkward postures
- Incorrect tool usage
- Prior injuries or poor health
HAVS chronic effects: (4)
- Damage to muscles, tendons, bones & joins
- Nervous system problems
- Raynauld’s syndrome (“white/dead finger” in cold env.)
- Disrupted circulation to the hands and arms
Control measures to HAVS
Substitution processes and methods
Isolation
Cushioning methods
Low vibration and acceleration
Maintenance
Training
Are recommendable anti-vibration gloves to prevent HAVS?
No, since they are thicker and this cause that the worker uses greater strength to grip the tool.
Main sources of Whole Body Vibration

- Road & surface conditions
- Machine & vehicle design
- Vibration of the floor
Risks of WBV exposure include:
