Vibration Measurement and Actions
The vibration directive places the responsibility for compliance on employers.
Actions that should be followed by employers include:
¾ Assess the levels of vibration exposure.
¾ Determine from this assessment if operators will be exposed to vibration
levels above the limits stated in the directive.
¾ Take appropriate actions to reduce operator’s exposure to vibration.
¾ Provide operators with information and training to reduce their exposure to
vibration.
¾ Keep good records and update operations and training on a regular basis.
If the assessment concludes that vibration level exposure is too high, one or more
of the following actions may be necessary:
1. Train operators
¾ Perform operations (accelerating, steering, braking, etc.) in a smooth
manner.

holes.
2. Choose proper equipment for the job

¾ Ensure good visibility from the operator’s position.
3. Maintain the work site
