VIBRATION SAFE WORK PRACTICE (SWP) TOOL VIBRATION SWP ID#: 10-001 Version 1 Abstract Category Occupational Health An object “vibrates” when it moves back and forth, up and down, or side Issue Date: to side, usually very rapidly. “Vibration” describes the physical energy 2019-01-01 (yyyy-mm-dd) from a vibrating object, and also what we feel when that energy is Last Review Date: transmitted to us. 2020-01-01 (yyyy-mm-dd)

Hazards: Disorders: permanent injuries to blood vessels (vascular), nerves (neurological) and joints (musculoskeletal) can be caused by repeated vibrations from hand and power called hand-arm vibration syndrome.

DO Do NOT • Use gloves to keep hands warm and also provide some • Use a tool that under normal conditions should not protection from vibration vibrate. Check for damage or out of calibration. • Limit the time a worker is exposed to the vibration. Short • Use blunt or damaged tools and replace worn out items bursts are acceptable. such as grinding wheels. • Improve the ergonomic design of workstations. • Work in awkward postures that can increase the load on • Attempt to do job without using vibration tools, where employees’ hands, wrists, and arms possible • Use vibrating tools and equipment for long periods, • Move and massage fingers during breaks especially in the cold • Hold vibrating tools tightly • Ignore signs and symptoms of tingling & numbness. See • Keep equipment in good condition your doctor. • Report poorly functioning tools to supervisor • Buy tools with low or reduced vibration

General Safe Work Practices

1. Use a non-vibrating alternative method to complete the work, if possible. 2. Take regular breaks 3. Alternate vibrating work with non-vibrating work 4. Rotate vibrating work with co-workers 5. Use tools in ways that minimize vibration exposure 6. Maintain tools properly – inadequate maintenance can cause parts to become loose, misaligned, worn and unbalanced. 7. Maintain a proper grip. Excessive hand grip force increases ligament and tendon tension and reduces local blood circulation worsening the effects of vibration exposure. BASS 8. Hold tools using a “power grip” - whereby the fingers are wrapped around the object and the thumb is placed against it – like

making a fist. INSTALLATION
