Keep your team well-protected during every step of the metalworking process. Whether your crew is grinding, finishing or sanding, being aware of the risks at each point in the job is key to mitigating them.
Hand-arm vibration syndrome (HAVS) is one of the risks of using abrasives. HAVS refers to a collection of musculoskeletal conditions, like vibration white finger and carpal tunnel syndrome, caused by the vibration of abrasive tools. From tingling and white fingers to red fingertips, aching hands or fingers and loss of strength and dexterity, the symptoms and conditions become more severe and irreversible over time.
Effective ways to prevent HAVS injuries.
A recent study conducted by 3M found that 86% of respondents did not report HAVS as a “key concern,”. Yet 72,000 to 144,000 HAVS cases are reported in Canada each year.1 While Canada’s occupational safety and health standards don’t specify limits to vibration exposure, there are simple and effective ways to prevent HAVS injuries for your team.
HAVS injury prevention starts with selecting the right tools and abrasives. In independent testing, 3M abrasives containing precision-shaped grain technology were proven to significantly reduce HAVS injury risks like operator fatigue and vibration exposure. Here are some tips for choosing the right products to reduce HAVS injuries:
- Select an abrasive that grinds faster. 3M™ Cubitron™ II Abrasives require less trigger time, and therefore less pressure is required from the operator. Products like 3M™ Cubitron™ II Fibre Discs 982C have shown to reduce vibration exposure by up to 91%.3
- Choose an abrasive designed to vibrate less. 3M™ Cubitron™ II Depressed Centre Grinding Wheels have been proven to reduce vibration by up to 64%. 3M™ Cubitron™ II Cut-Off Wheels, Scotch-Brite™ Bristle Discs and Brushes, and 3M™ Cubitron™ II Clean Sanding Abrasive Disc are also designed to reduce vibration exposure.4
Beyond the products you choose, working conditions and how your workers’ grip and handle their equipment contribute to the HAVS injury risk level. Here are some things you can do:
- Look for opportunities to eliminate, modify or even mechanize tasks that involve high levels of vibration or that demand bending wrists in excess. You can also try having your team alternate between vibrating and non-vibrating tasks.
- Ensure the working environment is not too cold, as cold environments can further impair blood circulation.
- Use vibration sensors and tool timers to measure and monitor vibration exposure and reduce the impact of tool vibration.
