HAVS

Workers who use vibrating tools on a daily basis are at an increased risk of suffering from HAVS (Hand-Arm Vibration Syndrome). Tools such as jackhammers, chisels, chainsaws, sanders, grinders, riveters, breakers, drills, and compactors are often associated with these sorts of injuries. Over long periods of time, repeated exposure to these vibrations can cause physical damage to the hands and arms.

What are the symptoms of HAVS?

• bluish discoloration of the skin (cyanosis)
• whitening of fingertips after cold or damp exposure (known as Raynaud’s phenomenon)
• numbness, with or without tingling
• hand sensitivity and sense of touch reduced
• decreased grip strength

How can I prevent HAVS from occurring?

• wear proper-fitting protective equipment (anti-vibration gloves)
• take advantage of job rotation and exercises that will maintain blood circulation
• keep your hands warm and dry
• avoid unnecessary vibration exposure with proper tool handling
• be aware of safe vibration levels, report any poorly working tools
• ensure tools are properly maintained (handles insulated, etc.)
• report any tingling, numbness or finger-whitening symptoms immediately
