Hand-arm vibration comes from the use of hand-held power tools and is the cause of significant ill health (painful and disabling disorders of the blood vessels, nerves and joints).
HAVS is preventable, but once the damage is done it is permanent.
HAVS is serious and disabling, and nearly 2 million people are at risk.
Damage from HAVS can include the inability to do fine work and cold can trigger painful finger blanching attacks.
By law, an employer must assess and identify measures to eliminate or reduce risks from exposure to hand-arm vibration so that employees are protected from risks to their health.
Where the risks are low, the actions you take may be simple and inexpensive, but where the risks are high, you should manage them using a prioritised action plan to control exposure to hand-arm vibration.
Where required, ensure that:
Control measures to reduce vibration are properly applied; and
You provide information, training and health surveillance.
Review what you are doing if anything changes that may affect exposures to vibration where you work.
This will depend on whether your employees regularly and frequently work with vibrating tools and equipment and/or handle vibrating materials. It will also depend on how long your employees are exposed to vibration and at what level. As a simple guide you will probably need to do something about vibration exposures if any of the following apply:
Do your employees complain of tingling and numbness in their hands or fingers after using vibrating tools?
Do your employees hold work pieces, which vibrate while being processed by powered machinery such as pedestal grinders?
Do your employees regularly use hand-held or hand guided power tools and machines such as:
• Concrete breakers, concrete pokers;
• Sanders, grinders, disc cutters;
• Hammer drills;
• Chipping hammers;
• Chainsaws, brush cutters, hedge trimmers,
• Powered mowers;
• Scabblers or needle guns.
Do your employees regularly operate:
Hammer action tools for more than about 15 minutes per day; or
Some rotary and other action tools for more than about one hour per day.
Do you work in an industry where exposures to vibration are particularly high, such as construction, foundries, or heavy steel fabrication/shipyards?
There are hundreds of different types of hand-held power tools and equipment which can cause ill health from vibration. Some of the more common ones are:
• Concrete breakers/road breakers;
• Cut-off saws (for stone etc);
• Hammer drills;
• Hand-held grinders;
• Impact wrenches;
• Needle scalers;
• Pedestal grinders;
• Power hammers and chisels;
• Powered lawn mowers;
• Powered sanders;
• Strimmers/brush cutters.
