What is HAV?

28.04.2005
 

Hand Arm Vibration (HAV) is vibration transmitted from work processes into workers hands and arms. It can be caused by operating hand held power tools or by holding materials being processed by machines such as pedestal grinders.

The HSE estimates that there are around 36,000 people with an advanced stage of vibration white finger (VWF) which is the most well known form of hand arm vibration syndrome. VWF is also one of the most common resaons for occupational ill health claims made against employers.

HOW CAN TOOL AND MACHINE MANUFACTURERS HELP ?

Equipment manufacturers are generally trying to improve the vibration performance of their products, so new tools and machines are likely to emit lower vibration than older equipment.  You will gain the maximum benefit from these improvements if you introduce a policy of buying the most suitable equipment when you replace tools or machines.

For most types of equipment, manufacturers are required by law to:-

 

* Design and construct equipment which will cause the minimum risk of vibration injury
* Provide you with warning of any residual risks from vibration
* Provide you with information on vibration levels
* Provide you with instructions on how to use the equipment to avoid risks from vibration

 

You should aim to buy the lowest vibration equipment suitable for the job.

Vibration levels are identified in units of metres per second squared (m/s2)

WHAT DOES THE LAW REQUIRE YOU TO DO ABOUT THESE RISKS ?

H&S law requires you to do a number of things to protect your employees.  You should:-

 

* Assess the risk to the health of your employees and plan for its control - manage the risk
* Provide suitable equipment for your employees' use
* Maintain equipment correctly
* Give your employees information and training on health risks and safe use of the equipment
* Provide health surveillance of your employees where risks cannot be completely eliminated
* Provide reports to the relevant enforcing authority on cases of HAV syndrome in your workforce
* Consult your safety or employee representative on your proposals to deal with vibration hazzards

 

WHAT YOU CAN DO TO CONTROL THE RISK

There are many things you can do, several of which may cost very little and could also improve productivity and product quality

Look for alternative ways of working which may eliminate the vibrating equipment altogether.  For example, by using the Spit Pulsa 700E cordless gas nailer instead of drilling

Make sure your employees use the most appropriate equipment for each job

Minimise the time individuals use the equipment (eg. faster more efficient equipment, job rotation).  The Spit Pulsa 700E is the fastest way to install cable management and wiring accessories

 

Maintain tools to the manufacturers specifications to avoid worsening vibration. 

For example:

 

* Replace vibration mounts before they are worn out.
* Ensure rotating parts are checked for balance and replace them if necessary.
* Get advice from the equipment manufacturer on safe use of the equipment. 
* Introduce a purchasing policy specifying low vibration performance for new equipment.
