Methods of assessment

 

 

HAVwear has the capability of providing layered HAVs risk exposure data of both TEP and SEP:

 

1

Tool Exposure Points (TEP) are calculated using the HSE risk assessment Exposure Points system,  combining the length of time a tool is in use (trigger time) with the vibration value that is programmed on the HAVwear Tag. The validity of the value programmed in the HAVwear tag is a responsibility of the employer to be “representative of the tool use by their operators”. A number of sources for the pre-defined magnitude can be used and the HSE will look for justification of choice.

 

  

2

 Sensed Exposure Points (SEP) are calculated by the same HSE risk assessment methodology but utilises a real-time vibration magnitude level sensed at the wrist, in combination with the length of time a tool is in use (trigger time).  If SEP data is solely used, the HSE will look for evidence that SEP vibration levels are appropriate.

 

In summary the only difference is the source of the vibration magnitude.

The employer always has access to both TEP and SEP data which are stored online. However, to avoid confusion to the tool user, the HAVwear monitor displays only one points system.

The employer chooses TEP or SEP to be displayed on the monitor.  This choice is based on their assessment of which vibration is most probably that faced during tool use - the static tool data for TEP or the sensed vibration on the wrist for SEP.

Everton Football Club - Richard Cairns, Health & Safety Manager

“Hand Arm Vibration Syndrome is not just a problem for people using industrial power tools in the construction or manufacturing sectors – it can affect anyone who regularly uses other vibrating equipment including mowers and strimmers. We have dozens of lawnmowers that are in daily use at Goodison Park and our training complex at Finch Farm, so we have to have a monitoring system that is simple and effective. “In the past we relied on timesheets and individual record-keeping to monitor vibration exposure, but the HAVmeter system is a far superior method of doing this. All of the information is collated by the devices and provides us with a comprehensive overview of how much exposure each member of staff is subjected to. If they reach the safe limit stipulated by the HSE, then they are alerted to the danger at once – meaning there is no chance of over-exposure. “However, it is not just a good tool for preventing injuries. The system allows us to generate reports about the vibration levels of our equipment, so we can identify which machines need to be replaced or upgraded. It’s a very versatile piece of kit that will continue to be hugely beneficial to our groundskeeping operations in the future.”
