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.

Testimonial:

Norfolk County Council Environment Transport & Development - Colin Tibbenham

“We needed a better monitoring system in place to make sure we knew who was working with what machinery and for how long. After reviewing a number of potential solutions, we decided on the HAVmeter because it was the only option that ticked all the boxes for us In terms of accountability as it could give us detailed records of what our teams were exposed to. We purchased one HAVmeter for every worker in our Environmental & Waste and Highways divisions – a total of 250 - which means we now look after everyone who works with us at any given time, including our partners and sub-contractors. If they work with us, then they have to comply with our safety rules. Through our investment in preventing HAVS we have been able to reinforce the message to our workforce that Norfolk County Council takes health and safety very seriously and that we care about and value our workers. Also, the devices mean we now have a robust defence in place to protect us against any claims.”
