IOM report
An independent report by the IOM on the validity of the data produced by Reactec’s HAVwear to inform a suitable and sufficient risk assessment.
The Institute of Occupational Medicine (IOM) was requested by Reactec to conduct an independent review of data collected using the HAVwear system and subsequently provided a report in January 2018.
-
It uses a tools pre-defined vibration magnitude and length of time the tool is in use to calculate exposure points in accordance with The Control of Vibration at Work Regulations 2005 and HSE guidance. Reactec name this type of exposure points as “Tool Exposure Points” (TEP).
-
It also determines the vibration transmitted to the tool wearer’s wrist and mathematically corrects for the energy loss between the wrist and the tool grip point. The HAVwear uses this determined vibration magnitude and the length of time the tool is in use to calculate exposure points relating to real-time vibration exposure experienced by the wearer. Reactec name this type of exposure points as “Sensed Exposure Points” (SEP).
The IOM report concludes:
|
- The IOM firstly reviewed data collated by Reactec from 23 tool onsite scenarios with up to 3 simultaneous test methodologies – HAVwear and two ISO5349 compliant instruments. Each tool was tested up to 30 times. The IOM statistically analysed the data for consistency and correlation.
- From phase 1 the IOM determined a range of tools to evaluate autonomously which would yield a broad spectrum of tool behaviour. The IOM undertook 477 independent tests of 40 tools covering 16 tool types. The work was carried out in real tool use environments including road maintenance, forestry & grounds maintenance, workshop, and garage repair shops. The aim of this phase was to consider the HAVwear as a risk assessment and or a risk management tool.
