13. Controlling Exposure
Notes for delegates attending HAV Management Essentials Programme 13

14. What do points make…
Job 1 - Risk Assess jobs being done and equipment used – Eliminate exposure
Job 2 – Control - HSE Vibration Points
Exposure Action Value – 100 Points – keep below if possible and make sure health surveillance is done
Exposure Limit Value – 400 Points – maximum a worker can be exposed to in a working day
Notes for delegates attending HAV Management Essentials Programme 14

15. Managing the Risk Risk Assessing is simply done: Look at the whole job
How many workers
What equipment is being used
Different equipment exposes the worker to different amounts of vibration
This is known as the vibration dose

Notes for delegates attending HAV Management Essentials Programme 17

18. Case Study - George Vibration magnitude of CP9 at the time – 32m/s2
Points per hour = (MxM)x2
(32 x 32) x 2 = 2048 point per hour
Or 34 points per minute
EAV (Exposure Action Value – 100 points) in 3 minutes
ELV (Exposure Limit Value – 400 points) in 12 minutes
George was regularly getting >8,000 points per day

21. Trigger Time
Notes for delegates attending HAV Management Essentials Programme 21

22. Measuring Trigger Time
A timer linked to the power source
A stop watch - operated by 2nd person
A timer activated by vibration that also monitors points e.g. The HAVi

Planning – CDM 2015
Notes for delegates attending HAV Management Essentials Programme 24

25. CDM 2015 – Regulation 12
The construction phase plan must set out the arrangements for securing health and safety during the period construction work is carried out. These arrangements include site rules and any specific measures put in place where work involves one or more of the risks listed in Schedule 3
Work which puts workers at risk from chemical or biological substances constituting a particular danger to the safety or health of workers or involving a legal requirement for health monitoring
Notes for delegates attending HAV Management Essentials Programme 25

26. Conclusion Remember HAVS has no cure but its progress can be halted
Its now easier to prevent than ever
Job risk assessment should aim to keep exposure below 100 points per person
Legal limit is 400 points in 1 shift – for emergencies!
HAVi is a simple essential piece of PPE

27. HAVi Training ARange of training options including:
IOSH HAV Management Essentials – 1 day
HAV Essentials – ½ day
HAV Basics – 2 hour
New 1 day courses – to be accredited
Construction Dust Management Essentials
Noise Management Essentials
