Controlling Exposure Notes for delegates attending HAV Management Essentials Programme 13

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

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 15

George Notes for delegates attending HAV Management Essentials Programme 17

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 Notes for delegates attending HAV Management Essentials Programme 18

Trigger Time Notes for delegates attending HAV Management Essentials Programme 21

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 Notes for delegates attending HAV Management Essentials Programme 22

Equipment maintenance Anti vibration gloves??? Health surveillance Other Controls Train your team Ergonomics Equipment maintenance Anti vibration gloves??? Health surveillance Planning – CDM 2015 Notes for delegates attending HAV Management Essentials Programme 24

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

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 Notes for delegates attending HAV Management Essentials Programme 26

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 Notes for delegates attending HAV Management Essentials Programme 27
