What the law requires

  • Control of Noise at Work Regulations 2005

– Guidance in L108

  • Control of Vibration at Work Regulations 2005

– Guidance in L140 (HAV), L141 (WBV)

  • RIDDOR 2013

– Reporting of HAVS and CTS

  • Supply of Machinery (Safety) Regulations 2008

– Low noise, low vibration machinery – Noise and vibration information facilitating choice and helping with risk assessment

BIRD – Back Injury Risk in Drivers

  • WBV can cause

complaints of discomfort or injury

  • BIRD helps you

identify the most likely cause of injury

  • WBV likely to

aggravate – not cause

Backrest control

The backrest control should be in good condition and fully operable. It allows the driver to achieve effective back support, and help adjust the reach between hands and feet. 3 Backrest control sometimes difficult to operate The seat suspension control should be in good condition and fully operable. The suspension is critical to providing effective vibration control. 4 Seat suspension control difficult to operate or access 4 Seat needs some attention and may need replacing Seat coverings in good condition. Seat padding slightly compacted. Fore-aft control sometimes difficult to operate. Seat repair work required Repair/maintain fore-aft control.

Seat padding

Seat padding is a component of vibration control, and aids general comfort and support. 2 Seat padding slightly compacted

Fore-aft control

Fore-aft controls should be in good condition and fully operable. They allow the seat to be positioned such that the driver can comfortably reach a little beyond all main hand and foot controls. 3 Fore-aft control sometimes difficult to operate 2 Seat coverings in good condition

BIRD Tool

Not set

Seat coverings

Seat covering condition is an indication
  • f the general condition of the seat.
Seat condition and set up are crucial to allowing workers to achieve a good posture that can be maintained comfortably whilst driving. The seat should be in good condition, that means:
  • padding and seat covering in good condition,
  • key controls for seat adjustment working and easy to operate (if the seat does not have the control, select 'not applicable').
NOTE - This section is about seat condition; the next section looks at the use of the seat and whether it is set up correctly. <- Prev. Next -> Reset Summary

Noise – Employer liability claims

slide-9
SLIDE 9

Liability claims – HSE response

Why so many claims for deafness?

  • Are appropriate noise controls in place?

– Difficult to source in some sectors

  • Proper use of noise control equipment?
  • Buying Quiet?
  • Are hearing protection programmes working?

– Selection of suitable hearing protection? – Training of workers and supervisors? – Health Surveillance?

slide-10
SLIDE 10

Buy Quiet – Market Surveillance

  • European joint market

surveillance action on safe use of chainsaws –including Noise and HAV

  • 20dB difference between

noisiest and quietest chainsaws –BUT not all chainsaws equally efficient

slide-11
SLIDE 11

Buy Quiet

  • Find tools good at the job

–Avoid unnecessarily high noise models

slide-12
SLIDE 12

NOMAD European project to –

  • Improve compliance with noise

requirements on manufacturers –Noise information used to compare actual noise with the state-of-the- art noise control –Value(s) should represent noisiest typical use

Do I have to Measure Vibration?

slide-16
SLIDE 16

What can we do?

NO

  • Identify your risks and

how to control them

slide-17
SLIDE 17

Eliminate exposure to HAV

  • Low maintenance planting
slide-18
SLIDE 18

Substitute lower HAV equipment

  • Remote Control – reduce

noise and vibration, also could be faster

slide-19
SLIDE 19

Administrative controls

  • Last resort

– Job rotation – Time limiting

  • Plan the work
  • Traffic light system
slide-20
SLIDE 20

PPE

  • No PPE for HAV
  • Gloves and warm clothes

help reduce likelihood of symptoms, not exposure

  • You should assume no

protection from ‘anti- vibration’ gloves

slide-21
SLIDE 21

Sources of vibration data

  • Measured vibration magnitude

– HAV – 3.3 m/s2 (4.5 hrs to EAV)

  • Manufacturer data

– HAV – 2.8 m/s2 (6.5 hrs) – WBV – 0.5 m/s2 (8 hrs)

  • Measured vibration magnitude

– HAV – 5.5 m/s2 (1.5 hrs) – WBV – 1.9 m/s2 (30 mins)

Sources of vibration data

slide-23
SLIDE 23

Sources of vibration data

  • Caution required to

avoid misleading data

  • Standard tests usually

produce good data for some tools in a class

  • Best to share good

data

slide-24
SLIDE 24

Sources of vibration data

  • Use recommended initial value for RA
  • Range indicates whether lower vibration

alternatives may be available

  • Responsibility on dutyholder to demonstrate

validity of their data if using lower values

slide-25

Buy Smooth

Find tools capable of the job Avoid the models with unnecessarily high vibration (LowVib)

HAV – Too much data? Not enough control!

  • Too many sellers of measurements

– Assessment is to find out how to comply

  • Is there a risk?
  • What control measures will work?
  • Too many suppliers of monitors

– Continual monitoring unnecessary

  • Too few advisers on good practice

– Most companies know what to do but lack confidence

slide-27

http://www.hse.gov.uk/vibration/hav/index.htm Exposure monitoring Q&A

slide-28
SLIDE 28

Exposure monitoring

  • No HSE requirement for

continual monitoring

  • If measurements must be

made, instruments to comply with ISO 8041

  • Effort should be directed

at control ALARP and health surveillance – not monitoring

slide-29
SLIDE 29

Information, Instruction and Training

  • Employees to know:

–vibration risk –control measures –how to identify and report signs and symptoms –how health surveillance will help them

slide-30
SLIDE 30

Health Surveillance

  • To keep people in

work

  • To prevent

progression

  • To avoid disability
  • Consider change of

job

  • No safe level

(negligible risk at 1 m/s²)

  • Presentation only, not for circulation
slide-31
SLIDE 31

Key messages

  • Assess wisely – to identify controls
  • Control the risk
  • Share success stories

–The good processes and tools

  • Share typical-use emission values
  • Prevent disability – use health

surveillance findings
