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

Summary:
Recommendations:
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.

Backrest control sometimes di fficul t to operate
The seat suspension control should be in
good condition and fully operable. The
suspension is critical to providing
effective vibration control.

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.

Seat padding s l ightly 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.

Seat coveringsSeat covering condition is an indication
of 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.

Summary
Health and Safety ExecutiveHealth and Safety Executive
Noise
Noise – Employer liability claims
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?
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
Buy Quiet
•Find tools good at the job
–Avoid unnecessarily high
noise models
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

Hand-arm vibration
(HAV)
Do I have to Measure Vibration?
What can we do?
NO•Identify your risks and
how to control them
Eliminate exposure to HAV
• Low maintenance planting
Substitute lower HAV equipment
• Remote Control – reduce
noise and vibration, also
could be faster
Administrative controls
• Last resort
– Job rotation
– Time limiting
• Plan the work
• Traffic light system
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
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)

data
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
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
Buy SmoothFind 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

Exposure
monitoring
Q&A
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
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
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
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
Have a good day…
