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.

Health and Safety Health and Safety Executive 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

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 • Manufacturer data – HAV – 2.8 m/s 2 (6.5 hrs) • Measured vibration magnitude – WBV – 0.5 m/s 2 (8 hrs) – HAV – 3.3 m/s 2 (4.5 hrs to EAV) • Measured vibration magnitude – HAV – 5.5 m/s 2 (1.5 hrs) – WBV – 1.9 m/s 2 (30 mins)
http://www.hse.gov.uk/vibration/hav/index.htm Sources of vibration 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 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
http://www.hse.gov.uk/vibration/hav/index.htm 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
• Presentation only, not for circulation 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)
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
