Hi Ladies and Gents
Looking for a little bit of guidance if possible, i work in the motor industry and as you can expect have a major issue with noise in the workplace.
Under the old Regs the following exposure times were in place;
dB(A) Exposure
85 8 hours
88 4 “
91 2 “
94 1 “
97 30 minutes
100 15 “
103 7.5 “
106 3.75 “
However i can't seem to find any similar guidance under the new regs can anyone point me in the right directions as to what these exposure limits will now be?
Any help will be greatly appreciated
Thanks
Dez

The guidance you were looking at was based around a 3 dBa rise giving a doubling of the sound pressure. Thus if you start at the new equivalent to the old 85, ie 80 dBa then you get:
80 - 8 hours
83 - 4 hours
86 - 2 hours
89 - 1 hour etc etc
But do remember that if the weekly exposure is 87dBa, after accounting for hearing protection used, then you must review everything in your control measures to ensure that it is brought below 87 dBa, on a weekly personal exposure. At 85 hearing protection must be supplied and used. Together with other control measures including noise protection areas if other controls cannot be used.

thanks Guys, i think i'm on the right track now! But trying to get guys to wear hearing protection when using air tools with noise in excess of 95dba is a nightmare. Maybe its a macho thing :)

This is the time you need to start getting formal about the use of HP. I rather think the HSE will soon query why you are not enforcing the issue with appropriate management actions.

Agree with Bob, but don't forget HP should be the last resort and you should be looking at other ways of reducing exposure. E.G. quieter tools, reduced exposure time etc.

Take them into a meeting, insist they wear earplugs in the meeting, tell them about the risks and impacts of hearing loss, then ask if everyone heard what yu were saying.
That should demonstrate to them the potential consequences of not wearing HP.
Ear plug attenuation approximates to level of hearing loss likely to be experienced over time!

having just been involved in a case, please can i suggest you do the training already recommended (how noise affects hearing; types of protection; aquisition, repairs, replacements; hygiene aspects; storage; where the noise zones are etc - but, importantly, get every attendee to sign a receipt of attendance and UNDERSTANDING of the requirements.
