Hi,
Im just about to start noise assessments in my company (Construction). Im presently making a list of all plant / equipment that need to be assessed.
Would anyone have a sample site noise assessment or plant / equipment noise assessment that i could take a look at just to get an idea how to lay the assessment out?
Thanks
Nicky

You should be eliminating or reducing exposure to noise rather than measuring the noise that particular item of plant or equipment makes.
Your risk assessment should be task/individual/group based.
It is more than just using a SLM to take measurements of noise - sometimes measurements may not even be necessary. It is the noise eliminating/reducing controls that are the key.
As for a template, get a copy of L108 - its all in there!

It is all in there, "Part 2: Managing noise risks: assessment and planning for control" I think that Nicky is taking the correct approach, initial assessment, identify significant risks, eliminate or introduce controls.

Oh Anthony, be fair to Nicky; it needs measuring to establish required reduction levels first, to ascertain perhaps not that it does, but by what level and what is the best methodology to achieve that.
Nicky may well not be aware of the hierarchical procedures in obtaining a result; at this stage however it is just a sample assessment that has been requested to compare to, or bounce ideas from folks with experience in this particular field.

Nicky,
Apologies if it seemed like I came over as unfair, it was not my intention.
The point I was trying to make (sometimes difficult on a forum) was that sometimes noise can be simply be eliminated or reduced without taking SLM measurements. You can replace something that you think is "noisy" with something that is not. For example rusted fasteners can be removed by using hydraulic shears rather than being ground off with a petrol disc cutter.
The other point I tried to make was that measuring the noise of a roadside compressor may give you a false assessment if, when in normal use, the operator stands at the end of 10mtrs of air line.
It is deciding WHO may be harmed and why.

One of my first tasks when I became the H&S Advisor for my organisation (a print and Direct Mailing house) was to look at the sound levels being generated.
All my equipment is under 2 years old, all CE approved, all fitted with the required sound suppression hoods. They are all serviced at no more than 12 month intervals, usually 6 monthly.
However, I still needed to establish a base-line and appreciate how the sound reverberated around the environment. I also need to see where the sound levels were in relation to the legislation. So, I got a sound metre and did a variety of readings at various times, in various locations within the production halls and with differing amounts of equipment running. The metre was set to give readings on a c rating (8 hour day) and from that I was able to advise the directors accordingly.
Ultimately, I aimed for suppression/replacement but in one situation I had to recommend hard ear defence had to be used.
I didn't generate a machine specific RA, but did keep a simple Excel spreadsheet of the readings, date, time, location and equipment in operation.
What I did seemed to have served it's purpose, and I hope this gives you some help Nicky.
