What training is required to carry out dust monitoring? Where can you buy the equipment? Does anyone perform this in-house?
I am weighting up the cost of paying for an annual wood dust monitoring service and taking it in-house. I have an analytical science background and cannot see the difficulty in carrying out dust monitoring myself (inline with MDHS 14/3) if the cost of the equipment is reasonable.
I am also interested in looking at the same situation for VOCs associated with paints and lacquers.
Can anyone provide advice?

Posted By Descarte I think the BOHS would be the best bet for an accredited course: http://www.bohs.orgThey will also likely be able to tell you about local registered course providers etc... Good luck, its an interesting and rewarding area

I attended a course (years ago) run by SKC that explained the use of the equipment - both dust and vapour testing. I never needed to conduct dust monitoring and I always sent the VOC tubes to an accredited lab for analysis. Their equipment is good but there are other labs out there.
Essentially you can do this all yourself but you lose the credibility of an external accredited body - you could potentially tamper with the results to protect yourself / your employer, etc.
Best of luck

Dave,
I cannot believe how much labs are charging for a relatively simple test. The only benifit I can see from using an external body is that they are independent.
But I am finding difficulty in sourcing a company that will provide costs for the equipment eg IOM head, sample pump, calibrator, 6 place analytical balance,filters etc.
I need the figures to see how long it will take to balance purchasing the equipment with buying in the monitoring sevice.
I suspect with calibration costs it may take 3-4 years, however if regular dust monitoring is required then it may still be worth buying the equipment.

Just about anyone can carry out dust monitoring; VOCs can be a bit more involved but your analytical background will probably help. The trick is in interpreting the results; use a competent occupational hygienist. The BOHS Directory will help: bohs.org.

Leave it to a reputable contract lab, but we are a contract lab so I would say that wouldn't I !
Also factored into your internal cost should be the calibration of the flow-meter and the balance by an accredited calibration service.
For a contract lab the overhead associated with small sample numbers is very significant and may be a factor in the quotes. Some might occasionally agree to work at a loss for various reasons. Others are forbidden by internal rules to do this.
The perception of prices by customers can be influenced by how they would price their own time doing it in-house. Some might price their own time at zero which makes a big difference to their perception.
