Hi, I have previously asked a similar question before regarding this matter but wondering if any one can just help me confirm! I have completed a risk assessment for 2 x diesel sideloaders entering a factory floor and the diesel fume issue related to this.
The sideloader is only in the building on infrequent times and only for short duration. The factory floor is a large area with high roofs and adequate ventilation.
I assessed the risk as being low but have reviewed the benefits of fitting a 2 way Non Regulated Catalyser that reduces CO content by 95% and the HC content by 75%. Now i feel that this should be more than adequate but as i've never dealt with this before i was wondering if anyone could advise me if we need to have monitoring done as well or would the above be adequate controls enough? I personally think it is.
Cheers for any help, Gavin

Gavin,
Reducing the toxic content of the exhaust fumes in the building is an obvious precaution, but if you do not know what the current position is you might be fixing a problem that just doesn't exist. Has any monitoring been done already?

Hi Ken,
Thank you for your reply. No there is has not been any monitoring carried out. This has come of the back of an employee question asking if the fumes where harmful when in the factory. As i said previously we don't feel there is a problem as the vehicle enter rarely and for short stays and the size and ventialtion of the building is very good but we figure by reducing what comes out of the diesel exhaust will be just that extra blot and brace for us. Its the monitoring issue thats just nagging at the back of my mind.

Gavin,
In that case the "correct" answer is have some proper monitoring done for a day measuring, say, CO, to give an indication of the level of exhaust fumes staff are exposed to. This should give an indication of all other constituents from the known make up of diesel exhaust fume. From memory of a number of years ago, diesel exhaust fume is predominantly particulate, soot and the like. A specialist contractor should be able to advise on the sampling required, but look for TWA and peak data. If normal working comes out at well below (less than half) the WEL you've established control. I also seam to remember there are some carcinogens in the fume (PM10s or something) so this might influence the decision.
Hope that's of help.
Ken

you can get LEV systems specifically designed for such kit - especially in construction where such kit is regularly used - try the web -
such kit is cost effective especially when you weigh up the time etc you spend in undertaking a 'proper' COSHH risk ass etc
try putting jenny equip outside

Posted By John Murgatroyd http://www.hse.gov.uk/pubns/indg286.htmIt has been discussed before. Do your lift trucks run on red diesel ? Yes ? Then that is high sulphur diesel, so sulphur dioxide is also going to be a problem bearing in mind the product of it being absorbed by moisture in a persons lungs. There are many problems associated with diesel fume in the workplace, the above URL gives you a good run-down. As far as I can remember, a catalyser is of no use if the diesel contains a high percentage of sulphur.
