SDS sheet / COSHH assesment for Car exhaust fumes
Rank: New forum user

For a 3rd party customer we provide traing to , we are being asked about COSHH assesment for exhaust fumes from vehicles in their workshops , we do have them for the fuel itslef , so would have thought this would cover it. From a report back on a service to the LEV system they have implied we need sds & assesments for the bi-product , i.e the soot etc that is left behind in the LEV between services. Any advice is welcome. Andy

This stuff is not a product and does not have a supplier, so it doesn't need to have a safety data sheet and there is no one to write one. All you can do is take what you know or can find out about its chemical composition and physical state, identify the corresponding hazards, and write a COSHH assessment based on that.
COSHH assessments don't have to be based on safety data sheets, even though the form you use for them may imply this.
The hazards of exhausts are very different from the hazards of the fuels they are emitted from because they are chemically very different.

You not only have the fuels to consider but any additives such as AdBlue / biodiesel / ethanol along with lubricating oils from the engines, anti-freeze & other coolant additives which can all end up passing out of the exhaust system.
Then there are considerations around the combustion process - excess air / insufficient air / temperature. If there are multiple vehicles you then add further variability for glow plug / spark plug condition. A fully definitive answer as to the "soot" composition would only come from a full chemical analysis.
