Rank: Guest		Posted By MP Grayson Should have added. They may have some kit that will be good for the task (before someone points out that stain tubes are not the answer) or know where you could get it. Crack on again.

Rank: Guest		Posted By Neil Cooper Hi Todd You are looking at measuring polyaromatic hydrocarbons such as benz-pyrene, quite tedious and rather expensive. Contact an occupational hygiene company.

Rank: Guest		Posted By Todd Hallam Thank you. Would a Drager tube tester suffice?

Rank: Guest		Posted By Alan Hoskins There are instruments for checking these fumes but they are expensive (very). If you have to do it perhaps better to hire someone who has the kit and knows how to use it? Alan

Rank: Guest		Posted By graeme12345 Todd, I have never heard of anyone asking for this before, why are the figures needed?

Rank: Guest		Posted By Todd Hallam How do you know if you are exceeding the Occupational Exposure Limits ie; For Asphalt, petroleum the 8hr TWA of 5mg/m3?

Rank: Guest		Posted By graeme12345 Because if this work is outside in the open air, there is no need to know that, no HSE inspector is going to ask you for them, What are you going to do when you know what they are?, Ther is no significant risk from these fumes if you are in the open air so why bother. there are other more important hazards which have priority and need to be controlled for this type of work.

Rank: Guest		Posted By Todd Hallam Apologies, I should have mentioned that the product is going down to re-lay the base floor within a fuel depots tank. There will be air flow as the tank will be jacked up with safe access/egress points. Confined Space trained ops with BA rescue, organic respirators, rotational work etc etc. Just needed to know how to measure the OES.

Rank: Guest		Posted By MP Grayson Todd. Dragers dont work for fume and dust. But as a major company they may have the answer. Crack on

Rank: Guest		Posted By Paul Leadbetter Todd You should use an occupational hygienist; check out the bohs directory here: http://www.bohs.org/reso...ants_directory100408.pdf Paul

Rank: Guest		Posted By Smiff You can hire a PID (Photo Ionisiation Detector) from the likes of HSS or Shaw City. They will demonstrate how to calibrate it with the supplied span gas and you are sorted. They give real-time readings in ppm. Ask for a bulb appropriate for measuring benzene. I measure tar fumes as per benzene as this is the highest cat. of the componenents, so gives you the greatest safety margin.

Rank: Guest		Posted By graeme12345 would'nt there be a standard reading for this that you could get it from someone who had carried this out previously / before?

Rank: Guest		Posted By Anthony Edwards Todd, as suggested use an occupational hygienist. I asked about measuring welding fume/soldering fume in a working environment and was informed they now measure the individuals exposure and not the workplace. Don't shoot the messenger! Regards Nutty

Rank: Guest		Posted By Jay Joshi Start with the MSDS for the type of Bitumen that is going to be used and the treatment temperature. There are various grades of Bitumen You should be able to get technical/health & safety support from the manufacturer even if a distributor may not be that supportive. Bitumen is made up of complex hydrocarbons, but most Bitumen used is of the "oxidised" category--and your worry should be generation of hydrogen sulphide rather than benzene. There is an HSE WEL for Asphalt fume. Otherwise consult an Industrial Hygienist for definitive information--there is a CDC/NIOSH method for gravimetric determination of asphalt fumes;- http://www.cdc.gov/niosh/nmam/pdfs/5042.pdf http://www.cdc.gov/niosh/topics/asphalt/

Rank: Guest		Posted By Jay Joshi Another point is that if you are going to use Respiratory Protection as an additional control measure, is it essential to measure the fume levels??
