Afternoon all.

I am the SHEQ Manager for automotive manufacturing group. At one of our sites we produce carbon composite steering wheels. Part of the 'lay up' process involves placing strips of pre cut carbon shapes into moulds for cooking. During this process, to get the carbon layer into the nooks and crannies of the mould, hair driers are used to gently warm up the carbon so it can be manipulated and pushed in.This is standard industry practice as other tools such as heat guns are too hot. The issue we are having is tiny particles of carbon fibres (which are conductive) and being sucked into the hair drier fans and causing them to blow. This has caused 2 minor electric shocks to staff. We have even had a PC blow too. We have consulted with other carbon composite manufactures and they are having the same issue and say theer is nothing that can be done. We are looking into various engineering controls such as bench LEV units, but does anyone else have any experience with this issue that could recommend the best way forward... Thanks

good suggestion from A. I have no real experiance in this area but im thinking that its because the air intake on a hair dryer is so close to the outlet that this is why the fibers are being drawn in. Its is not possble to find a heat source/blower with a long hose to provide the heat but put the ait in take outside the area covered by the LEV?  Its not quite the same but when using mobile compressors using breathing air we used to have to do something similar to stop the CO from the exhaust being drawn into the air supply.
