If it was your job and you did it everyday for 10 years you might have problems but other than that I think the threat is minimal
No guys. Im afraid this isnt one of those cases. Chromium hexavalent is bad news period. When you weld steel all day long it really doesnt matter. Thats like saying 'I get dust all day long from cars riding down a dirt road, so a little asbestos isnt going to hurt me'. It just doesnt work that way.
Take proper precautions if your burning stainless. Long sleeves, gloves, etc. When your done let the clothing that has been exposed air out for a day before washing it as the chromium breaks down very quickly. I know some people are not going to heed this, but at least your not going in blind now.
From the OSHA site. The amount OSHA will let a worker be exposed to is basically.... ANY
ie... if your company exposes you to ANY fumes from cutting stainless then they broke the law. Its worse the asbestos exposure.
SUMMARY: The Occupational Safety and Health Administration (OSHA) is
amending the existing standard which limits occupational exposure to
hexavalent chromium (Cr(VI)). OSHA has determined based upon the best
evidence currently available that at the current permissible exposure
limit (PEL) for Cr(VI), workers face a significant risk to material
impairment of their health.
The evidence in the record for this
rulemaking indicates that workers exposed to Cr(VI) are at an increased
risk of developing lung cancer. The record also indicates that
occupational exposure to Cr(VI) may result in asthma, and damage to the
nasal epithelia and skin.
I make a living looking out for things like this. It really is that bad. The worst thing you could do is play it down for those not in construction that dont have any idea. Their wife and kid might be looking over the shoulder when they cut the next part
