Preventing Isocyanate Exposure

Friday, December 19th, 2014

As previously reported in CRASH Network, the Occupational Safety and Health Administration (OSHA) is stepping up inspection of collision repair shops as part of a 3-year emphasis on protecting workers from isocyanate exposure (CRASH 4/28/14).

Catherine Sayles of Bayer Material Science, a raw material supplier of isocyanates to paint manufacturers, shared some advice for shops during a presentation at the Collision Industry Conference last month. Her company recommends the use of nitrile gloves (not latex) when working around isocyanates, but cautioned that shops can no longer presume that “blue gloves” are nitrile as opposed to just latex.

“In the past, the latex manufacturers always made their gloves white and the nitrile gloves were blue,” she said. “Now the manufacturers of latex gloves are also making them in different colors, including blue. So there’s confusion sometimes as to whether a blue glove is latex or nitrile. You want to make sure you’re paying attention to the box and what kind of glove you’re using, because latex gloves are not adequate for isocyanate protection.”

OSHA is also testing parts of the shop away from the paint area to see if, for example, a painter wearing a spraysuit into the shop lunchroom has left isocyanates on a chair. How long do isocyanates on such surfaces pose an exposure risk for others? Sayles said it varies.

“If it’s still wet, I would definitely say you have that potential,” she said. “Once it’s dry, it depends on how much of it is there, how thick it is, how much isocyanate is actually in the product.”

She said shops can check for surface or skin contamination from isocyanates – after clean-up of a spill, for example – by using Swype test kits for aliphatic isocyanates. According to the National Institute for Occupational Safety and Health (NIOSH), workers improperly exposed to isocyanates can suffer permanent respiratory complications, and even death, from a single episode of overexposure or intermittent exposures at low concentrations.

PRODUCT SPOTLIGHT – Barracuda Immersion Separator

Tuesday, December 2nd, 2014

Designed specifically for the capture of flammable or combustible dust and debris, like aluminum and titanium, the Barracuda’s powerful vacuum motor draws air and collected particulate into the immersion tank, and forces it through a roiling water bath, instantly quenching sparks, and thoroughly wetting dust out of the airstream. Three stages of additional filtration ensure that the air exhausted from the system is dust and moistbarracudaure free.

When its time to empty the tank, simply pull the valve lever to dump the water and debris out through a 5 micron filter sock and into any floor drain. Once the tank is empty, connect the system to a normal garden hose, and a series of spray heads inside the unit continue to flush the tank, ensuring that no sediment builds up on the internal components. The large window makes it simple to confirm the water level in the tank, and allows spectators to view the carnage as dust and debris gets consumed by the Barracuda.

Whether you’re installing a Barracuda system in your automotive bay or your aircraft hangar, you’ll be extremely satisfied with the low maintenance and ease of use. And with a lifetime warranty against manufacturer’s defects, you’ll have peace of mind knowing that this equipment solution is a one-time purchase.

Features:
• Provides 100 CFM & 100” H2O
• Vacuum and accessories are electrically bonded to ensure conductivity during use
• Conductive bonded Hydrophobic HEPA filter: Efficiency of 99.97% @ 0.3 micron
