How should I sample to comply with OSHA’s silica dust standard?

“So, silica…”dusty

This was how many conversations started while exhibiting at conference  last week. OSHA released its rule for occupational exposure to respirable crystalline silica back in March and many are still looking to understand how it will affect their business and employees.

The new rule goes into effect on June 23, 2016 and most business will have between one to five years to comply depending on industry. The new standard reduces the permissible exposure limit (PEL) for respirable crystalline silica to 50 micrograms per cubic meter of air, averaged over an 8-hour shift. This is a reduction is two to five times lower than the previous PEL.

11 ways you may be using your gas detection tubes incorrectly

Ever send someone out to collect samples with a gas detection pump and tubes that may not have received proper training? Ever have a time where you received inaccurate data? What did that mean for you? Believe it or not, there are still many people who do not use gas detection tubes properly.

3) Improperly storing tubes: If tubes are allowed to get hot in storage, or they are left exposed to the sun, they may not respond properly, due to advanced aging.
