What is the new OSHA Silica Rule?
OSHA’s new silica rule is meant to protect workers from exposure to respirable crystalline silica (RCS) on jobsites. The Rule establishes a new 8-hour time-weighted average (TWA) Permissible Exposure Limit (PEL) of 50 µg/m3, an action level (AL) of 25 µg/m3 and a host of ancillary requirements.
What is RCS?
Respirable crystalline silica is a common mineral found in many naturally occurring and man-made materials.
Where is drywall finishing specifically discussed in the OSHA regulation?
Page 469 of regulation 29 CFR 1926.1153.
How does the new silica rule apply to Sheetrock® Brand ready-mixed joint compound?
The silica rule is a jobsite regulation designed to protect workers from all RCS exposures above 50 µg/m3, which is the PEL as defined by OSHA. Under normal jobsite conditions, industrial hygiene testing conducted by a third-party, indicated that the sanding of Sheetrock® Brand ready-mixed joint compound, unless otherwise specified on packaging and within the SDS, does not contain RCS above the PEL.
What is the difference between labels on packaging and job site requirements?
OSHA’s Global Harmonization Standard (GHS) covers global hazardous material warnings on packaging. RCS is covered within the OSHA Hazard Communication Standard (2012), which is a job site regulation. The key difference between GHS and the new RCS regulation is that contractors are responsible for jobsite conditions, regardless of manufacturer packaging and/or SDS literature.
Does silica free joint compound exist?
There are no ready-mixed joint compounds that exist that are 100% “silica free.” However, the amount of respirable crystalline silica in USG joint compounds is low.
Does silica exist in USG Ready-Mixed Joint Compounds?
RCS is a natural impurity in the raw materials used to manufacture USG ready-mixed joint compound, and varies by product, depending on product formulation and raw material source. If RCS is present, it will be indicated in Section 3 of the Safety Data Sheet (SDS), as required by OSHA.
What do contractors need to do to comply with the new OSHA Silica Rules?
Does USG have a low dust joint compound?
Yes. USG Sheetrock® Brand Dust Control Joint Compound (www.usg.com/dustcontrol) was specially formulated to reduce airborne dust. Under NIOSH and OSHA guidance, this technology is considered an engineering control. However, you are still responsible for maintaining jobsite conditions and compliance with the new silica rule.
