Frequently Asked Questions About Petroleum distillates (Naphtha) (Rubber Solvent) Exposure

What is the legal OSHA PEL for Petroleum distillates (Naphtha) (Rubber Solvent)?

Under OSHA 29 CFR 1910.1000 Table Z-1, the 8-hour Time-Weighted Average (TWA) Permissible Exposure Limit (PEL) for Petroleum distillates (Naphtha) (Rubber Solvent) (CAS N/A) is 500 ppm. In addition, NIOSH recommends a Recommended Exposure Limit (REL) of 350 ppm.

How do extended 10-hour and 12-hour shifts affect Petroleum distillates (Naphtha) (Rubber Solvent) exposure limits?

Because OSHA PELs are formulated for 8-hour workdays, working 10-hour or 12-hour shifts reduces recovery time. Applying the standard Brief & Scala mathematical model reduces the allowable concentration by a Reduction Factor (RF = 0.700 for 10-hr, RF = 0.500 for 12-hr). For Petroleum distillates (Naphtha) (Rubber Solvent), an 8-hr PEL of 500 ppm adjusts to half that value on a 12-hour shift.

What respirator and PPE is required when handling Petroleum distillates (Naphtha) (Rubber Solvent)?

When atmospheric concentrations exceed the permissible limit up to 10× PEL, OSHA 29 CFR 1910.134 mandates a half-mask elastomeric respirator equipped with Organic Vapor (Black). For dermal exposure, Viton or Silver Shield / 4H are recommended.

What is the IDLH threshold for Petroleum distillates (Naphtha) (Rubber Solvent)?

The Immediately Dangerous to Life or Health (IDLH) concentration established by NIOSH for Petroleum distillates (Naphtha) (Rubber Solvent) is 5000 ppm. Any entry into atmospheres at or above this concentration requires positive-pressure supplied air or Self-Contained Breathing Apparatus (SCBA).
