Frequently Asked Questions About Sodium fluoroacetate Exposure

What is the legal OSHA PEL for Sodium fluoroacetate?

Under OSHA 29 CFR 1910.1000 Table Z-1, the 8-hour Time-Weighted Average (TWA) Permissible Exposure Limit (PEL) for Sodium fluoroacetate (CAS 62-74-8) is 0.05 mg/m³. In addition, NIOSH recommends a Recommended Exposure Limit (REL) of 0.05 ppm.

How do extended 10-hour and 12-hour shifts affect Sodium fluoroacetate 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 Sodium fluoroacetate, an 8-hr PEL of 0.05 mg/m³ adjusts to half that value on a 12-hour shift.

What respirator and PPE is required when handling Sodium fluoroacetate?

When atmospheric concentrations exceed the permissible limit up to 10× PEL, OSHA 29 CFR 1910.134 mandates a half-mask elastomeric respirator equipped with Acid Gas (Yellow/White). For dermal exposure, Nitrile or Neoprene Chemical Barrier are recommended.

What is the IDLH threshold for Sodium fluoroacetate?

The Immediately Dangerous to Life or Health (IDLH) concentration established by NIOSH for Sodium fluoroacetate is 0.5 ppm. Any entry into atmospheres at or above this concentration requires positive-pressure supplied air or Self-Contained Breathing Apparatus (SCBA).
