Frequently Asked Questions About Dichloromethane; see Methylene chloride Exposure
What is the legal OSHA PEL for Dichloromethane; see Methylene chloride?
Under OSHA 29 CFR 1910.1000 Table Z-1, the 8-hour Time-Weighted Average (TWA) Permissible Exposure Limit (PEL) for Dichloromethane; see Methylene chloride (CAS N/A) is See Standard Table Z. In addition, NIOSH recommends a Recommended Exposure Limit (REL) of 0 ppm.
How do extended 10-hour and 12-hour shifts affect Dichloromethane; see Methylene chloride 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 Dichloromethane; see Methylene chloride, an 8-hr PEL of See Standard Table Z adjusts to half that value on a 12-hour shift.
What respirator and PPE is required when handling Dichloromethane; see Methylene chloride?
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 Dichloromethane; see Methylene chloride?
The Immediately Dangerous to Life or Health (IDLH) concentration established by NIOSH for Dichloromethane; see Methylene chloride is Not Listed. Any entry into atmospheres at or above this concentration requires positive-pressure supplied air or Self-Contained Breathing Apparatus (SCBA).
