OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at http://www.osha.gov.

MEMORANDUM FOR: REGIONAL ADMINISTRATORS
FROM: RICHARD E. FAIRFAX
DIRECTOR
DIRECTORATE OF COMPLIANCE PROGRAMS
SUBJECT: Misprint of the Respirator Section of the Methylene
Chloride Standard in the 1998 Edition of the Code of
Federal Regulations

The 1998 edition of the Code of Federal Regulations (published in July) mistakenly contains two respiratory protection sections for the methylene chloride standard, 29 CFR 1910.1052. The first section, beginning on page 435 at (g)(1) and ending on page 436 at (g)(4)(ii), is correct and is the section to enforce. The second respiratory protection section, beginning on page 436 at (g)(1) and ending on page 437 at (g)(7)(ii), is incorrect and should be disregarded.

The methylene chloride standard on the Occupational Safety and Health Administration's (OSHA's) world wide web site (www.osha.gov) contains only the correct version of the respiratory protection section.

Please distribute this memorandum to the Area Offices and the State designees in your Region.
