MOSH Standards Notice 07-2 - Maryland Occupational Safety and Health (MOSH)

 
TO: All MOSH Personnel
 
FROM: Roger Campbell, Assistant Commissioner
 
SUBJECT: Revisions relating to Assigned Protection Factors, 29 CFR Parts 1910 and 1926.
 
PURPOSE: To revise the existing Respiratory Protection Standard to add definitions and requirements for Assigned Protection Factors (APFs) and Maximum Use Concentrations (MUCs). The revisions also supersede the current respirator selection provisions of existing substance-specific standards with new APFs, except for the respirator selection provisions of the 1.3 Butadiene Standard.

The final APFs provide employers with critical information to use when selecting respirators for employees exposed to atmospheric contaminants in construction and general industry workplaces. Proper respirator selection using APFs is an important component of an effective respiratory protection program.

Employers also use MUCs to select appropriate respirators, especially for protection against organic vapors and gases. MUCs specify the maximum atmospheric concentrations that an employee can experience while wearing a specific respirator or class of respirator.
 
EFFECTIVE DATE: April 9, 2007
 
ISSUANCE DATE: February 20, 2008
