Help has arrived for companies to comply with the revisions to the federal respiratory standard.
OSHA has published a new guidance document, Assigned Protection Factors.
In 2006, OSHA revised its Respiratory Protection Standard to add Assigned Protection Factors (APFs) and Maximum Use Concentration (MUC) provisions.
APF means the workplace level of protection that a respirator or class of respirators provides to workers. The higher the APF (5 to 10,000), the greater the protection.
MUC represents the limit at which the class of respirator is expected to provide protection.
The OSHA guide includes a new APF table, information on how to use APFs and MUCs, and the text of the Respiratory Protection Standard.
