Performance Evaluation of DM and DFM Filter Respirators—WORKING DRAFT 9.15.92
  • Almost 80% of negative-pressure respirator wearers were not receiving fit testing.[1]
  • Over 70% of 123,000 manufacturing plants did not perform exposure-level monitoring, when selecting respirators to use in the plants.[2] The level of noncompliance increased to almost 90% for the smallest plants.
  • 75% of manufacturing plants did not have a written program.[3]
  • 56% of manufacturing plants did not have a professional respirator-program administrator (i.e., qualified individual supervising the program).[4]
  • almost 50% of wearers in manufacturing plants did not receive an annual examination by a physician.[5]
  • almost 50% of wearers in manufacturing plants did not receive respirator-use training.[6]
  • 80% of wearers in manufacturing plants did not have access to more than one facial-size mask, even though nearly all reusable masks were available in at least three sizes.

Additionally, Hyatt had noted earlier in 1976 that:

The majority of those purchasing and using respirators do not conduct a fitting program to determine if the respirator provides an adequate face seal.[7]
