Use of NIOSH-approved respirators only Evaluation of hazards Availability of multiple respirator types

11006115 Copyright 1999 Business and Legal Reports, Inc.

Respirators for Non-IDLH Use

If cartridges have no “end of service life indicator” a change schedule must be used

Added table for oxygen-deficient atmospheres based on altitude

11006115 Copyright 1999 Business and Legal Reports, Inc.

Medical Evaluation

Use of medical questionnaire (Appendix C) Follow-up medical exam for any positive

response to questionnaire All medical evaluations must be made

confidentially Employees must be allowed to discuss

the questionnaire with the physician

11006115 Copyright 1999 Business and Legal Reports, Inc.

Medical Evaluation (cont.)

Physicians must be told conditions of respirator use

Follow-up evaluations must be conducted if conditions of use or user health change

11006115 Copyright 1999 Business and Legal Reports, Inc.

Fit-Testing

Respirators will not protect you if they don’t fit properly!

Required for negative or positive pressure tight-fitting face pieces

Must be conducted prior to use Must be conducted at least annually Must be retested if respirator fit or

wearer change
