Essential Respirator Safety: Medical Evaluation and Fit Testing Guide

This guide outlines the critical requirements for employees who need to wear respirators. Before using a respirator, employees must complete a medical evaluation reviewed by a company doctor to determine their fitness for use. Mandatory positive and negative pressure seal checks should be conducted every time the respirator is donned to ensure an effective fit. Regular maintenance, including inspection, cleaning, and proper storage of respirators, is crucial for safety. These procedures should be followed diligently to guarantee the effectiveness of respiratory protection.

  1. Respiratory Program

  2. Medical Requirements • Every employee that is required to wear a respirator will fill out a medical evaluation. • The company doctor will review the medical evaluation and determine if the employee is capable of wearing a respirator.

  3. Positive and Negative Pressure Seal Check • A positive and negative fit test must be performed each time the respirator is put on. • Be sure to perform the test before entering the hazardous atmosphere.

  4. Positive Pressure Seal Check 1. Block off the exhalation valve with your palm 2. Blow out gently 3. If no leaks are detected you have a good fit 4. If leaks are detected adjust the face piece and test again.

  5. Negative Pressure Seal Check 1. Place your palms over the inhalation inlets 2. Inhale gently so the face piece collapses slightly 3. Hold breath for ten seconds 4. If the face piece holds the negative pressure you have a good fit 5. If the face piece looses the pressure, adjust the face piece and test again

  6. Maintenance The three steps to maintenance 1. Inspection 2. Cleaning 3. Storage

  7. Inspection • Check for the following: 1. Holes in filters 2. Loss of elasticity 3. Tears 4. Broken or loose connections 5. Missing parts 6. General cleanliness

  8. Cleaning 1. Remove filters 2. Disassemble face piece 3. Discard defective parts 4. Wash in warm water 5. Rinse thoroughly 6. Disinfect 7. Reassemble

  9. Storage 1. Respirators must be stored in a sealed, labeled, plastic bag • Keep respirator away from chemicals, moisture, cold, heat, dust, and sunlight

  10. 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 changes
