Question: Not all students in the #7600 class will have obtained medical clearance to wear an air-purifying respirator. How can the 'Respiratory Protection PerformanceTest' be accomplished for these students?

Answer:

For any trainee who does not have documented medical clearance to wear an air-purifying respirator, the performance test can be performed with the removal of the cartridges/filter elements from the respirator facepiece after step 4 on the checklist. Step 9, the negative pressure user seal check, will be performed by placing the palms of the hands over the inhalation valve inlets and inhaling slightly for a count of 10.
