FIT TESTING
Any respirator with a tight fitting facepiece may not be assigned until the user is given a qualitative or quantitative respirator fit test
and the results of the test indicate that the facepiece of the respirator fits that person properly. The RU6500 Series is available in
three sizes. The letters "S", "M" or "L" on the face seal indicate sizes Small, Medium, or Large. See instructions below for putting
on the respirator. Refer to the most recent OSHA 29 CFR 1910.134 Appendix A (USA), CSA Z 94 (Canada), AS/NZS 1715 for
specific Fit Test procedures (Australia and New Zealand), or Brazilian MTE Respiratory Protection Program.
