To properly put on a respirator, particularly a full-face type as shown in the reference, follow these key steps for a secure fit. Getting the correct fit is crucial for ensuring the respirator provides the intended protection.
Steps for Donning a Respirator
Putting on a respirator involves carefully positioning it and securing the head harness to create a tight seal against your face.
Here is a breakdown of the process:
- Hold to Face: Begin by holding the respirator firmly against your face, ensuring the chin cup (if applicable) is in place and the mask covers your mouth and nose.
- Grab Head Harness: With the respirator held in position, reach back and grasp the head harness assembly.
- Pull Over Head: Pull the head harness up and over the back of your head. Position the harness so that it rests comfortably, typically high on the back of the head.
- Tighten Straps: Once the harness is in place, you will need to tighten the straps to achieve a secure seal. Begin tightening the lower, neck straps first.
- Tighten Temple Straps: After tightening the neck straps, proceed to tighten the upper, or temple, straps. Tighten all straps evenly to avoid pressure points and ensure the mask seals properly around the face.
(Based on reference: Pull [head harness] over your. Head begin to tighten the straps neck straps first followed by temple straps.)
Why Proper Strap Tightening Matters
Tightening the straps in the correct sequence helps to pull the respirator down and back onto the face evenly. Starting with the lower straps anchors the mask at the bottom, allowing the upper straps to then complete the seal across the top and sides of the face without tilting the mask upwards.
Step-by-Step Overview
For clarity, here are the steps presented in a simple table format:
| Step | Action | Notes |
|---|---|---|
| 1. Position Mask | Hold the respirator securely against your face. | Ensure mouth and nose are covered, chin is in cup if available. |
| 2. Grasp Harness | Grab the head strap assembly behind the mask. | Prepare to pull it over your head. |
| 3. Pull Harness Over | Pull the head harness up and over the back of your head. | Position it comfortably and high on the back of your head. |
| 4. Tighten Neck Straps | Tighten the lower straps originating from the neck/chin area first. | Pull straps until snug, but not overly tight. |
| 5. Tighten Temple Straps | Tighten the upper straps originating from the temple/cheek area next. | Pull straps until the mask feels secure and seals against the face. |
Remember to perform a user seal check after putting on the respirator to confirm that you have achieved a proper seal before entering a hazardous environment.
