Protecting an injured or incapacitated individual in a hazardous environment depends on the rapid and correct application of a gas mask. Understanding the specific steps for assisting someone else is vital.
Putting a gas mask on an injured person differs from self-application as it requires positioning and careful handling of another individual. Based on guidance for assisting a wounded person, here are the key steps:
Proper Positioning is Crucial
One of the most important initial steps, as highlighted in the reference, is the need for turning the person on their back. This position is crucial as it facilitates access and helps stabilize the individual while you apply the mask. Remember the need for turning the person on their back.
Applying and Securing the Mask
While the reference focuses on positioning and sealing, the general process of applying the mask when assisting someone typically involves:
- Preparing the mask: Ensure the filter is securely attached and the mask is ready for use.
- Placing on face: Position the mask over the person's face, guiding their chin into the mask's chin cup to ensure a foundational fit.
- Pulling the harness: Bring the head harness over the back of their head.
- Adjusting straps: Tighten the straps evenly to achieve a snug, but not overly tight, seal against the face, working from the lower straps upwards.
Verifying the Seal
Once the mask is on, it is essential to test whether the mask is sealing correctly. The reference notes this step is critical, even mentioning testing on a person who is conscious but faking unconsciousness, implying the seal check is necessary regardless of the person's responsiveness or perceived state. This verification ensures that no hazardous substances can bypass the mask's filter.
Why Seal Checks Matter
A proper seal is the barrier that prevents contaminated air from entering the mask. A successful seal check confirms that the mask is fitted correctly and is providing the intended protection.
