To quickly and effectively don a WWII-era gas mask, the key is swift and decisive action: throw your chin forward, insert it firmly into the mask, and pull the elastic straps over your head until the central tape is tight.
While the specific design varied slightly depending on the country issuing the mask, the core principles of application remained consistent across WWII. Speed was paramount, as exposure to chemical weapons could be fatal within minutes.
Here's a breakdown of the general procedure based on available instructions:
-
Alert and Ready: Be aware of any gas alarm or warning signs. Have your gas mask readily accessible, usually carried in a container on your person.
-
Prepare the Mask: Ensure the mask is properly oriented. Usually, the exhale valve is located on the front of the mask.
-
Chin First: Throw your chin well forward and aim to insert it deeply into the bottom of the mask. This is crucial for achieving a proper seal.
-
Secure the Straps: Simultaneously pull the elastic straps over your head as far as they will go. The goal is a snug, even fit. On some masks, a central tape or strap will need to be tightened last. Aim for tightness, but don't restrict breathing.
-
Check the Seal: Once the mask is on, quickly check for a proper seal around your face. A good seal prevents gas from entering. You can often do this by attempting to inhale; if the mask pulls firmly against your face, the seal is likely good. If you feel air leaking, readjust the mask immediately.
-
Exhale Vigorously: Exhale sharply to ensure the exhalation valve is functioning properly.
Important Considerations:
- Practice: Regular practice was crucial to ensure soldiers and civilians could don their masks quickly under pressure.
- Facial Hair: Beards and mustaches could compromise the seal of the mask. Regulations often required clean-shaven faces.
- Mask Condition: Regularly inspect your mask for damage and ensure the filter is in good working order. Damaged masks offer little to no protection.
- Children's Masks: Special, smaller masks were produced for children. The principles of application remained the same, but care was required to ensure a proper fit.
