Do you all kno Anyone know what I'm talking about--- that has had some military training and hence can help me illustrate this important concept?
I've been scavenging through a whole pile of A4 handouts but I can't seem to turn anything up on the subject. I have since started trudging through the online archives to find a pam of some sort.
http://www.gasmasks.net/ is an almost fetish level enthusiastic site
http://www.globalsecurity.org/wmd/library/...-100/index.html (http://www.globalsecurity.org/wmd/library/policy/army/fm/3-100/index.html) is the index page to a pam produced by the U.S Army on Nuclear, Biological and Chemical warfare. It ofcoarse doesn't show you how to do it.....
Lets cut and paste frome somewhere else.....
the following steps outline the procedure for
properly fitting the protective mask:
1. Let the harness straps out to their full ength.
2. Don the mask by inserting your chin in the lower end of the facepiece and pulling the head harness over your head.
3. While holding the head harness pad against the center of the back of your head, pull back on the Top strap tab until the mask rests lightly under your chin.
4. Pull back on the two side strap tabs until the upper sides of the mask rest lightly against your face.
5. Pull back on the bottom strap tabs until the lower sides of the mask rest lightly against your face.
6. Check the mask for an airtight seal by placing your hands over the canisters so that no air can enter and by inhaling normally until the mask collapses. Hold your breath for about 10 seconds to see if the mask remains collapsed. If the mask does not collapse, or does not remain Figure 6-3.-Securing the top and side straps for permanent fit. collapsed, the mask is defective or the straps are not properly adjusted. NOTE: A leakproof fit cannot be expected unless the wearer is smooth shaven. After the foregoing tests have been made and the strap adjustments are correct, adjust the top and side straps for a permanent fit. Permanently fit the mask by threading the loose ends of the
top and side straps through the buckles between the body and the sliding member, as shown in figure 6-3. These straps will then be permanently adjusted to the individual. Only the two bottom
straps will have to be loosened each time the mask is removed or donned. Both the mask and the
carrier should be securely marked with the name of the person on whom the mask has been fitted.
DONNING THE ND MK V MASK. —To train your personnel in the proper procedures for donning and removing the mask, you should conduct periodic drills. During these drills, you should emphasize speed as well as accuracy in donning the mask. The general procedures for donning and removing the mask are as follows:
At the command “GAS,” take the following
actions
1. Stop breathing and remove your headgear.
2. Yank open the carrier flap and remove the
mask from the carrier.
3. Insert your thumbs under the head harness straps and grasp the top of the facepiece.
4. Raise the mask to your outthrust chin and bring the head harness over the back of your head.
5.Center the head harness pad on the back of your head and adjust the bottom straps as necessary for proper fit.
6. Close the outlet valve with the heel of the hand and exhale forcibly to clear the mask of contaminated air.
7. Test the mask for possible leakage by placing your palms over the canisters and inhaling normally until the mask collapses against your face and remains collapsed for approximately 10 seconds.
Resume normal breathing.
8.Replace headgear and close the carrier flap. The protective mask outlet valve sometimes sticks closed because saliva or sweat has dried on it. If this occurs, you may loosen the valve by blowing into the valve or by massaging the valve. The valve may be massaged with the valve cover
partially removed as shown in figure 6-4.
