Dear Mr. Rawles-
I am writing to tell other Survival Blog readers about a recent experience I had with an N95 mask (with no exhalation port.) My husband and I just bought a 30 year old single wide trailer with 30 years worth of dust, mold, and cat hair. After day of being in the trailer I could feel my allergies start to grow worse by the minute. To clean up the dust, cat hair, and other allergens we went to the local hardware store and rented a Rug Doctor to shampoo the carpets. While shampooing the carpets (which was a bit labor intensive) I wore an N95 mask and let me tell ya’ it was an experience. After 30 minutes I felt like I was breathing in thick jungle air. After one hour I felt like I was going to pass out. After two hours I began to feel claustrophobic. If there are readers out there who think they are going to throw on an N95 mask when the swine flu hits their area and run from room to room while caring for sick and dying relatives/friends they better think again. My suggestion is to put on an N95 mask this afternoon, mow the lawn, rake some leaves, take the dog for a brisk walk and see how you feel afterwards. Having survival gear is great but if you have no real world experience with it then it’s useless. Know your personal limitations and the limitations of your gear. God bless!
More prepped than ever for the swine flu, – Heather
JWR Replies: In my experience, it takes time to acclimate to wearing a respirator mask. There is no substitute for hours in a mask. Particularly for a full-face military mask, and even more so for a full MOPP suit, limited field of vision, dehydration, claustrophobia and sensory deprivation are well-known effects, but heat build-up up is also an issue, particularly in summer weather. In full-face masks, being deprived of prescription lenses is also an issue, unless you have a prescription lens inserts. (BTW, these hard-to-find inserts are available from JRH Enterprises.) Also be particularly wary of dehydration. Even with masks that include a drinking tube, most wearers have a tendency to drink less than usual.
The bottom line: Practice wearing a mask regularly, in a variety of activities.
