Abstract:
"Gas mask phobia," a form of claustrophobia, impacts the ability of many service members to perform their mission. Historically, some soldiers have not donned, or quickly removed, their personal protective respirators because of discomfort, ignorance, or shame. Traditionally, little attention has been paid to this as a readiness issue. Exact numbers of service members who are unable to tolerate their masks are unknown. This phobia can be avoided with adequate training and treated with principles of desensitization, but more research is needed in early identification and treatment.
