 Naval Air Facility Masawa has to take important steps when staying vigilant against possible threats. NAF's Emergency Management Department protects sailors by providing the proper personal protective equipment to survive in environments that have been rendered toxic. Before any gear can be utilized, each sailor must first complete a mission-oriented protective posture gear fitting. We first start out by measuring just their boot size to make sure that they have the correct suit. And then as far as the mask goes, we'll use our mask leakage tester to make sure that everybody has the correct fit mask. In case we do happen to come under a CBR attack, this is very important. This will save your life. This will keep you from dying, from getting sick. After the initial fitting, members are required to refit annually to keep their file current.
