||Should helicopter frequent flyers wear head protection? A study of helmet effectiveness
||July 1991, Vol.33, No.7, p.766-769. Illus. 21 ref.
||Flight helmets have been recommended as aircrew head protection since 1908, yet debate continues regarding their effectiveness. Estimates of helmet use in civilian helicopter aeromedical programmes range from 6.5% to 13%. The effectiveness of the US Army's SPH-4 flight helmet in reducing severe head injuries sustained during helicopter accidents was evaluated using the accident data base at the US Army Safety Center, Fort Rucker, Alabama. Analysis was restricted to severe (Class A) accidents that were at least partially survivable, using US Army Center criteria. Occupants not wearing a protective helmet were significantly more likely to sustain severe and fatal head injuries than were occupants wearing the SPH-4 (RR=3.8 and 6.3, respectively; p<.01). Unhelmeted noncockpit occupants were at higher risk of head injuries (RR=5.3 and 7.5; p<.01). All personnel regularly participating in helicopter flight, civilian or military, should be equipped with protective headgear.
