Firefighters' SCBA: belt radiant heat resistance.
NIOSH 1980 Sep; :1-33
Belts of firefighters' self contained breathing apparatus (SCBA) were analysed for heat resistance. Elongation and stiffness were measured at heat intensities of 0.43, 0.92, and 1.16 watts per square centimeter. A simulated environment was achieved by keeping belts under tension against a backing under heat. Typical belt survival times ranged from 4.49 minutes for survivor belts to 0.80 minutes for Scott belts. The performance of several currently used SCBA belts in a high radiation environment was discussed. The author recommends the development of belt standards.
