A Report on the Performance of Firefighters' Helmets.

PB274223

Publication Date	1976
Personal Author	Cook, W. I.
Page Count	44
Abstract	Samples of 8 models of firefighters' helmets are evaluated and tested for conformance to American National Standards Institute standard Z89.1-1969. The impact tests are performed using both the standard method and an electronic force measurement system, and the two force measurement methods are compared. Four of the 8 models tested are in conformance with performance requirements. Based on available information on the characteristics of plastics at temperatures in the vicinity of 300 degrees Fahrenheit, it is recommended that users expecting to work in such environments require impact testing on helmets conditioned at a temperature of at least 300 degrees for at least 3 minutes.
