Tests show problems with firefighter radios

摘要

Washington - Portable radios used by firefighters may fail when exposed to high temperatures, putting firefighters at risk, according to the National Institute of Standards and Technology. NIST recently announced test results that identified potential safety hazards for firefighters who use portable radios. All seven radios tested by NIST failed within 15 minutes when subjected to a temperature of 320° F, which represents the conditions of a fully involved fire.
