What is hydrogen cyanide?
formed when plastic products burn, quickly absorbed by blood and interferes with cellular respiration, small amount = unconscious
incomplete combustion of many household products including vinyl, effects at low level: itchy throat and eyes. High levels: pulmonary edema. WWI weapon

SCBA's typically used for structure fire
used for extended operations: mine rescue work, long tunnels, etc
what is a SAR?
supplied air respirator: uses external source for breathing air. Uses a one way valve just like open circuit SCBA (common in industrial setting) sometimes used by tech rescue teams
