PASS device… p194
PASS emits a loud alarm to alert other personnel that a firefighter is in danger.
The alarm activates when a firefighter has been motionless for 30 seconds or when a firefighter presses the emergency button. The alarm must be at least 95 decibels and must go off continually for one hour.
Oxygen deficiency… p202
NFPA and OSHA define an oxygen deficient environment as one containing less than 19.5% oxygen.
When oxygen levels fall below 18%, the human body increases its respiratory rate. As less oxygen reaches body tissues, hypoxia occurs.
How many decibels must the PASS be and how long must it alarm for continuously?
The alarm must be 95 dBA and must go off continuously for one hour.
At what temperature does the MSA facepiece fail at?
The facepiece will fail at 500f.
