Intent
Intent 1: 
To limit the probability that deficiencies in fire emergency systems will go unnoticed, which could lead to such systems not operating as originally intended in a fire situation, which could lead to:
  • delays or inefficiencies in emergency suppression operations, which could lead to the spread of fire, which could lead to harm to persons, including emergency responders,
  • delays or inefficiencies in emergency rescue operations, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons, including emergency responders,
  • the buildup of smoke on floor areas, which could lead to delays or inefficiencies in emergency suppression operations, which could lead to the spread of fire, which could lead to harm to persons, including emergency responders, and
  • the buildup of smoke on floor areas or in exit stair shafts, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.
