Intent	Intent 1: To limit the probability that deficiencies in systems for control of smoke movement and mechanical venting will go unnoticed, which could lead to such systems not operating as originally intended in a fire situation, which could lead to the buildup of smoke on floor areas or in exit stair shafts, 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 delays in evacuation or moving to a safe place, which could lead to harm to persons.
