Intent

Intent 1:

To supersede the requirements of other provisions of the Code [typically Clause 3.6.2.7.(2)(b)] for the inclusion of sprinklers in an electrical vault located in a building that is otherwise sprinklered throughout, if certain conditions are met.

This is to limit the probability that:

  • other fire hazards will be present in the vault, which could lead to a fire involving the electrical equipment, which could lead to the spread of fire from the vault to other parts of the building, which could lead to harm to persons in other parts of the building,
  • smoke from a fire in the vault will not be promptly detected, which could lead to persons not being notified of the fire situation, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons, and
  • a fire originating in a location outside the vault will spread into the vault, which could lead to the disruption and discontinuation of service from equipment located in the vault, which could lead to an undue fire hazard in the building, which could lead to harm to persons.
