Objective

OS1 Fire Safety

Attribution

Intent

Intent 1:

To exempt openings for escalators and inclined moving walks from the requirements of Articles 3.2.8.3. to 3.2.8.8., which would otherwise require certain fire protection measures, if:

  • the size of the openings is limited,
  • the building is sprinklered throughout, and
  • the interconnected floor space contains only certain major occupancies.

This is to limit the probability that:

  • large openings will permit the spread of fire to other parts of the building,
  • a fire will not be controlled or suppressed, which could lead to the spread of fire through the openings, and
  • fire hazards [from the type of occupancy] will not be minimized, which could lead to the start and spread of fire through the openings.

This is to limit the probability of harm to persons.
