Intent 1:
To exempt openings for escalators and inclined moving
walks from the requirements of Articles 3.2.8.3. to 3.2.8.9., 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.
