1.Building characteristics, such as number of stories above or below grade plane, floor area, type of construction and fire-resistance of the primary structural frame to allow sustained fire-fighting operations based on a rating of not less than 2 hours.
2.Special hazards, other than buildings, that require unique accommodations to allow the fire department to replenish fire fighter breathing air.
3.Fire department staffing level.
