Explanation
According to NFPA 101: Life Safety Code, 2018 Edition, the travel distance limit for a new unsprinklered educational occupancy is 175 ft. (53 m). This is the maximum distance that an occupant has to travel from any point within the building to reach an exit or exit access door. The travel distance limit for a new sprinklered educational occupancy is 250 ft. (76 m).These limits are based on the assumption that the building has at least two exits or exit access doors from each room or space12 References:
