Unvented room heaters are prohibited in which occupancy groups?

Unvented room heaters are prohibited in specific occupancy groups primarily due to safety concerns related to the potential buildup of harmful gases like carbon monoxide in enclosed spaces. In the context of the options provided, occupancy groups A, E, and I represent specific types of buildings and uses where the risk associated with unvented heaters is significant.

Group A encompasses assembly spaces such as theaters and auditoriums, where large numbers of people gather. The safety of occupants in these environments is crucial, and the introduction of unvented heaters could lead to health risks if ventilation is inadequate.

Group E represents educational facilities, including schools and daycare centers. The well-being and safety of children and staff are paramount, thus making the use of unvented heaters inappropriate in these settings.

Group I includes institutions like hospitals and correctional facilities. The presence of vulnerable populations requiring a controlled and safe environment means strict regulations are in place regarding heating equipment, thus prohibiting unvented heaters.

Due to these considerations, unvented room heaters are restricted in occupancy groups A, E, and I to ensure the safety and health of individuals in these environments.
