Final answer:
Coordinators of fire safety and alarm systems in homeless shelters are specifically required in D) Homeless shelters. While other building types also follow strict building codes, homeless shelters have additional safety regulations unique to their occupancy type.
Step-by-step explanation:
In what types of buildings and occupancies are coordinators of fire safety and alarm systems in homeless shelters required? The specific type of building where a coordinator of fire safety and alarm systems would be necessary is D) Homeless shelters. While other types of buildings, such as residential buildings, commercial buildings, and industrial buildings, are also subject to strict building codes to ensure the safety of occupants, the mention of a homeless shelter in the question implies that the answer should be specific to this type of occupancy. Building codes in many developed countries (MDCs) mandate comprehensive safety measures, including working ventilation and heating systems, structurally safe construction, smoke detectors, and properly installed electrical wiring.
Homeless shelters, being residential in nature but also serving a vulnerable segment of the population in a semi-institutional setting, often have additional regulations to ensure the safety and well-being of their occupants. Therefore, the implementation of fire safety and alarm systems coordinated by a designated professional is crucial and likely required by law in these facilities.
