Final answer:
The correct answer is option 3) Building maintenance staff.The responsibility for maintaining the safety of a building's occupants by proper maintenance of fire protection systems falls on the building maintenance staff.
Step-by-step explanation:
It is the responsibility of the building maintenance staff to ensure the safety of all occupants by maintaining the fire protection system's integrity. This includes ensuring that all systems are regularly inspected, tested, and complying with safety regulations. Building maintenance staff are often trained in identifying and addressing issues related to system impairments, and they are crucial in facilitating repairs and improvements to protect the building's occupants from fire hazards.
Firefighters, like those described in the provided reference, are first responders who are trained to control and extinguish fires and to conduct rescue efforts once a fire has occurred. Security guards, while responsible for maintaining security, may not be trained in fire system maintenance. Occupants themselves can help by being aware of their surroundings and reporting potential hazards, but they are not typically qualified to maintain fire safety systems.
Moreover, under OSHA regulations, employers have the duty to provide a safe workplace, which includes proper fire safety measures. Enforcement of such safety standards may include audits and must prioritize preventing imminent dangers, which includes having a fully functional fire protection system.
