Final answer:
No singular correct answer exists for how many people should be responsible for fire reporting and emergency response in an office, but at least a primary and a backup person is recommended for effectiveness and continuous coverage.
Step-by-step explanation:
When considering the number of people who should be designated responsible for reporting a fire and overseeing the office's emergency response, there isn't a universally correct answer as it can depend on various factors such as the size of the office, the layout, and existing emergency protocols. Generally, it's critical to have a comprehensive emergency plan in place, which includes the designation of responsible personnel for reporting fires and managing the response. There should be at least one primary person assigned to this role, but it is also wise to have backup individuals in case the primary is unavailable. In many cases, depending on the complexity and size of the office, having two people designated — a primary and a secondary — can ensure continuous coverage and an effective emergency response.
