If all fire doors in a banquet hall are locked, what should the security guard do?

The situation at hand involves a critical safety issue. If all fire doors in a banquet hall are locked, this compromises the safety of all individuals within the space. In an emergency, particularly a fire, these doors exist to provide a safe exit to ensure that people can evacuate swiftly. The appropriate response is to refuse to work under these conditions and contact the fire department. This is essential because the fire department has the authority and capability to address the violation of safety regulations, ensuring the environment conforms to fire safety codes.

This action serves to protect the attendees and reinforces the importance of adhering to safety protocols, as a locked fire exit can lead to disastrous outcomes during an emergency. It's critical for security personnel to prioritize life safety over their immediate work requirements when faced with such significant risks.
