What is the recommended first step for building managers during a bomb threat?

The recommended first step for building managers during a bomb threat is to notify a supervisor and then call the police. This approach is vital because it ensures that the appropriate authorities are informed immediately, allowing for a coordinated response to the potential threat. The police have the expertise and resources necessary to investigate the situation properly and determine if an evacuation or other action is required.

Notifying a supervisor is also crucial, as they can assist in managing the situation and ensuring that all communication is clear and thorough. Coordination within the management team allows for a unified response plan, which is essential during emergencies.

Increasing security throughout the building or contacting the fire safety director might be necessary later in the process; however, those steps would not address the immediate need for law enforcement involvement and quick decision-making regarding the safety of occupants. Posting emergency exit signs is a standard safety practice but does not directly relate to the immediate actions required during a bomb threat.
