What signal code must be used when an alarm is activated at a facility storing highly sensitive materials?

The signal code used when an alarm is activated at a facility storing highly sensitive materials is 10-13. This code is designated specifically for situations involving hazardous materials, ensuring that the nature of the alarm is communicated clearly to responding units. Utilizing this code alerts first responders to approach the situation with the necessary precautions due to the potential dangers associated with sensitive materials, which may include hazardous chemicals or biologically dangerous substances.

When 10-13 is transmitted, it helps in coordinating an appropriate response by providing essential information to all personnel involved, ensuring their safety and the effective handling of the incident. This is crucial for maintaining a structured communication protocol within the police department, which aims to enhance operational efficiency and safety during emergencies that involve sensitive or hazardous materials.
