Question: A security guard is performing duties in a multi-story commercial building when a fire alarm activates on the fifth floor. Upon investigation, the guard observes light smoke emanating from a closed office door. There are no immediate signs of active flames, but the alarm continues to sound. Which of the following is the most appropriate initial action for the security guard to take, adhering to Canadian emergency response protocols?

Answer options:

• Immediately activate the building's public address system to initiate a full building evacuation while simultaneously attempting to locate the source of the smoke.
• Proceed directly to the secured fire alarm panel to silence the alarm and then contact building management for further instructions. ✅ Contact emergency services (e.g., 911), confine the smoke by ensuring the office door remains closed, and begin directing occupants away from the immediate area.
• Investigate the specific office by carefully opening the door to assess the severity of the fire before making any external notifications.

Correct answer: Contact emergency services (e.g., 911), confine the smoke by ensuring the office door remains closed, and begin directing occupants away from the immediate area.

Explanation: In Canada, security guards are trained to prioritize life safety. Confining the smoke and immediately contacting emergency services like 911 are critical first steps, as per fire safety plans and provincial fire codes, while also commencing preliminary evacuation of the immediate danger zone.
