Which code signals a life-threatening emergency?

• A. Code Red
• B. Code Brown
• C. Code Adam
• D. Code Silver

Answer: (A)

Code Red signals a fire or dangerous smoke, creating an immediate life-threatening situation for everyone in the building. When Code Red is announced, follow fire safety procedures right away: evacuate if instructed, or shelter in place as directed, pull the fire alarm, call emergency services, and close doors to contain the fire and slow its spread. Other codes refer to different situations—hazardous spills call for containment, a missing child requires a security alert, and an active shooter requires lockdown or rapid sheltering. None of those emergency scenarios demand the same rapid, building-wide evacuation response that a fire emergency does, so Code Red is the one that most directly represents a life-threatening risk to occupants.
