You are alone in zero-visibility conditions and unable to find an exit. Which action listed below should you take first?

• A. Activate your personal alert safety system (PASS)
• B. Attempt to find a hose line or tagline
• C. Declare a "mayday" over your radio
• D. Find a wall and methodically search it for a window or door

Answer: (C)

In zero visibility with no exit in sight, the immediate priority is to summon rescuers. Declaring a mayday over your radio does exactly that: it immediately communicates that you’re in life-threatening trouble, triggers a formal rescue response, and provides your basic details and needs so incident command can start locating and extracting you. This swift communication keeps you connected to the larger rescue effort and helps prevent delays. Activating a personal alert safety system can help draw attention if you’re unable to speak or move, but it doesn’t guarantee that rescuers know where you are or what you need. Attempting to find a hose line or searching for a window or door relies on moving and orienting yourself in dangerous conditions, which can waste precious time and increase your risk. Looking for a wall to methodically search for an exit is similarly time-consuming and may lead you deeper into disorientation. So, calling for help right away is the best first step to maximize your chances of rapid rescue.
