In order to safely conduct a primary search, rescuers should:

• A. Work alone
• B. Not communicate
• C. Work in teams of two or more
• D. Wear no SCBA

Answer: (C)

The safety principle in a primary search is to operate with a buddy system and clear coordination. Rescuers should not work alone; having two or more people ensures mutual support, accountability, and a reliable way to relay information and respond to changes in the environment. In practice, teams of two or more can divide tasks, monitor each other for signs of distress, and rapidly assist or evacuate a teammate if needed. This collaborative approach also makes it possible to maintain line-of-sight communication and verify locations as the search progresses.

In hazardous environments, protective gear is essential, and wearing a self-contained breathing apparatus (SCBA) is a critical part of staying safe when air quality is uncertain or compromised. Choosing not to wear SCBA in such conditions dramatically increases the risk of inhalation hazards or oxygen deficiency.

So, the best practice is to work in teams of two or more, with continuous communication and appropriate PPE, to maximize safety and effectiveness during a primary search.
