Which action is unsafe when handling oxygen?

• A. Check for kinks in tubing
• B. Light matches near the oxygen tank
• C. Check water level in the humidity bottle
• D. Ensure oxygen is flowing

Answer: (B)

Oxygen-rich environments ignite more easily because oxygen supports and speeds up combustion. Lighting a flame near an oxygen tank is dangerous because it can cause flames to flare up quickly, ignite equipment or clothing, and even damage the tank. That is why this action is unsafe. The other steps—checking tubing for kinks to ensure proper delivery, checking the water level in the humidity bottle for patient comfort and system function, and confirming that oxygen is flowing to provide the prescribed therapy—are safety-focused and do not introduce an open flame.
