SCBA stands for?

• A. Self-Contained Breathing Apparatus
• B. Single-Containment Breathing Air
• C. Self-Contained Breathing Assist
• D. Systematic Contained Breathing Apparatus

Answer: (A)

SCBA stands for Self-Contained Breathing Apparatus. The phrase “self-contained” means the user carries the air supply on the device itself (in a cylinder or tank), rather than relying on ambient air or a plant/main supply. “Breathing apparatus” is the equipment that delivers that air to the user, typically including a mask and the carrying cylinder, so the wearer can breathe safely in hazardous environments like smoke, toxic gases, or oxygen-deficient atmospheres. The other options don’t reflect established terminology: they describe nonstandard terms or imply assistance rather than a complete, portable air supply.
