Which is NOT listed as an SCBA limitation?

• A. Limitation of Air supply
• B. Limitation of the Wearer
• C. Limitation of Equipment
• D. Limitation of Visibility

Answer: (D)

The main idea here is how SCBA use is categorized in terms of what can limit it. In standard fire service training, the three formal limitations are tied to the air supply, the wearer, and the equipment. Air supply limitation is about how long the cylinder lasts and how air use is managed during a task. Limitation of the wearer covers the physical demands, fit, mobility, and endurance of the person wearing the SCBA. Limitation of equipment includes potential failures or reliability issues with the SCBA components, like regulators, gauges, alarms, or hoses.

Limitation of Visibility isn’t typically listed as one of these formal SCBA limitation categories. Visibility can be affected by the environment or by fogging inside the facepiece, but it’s treated as an environmental condition or hazard rather than a core SCBA limitation category. That’s why it’s not included in the standard list of SCBA limitations.
