Explanation:

• Question 18: A decon corridor is used as a gateway from the hazard area to rehab in incidents involving exposure to potentially hazardous substances. A medical tent is for medical treatment, a changing station is for changing clothes, and an evacuation corridor is for evacuating people.
• Question 19: When cleaning and sanitizing SCBA, personnel should dry the facepiece with a lint - free cloth or air dry it. Paper towels can leave lint, hot water can damage components, and regulators and low - pressure hoses should not be washed in warm water in the way described.
• Question 20: Firefighter breathing air replenishment systems (FBARS) are designed to refill air cylinders in a cascade or auto - cascade system. They are not specifically for fire stations, high - rise buildings, or wildland fire response in the context of their main design for refilling.

1. B. decon corridor
2. B. dry the facepiece with a lint - free cloth or air dry it
3. D. in a cascade or auto - cascade system
