Orange County fire rescue meets the requirements for what grade air?

Explanation:
Breathing-air classifications show how clean and dry the air is for respirators. Grade D is the baseline minimum standard, while Grade E represents a higher-quality air with stricter limits on contaminants and moisture. Orange County fire rescue meeting Grade E requirements means their air supply from compressors and filters meets that tighter standard, making it suitable for firefighters in hazardous operations. That’s why Grade E is the best fit here, indicating better-than-minimum air quality appropriate for rescue work.
