- DEnsuring the salon's HVAC system is set to recirculate air.
Show answer & explanationAnswer & explanation
Correct answer: B. Using an exhaust fan that vents chemicals directly outdoors.
While opening a window helps, an exhaust fan specifically designed to vent chemical fumes directly outdoors is the most effective measure for removing chemical vapors from the breathing zone and preventing their buildup in the salon. Recirculating air would be detrimental.
Why the other options are wrong
- A. A surgical mask protects against droplets, not chemical vapors or fumes.
- C. Opening a window provides some ventilation but may not be sufficient for strong chemical fumes.
- D. Recirculating air would trap and spread chemical fumes throughout the salon, making it worse.
