NIC Nail Technician Written ExamSafety and RegulationsHard
A salon technician is performing a service using an acrylic liquid that emits strong fumes. The salon has a general ventilation system, but the technician still notices a lingering odor and occasional headaches. What specific type of ventilation system is recommended by OSHA and health organizations for controlling chemical vapor exposure in nail salons?
- APortable HEPA filter air purifiers placed throughout the salon.
- BCeiling fans to circulate air more effectively.
- CLocal Exhaust Ventilation (LEV) system with capture at the source.
- DWhole-building HVAC system with increased air changes.
Show answer & explanationAnswer & explanation
Correct answer: C. Local Exhaust Ventilation (LEV) system with capture at the source.
OSHA and health organizations specifically recommend Local Exhaust Ventilation (LEV) systems for nail salons. LEV systems capture chemical vapors and dust at their source (e.g., at the nail station) before they can spread into the general salon air, providing the most effective control for airborne contaminants.
Why the other options are wrong
- A. HEPA filters are excellent for particulate matter but are not typically designed to effectively remove chemical vapors and gases, which are the primary concern with acrylic liquid.
- B. Ceiling fans merely circulate contaminated air without removing it, potentially spreading fumes rather than controlling them.
- D. While increasing air changes is part of general ventilation, it's less effective than source capture for strong chemical fumes, as it dilutes rather than removes at the source.
Local Exhaust Ventilation (LEV)
An engineering control system that captures airborne contaminants, such as chemical vapors, at or near their source and exhausts them safely away from the breathing zone.
- Most effective for chemical vapor control in salons.
- Captures contaminants at the source.
- Recommended by OSHA for nail salons.
Memory trick: Local Exhaust: Capture fumes at the station, for healthy respiration!
