What enclosure may contain a flammable or combustible vapor as a result of spraying operations?

• A. Spray booth
• B. Safety cabinet
• C. Dust collector
• D. Vent hood

Answer: (A)

Vapors produced during spraying can ignite if they accumulate in the surrounding air. An enclosure around the spraying operation provides controlled containment and ventilation to remove those vapors from the work area, keeping their concentration below flammable levels. A spray booth is specifically designed for this purpose, enclosing the process and providing exhaust and often explosion‑proof construction to capture and remove vapors safely. In contrast, a safety cabinet is for storing materials, a dust collector handles solid particulates, and a vent hood only captures fumes at the source without fully enclosing the process, so it doesn’t contain the vapors the way a spray booth does.
