Which device is used to provide a clean environment for painting?

• A. Dust hood
• B. Spray booth
• C. Ventilation hood
• D. Paint booth

Answer: (B)

A spray booth is built to create a clean, controlled space for applying paint. It brings in filtered air and exhausts it through designed filtration, trapping dust and overspray while removing solvent vapors. This keeps dust from settling on the wet finish and reduces environmental and safety risks from fumes, helping the paint dry smoothly and look right. The other devices serve different tasks—dust hoods capture dust near sanding or grinding, ventilation hoods vent fumes at a workstation without enclosing the painting area, and a paint booth is a broader term, whereas the spray booth specifically provides the dedicated, filtered environment needed for painting.
