What will be used where small parts are customarily cleaned with flammable liquids?

• A. Bench cans
• B. Open pans
• C. Glass beakers
• D. Plastic bags

Answer: (A)

When cleaning small parts with flammable liquids, you need a container that safely traps vapors and prevents ignition while you work. Bench cans are metal containers with a tight-fitting cap and a flame-arresting vent, designed specifically for small parts and flammable solvents. They minimize vapor release to the bench, reduce splash, and provide a safe, readily accessible place to rinse or soak parts right at the work area. Open pans allow vapors to escape and raise fire risk; glass beakers are fragile and lack proper vapor control and flame arresting features; plastic bags can dissolve or permeate with solvents and don’t provide reliable containment. So bench cans offer the appropriate containment, safety, and practicality for this task.
