Which method must never be used to remove burrs, chips, metal cuttings from machines, work tables, stands, and floors?

• A. Hammer
• B. Wrench
• C. Brush
• D. Compressed Air

Answer: (D)

Removing burrs, chips, and metal cuttings from machines and work areas must be done safely by physically collecting the debris rather than blasting it away. A stream of compressed air can turn small chips into dangerous projectiles that can injure eyes, skin, or be driven into machinery, bearings, or electrical components. It also stirs up dust and can cause cold burns on exposed skin. Because of these hazards, compressed air is not used for cleaning these surfaces. Use a brush or broom and a vacuum (preferably a vacuum with a suitable filter) to remove chips and debris, and keep PPE like eye protection on. The other options are not intended for safe debris removal and can create or spread hazards.
