Metal studs, saw blades, razor knives, and the like are sharp surfaces and could be contaminated with bloodborne pathogens.

• A. True
• B. False
• C. Not a concern
• D. Depends on material

Answer: (A)

Sharp surfaces can harbor bloodborne pathogens if they’ve come into contact with blood or body fluids. If you’re cut or punctured by a contaminated tool, those pathogens can enter your body, so you must treat any sharp object with potential exposure as potentially infectious and follow universal precautions. This means using gloves and appropriate PPE, handling blades and studs carefully, not recapping used blades, and disposing of sharps in approved puncture-resistant containers. Also, clean and disinfect tools and work areas after exposure and wash hands after handling. The risk isn’t eliminated by the material or shape of the item, so statements that say there’s no concern or that it depends on the material aren’t appropriate.
