What is the warning symbol that includes a wrench?

• A. Maintenance required
• B. Tool required
• C. General issue
• D. Electrical hazard

Answer: (C)

When you see a warning symbol that includes a wrench, the visual cue is signaling a maintenance or servicing concern. The wrench points to tools and repair work, so this icon communicates that there is a general issue with the equipment that should be checked and possibly serviced before use. It isn’t pointing to a specific hazard like electricity or a required tool action; it’s flagging a broader maintenance status. A tool-required symbol would specifically indicate you must have a tool to proceed, and an electrical-hazard symbol communicates shock risk with a different image. So the wrench-with-warning fits best as indicating a general issue requiring attention and possible maintenance.
