The warning symbol that includes a wrench is used to indicate what?

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

Answer: (C)

A wrench in a warning symbol signals a maintenance-related message. It’s an indicator that something in the equipment needs service, inspection, or routine upkeep rather than presenting a specific danger or a required tool for immediate operation. That makes it a general notice about the equipment’s condition, prompting maintenance action.

So the best match is a general issue: it’s not pointing to an electrical hazard (that would be a different symbol), and it isn’t specifying that a particular tool is needed to operate. Nor is it a strict “maintenance required” tag in all contexts—the wrench icon here functions as a general maintenance/service alert, hence the choice of general issue.
