What does Signal 4 mean?

• A. On location
• B. Fire hazard
• C. Work stoppage
• D. Clear and understood

Answer: (D)

Signals on the job site are standardized so everyone can communicate quickly and clearly in a noisy, hazardous environment. Signal 4 is used to confirm that a directive has been received and understood, and that there are no questions or missing details. In practice, when someone gives a safety instruction or a step to perform, using this signal shows that you understand what’s being asked and you’re ready to proceed. This kind of acknowledgment helps prevent mistakes and keeps work moving safely. Other signals indicate different statuses—such as being on location, flagging a fire hazard, or stopping work—but they aren’t about confirming understanding.
