A landscaping crew is using an angle grinder to cut metal edging. The grinder's wheel guard has been removed by a previous user to facilitate a specific cut. What is the immediate and most appropriate action the current operator should take?
- AProceed with the cut, being extra careful and wearing additional gloves.
- BUse a different cutting tool to complete the task.
- CReport the missing guard to the supervisor after the task is finished.
- DReplace the wheel guard before using the grinder.
Show answer & explanationAnswer & explanation
Correct answer: D. Replace the wheel guard before using the grinder.
Operating an angle grinder without its wheel guard is extremely dangerous and a serious Cal/OSHA violation. The guard is a critical safety device designed to protect against flying debris and wheel breakage. The immediate action must be to replace it before any operation.
Why the other options are wrong
- A. Operating without a guard, even with extra care, is highly unsafe due to the risk of severe injury from projectiles or wheel disintegration.
- B. While using a different tool might be an option if the guard cannot be replaced, the primary and immediate action for the grinder itself is to restore its safety device.
- C. Reporting after the task is finished means operating the equipment unsafely, which is unacceptable. The hazard must be addressed before use.
