Machine Guarding Checklist

Guards fail, get removed for maintenance, or are bypassed as production pressure builds. Checking guards before and after operation catches problems while the machine is still safe to approach. It also confirms that the people running the machine know how to use the guards, how to respond when a guard is damaged or missing, and under what circumstances a guard may be removed. Reporting incidents and machine updates to a supervisor closes the loop, so the next shift does not inherit an unreported hazard.

Machine guarding covers fixed guards, interlocked guards, adjustable guards, and self-adjusting guards. The checklist covers each of the conditions a guard must meet: firm security, prevention of body-part contact, prevention of falling objects, support for safe and comfortable operation, and guarding of pulleys, belts, gears, chains, and fan blades. It also covers whether the machine can be lubricated without removing guards, whether it shuts off automatically when a guard is removed, whether guards keep operators from reaching running machinery, and whether the back and sides of the machine are protected. Warning signs and labels, lockout tags during guard removal, PPE, safe handling, emergency procedures, and supervision are checked alongside them.

Start the pre-operation review by recording who conducted the inspection, when, and where. Select the type of guards on the machine, then work through the condition and coverage questions, answering yes, no, or not applicable. Count the guards inspected, confirm they are labeled and signed, and assess operator training: how the guards work, the education and training behind that knowledge, what to do when a guard is damaged, incomplete, or inadequate, and how and under what circumstances a guard can be removed. Then check personnel practice: appropriate PPE, safe handling instructions, emergency procedures, and supervision. After operation, confirm guard condition again, verify that a lockout tag was placed when a guard was removed, and that all machine updates and incidents were reported to a supervisor. Close with the date, additional observations, an overall safety rating, and a signature.

A guard passes only if it is firmly secured, not easily removed, and prevents hands, arms, and other body parts from contacting dangerous moving parts, while also keeping objects from falling in. It must allow safe and comfortable operation, permit lubrication without removal, and, where applicable, the machine must shut off automatically when the guard is removed. Pulleys, belts, gears, chains, and fan blades must be properly guarded, and the back and sides of the machine must be protected. Warning signs and labels must be in place.

Operators should be able to explain how the guards work, show the education and training behind their knowledge, and describe the procedure when a guard is damaged, incomplete, or inadequate. They should know how and under what circumstances guards may be removed, wear appropriate PPE, follow safe handling instructions, and know emergency procedures for accidents involving machinery. Supervision should be adequate to ensure these procedures are followed.

A lockout tag should be placed whenever a machine guard is removed. During the post-operation review, confirm that all machine updates and all incidents were reported to a supervisor, then record the date of the review, any additional observations, an overall safety rating, and a signature.
