Take a Look at the Facts

Employee is sweeping ground wheat from around machinery

Work rules did not address cleaning around operating machinery


Take a Look at the Facts (cont.)

4-inch gap between guard and the machine body

She reaches under a belt and pulley guard with a hand brush

No guard under the belt and pulley assembly


Take a Look at the Facts (cont.)

Left glove is caught by in-running belt, and hand is pulled into motor pulley

Employee loses middle and index fingers and suffers two compound fractures to left arm


What Do You Think Went Wrong?

Why did the employee reach under the guard?Was the employee aware of the hazards?Did the employee see the guard and assume

there was no hazard?Did the employee’s glove play a role?Should workers clean under operating machinery? Who should inspect machine guarding?


Let’s Review the Causes

Employee reached under guardEmployee did not inspect guardGuard did not completely cover the hazardEmployee attempted to clean under

operating machineryLack of work rules and training


Let’s Talk About Guard Types

Fixed guards

Interlocked guards

Adjustable guardsSelf-adjusting

guards


Keys to Adequate Guarding

Prevent bodily contactSecure guards to machineryProtect from falling objectsCreate no additional hazardsEnsure safe lubricationDoes not interfere with production efforts


Don’t Let It Happen to You

Avoid machinery unless properly trainedLearn to identify the point of operation and

mechanical motion Make sure all machine guards are in placeUnderstand guarding requirementsKnow who to contact if a guard is missing,

damaged, or inadequate
