Guarding Guidelines: Which statement is a valid guarding guideline?

• A. Guards Should Be Fixed Directly Onto the Machine
• B. Guards May Be Removed During Operation if the Machine Is Paused
• C. Revolving Drums Can Be Left Unguarded if Running Slowly
• D. Fan Blades Above Seven Feet Do Not Need Guarding

Answer: (A)

Guards should be fixed directly onto the machine to provide a durable, reliable barrier that stays in place during operation. When a guard is attached to the machine or its frame as a permanent part of the equipment, it cannot be easily removed or displaced by workers, which consistently protects hands, clothing, and other body parts from moving parts. This stability is crucial because the danger from rotating or moving components exists whenever the machine is powered, not just when maintenance is being performed. Removing guards during operation or even while paused creates exposure to hazards, since the moving parts can come into contact with workers unexpectedly. Similarly, leaving rotating drums unguarded because they are running slowly still presents a real risk—the speed does not eliminate the hazard. Guarding is required regardless of how high a particular part is or how fast it appears to move, so assuming height or speed negates the need for guarding is incorrect.
