what makes gate guards effective?

Analyze the function of gate guards

Gate guards act as movable barriers that interlock with the machine's power source.

Evaluate the options

• Option 1: Locking from the inside is not a standard safety mechanism for machine gate guards.
• Option 2: Requiring two employees due to weight is inefficient and not a safety design principle.
• Option 3: Keeping management out is not the purpose of safety safeguarding.
• Option 4: Interlocking ensures the machine cannot cycle or run while the gate is open, preventing access to hazards.
