Which scenario requires the use of Lockout/Tagout procedures?

The scenario involving the removal or bypassing of a guard or safety device necessitates the use of Lockout/Tagout (LOTO) procedures because this action directly compromises the safety mechanisms that protect workers from potential hazards. LOTO procedures are designed to ensure that energy sources are properly controlled, and equipment is safe to service. When safeguards are removed or bypassed, there is a risk of unexpected machine start-up or release of hazardous energy, which can lead to serious injuries.

Using Lockout/Tagout procedures in this scenario would involve isolating the machine from its energy sources, ensuring that it cannot be accidentally activated while work is being performed. Tagging the equipment with a clear warning alerts all personnel that the machine is not to be operated until the lockout is removed, thereby enhancing safety.

In contrast, situations like making minor adjustments without changing the equipment state, routine cleaning of equipment, or checking equipment while it is operating do not typically require the rigorous application of LOTO. These activities can generally be performed without disabling the energy sources if they do not expose workers to risk.
