What is a common hazard that Lockout/Tagout procedures address?

The correct answer is unexpected machine start-up, which is a primary focus of Lockout/Tagout (LOTO) procedures. LOTO is designed to prevent the accidental energization or startup of machinery and equipment during maintenance or servicing activities. This procedure ensures that all energy sources are effectively isolated and controlled, protecting workers from the potential hazards associated with sudden equipment operation.

By locking and tagging out machines, workers are alerted that the equipment is not in operation and that maintenance is being performed. This practice is critical because unexpected start-up could lead to severe injuries or fatalities, especially in scenarios where workers are in close contact with the equipment.

In contrast, while inadequate ventilation, insufficient lighting, and employee fatigue can pose safety hazards, they are not specifically addressed by LOTO procedures. LOTO primarily focuses on the control of hazardous energy to prevent the risks associated with machinery and equipment unexpectedly starting up during maintenance activities.
