What does "Lockout/Tagout" (LOTO) refer to in a safety context?

"Lockout/Tagout" (LOTO) refers to procedures that are specifically designed to ensure that dangerous machines are completely shut off and cannot be started up again until maintenance or servicing tasks have been finished. In a workplace where machinery is involved, such as manufacturing facilities or workshops, LOTO procedures are crucial for protecting workers from accidental machine start-up that could lead to severe injuries or fatalities.

The process involves using locks to secure the energy-isolating devices (such as circuit breakers or valves) and applying tags that indicate that maintenance work is being performed. This practice is essential for compliance with safety regulations and standards, as it creates a safe working environment by preventing the unintended energization of equipment while maintenance is occurring. Proper training and adherence to LOTO procedures help ensure that workers are protected during servicing operations, making it a central aspect of occupational safety protocols.

Other options do not encompass the critical safety and preventative maintenance aspect that LOTO is designed to address, which focuses specifically on the safe deactivation of machinery during servicing.
