In industrial environments where heavy machinery, complex systems, or hazardous materials are involved, safety is of paramount importance. One of the most critical safety measures implemented in such settings is the Lockout-Tagout (LOTO) procedure. The LOTO system ensures that machinery or equipment remains de-energized and isolated during maintenance or repair, protecting workers from unexpected hazards. A key component of the LOTO procedure is the LOTO valve, which plays an essential role in controlling and isolating energy sources, particularly in systems that involve the flow of fluids, gases, or electricity.
What is a LOTO Valve? A LOTO valve is a specially designed valve that can be locked in a particular position to prevent accidental operation of equipment during maintenance or repair. The purpose of the valve is to isolate energy sources, such as pressurized liquids, gases, or electrical currents, to ensure that workers are not exposed to harmful conditions while performing their tasks. The valve can be locked in the “off” or “isolated” position, and often comes with a clear label or tag indicating that the equipment is undergoing maintenance and should not be operated.
