Valve lockout tagout (LOTO) is a vital safety procedure in industrial settings, particularly where heavy machinery, hazardous energy sources, or complex systems are involved. It ensures that equipment is properly secured and cannot be accidentally activated during maintenance or repair activities, protecting workers from potential injury or death. This article will explore the significance of valve lockout tagout, its implementation, and the critical role it plays in maintaining a safe work environment.

What is Valve Lockout Tagout? Valve lockout tagout is a safety protocol designed to prevent the unintended release of hazardous energy while maintenance or servicing activities are underway. It involves two primary components： Lockout： The process of physically isolating a valve or piece of equipment by using a lock to prevent any accidental operation. This usually involves placing a lock on a valve handle, switch, or power supply that ensures the equipment cannot be turned on until the lock is removed. Tagout： This is the process of placing a clearly visible warning tag on the locked equipment to alert other personnel that the machine is under maintenance and must not be operated. The tag typically includes important information, such as the name of the person performing the work and the expected duration of the maintenance.
