Lockout/tagout (LOTO) padlocks are vital components in industrial safety systems, designed to protect workers from the hazards associated with the unintended activation of machinery and equipment during maintenance. In workplaces such as factories, power plants, and construction sites, employees work with dangerous machines that could cause serious injuries or fatalities if not properly controlled during service or maintenance. The role of lockout/tagout padlocks is to ensure that energy sources to equipment are securely isolated, rendering machines inoperable until the work is completed. This article will delve into the importance, functionality, and advantages of LOTO padlocks in maintaining workplace safety.
