Steel plants form a crucial backbone of the national economy and directly influence people’s livelihood, but the continuous upgrading of metallurgical technology has also increased the complexity and risk of high-temperature smelting, continuous casting, rolling, and heavy material handling. Multiple hazardous energy sources—electrical, mechanical, thermal, hydraulic, and pneumatic—are concentrated in dense production areas, so any negligence or omission in control can trigger serious accidents, equipment damage, or long-term production interruptions.

In this context, systematic Lockout Tagout (LOTO) energy isolation is no longer optional but a core safety requirement for steel plants, ensuring that all energy sources are identified, isolated, locked, and clearly tagged before maintenance, cleaning, or troubleshooting. A complete LOTO safety management procedure provides clear operational guidance to staff, standardizes how equipment is shut down and locked, prevents accidental restarts or misoperation, and helps create an intrinsically safe environment where workers can perform tasks with confidence and reduced risk.
