Lockout Tagout (LOTO) - Knowledge Center

Welcome to the Lockout/Tagout (LOTO) Knowledge Center. Why do you need to be concerned about LOTO? Employees can be seriously or fatally injured if machinery they service or maintain unexpectedly energizes, starts up, or releases stored energy. OSHA's standard on the Control of Hazardous Energy (Lockout/Tagout), found in Title 29 of the Code of Federal Regulations (CFR) Part 1910.147, spells out the steps employers must take to prevent accidents associated with hazardous energy. Practicing LOTO not only provides workers with protection from industrial machinery, but also protects your company from extensive OSHA fines that can be detrimental to company reputation and finances.
