⚠ Lockout/tagout is life-safety. Follow your employer's written LOTO program and any authority-having-jurisdiction requirements (OSHA 1910.147 in the US, CSA Z460 in Canada, plus provincial OHS regs). This checklist is a memory aid — it does not replace training, hazard assessment, or a personal lock/tag. Every worker must apply their own lock; never rely on someone else's. If in doubt, escalate.
