LOTO Equipment Locks Tags and Hasps
Lock out tag out equipment including padlocks, danger tags, and multi-lock hasps are the physical devices that prevent accidental re-energisation during maintenance and construction work. Using the correct LOTO equipment and applying it properly is essential to keeping workers safe from unexpected energy release. This talk covers the types of LOTO equipment, how they are used, and the rules that apply.
Key Hazards
Accidental re-energisation when isolation is not physically locked
Wrong lock removed allowing equipment to restart while workers are present
Tags used alone without locks providing inadequate physical prevention
Equipment started with multiple trades still working under isolation
Control Measures
- Apply a personal padlock to every isolation point before starting any maintenance or installation work.
- Use a unique, individually keyed padlock that only you hold the key for.
- Attach a completed danger tag to each lock clearly stating your name, date, and reason for isolation.
- Use a multi-lock hasp when more than one person needs to work under the same isolation.
- Ensure every person working on the isolated system applies their own lock to the hasp.
- Never use another person's lock or remove anyone else's lock from an isolation point.
- Remove your personal lock only when you have confirmed all your work is complete and safe.
- Store LOTO equipment in a dedicated, accessible location on site with sufficient supplies.
- Brief all operatives on the LOTO procedure and the correct use of locks, tags, and hasps.
Remember
- Apply your own personal padlock to every isolation point before starting work
- Never remove another person's lock from an isolation point under any circumstances
- Use a multi-lock hasp when multiple people need to work under the same isolation
- Attach a completed danger tag stating your name, date, and reason for the isolation
- Remove your lock only when you have confirmed all your work is complete and safe
