2017 LOTO Program Revision
Pub-3000, Chapter 18 revision is now in full effect, as of March 31, 2017!
This is a minor revision to the LOTO Program. The intent is to match efforts in the Electrical Safety Program (ESP) revision to streamline requirements for Qualified Electrical Workers (QEWs) and electrical work, and it also includes a few editorial corrections. This revision is intended to help facilitate implementation for our researcher community.
|The revised PUB-3000 Chap 18, Lockout\Tagout Program describes our institutional requirements and processes to ensure proper control of hazardous energy.||To review just the primary changes to the document, view the Analysis of Changes powerpoint below:|
What is Lockout/Tagout (LOTO)?
- LOTO is a formal process for controlling hazardous energy.
- LOTO protects personnel working on equipment from the unexpected release of hazardous energy.
- Lockout/Tagout (LOTO) is composed of two principal process components:
- Deenergization removes all energy sources from the system.
- Control prevents re-energization.
For more information on the general principles of LOTO, please read Appendix C in the ES&H LOTO Program.
When is LOTO required?
LOTO is generally required for all servicing and maintenance of equipment that has the potential to cause injury. This also includes construction and demolition.
More specifically, certain programs define hazardous energy thresholds that trigger the application of LOTO. For example, electrical line voltage above 50 VAC is considered hazardous and requires LOTO whenever a person is closer than 42 inches of exposed electrical circuit parts (750V and less).
Who is required to LOTO?
Each and every person who is performing work on the equipment or who is entering an area with hazards controlled by LOTO, is required to apply their personal LOTO lock and tag. This requirement for personal LOTO is essential.
Berkeley Lab employees who participate in LOTO must have completed the following training course: EHS0370 – Lockout/Tagout for Authorized Persons. Click the Sign up for Training link on the left sidebar to register for training.
Subcontractors who participate in LOTO must complete EHS0379 – Lockout/Tagout Orientation for Subcontractors, have a designated LOTO Responsible Individual, and have an approved Subcontractor LOTO Permit. For non-construction subcontractors and vendors, this is initiated and coordinated through the Berkeley Lab sJHA process. For construction subcontractors, contact the assigned Facilities Construction Manager or Project Manager.
