|Chapter 6110 Hazardous Energy Control (HEC) Program|
The mission of Jefferson Laboratory as a scientific and engineering research center needs a large and diverse installed infrastructure, with facilities, equipment, and machines that have a wide variety of hazardous energy sources. The hazardous energy sources associated with scientific and research-related equipment may be completely different to those of facility infrastructure equipment. No matter what the source, mitigating hazards by isolating hazardous energy and using Lockout/Tagout (LOTO) is part of Integrated Safety Management at Jefferson Lab under Title 10 of the Code of Federal Regulations (CFR), Part 851, Worker Safety and Health Program, and several other CFR and regulatory safety standards.
This manual describes the Hazardous Energy Control (HEC) program and how to implement it. The goal of the HEC program is to prevent injury to staff or damage to government and proprietary property that may result from an unexpected startup of equipment and machinery, or inadvertent release of stored energy.
This program satisfies the requirements of OSHA 29 CFR1910.147 The Control of Hazardous Energy (Lockout/Tagout); the standard used when servicing and maintaining equipment/systems and NFPA 70E (2015 Edition), Article 120, Establishing an Electrically Safe Work Condition.
Jefferson Lab's construction subcontractors follow OSHA 29 CFR1926 Safety and Health Regulations for Construction; which is the standard for construction work activities. Technical Representatives(TRs) are tasked with reviewing subcontractors' programs for compliance.
LOTO is required whenever there is the potential for someone to be injured by the unexpected start-up of equipment or by a release of stored energy during maintenance and service work. ALL employees are responsible for the LOTO program and are to work safely to control the hazardous energy potentials when performing maintenance, repair, or modifications, or builds to any equipment.
The definition of hazardous energy is: Any form of energy that can cause personal injury or equipment damage. Forms and sources of energy can include:
This manual explains the Hazardous Energy Control (HEC) program and the minimum requirements to control hazardous energy for equipment with one or more sources of energy. This manual also addresses alternative means to isolate equipment and systems when the isolation is not required for maintenance or servicing (see section 4.2 and 10.13).

T1 Lockout/Tagout (LOTO) Procedure (Simple and Complex)
ES&H Manual Chapter 6110 Appendix T1 Lock, Tag, Try (LTT) Procedure contains the guidelines for locking and tagging out of hazardous energy sources when maintenance or service work is to be performed. LTT references in this appendix apply to maintenance, service, and construction applications. Refer to ES&H Manual Chapter 6111 Administrative Control Using Locks and Tags for administrative configuration control applications.
Configuration management requirements for equipment specific LTT procedures include:

T2 Special Lockout/Tagout (LOTO) Procedures
In accordance with Jefferson Lab procedures (ES&H Manual Chapter 6110 Appendix T1 Lock, Tag, Try (LTT) Procedure and ES&H Manual Chapter 6111 Administrative Control Using Locks and Tags) a lock and/or tag is removed only by the Qualified Tagger who placed it on the equipment, or an authorized person in the administrative control scenario. If the Qualified Tagger is unavailable, or the information is missing or illegible, ES&H Manual Chapter 6110 Appendix T2 Special Lockout/Tagout (LOTO) Procedures is utilized.
