Administrative Control Using Locks and Tags for administrative
control applications.
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.
Jefferson Lab’s construction subcontractors follow OSHA 29 CFR1926 Safety and Health Regulations for Construction; which is the standard for construction work activities. Subcontracting Officer’s Technical Representatives (SOTRs) are tasked with reviewing subcontractors programs for compliance.
