- Because of the unique environment at Jefferson Lab, no two office environments are alike. If an area combines office space with other work, all hazard mitigation measures apply to all workers within the area. This chapter and its appendices provide mitigation requirements for the hazard issues associated with typical office work.
- The primary goals of the ergonomics program are to minimize employee exposure to risk factors for work-related musculoskeletal disorders, and to help improve work practices, furniture, tools, and equipment. Strategies for reducing such risk factors focus initially on engineering controls. When engineered controls are not feasible or sufficient, work practice controls and administrative controls, along with enhanced PPE are included.
- 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.
- Jefferson Lab uses administrative control locks and/or tags to restrict operation, use, or tampering of equipment or facilities for reasons other than personal protection. They are used to control equipment in a state desired by an authorized individual.
-
Interlocks serve to protect personnel and/or equipment by constraining the operation of equipment, either electronically or mechanically, and typically rely on a transducer, sensor, switch, or other physical mechanism to keep equipment from being placed in an unsafe state.
-
From time to time it may be necessary to bypass a system interlock. Jefferson Lab’s Interlock Bypass Policy describes the administrative requirements for bypassing system interlocks on equipment.
- This program describes required activities when using portable hand tools owned by and/or used on behalf of Jefferson Lab. See ES&H Manual 6121 Machine Tools for the safety requirements associated with machine tools. Jefferson Lab recognizes “machine” tools as pieces of equipment that:
- Is non-portable – secured for stability
- Has rotational motion, hydraulic, or leverage force
- Jefferson Lab requires that machine operators be adequately trained and familiar with the safety considerations involved in the operation of machine tools. Only personnel who have completed the required training can be authorized by the Machine Shop Manager to operate machine tools. This chapter provides the training and mitigation requirements to help ensure the safe operation of Jefferson Lab’s machine tools
- Hot work (e.g. welding, brazing, or spark producing grinding or cutting) is a common part of Jefferson Lab’s fabrication and construction activities. Because of the high temperatures involved and the potential for fire and serious personal injury, care is taken to ensure that work is performed safely. This hot work safety program has been developed to document Jefferson Lab’s minimum safety requirements for this type of work.
Described in this chapter are the fall protection systems (detailed in Appendices T1 and T2) used at Jefferson Lab. Fall protection options applicable only to low-slope roofs are detailed in Appendix T3. Instructions for completing a temporary permit for use of active fall protection systems are provided in Appendix T4i.
This program satisfies all applicable federal, state, and local requirements as outlined in Chapter 2410, Appendix T1: Hazard Issues List.
- Working at elevation on ladders and scaffolding is an identified hazard issue, recognized by JSA, that requires employee training, routine inspections, and maintenance. Ladder and scaffold safety requirements used to reduce risks are based on the laws, regulations, and references outlined in ES&H Manual Chapter 2410 Appendix T1: Hazard Issues List.
- This document, and its associated appendices, defines Jefferson Lab’s requirements related to gas cylinders, tanks, and dewars (cylinders) storage, movement, and labeling. Jefferson Lab bases the requirements for gas cylinders on applicable federal, state, and local requirements listed in ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List.
- The hazards associated with pressure and vacuum systems include leakage, rupture, explosion or implosion and can pose risks to personnel, property and the environment. The purpose of this program is to ensure that all personnel at Jefferson Lab involved in the construction, repair, alteration and operation of pressure and vacuum systems are cognizant of the hazards associated with these systems and construct, repair, alter and operate these systems in a safe manner. If at any time, questions arise as to the safety or proper procedures to be followed with pressure or vacuum systems, stop the activity and solicit help from a qualified source.
- At Jefferson Lab any area where work is assigned that is large enough to enter and perform work; has limited or restricted means of entry or egress; limited natural ventilation; and is not designed for continuous occupancy is considered to be a confined space. Working in confined spaces could potentially increase the risk of overexposure to atmospheric hazards and reduce a person’s ability to exit quickly due to physical hazards within the space. The purpose of this chapter is to provide awareness of the locations of known permit-required confined spaces (PRCS) at Jefferson Lab and establishes the minimum requirements necessary to prevent death or serious injury associated with entry into a PRCS.
