Work Planning & Control - Documents & Forms
Certain hazardous, recurring activities performed at Jefferson Lab are restricted and only undertaken when authorized by a Work Control Document. These documents ensure that all hazards have been considered and associated risks are acknowledged and mitigated by those performing the tasks..
(see https://www.jlab.org/ehs/workcontrol.html for old listing)
A formal work control document is developed at Jefferson Lab when work activities fall into one of the following categories: Cannot be conducted in a manner consistent with ES&H Manual requirements as written; Introduces a new/anticipated/previously unrecognized hazard issue; Determined to have an unmitigated Risk Code (RC) of 3 or 4. (For instructions see: ES&H Manual Chapter 3310 Appendix T1 Operational Safety Procedure (OSP) and Temporary OSP Procedure or 6410 Laser Safety Program.)
An OSP is developed when work activities: Cannot be conducted in a manner consistent with ES&H Manual requirements; Introduce a new/previously unrecognized hazard issue; Have an unmitigated Risk Code (RC) of 3 or 4, as determined by a Task Hazard Analysis (THA); or When Standard Protecting Measures are unable to reduce the hazard to RC <3.
LOSPs addresses minimum safety requirements to mitigate the hazard issues associated with Class 3B and Class 4 lasers. This does not preclude the need to incorporate additional activities to ensure the safety of people, equipment, and the environment for activities associated with laser work
Entering a confined space for any reason is considered to be an unmitigated Risk Code >2 and requires a Work Control Document i.e. Confined Space Entry Permit or Alternate Entry Certificate as appropriate.) Only when all hazard issues associated with the area and the work activity are mitigated can access to the area be authorized.
The ODH Safety Review Form is to be completed for any area before an ODH is introduced, or when it is recognized. This includes, but is not limited to, fixed sources and permanently installed equipment. The ODH Safety Review Form is also used to assist in identifying areas that have the potential to become oxygen deficient. If the potential ODH is located outside, this ODH Safety Review procedure is not appropriate. For these cases, the individual is directed to review ES&H Manual Chapter 6540 T4 Oxygen Deficiency Hazard (ODH) Risk Assessment for guidance.
Any work activity that requires an open flame (reater than a BIC lighter); welding or brazing activities; and /or spark producing grinding/cutting operations, requires a Hot Work Permit unless it is performed in a designated area authorized by an Operational Safety Procedure (OSP).
A Digging and Excavating Permit is required for any mechanized or hand tool excavation that penetrates the ground greater than 12-inches. Excavation, digging, or boring into soil is performed only after utilities have been located and marked by a competent person.
Blindly penetrating (cutting, drilling, or otherwise) into walls, floors, or ceilings is performed only after utilities have been located and marked by a competent person. A permit does not guarantee that a utility is not present. All precautions need to be taken to safe guard individuals during the penetration activity.
Work performed on AC electrical equipment exposes workers to potential electrical hazards that may result in serious injury or death. Work on energized equipment is not allowed except when de-energizing the equipment either introduces additional or increased hazards; or it is infeasible to perform the work de-energized. An Energized Electrical Work Permit (EEWP) is required prior to performing this type of work. (For instructions see ES&H Manual Chapter 6220 T1 Energized Electrical Work Permit.)
Work on energized equipment is only allowed when de-energizing the equipment either introduces additional or increased hazards; or is infeasible to perform the work. Work on energized electrical eqipment for the purposes of diagnostics is permitted without an EEWP, provided appropriate safe work practices and PPE are used in accordance with NFPA 70E Articles 110 and 130.
