Operational Safety Procedures (OSP)

The Operational Safety Procedures (OSP) is a permit approved by the Physics Division for commissioning and operation of an experiment system and/or an entire detector. To facilitate experiment checkout, the experiment may desire that sub-systems be approved for commissioning prior to commissioning of the entire detector. In this situation, the EH&S Review Coordinator should request that a Temporary Operation Procedure (TOSP) be granted.

EQUIPMENT IDENTIFIED IN THE PRELIMINARY HAZARD ASSESSMENT SHALL NOT BE TURNED ON WITHOUT AN APPROVED TOSP OR OSP FROM THE PHYSICS DIVISION. A general guideline is that commercial equipment generally does not require a review prior to initial turn on. Experiment personnel should consult with the EH&S Review Coordinator if there is any uncertainty on the need for a review.

Eventually, as experiment checkout progresses and TOSPs and OSPs are granted for systems, all systems will be approved and operating. Prior to initial data taking, the Associate Director for Physics must certify the experiment readiness following the procedure documented in the Jefferson Lab EH&S Manual. The process includes the following components:

1.

Copies of signoffs from EH&S review committee(s). (This often is a collection of partial OSP's)

2.

Physics Division determination that the experiment is covered by existing/new SAD. (This means that the experiment complies with the requirements of a specific version of a Safety Assessment Document.)

3.

Physics Division determination of the need for an experiment Conduct of Operations (COO) document. (A COO may not be required if it is determined that sufficient engineered controls are in place to obviate the need for formal Conduct of Operations.)

4.

The Jefferson Lab Beam Containment Policy tasks the Radiation Control Group with specifying and maintaining configuration control on radiation shielding. Radiation Control Group reviews an experiments Radiation Safety Assesment Document (RSAD); their signature on the document indicates that radiation shielding is adequate and all configuration control items are in place. (Jefferson Lab is responsible for providing sufficient radiation shielding to protect experiment personnel as well as Jefferson Lab personnel and the general public. In some cases, specific components such as collimators or beam pipe must have their configuration maintained.

5.

Copy of the experiment hazard communications document (usually part of the COO).

6.

Verification statement from spokesperson that any required procedures are approved and in effect. (In the unlikely event that safety procedures are required, the experiment must demonstrate to the Associate Director for Physics that these procedures are in place and that appropriate training has been given.)

The Running Condition specifies the requirements for operation of beamline. Examples of requirements are beam energy and intensity limits, magnet current interlock limits, beam enclosure interlock status, etc.. The Running Condition is drafted by the experiment collaboration and approved by the Physics and Accelerator Divisions. An approved Running Condition is documented in the Accelerator Division's ``Beam Authorization Sheet," which is required by the Operations Group before beam may be transported to the experiment.
