SBN

• Prior to operation, experiments, projects, and R&D (Research and Development) efforts may require an ES&H (Environment, Safety, and Health) review depending on the hazards or risks involved. The ES&H review may consist of multiple reviews by subject matter experts (SME’s) from a variety of committees depending upon the hazards involved. The ES&H review procedure is designed to review these projects and to ensure proper documentation and reviews have been conducted. The Operational Readiness Clearance (ORC) process is used to capture the recommendations, findings, and ultimate recommendation to operate from these various committees.

What is an Operational Readiness Clearance Review?

1/27/16 Linda Bagby | ICARUS Electronics Meeting3

SBN

• All experiments within the Short Baseline Neutrino (SBN) program in Neutrino Division (ND) follow the Particle Physics Division (PPD) guidelines for Operational Readiness Clearance (ORC) reviews.

• Link to the Particle Physics Division Operational Readiness Clearance (PPD ORC)

• Link to the Fermilab Environment, Safety and Health Manual (FESHM)

Guidance Sources

SBN

• Use the PPD ORC page to determine the hazards for a given subsystem• http://www-ppd.fnal.gov/ESHBMGOffice/orc.html• Hazards include:

– Flammable (Gases or Liquids)– Gases– Chemicals– Radioactive Sources– Target Materials– Nuclear Materials– Class 3b or Class 4 Lasers– Electrical Equipment– Mechanical Structures– Vacuum Vessels– Pressure Vessels and Pressure Piping– Fire and Life Safety– Radiation Safety– Trip, Fall, and Strain relief considerations

Where does one start??

SBN

On the Particle Physics Division Operational Readiness Clearance page, under Electrical Equipment, there are 2 main links to use as guidance. • Electrical Equipment

– Electrical Safety ORC Review Tips– Electrical Design Standards for Electronics to be used in Experiments at Fermi

lab– Necessary Documentation:

• Simplified (block) electrical diagram of entire installation, including commercial components, with special emphasis on power handling issues. These must be of sufficient detail that reviewers can verify the experimenters have observed good systems engineering practices and have used proper fusing, wire sizes, insulation, termination, etc.

• Line diagrams of custom manufactured circuitry or modifications of commercial components of similar detail.

The Environment, Safety, and Health (ES&H) webpage has links to all Fermilab Environment, Safety, and Health Manual (FESHM) documents.• FESHM 9000 Electrical Safety chapters.

Electrical Equipment Highlight

SBN

There are 2 ways to go about obtaining an Operational Readiness Clearance, the difficult way and the easy way.

• Difficult: Submit a review request after all equipment is installed.– Problems: For large experiments this plan is plagued with

delays due to the time required to review equipment a committee member is seeing for the first time, turn around time of possible rework, availability of the reviewer.

• Easy: Follow a 3 step process throughout the duration of the project.– Problems: I haven’t found any yet.

Modes of Attack

1/27/16 Linda Bagby | ICARUS Electronics Meeting7

SBN

• Safety Engineering Design Review (SEDR)• Performed on custom designed or modified commercial

equipment.• Requirements (chassis level)

– Simplified (block) electrical diagram of entire installation, including commercial components, with special emphasis on power handling issues. These must be of sufficient detail that reviewers can verify the experimenters have observed good systems engineering practices and have used proper fusing, wire sizes, insulation, termination, etc.

– Line diagrams of custom manufactured circuitry or modifications of commercial components of similar detail.

– Sample of equipment to be reviewed.• Should be done during the PRE-PRODUCTION phase of a

design to allow time to complete any ‘required’ findings.

3 Step Process: Step 1

1/27/16 Linda Bagby | ICARUS Electronics Meeting8

SBN

• partial Operational Readiness Clearance (pORC)• A mechanism for powering up one subsystem while others are being

installed or assembled.• Performed on a subsystem’s fully populated electronics racks or a

subsystem’s collection of equipment.• Includes all intra AND inter rack connections, including external AC

Distribution.• Requirements (rack or subsystem level)

– Simplified (block) electrical diagram of entire installation, including commercial components, with special emphasis on power handling issues. These must be of sufficient detail that reviewers can verify the experimenters have observed good systems engineering practices and have used proper fusing, wire sizes, insulation, termination, etc.

– Line diagrams of custom manufactured circuitry or modifications of commercial components of similar detail.

– Fully populated rack.• Can be done at experiment’s enclosure or other site before racks are moved

to enclosure.

3 Step Process: Step 2

1/27/16 Linda Bagby | ICARUS Electronics Meeting9

SBN

• Final Operational Readiness Clearance Walkthrough (ORC)• Documentation consists of a ‘wrapper’ around all of the

subsystem partial Operational Readiness Clearance review findings and responses.

• This is a final walkthrough by safety to insure the installation is complete and ready to go.

3 Step Process: Step 3

1/27/16 Linda Bagby | ICARUS Electronics Meeting10

SBN

• Per the Department of Energy’s prime directive to Fermilab, Fermilab is required to follow the National Electrical Codes (NEC) and Occupational Health and Safety Administration (OSHA) guidelines.

• OSHA requires all commercial equipment to be reviewed by a Nationally Recognized Testing Laboratory (NRTL).

• A current list is herehttps://www.osha.gov/dts/otpca/nrtl/nrtllist.html

Custom Designed Determination

1/27/16 Linda Bagby | ICARUS Electronics Meeting11

SBN

• OSHA does not recognize CE has a Nationally Recognized Testing Laboratory.

• https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=FAQ&p_id=178

• However, there are 3 solutions:– Safety Engineering Design Review (SEDR).– Have vendor obtain a Nationally Recognized Testing Laboratory (NRTL)

stamp.– Have a Nationally Recognized Testing Laboratory (NRTL) representative

perform certification of equipment on site.

CE Rating

1/27/16 Linda Bagby | ICARUS Electronics Meeting12

SBN

• Defined Operational Readiness Clearance.• Provided links to guidance for review preparation.• Described a 3 step process to minimize the time it takes to

complete the review.• Highlighted requirements for Electrical Equipment.• Described Nationally Recognized Testing Agency stamps for

commercial equipment.• I am here to help and shepherd everyone’s effort in

completing the reviews in a timely manner.
