NSLS Experiment ESH ReviewThe Process

• Managed by ESH&Q with Operations support• Experiment Review Coordinators (ERC)

• 2 people; 1 back up• Electronic submission (1 week advance – routine)• Lead Experimenter assigned• ESH review: ESH staff, Local Contact & User discussion

• Approved; Approved requires notification; ERC review required• User arrives

• Contact Operations Coordinator (Op Co)• Op Co prints approved form; enables the beam line (Authorization to start)

o Contact Experiment Review Coordinator (if requested)o Review and post formo Beam line safety checklist (configuration control)o Check User trainingo Confirm Lead Experimenter

• Experiment begins

7 BROOKHAVEN SCIENCE ASSOCIATES

• Materials (qty; return; store; barcode)• Equipment• Tasks; Risks; Contingency plan• Waste• Specific questions

• Human materials / animals (ethics)• Virus, toxin, select agent, viable• Radioactives• Laser• Wet chem• Haz waste• Magnets (stray field)• Non-NRTL electrical• Nano• Reactive (peroxide, explosive, pyrophoric …)• Cryogens

User Training

• Efficient; user specific• 3 parts; ~1.5 hrs

• BNL General Employee Radiological Training (web)• NSLS User Safety (web)• Beam Line Operational Safety Awareness (BLOSA) (hands on at beam line; local

contact)• NSLS User Safety (8 sections)

• Introduction (objectives ESH policy; directions)• Radiation (posting, dosimetry, shielding, interlocks, materials)• Electrical (posting, breakers, LOTO, tags, cables)• Chemicals & wastes (labeling, storage, disposal)• Other (Be, cryo, laser; magnets, compressed gas)• Facility and beamline (SAF’s, BLOSA, vacuum, unattended ops, stop

work)• Emergencies (fire, evacuation, reporting)• Policy (ID badges, traffic, security, Lyme, housekeeping,
