2. Outline • Overview • Hazards • Guidance/Regulatory Documents • Work Control Documents • Engineered Controls • Administrative Controls • PPE • Conclusions

3. Overview of JLab/NASA Engineered Nanoscale Material Work • Nano-material research at JLab since 2000 • Funded by NASA LaRC materials dir. • NASA PI is full time to Jlab FEL • Efforts for both Boron & Carbon • Synthesis by Laser ablation • Current efforts are in scale-up and determining material properties • Applications range from ‘light-weighting of materials’, synthetic muscles (highly piezoelectric), Hydrogen storage, Dirty Bomb clean-up suits (high strength + Boron for neutron shielding) to cell scaffold for re-growing of bone & nerve cells.

4. Hutch Configuration • Reduces laser hazard to class 1 • Can be used with Local Laser or FEL • Only Approved Laser Users allowed in lab during operations even though hazard is class 1

5. Hazards • Engineered Nano-materials • Vs. Non-engineered; cigarette smoke • Effects of Nanotubes May Lead to Cancer, Study SaysBy Rick WeissWashington Post Staff Writer, Wednesday, May 21, 2008;Microscopic, high-tech "nanotubes" that are being made for use in a wide variety… • Pressurized reaction chamber; covered earlier this morning • July 31, 2008 BOSTON—State safety officials have found that defective welding and corrosion led to a boiler explosion at the Salem Harbor Springs power plant that killed three workers. • Lasers; multiple class 4 lasers capable of many kilowatts and multiple wavelengths • We operate in either Exclusionary mode or inHutch Mode both reduce hazard to class 1 • Electrical, carcinogenic & flammable precursors, and machine tools

6. Guidance/Regulatory Documents • Nano-material work • NSRC Approach Document • NIOSH Approach Document • DOE, Inspector General’s Audit Report, Feb. 2008 “Nanoscale Materials Safety at the Department’s Laboratories” • DOE (draft, Aug 2008), “HSS Special Report on Nanoscale Material Work Practices” • Conform to the general principle in the National Research Council’s Prudent Practices for Handling Hazardous Chemicals in Laboratories: Laboratory personnel should treat “all new compounds, or those of unknown toxicity, as though they could be acutely toxic in the short run and chronically toxic in the long run.” • Hazard Communication and Chemical Hygiene Plans pursuant to OSHA regulations 29 CFR 1910.1200 and 1910.1450, respectively • Laser • ANSI Z136.1 Safe Use of Lasers • Design of LPSS based on this regulation + Jlab additions • General; ES&H CFR 851, DOE Worker Safety & Health Plan

7. Work Control Documents • Jlab ES&H Manual • FEL Chapter 3130 • Engineered Nanomaterial Hazard Awareness Training for Incidental Personnel at the Jlab FEL • Training given to those that frequent FEL • ESAF (Experimental Safety Assessment Form) • Worker specific training • LSOP (Laser Safe Operating Procedure) • Lab specific training • SOP (Standard Operating Procedure) • Job specific training • Example is target preparation SOP • If it’s regularly done; then write the SOP, if NOT – Do I need a TOSP?

8. Engineered Controls • Work Area Design • Contamination control, step-off pads, buffer area • HEPA vented hoods • Integrated Laser Personnel Safety System (LPSS) • Design criteria from ANSI standards + added JLab requirements • Smart Card access • Hutch Mode operations • Laser crash buttons • Interlocked smoke detectors

9. Access Control • Crash Button • ODH Alarm • Laser Warning light • Room view video • Nanomaterial Hazard sign • Laser Hazard Identification • Smart card Access • Entry Status lamps • ESAF & SOPs on door

10. Administrative Controls • Laser safety training • Chemical Hygiene Plan; As required in 10 CFR 851.23, develop and implement a chemical hygiene plan satisfying the criteria in 29 CFR 1910.1450 (Jlab ES&H 6610) • Good housekeeping consistent with the operational safety procedure • HEPA vacuum used for nanomaterial clean-up • Proper labeling for presence of possible engineered nanomaterials • Hazardous waste program • Satellite accumulation area set up • Established procedures for transportation • Medical surveillance of workers

11. Personal Protection Equipment • When handling or transferring material; • Lab coat • Nitrile double gloves • Respirator • Safety glasses • When operating laser safety glasses are worn • Goes beyond ANSI standards

12. Conclusions • High ‘marks’ from recent HSS review, Notable practices; • The FEL laboratory ventilation was specifically modified for nanotube work to minimize exposure to any type of airborne contamination… • The nanomaterial procedure conservatively requires the local exhaust systems to be cleaned annually using asbestos-like cleaning techniques, including a requirement to change out the HEPA filters annually. • TJNAF has established conservative PPE requirements in excess of the NSRC Approach document for nanomaterial handling… • TJNAF has developed an MSDS specifically for boron nitride nanotubes produced as a result of the current R&D. The MSDS is comprehensive, easy to understand, and addresses all MSDS subject areas required by OSHA standard 29 CFR 1910.1200(g). • Although nanomaterials are not specifically addressed in Federal waste disposal … waste streams containing nanomaterials… are conservatively marked, classified, and dispositioned. • TJNAF has established specific procedures for transportation of nanoscale materials, both on site and off site
