TITLE:	ES&H Manual
DOCUMENT ID:	6650 Appendix T1 Minimum Mitigation Requirements for Engineered Nanoparticles

1.0 Purpose

This appendix defines Jefferson Lab’s minimum mitigations requirements for engineered nanoparticles (NP). These minimum requirements are consistent with the requirements of 10 CFR 851 and Department of Energy (DOE) Notice N456.1.

2.0 Scope

This appendix addresses minimum hazard mitigations when working with engineered NPs.

3.0 Responsibilities

3.1 Environmental, Safety, Health, and Quality (ESH&Q) Industrial Hygiene (IH)

· Annually surveys and certifies exhaust ventilation and vacuum cleaners used in designated NP areas.

· Approves personal protective equipment (PPE) for NP handling.

· Coordinates NP waste disposal.

· Posts signage on all areas designated as NP work areas.

3.2 Engineered NP worker

· Contacts ESH&Q IH for appropriate area and container labeling and signage requirements.

· Contacts ESH&Q IH prior to removing any NP, including waste, from a designated area.

4.0 Process Steps

Below are minimum requirements that must be incorporated into NP activities.

4.1 Ventilation:

Work that could generate airborne unbound engineered NP is conducted in ventilated enclosures (such as a ventilation hood, glove box, or glove bag) designed to protect workers from airborne contaminants. Ventilation systems for these enclosures are protected with high efficiency particulate air filtering system (HEPA) (or Ultra Low Purifying Air, ULPA) filtration systems to “scrub” air prior to being exhausted outdoors.

4.1.1 If the activity cannot be enclosed alternative controls such as local exhaust ventilation systems may be used to capture fugitive NP at the source.

4.1.2 Ventilation systems that can produce “blow back” such as a laminar flow hood are not used with NP.

4.1.3 Enclosed systems under positive pressure are used in a negative pressure enclosure and exhausted prior to opening.

4.1.4 Controls are in place to exclude NP from any exhausted air entering the work space; exhausted air is not re-circulated within the laboratory, even if HEPA-filtered.

4.1.5 Exhaust ventilation systems are annually surveyed (e.g., face velocity/capture velocity) to control worker exposure, and

4.1.6 HEPA filters in exhaust systems and vacuum cleaners in NP work areas are annually certified to verify filter efficiency.

4.2 Storage

ESH&Q IH is contacted prior to storage of any NP for guidance as to the proper storage requirements based on material composition. Minimum requirements include:

4.2.1 NPs are only stored in designated areas.

4.2.2 Containers are closed at all times while in storage.

4.2.3 Labels affixed to all containers (see Section 4.3 Posting and Labeling Requirements)

4.3 Posting and Labeling Requirements

4.3.1 Designated engineered NP areas (e.g., laboratory door, glove box) are posted:

4.3.2 All engineered NP storage containers are labeled:

4.4 Personal Protective Equipment (PPE):

PPE is selected per specific NP. PPE requirements are documented in applicable OSP or THA for a specific NP activity.

4.5 Waste Management:

· NPs are managed as a hazardous waste in accordance with ES&H Manual Chapter 6761 Hazardous Waste Management. NPs are NOT released to the sanitary sewer or disposed of in regular trash bins.

o All waste (including wipes, filters, gloves, etc.) that has been in direct contacted with NPs is wetted, bagged, and placed in a designated Satellite Accumulation Area (SAA) or ESH&Q IH is contacted for immediate removal.

4.6 Housekeeping:

· Surfaces where NPs are used are cleaned at the end of each work-shift using approved HEPA vacuum and wet-wiping.

o A HEPA vacuum (approved by Industrial Hygiene) is required in work areas where NPs are used.

o Used wipes are disposed of in designated SAA.

4.7 Transportation Requirements:

Prior to off-site transport, NP are evaluated by ESH&Q IH as to whether it is a Department of Transportation (DOT) hazardous material. Guidance is provided regarding packaging and carrier qualification requirements.

4.7.1 Documentation and notifications for off-site transfer of NP includes:

· Available descriptions of the material (e.g., Material Safety Data Sheets (MSDSs)). Researchers prepare a document that describes properties that are reasonably likely to be exhibited by samples.

· A notification to receiving facility of the incoming shipment.

4.7.2 The following requirements must be met if transported by personal vehicle:

· Driver must have a valid driver’s license,

· Vehicle is in good mechanical condition with valid state inspection sticker,

· Vehicle has minimum liability insurance required by the state, and

· Driver obeys all traffic rules.
