Jefferson Lab has determined that working with hazardous materials carries an unmitigated Risk Code >2. At a minimum all tasks requiring hazardous materials are discussed with the supervisor prior to commencement of work. An Operational Safety Procedure (OSP) is written for any work considered to be Risk Code >2 in accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process.

Jefferson Lab allows limited quantities of hazardous material to be transferred¹ from one location to another (i.e.: on-site), and shipped² (i.e.: off-site) in accordance with identified safety standards. This appendix provides the process steps used to ensure appropriate safety precautions are utilized during these operations.

This appendix applies to hazardous material in quantities at or below "Allowable On-site Transfer Limits" (as noted below). On-site transport in quantities exceeding these limits required a work control document; or Only Jefferson Lab's Industrial Hygiene Department, Radiation Control Department, or Shipping and Receiving Department can authorize off-site hazardous material shipment of any quantity.

The following hazardous materials have additional requirements:

• Radioactive Material - see ES&H Manual Chapter 6310 Protection from Ionizing Radiation
• Hazardous Chemicals - in greater quantities than listed in the table below
• Biohazard Material - see ES&H Manual Chapter 6800 Appendix T4 Regulated Medical Waste Management

In-bound hazardous materials may be transported by Jefferson Lab staff from a vendor to the Lab when following the guidelines provided in Table 1 of this ESH Manual Chapter. This guidance is intended to meet the Department of Transportation's Materials of Trade exemption when items are for the sole purpose of supporting Lab business.
