ES&H Manual



6610 Appendix T6

Response to Chemical Over-Exposure



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


1.0            Purpose


Jefferson Lab requires that qualified chemical workers read and follow the recommended emergency and first aid procedures provided on a chemical’s material safety data sheet (MSDS). This appendix describes minimal response procedure steps for an incident exposure involving a chemical.


2.0            Scope


This appendix provides a minimum response procedure to use if the MSDS is not available; requirements to initiate medical assistance; and clean-up recommendations. 


This appendix’s process steps are performed in coordination with ES&H Manual 6610 Chemical Hygiene Program.


NOTE: Jefferson Lab does not have on-site fire brigade resources, but has written agreements from the City of Newport News to provide emergency services through its 911 system. These include emergency medical response and transport, emergency technical rescue, and hazmat incident response. Letters confirming these services are on file with the Emergency Manager.
