Appendix T3 ODH Emergency Response Procedure |
||
|
|||
Jefferson Lab recognizes
that the physical and mental condition of individuals exposed to an oxygen deficient environment rapidly deteriorates and requires immediate action. This appendix outlines the procedure for responding to an oxygen
deficiency event and/or an oxygen deficiency hazard (ODH) alarm.
The ODH Emergency Response Procedure outlined in this appendix
applies to individuals who are not trained or qualified to perform emergency
response activities. Only individuals, trained in emergency response, have priority
access to buildings and are authorized to respond according to their
training.
This appendix is written in
coordination with ES&H
Manual Chapter 6540 Oxygen Deficiency Hazard Control Program. All relevant
content within the chapter applies to the procedure outlined in this appendix.
NOTE: Emergencies
related to cryogens
are discussed in ES&H
Manual Chapter 6550 Appendix T2 Emergency Response to Cryogens. Emergency
response for other situations is discussed in ES&H Manual Chapter
3510 Emergency Response Activities. |
NOTE: Management
authority may be delegated to a task qualified Jefferson Lab employee at the
discretion of the responsible manager.

immediately even if the ODH
alarm does not activate. |
