- At Jefferson Lab there is the potential for oxygen deficiency hazards (ODHs) due to cryogens, compressed/solidified gases, clean-agent fire suppression systems, and/or any gas with the potential capability to drive oxygen content downward. This ODH Control Program provides procedures for determining:
- when an ODH Safety Review or ODH risk assessment is required · ODH classifications and the associated engineering and administrative controls
- training and medical exclusions to facilitate worker and equipment safety
- the appropriate emergency response
- Jefferson Lab considers ODH to be a hazard issue and as such requires training in accordance with Table 1 below. This document complies with applicable federal, state, and local requirements outlined in ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List.
- This document describes responsibilities and expectations associated with the following cryogens used at Jefferson Lab:
- helium
- nitrogen
- argon
- hydrogen
- oxygen
- Liquid air is not used in significant quantities at Jefferson Lab, but can be produced as an unwanted by-product by the interaction of air with the surface of exposed piping colder than 80 K. A constituent of liquid air is liquid oxygen. Any contact between liquid oxygen and petroleum products must be avoided.
