DOE-STD -3009-94
3.3.1 Methodology
This section presents the methodology used to identify and characterize hazards
and to perform a systematic evaluation of basic accidents.
3.3.1.1
Hazard Identification
This subsection identifies the method used by analysts to identify and
inventory hazardous materials and energy sources (in terms of quantity, form,
and location) associated with the facility processes or associated operations
(e.g., waste handling). This methodology first identifies sources of
referenced information that are not an integral part of the DSA hazard
identification. Possible sources of such information include fire hazard
analyses, health and safety plans, job safety analyses, occurrence reporting
histories, etc.
The DSA covers worker safety issues related to hazards in processes and
associated activities. It is not the intention of the DSA to cover safety as it
relates to the common industrial hazards that make up a large portion of basic
OSHA regulatory compliance. It is important not to expend DSA resources on
those hazards for which national consensus codes and/or standards (e.g.,
OSHA regulations) already define and regulate appropriate practices without
the need for special analysis. As noted in this Standard's definition of
"hazard," standard industrial hazards are identified only to the degree they are
initiators and contributors to accidents in main processes and activities. For
example, worker electrocution from electrical wiring faults is not a DSA issue.
However, the existence of 440 volt AC cabling in a glovebox would be
identified as a potential accident initiator for a scenario (i.e., fire) involving
hazardous materials.
The distinction cited in the previous examples makes careful identification of
hazards covered in the DSA essential so that potential worker hazards are not
overlooked. As part of the identification process, the basis that was used in the
hazard screening to remove standard industrial hazards or insignificant hazards
from further consideration needs to be presented as well. For these cases, the
DSA hazard analysis process interfaces with other programs such as specific
topics of OSHA compliance or general industrial safety. These interfaces must
be identified. Some of these compliance issues, while not presented in the
DSA as such, may be a portion of a safety management program committed to
by the facility. An example of this is the Health and Safety Plans required by
OSHA in accordance with the Hazard Waste Operations and Emergency
Response program. This could be one element of the "plans, procedures, and
training for governing operations involving radioactive and hazardous waste"
specified in Section 9.3, "Radioactive and Hazardous Waste Management
Organization."
This subsection also indicates the sources from which information was
obtained, such as flowsheet inventories, maximum historical inventories,
vessel sizes, contamination analyses, etc. The interpretation of the data used to
