Hazard Analysis

Hazard Analysis is the initial step in the process of identifying and evaluating potential

accidents in a facility. It is used to identify the hazardous chemical or radioactive material

in a process or facility and the energy sources and initiating events which could lead to

the potential consequences of an accident.

The objectives of Hazard Analysis are to (1) identify the hazards contained in a facility,

(2) perform final hazard categorization in accordance with Section 3 and Attachment 1,

based on hazardous material quantity identified in 4.1.1.a and energy sources and

initiating events identified in 4.1.1.b (preventive and mitigative features are not to be

considered in hazard categorization), (3) provide an overall assessment of the

importance of the various hazards, (4) identify occupational hazards and related DOE

prescribed standards, and (5) characterize and analyze the remaining non-routine

hazards that are unique and representative hazards to be analyzed in the SAR. To

accomplish these objectives, each facility preparing a SAR must perform a Hazard

Analysis as a means of fulfilling the requirement of DOE Order 5480.23, Section 8.c.

Hazard Analysis consists of collecting and integrating four interrelated sets of

information:

Hazardous Material Quantity, Form, and Location

Energy Sources and Potential Initiating Events

Preventive Features

Mitigative Features.

Hazardous Materials Quantity, Form, and Location

4.1.1.a

Hazard Analysis identifies the hazardous chemical and radiological materials at risk in

the facility. The quantity of material is assumed to be the maximum inventory

permitted to be processed or present in specific locations in the facility. This quantity

is generally determined from either process flow information or existing facility

operating experience. Examples of material form would include powder, metal (large

pieces or shavings), sludge, gas, solid waste, or liquid. Location indicates the part of

the building, glovebox, or process line in which the hazardous material is present.

Occupational hazards, including common industrial hazards, should be identified, and

the applicable DOE-prescribed OSH regulations, standards, and analyses should be

referenced in the SAR.

4.1.1.b

Energy Sources and Potential Initiating Events

Hazard Analysis then identifies potential energy sources and potential initiating events

which could affect the hazardous material and lead to a release of material or other

occurrence. Such events include internally initiated events (e.g., explosions and fires),

process-initiated events (e.g., spills or improper material transfers), and externally
