HAZARD ANALYSIS. The determination of material, system, process, and plant

characteristics that can produce undesirable consequences, followed by the assessment of

hazardous situations associated with a process or activity. Largely qualitative techniques

are used to pinpoint weaknesses in design or operation of the facility that could lead to

accidents. The hazards analysis examines the complete spectrum of potential accidents

that could expose members of the public, onsite workers, facility workers, and the

environment to hazardous materials. [DOE-STD-3009-94]

HAZARD CATEGORIES. The consequences of unmitigated releases of radioactive

and/or hazardous material are evaluated and classified by the following hazard

categories:

A. CATEGORY 1. The hazard analysis shows the potential for significant offsite

consequences.

B. CATEGORY 2. The hazard analysis shows the potential for significant onsite

consequences.

C. CATEGORY 3. The hazard analysis shows the potential for only significant

localized consequences. [DOE O 5480.31] [EH62dd1]

268.

HAZARD CLASSES. Non-nuclear facilities will be categorized as high, moderate, or

low hazards based on the following:

A. High - hazards with a potential for onsite and offsite impacts to large numbers of

persons or for major impacts to the environment;

B. Moderate - hazards which present considerable potential onsite impacts to people or

the environment, but at most only minor offsite impacts, and;

C. Low - hazards which present minor onsite and negligible offsite impacts to people

and the environment.

[DOE O 5481.1B]

HAZARDS CONTROLS. Measures to eliminate, limit, or mitigate hazards to workers,

the public, or the environment, including

A. Physical, design, structural, and engineering features;
