DOE-STD-3006-95

3.13 Functional Areas. Discrete groups of related safety and support programs.

3.14 Graded Approach. The process by which the level of analysis, documentation, and actions

necessary to comply with a requirement are commensurate with: (1) the relative importance to safety,

safeguards, and security; (2) the magnitude of any hazard involved; (3) the life cycle stage of a

facility; (4) the programmatic mission of a facility; (5) the particular characteristics of a facility;

and, (6) any other relevant factor.

3.15 Hazard. A source of danger (e.g., material, energy source, or operation) with the potential

to cause illness, injury, or death to personnel or damage to a facility or to the environment (without

regard for the likelihood or credibility of accident scenarios or consequence mitigation).

3.15.1 Hazard Categories. The consequences of unmitigated releases of radioactive and/or

hazardous material are evaluated as required by DOE 5480.23 [10 CFR 830.110] 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 5480.23 [10 CFR 830.110].

DOE-STD-1027-92 and DOE-EM-STD-5502-94 contain additional information on methods and

criteria for determination of Hazard Categories.

3.15.2 Hazard Classes. Non-nuclear facilities will be categorized as high, moderate, or low

hazards based on the following:

High - hazards with a potential for onsite and offsite impacts to large numbers of persons or

for major impacts to the environment;

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

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

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

environment. (DOE 5481.1B)
