Flash Hazard Analysis

DOE-HDBK-1188-2006

255.

FLASH HAZARD ANALYSIS. A study investigating a worker's potential exposure to arc-

flash energy, conducted for the purpose of injury prevention and the determination of safe work

practices and the appropriate levels of personal protective equipment. [NFPA 70E]

256.

FLASH PROTECTION BOUNDARY. An approach limit at a distance from exposed live

parts within which a person could receive a second degree burn if an electrical arc flash were to

occur. [NFPA 70E]

257.

FLASH SUIT. A complete flame resistant clothing and equipment system that covers the entire

body, except for the hands and feet. This includes pants, jacket, and bee-keeper-type hood

fitted with a face shield. [NFPA 70E]

258.

"FLOOR-LEVEL" PROCEDURES. Detailed instructions used by technicians, researchers,

and other workers to directly accomplish work activities or tasks. [DNFSB mandated] [DOE

G 450.4-1B]

259.

FULL-SCOPE SIMULATOR. A simulator incorporating detailed modeling of systems of the

reference facility with which the operator interface in the control room environment. The control

room operating consoles are included. Such a simulator demonstrates expected facility

response to normal and abnormal conditions. [DOE Glossary and DOE O 5480.20A]

260.

FUNCTION. An action or activity undertaken by a DOE employee in performing or

contributing to performance of work in compliance with component 3 of DOE P 450.4,

SAFTY MANAGEMENT POLICY. This component defines five core functions for

integrated safety management, each of which includes several derivative functions which are to

be applied with a degree of rigor appropriate to the type of activity and hazards involved.

[DOE M 411.1-1B]

261.

FUNCTION. The capability of structures, systems, and components to perform their intended

mission. Maintaining function after a natural phenomena hazard (NPH) occurrence is required

by DOE O 4330.4A for structures, systems, and components important to safety, and to

minimize property losses based on cost benefit considerations. Maintaining function such that -

programmatic objectives are achieved is not required by this Order, but is commonly a goal for

NPH design and evaluation. [EH62dd1]

262.

FUNCTIONAL UNIT. A logical and systematic group of property that is necessary to

support the site mission. A functional unit must be described in a breakdown structure for each

site in order that it be properly identified and managed. Functional units will vary in size and

scope within sites and from site to site, depending on the type or types of activities being carried

out. A functional unit will often comprise a total facility (e.g., laboratory, production plant, or
