Worker Safety

This section summarizes the major features protecting workers fro m the

hazards of facility operation, exclusive of standard industrial hazards.

Summary products germane to worker safety typically include:

General overview of worker safety in terms of SSCs and

administrative features.

Identification of any safety-significant SSCs and SACs.

Identification of any safety management programs that will be

assigned TSR coverage in the form of administrative controls for

adequate worker safety.

General prioritization of the features needs to be included and expressed in

terms o f the magnitude of process hazard, number of potentially affected

employees, pertinent aspects of operation history, and projected lifetime of the

process. Only a summary level discussion is required, not a detailed

discussion or defense of the prioritiza tion logic. The safety features to be

addressed in this section fall into one of three categories:

Structures, systems, and components.

Specific administrative controls.

Administrative features..

This subsection is derived from examining the raw information in the hazard

evaluation tables (see Table 3-1 for example) and distilling it into a clear

overview of worker safety features at the facility. This presentation may use

relevant accidents to frame and focus the discussion, but need not duplicate the

ha zard evaluation already provided in or appended to the DSA in tabular form.

If the basic function of a worker safety feature has already been discussed in

Section 3.3.2.3.2, "Defense in Depth," that feature may simply be identified by

name and referenced.

Identify structures, systems, and components as safety-significant SSCs where

appropriate. As a general rule of thumb, safety-significant SSC designations

based on worker safety are limited to those systems, structures, or components

whose failure is estimated to result in a prompt worker fatality or serious

injuries to workers or significant radiological or chemical exposures to workers

(see definition of safety-significant SSCs for further clarification). Inadvertent

worker exposure to materials from breached nuclear storage packages during

inspections or handling may fit this description.

Identify specific administrative controls important to safety that are needed to

prevent or mitigate an accident scenario as appropriate. In general, SAC

designations based on worker safety are limited to those administrative

controls that would have been safety-significant had that safety function been

provided by a safety-significant SSC. The established hierarchy of hazard

controls requires that engineering contro ls with an emphasis on safety-related
