Activity-Level Hazard Analysis Requirements

integration is necessary. The NCSE provides important assumptions and conclusions that

must be reflected within DSAs regarding the initiators for a criticality event, as well as the

necessary controls.

Natural Phenomena Hazard Assessment. DOE O 420.1 also requires a Natural Phenomena

Hazard Assessment (NPH). NPH assessments involve an assessment of the likelihood of future

natural phenomena occurrences and the response of facility systems, structures and components

to a design basis NPH event. The resulting information is used as important assumptions within

safety analysis or PrHA to evaluate accident scenarios and consequences. Therefore, NPH

assessments should be coordinated through teaming efforts with hazard/accident analysts.

Various Regulations on Specific Hazards (e.g., Beryllium Hazards Assessment). A number

of regulations have hazard analysis requirements that are specific to certain activities, hazardous

conditions or specific substances. Appendix A lists several of these regulations. One example is

the Chronic Beryllium Disease Prevention Program Plan as required by 10 CFR 850. This

requires identification of the quantity and form of beryllium materials and their locations, as well

as an assessment of possible beryllium exposures from planned activities. Much of the hazards

information needed to meet hazard-specific regulations may be available in existing safety

analysis, PrHA documents, airborne monitoring data, or other previous hazard assessments

conducted at a facility.

Activity-Level Hazard Analysis Requirements

A third group of hazard analysis activities can be characterized as focusing on worker related

hazards associated with specific activity tasks. These include the following sources:

Worker Hazard and Risk Analysis of Hazardous Waste Cleanup Activities (29 CFR 1910.120

and 1926.55, "Hazardous Waste Operations and Emergency Response")

Activity Hazard Analyses (DOE O 440.1A, "Worker Protection Management")

Analysis of Occupational Radiation Hazards (10 CFR 835, "Occupational Radiation

Protection")

Each of the hazard analysis requirements reflected in this group is an integral part of work

planning, which feeds into the preparation of hazardous and radiation work permits, Health and

Safety Plans, Industrial Hygiene Plans and overall work packages and documentation. These

activities have a different emphasis than facility-level hazard analysis, since they are primarily

focused on worker protection. As such, activity-level hazard analysis addresses the hazards

associated with individual job functions and tasks.

In spite of these differences, there is an important link between facility and activity level hazard

analysis requirements in terms of the flow of hazards information and data. For example, facility-

level information and assumptions related to hazardous material inventory (e.g., quantity, form

and location) feed into activity hazards analysis in order to help identify the range of potential

hazards a worker may encounter while carrying out his/her duties (e.g., valve maintenance on a

high pressure liquid hazardous waste line). Conversely, assessment of work-related hazards from

activity-level analysis may yield insights into hazards that have not been adequately covered

within facility-level analysis and as such may warrant further evaluation by a PrHA or DSA.

HAZWOPER Risk Assessment. OSHA (29 CFR 1910.120) requires that a health and safety

plan (HASP) be prepared for hazardous waste cleanup operations. The HASP must involve a

hazard/risk assessment of planned activities to identify any conditions that pose significant
