1.2.1.2 Safety Analysis Summary
The handling of excess chemicals exposes the workers and the environment to a variety
of potential hazards. Potential hazards include the possibility of inhalation, ingestion, and/or
absorption of toxic, hazardous, or noxious materials. There are various chemicals in the
Building 991 Complex that could present this hazard. Other potential hazards include exposure
to unknown or unmarked materials (presently none identified), and exposure to other types of
chemical hazards (e.g., batteries). Precautions are required by facility personnel during the
performance of this activity. These include ensuring proper procedures are followed during the
characterization, treatment, and disposition of any excess chemicals; that personnel are properly
trained; Health and Safety Practices are followed; that the material is placed in approved storage
locations and is packaged properly; the quantities of chemicals is limited if possible; and that
personnel protective equipment is worn as required.
1.2.2 Construction
1.2.2.1 Activity Description
This activity encompasses upgrades of various Building991 Complex SSCs,
modification of various SSCs, removal of fured SSCs from the Complex, and addition of various
SSCs. When construction of specific facility SSCs is required, the Work Control process will be
implemented to assess the scope of hazards and define the approach to performing the task. The
extent ‘of assessment is graded based upon anticipated involvement with radiological and
hazardous materials, and the characteristics of the specific construction activity. Work Control
assessment results in a set of controls that are defined in the IWCP package. Operation of any
process involving hazardous materials is not authorized through this activity.
1.2.2.2 Safety Analysis Summary
Construction activities predominately involve standard industrial hazards such as high
energy equipment, sparking, and compressed flammable gases. Potential hazards associated
with this activity include thermal energy (e.g., welding), pressure sources (e.g., compressed
gases or hydraulics), and/or kinetic energy (e.g., vehicles, rotating cutting tools). Construction
activities may occur in areas used for storage of nuclear materials (e.g., Category ID1 SNM,
radioactive wastes). Activities are evaluated individually in work packages prior to start of
construction. Results of evaluations may dictate that Material-At-Risk (MAR) be removed from
construction areas or that implementation of special controls are warranted.
1.2.3 Generation of Waste
1.2.3.1 Activity Description
This activity encompasses the generation of waste in the Building 991 Complex (LLW
from filter plenums, potential Toxic Substance Control Act (TSCA) waste (e.g., polychlorinated
biphenyls (PCBs)) in the facility, RCRA waste (nickel cadmium batteries in RCRA satellite
