Pocket Guide 2021 5.12 Caulks, Paints, and Coatings 5.12.1 Caulks are used to seal joints in components, windows, and structures for noise mitigation, thermal insulation, and water penetration. The versatility of caulks allows them to be used in numerous applications over a wide range of temperatures. The physical properties of caulk are dependent upon the materials used by the manufacturer; over time caulk may remain soft and pliable, or may become brittle and crumble easily.

A. Some of the materials commonly used in caulks include asbestos, lead, and PCBs. Sampling of many of the caulks at Fort Calhoun has been performed.

B. If your work activity involves disturbing caulk, the Work Package should identify if asbestos, lead, and/or PCBs are present and the appropriate controls to disturb the caulk. If you should encounter caulk that is not identified in your Work Package, STOP and inform your Supervisor and Safety. An evaluation of the caulk will be performed to determine the appropriate actions to properly handle the caulk.

5.12.2 Paints and coatings are used to protect a substrate (i.e., metal, concrete, any material that the paint or coating is applied to) from corrosion and to present a visually pleasing appearance. Paints and coatings are presumed to contain lead until laboratory analysis of the paint has been performed.

5.12.3 If your work activity involves disturbing paint or coatings, the Work Package should identify if lead and/or PCBs are present and the appropriate controls to disturb the paint.

5.13 Changing Conditions, Eyes on Path 5.13.1 All personnel are responsible for maintaining their Eyes on Path as conditions will change on a continuous basis for the duration of the Fort Calhoun Deconstruction Project as Structures, Systems, and Components (SSCs) are removed. These changes can occur at any time, and require you to constantly evaluate your work area to ensure that conditions are acceptable for you to perform your work safely.

5.15 Compressed Gasses (§29 CFR 1910.101) 5.15.1 Compressed gases present a unique hazard. Depending on the particular gas, there is a potential for simultaneous exposure to both mechanical and chemical hazards. If the gas is flammable, flash points lower than room temperature compounded by high rates of diffusion present a danger of fire or explosion. Additional hazards of reactivity and toxicity of the gas, as well as asphyxiation, can be caused by high concentrations of even normally benign gases such as nitrogen. Since the gases are contained in heavy, highly pressurized metal containers, the large amount of potential energy resulting from compression of the gas makes the cylinder a potential rocket or fragmentation bomb.

5.15.2 Compressed gasses will be used in accordance with References 6.1.26 -

FCSI-SAF-103 FCSI Page 16 of 67 Rev. 1 Reference Use FCS Deconstruction Project Health and Safety Plan (HASP)

PCBs are either oily liquids or solids that are colorless to light yellow. Some PCBs can exist as a vapor in air. PCBs have no known smell or taste. Many commercial PCB mixtures are known in the U.S. by the trade name Aroclor. PCBs have been used as coolants and lubricants in transformers, capacitors, and other electrical equipment because they dont burn easily and are good insulators. The EPA has classified PCBs as a probable human carcinogen.

5.61.2 PCBs are known or presumed to be present in:

• Caulks

• Electrical Equipment (i.e., cable, capacitors, circuit breakers, electric motors, electromagnets, reclosers, switches, voltage regulators and voltage regulator enclosures)

• Fluorescent light ballasts

• Heat transfer and hydraulic systems

• Paints and coatings

• Transformer oil

• Voltage Regulators 5.62 Potassium Chromates 5.62.1 K2CrO4 (Potassium Chromate) and / or K2Cr2O7 (Potassium Dichromate) was used as a corrosion inhibitor in the Component Cooling Water (CCW)

System and the Turbine Plant Cooling Water (TPCW) System. The use of K2CrO4 / K2Cr2O7 was discontinued in the 1990s; system flushes were performed to remove the K2CrO4 / K2Cr2O7 from these systems at that time.

Analytical testing has confirmed that K2CrO4 / K2Cr2O7 from is not present in the CCW cooling water; however, industry experience indicates that the potential for residual K2CrO4 / K2Cr2O7 as a yellow or white-colored crystalline powder or caked solid exists in dead legs, low-flow areas, and low points of these systems.
