BIO/RAD Decontamination

Decontamination in commercial and industrial facilities should only be handled by Occupational Safety and Health Administration (OSHA) Hazardous Waste Operations and Emergency Response (HAZWOPER) trained professionals in the applicable decontamination procedures in addition to following EPA regulations and guidelines. OSHA has clear guidelines for workers and supervisors performing these services.  These guidelines address Chemical, Biological, Radiation, Radiological/Nuclear, and Explosive Clean Up and Decontamination services. It is also required under Federal and State law that the decontamination company’s employees and supervisors have a valid OSHA HAZWOPER certificate and annual refresher. The company should also be familiar with proper methods of disposal and any additional State and Local laws concerning the disposal of hazardous materials.

Capital Energy Group, LLC (CEG) utilizes HAZWOPER trained and certified personnel under normal ongoing operations and emergency circumstances for chemical, biological, and radiological decontamination. Each project undertaken by CEG also includes HAZWOPER Certified Safety personnel and Industrial Hygiene professionals offering a myriad of skillsets unique to the industry and individual project requirements.

CEG believes that following the hierarchy of controls as recommended by NIOSH is important to eliminate exposure and protection of our employees, the community, and stakeholders. The five rungs of the Hierarchy of Controls: elimination, substitution, engineering controls, administrative controls and personal protective equipment. The hierarchy is arranged beginning with the most effective controls and proceeds to the least effective. In a decontamination situation we often have to start with Elimination and Engineering control, and that is where our proprietary contaminate encapsulant and chlorine dioxide gas decontamination technology excels.

CEG can provide selected area decontamination and full facility decontamination under negative pressure enclosures with specified PPE step off control areas, showers, and air lock systems.

Biological Decontamination Services
CEG provides biological decontamination services for routine, single-time events, and emergency situations and declarations. CEG specializes in contamination prevention and decontamination response for both new and existing facilities. Our chlorine dioxide gas technology allows for the complete decontamination of your facility all at once, with minimal equipment and minimal downtime. Our gaseous systems provide the ability to achieve complete distribution and a thorough penetration of chlorine dioxide to each and every surface within your facility, including microscopic cracks, and HVAC systems to deliver an extremely high level of decontamination, something other agents such as vapors, mists, and fogs cannot promise. Our chlorine dioxide is safe on materials and leaves no post treatment residuals.

CEG follows all requirements of OSHA’s standards for bloodborne pathogens, respiratory protection, and hazard communications.

Radiological Decontamination Services

CEG’s radiological decontamination service utilizes a process to reduce or remove radioactive contamination to reduce the risk of radiation exposure to personnel. The removal of contamination from occupied areas, equipment and personnel is important to maintain an ionizing radiation dose as low as reasonably achievable (ALARA). Decontamination also reduces the spread of contamination to uncontrolled areas, personnel and equipment.

Decontamination is accomplished by cleaning and or treating surfaces to reduce or remove the contamination. CEG uses chemical, mechanical, and strippable coating operations to decontaminate equipment in Commercial Nuclear and Department of Energy (DOE) Legacy Waste Facilities under three basic protective measures; time, distance, and shielding.

CEG’s Proprietary Encapsulant
DBC-1400. A water based, non-toxic, encapsulant developed by CEG for encapsulating airborne contaminates, fixing contaminates to surface material, and creating an impermeable barrier between contaminates and the environment.  With efficiency in mind, CEG also designed DBC-1400 to be a single application coating and replace the need for two-part epoxy systems allowing for timely applications during critical need situations. Our process and product has been approved for use and used by the DOE, DOD Atmospheric Threat Protection Agency, and the commercial nuclear industries.
DBC-1400 General Properties

A decontamination barrier coating that is applied over contaminated surfaces to attract and bind surface and permeated contaminants.  The coating migrates into the micro-voids of the surface and upon curing, locks the contaminants into and beneath the coating matrix.


  • Control of airborne radiological contamination
  • A fixative for radiological contamination on structures to be demolished
  • As an engineering control for radiologically contaminated areas lowering PPE requirements
  • Control of airborne contaminates (i.e. beryllium, silica, asbestos, and lead)
  • Fixative for hazardous residuals on structures to be demolished
  • Asbestos encapsulant for abatement activities and clearance monitoring
  • Emergency Response to radiological and or hazardous waste spills (mitigating or preventing migration of contaminates)
  • Controlling airborne and migration of any regulated particulate
  • As an encapsulant fixative for any regulated related particulate
DOE Legacy Waste Manhattan Project Sites

East Tennessee Technology Park (K-25) B1420 Uranium Recovery Facility Reindustrialization Project.

  • Applied to the surfaces of contaminated material and equipment for contamination control during waste packaging operations
  • Utilized as a fixative for residual Uranium contamination prior to final survey

Oak Ridge National Laboratory B3505 Metals Recovery Facility Hot Cell Demolition

  • Applied to two 30’ long concrete exterior trench walls contaminated with 50-100K dpm of PU, U, and MAFP which allowed for open air demolition
  • Applied to 5 Concrete 20’ high Hot Cells contaminated with >500k dpm of PU, U, and MAFP which allowed for open air demolition
  • Applied to the contaminated surface of demolition equipment to mitigate the spread of contamination during relocation

Savannah River Site B322-M Hot Cell Demolition

  • Applied to concrete Hot Cells contaminated with >500k dpm of PU, U, and MAFP which allowed for open air demolition
  • Used to fog the inside of contaminated Hot Cell exhaust ducting to facilitate in safe removal, size reduction, and disposal

Rocky Flats Environmental Technology Site B701, B707, B708, B776, B771

  • Utilized as an encapsulant for open air removal of more than 100k ft2 of exterior transite with contamination levels exceeding 100k dpm of PU
  • Utilized on the interior of gloveboxes prior to segmentation and disposal
  • Utilized for the control of beryllium contamination inside B707 modules. After the application of DBC-1400, beryllium controls were lifted
  • Utilized in the unexpected discovery of PU levels > 100 dpm in B701 warehouse during floor shaving operations. Activities levels were reduced below background after application of DBC-1400
