Destree Consulting, Inc. performed an on-site assessment of this facility and designed a custom training program to achieve regulatory compliance and effective emergency response capabilities for a municipal water treatment facility using and storing tons of liquefied Chlorine (Cl2) gas.  HAZWOPER, Respiratory Protection, Emergency Action Plans, Permit Required Confined Spaces, Control of Hazardous Energy were some of the regulatory compliance issues addressed by this consulting project and resulting training plan of action.  Use of proper CPC (Chemical Protective Clothing), PPE (Personal Protective Equipment), PRPE (Personal Respiratory Protective Equipment), Hazardous Atmosphere Monitoring Equipment, Incident Command, Coordination with local Municipal Emergency Responders and a variety of related prevention and emergency response aspects were addressed in this consulting and training project onsite.  Hazardous Materials at this facility included Chlorine (Cl2) liquefied gas, Anhydrous Ammonia (NH3) liquefied gas, Aqua Ammonia (NH3) 20%, Hydrofluosilicic Acid (H2SiF6), Hydrofluoric Acid (HF), Hydrochloric Acid (HCl), Hydrogen Sulfide (H2S) and related concentrated acids and caustics.


Onsite Health and Safety Officer Services - Extreme Hazard Chemicals - Hazardous Waste Incinerator Services Facility, Ohio.

Multi-faceted remediation project at a Hazardous Waste Incinerator in Ohio.  

Project initiated after a tragic waste worker fatality from burns – from the CSB description “According to company officials a flash fire occurred when workers were splitting a large solid waste drum of hazardous flammable inorganic material into smaller storage drums.‘

After this tragic incident in 2011 our company was brought in as the lead Health Safety Security, flammable hazards and confined space rescue RIT team Safety and Health Officer onsite at this highly hazardous operation.  Project included repackaging extreme toxicity material, explosive peroxide forming material, highly flammable liquid material in multiple drums using remote opening, manipulating robotics in a completely purged chamber filled with nitrogen gas until oxygen levels were well below 1.0% by volume.  Materials successfully handling during the project were: MAE ETCHANT; PERCHLORIC ACID/CERIUM AMMONIUM NITRATE; METHYL BROMIDE IN METHANOL; COOLING TOWER SLUDGE; SLURRY WASTE; TECHNICAL GRADE TEAR GAS POWDER; NYSTEAD REAGENT; PINANEBORANE; and EXPLOSIVES (material ID is RESTRICTED INFORMATION}

WC Environmental Works at U.S. Air Base

Author: William Charles Ltd.
Date posted: 7/22/2009


Paul Ezop and Jim Ward of WC Environmental Services (WCES), in conjunction with Focus Environmental of Rockford and Keith Destree, CSP of Destree Consulting, Inc. of Joliet, IL conducted a gas cylinder remediation project at Wright-Patterson Air Force Base (WPAFB) in Dayton, OH, in June. WPAFB is in many measures the largest, most diverse and organizationally complex base in the US Air Force. It is also one of the largest research and development facilities in the United States.  The base has used a numerous array of hazardous chemicals since they began operations during the World War I era.

The remediation process included gas cylinders containing Hydrogen Bromide (HBr) and Hydrogen Fluoride (HF). Both HBr and HF, if left unused over a long period of time, can separate, build pressure and eventually explode. Pressure build up was not the only concern; these chemicals are very corrosive and toxic by nature. SCBA’s (self-contained breathing apparatus) and tight level-B chemical suits were used to complete the exercise and keep the team safe. The cylinders were remotely accessed by drilling a hole through the side wall. This was accomplished by submerging the cylinders under a caustic chemical solution in association with a specially devised glove box. This process safely vented the cylinders and neutralized chemicals at the same time.

The WCES team also remediated a cylinder of Tetrafluorohydrazine (a stage 3 rocket fuel). Tetrafluorohydrazine over a period of time becomes explosive as well. This cylinder was robotically placed in a cylinder casket by WPAFB Explosive Ordinance Division with the WCES team as back-up. Once stabilized, the cylinder was left at WPAFB for future destruction.
