Projects: Railroad Derailments
August 2020: Tempe Train Derailment
GrayMar received emergency response call to respond to train derailment in Tempe Arizona. GrayMar was the lead responder and provided full turnkey emergency response clean-up efforts. Initial response involved vacuuming water from storm drain to assist the fire department with their fire suppression activities. GrayMar arranged for the mobilization of portable rest rooms, potable water, site security personnel as well as security fencing to secure the project site. GrayMar set up safe perimeter around the vast exclusion zone to ensure appropriate safety for the community and responders. GrayMar provided labor and equipment to remove burned debris from lake for placement into 40–yard bins. GrayMar deployed three watercraft vessels to strategically place approximately 2000 feet of hard containment boom. GrayMar personnel directed and performed full skimming operations for the entire body of water achieving the successful removal of large volumes of bulk debris. In addition, our crews pumped hundreds of thousands of gallons of water containing unwanted product/debris from various areas of the lake including the east side of the dam into multiple staged frac tanks. Our skilled equipment operators used excavating equipment with buckets/thumbs to remove debris that flowed over the dam gates. As part of the response activities, at the conclusion of the project, GrayMar provided pertinent close out project activities including sampling, transportation and disposal of all generated waste materials from the project.
One critical part of the derailment event was the need to transfer liquid material from damaged tanker cars to prevent further hazardous conditions. GrayMar provided tank car specialist, management oversight and equipment for the high–profile transfer of cyclohexanone from four damaged tanker cars. The cyclohexanone material was successfully transferred utilizing a nitrogen blanket and specialty hoses into awaiting tanker units for final transfer into staged and secondary contained frac tanks.
