Fire department sources tell Action News that six DDOT buses were destroyed in an accidental fire, at the Coolidge bus yard this morning.
Detroit firefighters were called to the two alarm fire at the DDOT maintenance facility early Wednesday morning that took several hours to put out.
The facility is located on the city's west side on the 14000 block of Schaefer where Senior Chief Mike Herron says the buses were engulfed in flames and the roof collapsed above them.
Herron says the buses were contained by a firewall to separate them from the rest of the fleet.
Firefighters used foam inside the building as there were no hydrants available. "I am very proud of how the men responded," said the chief, "We had a limited supply of water."
There are reports that the sprinkler system inside the building was not working.
Black smoke from hundreds of gallons of diesel fuel blew toward nearby homes. Authorities monitored the air quality and were concerned over smoke damage. They are uncertain if hydraulic fluid may have caught fire.
Officials do not believe bus service will be affected today as firefighters were allowing drivers into the yard to access their buses.
One firefighter is reported to have slightly injured his shoulder while pulling a hose across the yard.
Dozens of fire trucks as well as a HazMat team were on the scene.
Detroit spokesperson Steve Serkaian tells Action News that the buses, worth $350,000 each are insured. Serkaian says the damage would have been much worse had the employees not acted so promptly. "Several mechanics and bus drivers put themselves at risk to drive other buses through the black smoke so they would be safe."

Blastcrete Equipment introduce new mine mate machine
Blastcrete Equipment has introduced the Mine Mate, designed to mix and pump concrete material for underground mine sealing and stabilisation, grouting and various other shotcrete applications. The Mine Mate is a convenient solution when ready-mix concrete is not an option. Featuring Blastcrete’s X-10 ultra-high pressure swing tube pump, it is a highly productive and reliable machine that’s also easy to operate and maintain.
The Mine Mate uses the wet-mix shotcrete process. It was created at the request of several customers seeking a machine to apply shotcrete in underground coal applications. In contrast to the dry shotcrete (gunite), the wet shotcrete process minimises dust emissions and improves visibility making it much safer, particularly for underground use. Of compact configuration, the Mine Mate is designed for operation within a 1.2 m ceiling.
The Mine Mate includes Blastcrete’s X-10 76-mm, high-pressure swing tube pump, and a high shear continuous mixer. The unit is capable of mixing and pumping 9.2 m3/h and can handle aggregate up to 9.5 mm diameter. It can pump material in excess of 150 m, horizontally and vertically. Additionally, the hydraulic pump can run in reverse to eliminate line pressure from the delivery line should a hose plug.
The X-10 provides easy access for cleaning and maintenance. The receiving hopper of the pump is mounted with a heavy-duty hinge so that it can easily swing away from the swing tube section. The flat pack is held in place by four heavy-duty bolts so that the spare flat pack can quickly and easily be replaced.
Available power options include a V3,600, 50-kW Kubota water-cooled diesel engine or 37-kW electric motor with starter and disconnect. The machine can also be equipped with a material screw conveyor, with bin indicator for charging the continuous mixer. The Mine Mate’s X-10 is CE Certified, meeting European Union safety standards for equipment operation.

Flow Control Systems at the Paris Air Show
Marotta Controls, a leader in motion and flow controls, will present a wide range of mission-critical airborne systems, space flight components and capabilities at the 49th International Paris Air Show hosted June 20-26 in Le Bourget, France.
“The systems on display at the Paris Air Show have proven performance in extreme environments”
Marotta Controls will showcase its M-PACT family of reusable, cost-effective pneumatic solutions designed to boost the efficiency of critical military aircraft and weapon systems while reducing maintenance and logistics costs. Also on display will be the M-CONTROL suite of electronic control systems, which have been chosen by international customers for their superior performance ability in extreme military environments.
Marotta Controls’ airborne systems, components and electronic controls have been qualified for a variety of platforms including the F/A-18 Hornet, F-35 Joint Strike Fighter, E-2D Advanced Hawkeye, P-8A Poseidon, Small Diameter Bomb and chosen for the new Joint Air-to-Ground Missile (JAGM).
This year Marotta Controls is also highlighting its world-class space-flight qualified components for pressure regulation and flow control. These components have been supporting manned and unmanned spaceflight for more than 65 years, and support a wide range of programs including Falcon 1, Falcon 9, H2A, H2B, Delta II, Delta IV, ST-5, GOCE, Space Shuttle and the International Space Station.
“The systems on display at the Paris Air Show have proven performance in extreme environments,” said Michael J. Leahan, vice president and chief sales officer of Marotta Controls. “Our high-pressure pneumatic systems are qualified for combat environments, and our space-flight qualified components have been supporting manned and unmanned space flight for more than 65 years. We invite you to visit our stand at the Paris Air Show, Hall 3, Stand AB158, and hope you can take some time to talk to us about your needs and requirements for proven, reliable, state-of-the-art motion and flow control technologies.”

Oil, Gas Companies Injected Toxic Chemicals Into Ground, U.S. Report Shows
Fourteen oil and gas companies used 780 million gallons of hydraulic-fracturing products from 2005 and 2009, including toxic substances like benzene and lead, to extract gas from shale rock, according to a report by Democrats in the U.S. Congress.
More than 2,500 products containing 750 chemicals and other components were used, Representatives Henry Waxman, Edward Markey and Diana DeGette wrote in the report.
Hydraulic fracturing, or fracking, is a technique that involves injecting a mix of water, sand and chemicals into the ground to extract oil or gas. From 2005 and 2009, the 14 companies used fracking products containing 29 chemicals that are known or possible human carcinogens, regulated under the Safe Drinking Water Act for their risks to human health or listed as hazardous air pollutants, according to the report.
“In many instances, the oil and gas service companies were unable to identify these proprietary chemicals, suggesting that the companies are injecting fluids containing chemicals that they themselves cannot identify,” Democrats on the Energy and Commerce Committee said in an e-mailed statement yesterday.
The most widely used chemical in fracking during this period was methanol, a hazardous air pollutant, the report shows. The Democratic study was reported earlier by the New York Times.
“Hydraulic fracturing has opened access to vast domestic reserves of natural gas that could provide an important stepping stone to a clean energy future,” according to the report. “Yet questions about the safety of hydraulic fracturing persist, which are compounded by the secrecy surrounding the chemicals used in hydraulic fracturing fluids.”
Shale-Gas Output
Shale-gas output in the U.S. rose more than eightfold in the last decade as operators started fields in Pennsylvania, Arkansas, Louisiana, Montana and North Dakota. Increased supplies could help reduce the amount of energy the U.S. imports, the Energy Information Administration said in December.
President Barack Obama said last month the U.S. should tap its shale-gas deposits as part of a long-term plan to guarantee energy security. Shale gas may account for 45 percent of total U.S. gas output by 2035 compared with 14 percent in 2009, EIA data show.
