This week marks 20th anniversary of deadly chemical plant blast in Pennsylvania

conceptscience The destroyed Concept Sciences building and damaged other buildings in the Hanover Township industrial park.
Twenty years ago this week a chemical plant explosion in Pennsylvania killed five and injured six, becoming one of the first major investigations conducted by the newly established U.S. Chemical Safety and Hazard Investigation Board. The explosion occurred at Concept Sciences Inc., near Allentown, PA, on February 19, 1999. As a result of the explosion four Concept Sciences employees and the manager of an adjacent business were killed. Two Concept Sciences employees were injured, as were four people in nearby buildings. The explosion damaged ten buildings and several residences in the immediate area. The case study found that the explosion was most likely due to high concentration and temperature in a process vessel containing several hundred pounds of hydroxylamine, a potentially explosive chemical used in the manufacture of semiconductors. Concept Sciences' process safety management systems were insufficient to properly address the hazards inherent in its manufacturing process. The case study added...

CSB releases final report on June 2016 Pascagoula gas plant explosion

The U.S. Chemical Safety Board has released its final report of the June 27, 2016, investigation of an explosion and fire at the Enterprise Products Pascagoula Gas Plant in Pascagoula, MS. The CSB determined that the probable cause was a phenomenon known as thermal fatigue.  The CSB also issued recommendations to two trade associations and local emergency responders.   The incident occurred late in the evening on June 27, 2016, when a major loss of containment in a heat exchanger resulted in the release of methane, ethane, propane, and several other hydrocarbons. The hydrocarbons ignited, initiating a series of fires and explosions, which ultimately shut down the site for almost six months.  CSB Interim Executive Kristen Kulinowski said, “More than 500 gas processing facilities operate across the country and the use of similar heat exchangers is common. Extending the life cycle of equipment at these facilities requires more robust inspection protocols.  Operators shouldn’t...

Chemical Safety Board preliminary report links refinery blasts in Wisconsin and California to cracking unit failures

A preliminary report released this week by the Chemical Safety Board blames recent refinery explosions in Superior, WI and Torrance, CA on the inadvertent mixing of hydrocarbons with air inside the Fluid Catalytic Cracking Unit that found an ignition source, resulting in an explosion.   On April 26, 2018, an explosion (Figure 1) and subsequent fire (Figure 2) occurred at the Superior Refinery Company LLC refinery in Superior, Wisconsin (“Husky Superior Refinery”).1 The incident occurred in the refinery’s Fluid Catalytic Cracking Unit (FCCU). As a result of the explosion, thirty-six people sought medical attention, including eleven refinery and contract workers who suffered OSHA recordable injuries. In addition, a portion of Superior,2 Wisconsin was evacuated. Evidence collected to date suggests similarities with a previous investigation of the February 18, 2015 explosion at a refinery in Torrance, CA.   On Wednesday, February 18, 2015, an explosion occurred in the ExxonMobil Torrance, California refinery’s...

Shrapnel from explosion sets stage for huge Husky refinery fire in April

Rather than race to the scene, Superior, WI Fire Chief Steve Panger went straight to fire department headquarters when an April 26 refinery explosion rocked the community. Planning for an emergency response on the scale required that day had long been in place, he said.  “I knew we’d have callback crews of off-duty personnel reporting immediately,” Panger said. “My immediate job was to manage those crews and cover the fire stations emptied by the initial response to the blast.”  As the incident progressed and the stations were backfilled, Panger would move to the command post already set up by Husky Energy personnel. The explosion in a fluid catalytic cracking unit triggered an ongoing fire at the 38,000 bpd refinery that burned for the next eight hours, forcing an evacuation of Superior, population 27,000. Those residents were not allowed to return until the following morning. At the time of the blast, the...

CSB: "Significant lack of planning for flooding" cited in final report into August 2017 Arkema chemical plant fire near Houston

  Houston, TX, May 24, 2018: The U.S. Chemical Safety Board (CSB) released its final investigation report into the August 31, 2017, fire at the Arkema chemical plant in Crosby, Texas. In the days leading up to the incident, an unprecedented amount of rain fell at the plant due to Hurricane Harvey, causing equipment to flood and fail. As a result, chemicals stored at the plant decomposed and burned, releasing fumes and smoke into the air.    CSB Chairperson Vanessa Allen Sutherland said, “Our investigation found that there is a significant lack of guidance in planning for flooding or other severe weather events. Based on other government reports, we know that there is a greater likelihood of more severe weather across the country. As we prepare for this year’s hurricane season, it is critical that industry better understand the safety hazards posed by extreme weather events.”    The Arkema chemical plant...

Texas VFD confronts uncertain silo situation

Making a proper on-scene assessment of a silo fire that forced an evacuation around a Texas grain mill in September 2017 proved awkward, said Easterly Fire Chief Jim Redden. An auger opening at the base of a 120-foot-tall, 24-foot-diameter storage silo was the only access to the intense flames roaring inside. “Everybody thought the fire was in the very bottom,” Redden said. “But I could see smoke venting from the top of the silo. If the fire was buried under 35 feet of corn you shouldn’t be seeing that smoke.” All that corn encased within eight-inch concrete walls made it difficult for thermal imaging to detect where the bulk of the fire lay, he said. Despite feeding a continuous stream of water into the silo, Redden became increasingly worried about the potential for a grain dust explosion. Grain dust is a highly explosive substance that must be handled carefully. In 1977,...

CSB issues final report on Feb. 2015 refinery explosion in Torrance, CA

The U.S. Chemical Safety Board (CSB) released its final report into the February 18, 2015, explosion at the ExxonMobil refinery in Torrance, California. The blast caused serious property damage to the refinery and scattered catalyst dust up to a mile away from the facility into the nearby community. The incident caused the refinery to be run at limited capacity for over a year, raising gas prices in California and costing drivers in the state an estimated $2.4 billion.   The explosion occurred in the refinery’s fluid catalytic cracking (FCC) unit, where a variety of products, mainly gasoline, are produced. A reaction between hydrocarbons and catalyst takes place in what is known as the “hydrocarbon side” of the FCC unit.

CSB releases final report into 2016 Nitrous Oxide explosion in Florida

April 20, 2017, Pensacola, FL, -- Today, the U.S. Chemical Safety Board (CSB) released its final report into the August 28, 2016, nitrous oxide explosion at the Airgas manufacturing facility in Cantonment, Florida. The blast killed the only Airgas employee working at the facility that day and heavily damaged the plant, halting its manufacturing of nitrous oxide indefinitely. The CSB investigation found that federal regulations require some chemical facilities that manufacture hazardous substances to have process safety management systems in place to protect their workforce and the public.  The CSB discovered, however, that a majority of these specialized rules are not required for nitrous oxide facilities.   Chairperson Vanessa Allen Sutherland said, “Nitrous oxide is a hazardous substance – facilities should have good safety management systems to mitigate the risks that exist.  Safety management systems standards are critical to identify, evaluate, and control process safety hazards. This tragedy in Cantonment should...
