Storage Tank Failures

A pipe that carries sulfuric acid at an oil refinery of Nippon Oil Corp. in Kurashiki was discovered early Monday to be partially broken, resulting in a leakage of the high-concentration liquid, police said.  An employee at the Mizushima oil refinery noticed the leak at about 2:40 a.m. and contacted the local fire department.  It is believed that up to about 1,000 liters of the acid leaked from the five-centimeter-diameter pipe, and there are fears some of the liquid might have spilled into the Seto Inland Sea.  No damage has been reported so far, but the Mizushima Coast Guard Office ordered surveillance vessels to the area to investigate possible damages.  According to the refinery, highly concentrated sulfuric acid used to produce gasoline was sent via the pipe to a factory from a tank about a kilometer from the refinery.

A roll over accident on an I-75 exit ramp had environmental clean up crews busy this morning.  A semi carry sulfuric acid tipped over when it tried to take the exit ramp from State Route 65 to 75.  A small amount of the acid leaked out in the crash.  The State Highway Patrol says that the ramp had to be closed for a short time so that the spill could be cleaned up, but only a small amount is said to have gotten out.

Firefighters worked yesterday morning to contain a spill of sulfuric acid at the Maryland Chemical Co. on Childs Street in South Baltimore.  A Fire Department spokesman said a contract worker was injured when some of the chemical spilled on his hands.  Chief Kevin Cartwright said the worker, whose age and identity were not available, was taken to a hospital.  He said the man had been trying to repair a 4,000-gallon tank when it ruptured about 9:30 a.m.  Most of the spill was contained by a berm set up for that purpose, and Cartwright said there are "no concerns environmentally."  The Fire Department contained the spill by 11 a.m.

Rochester, Minnesota

A tank carrying approximately 175 gallons of sulfuric acid fell off the back of a semi truck on Highway 54 near Grant Avenue in Portage County this morning.  Authorities closed the highway between Stevens Point and Wisconsin Rapids to clean up the spill. The road was still closed at noon. Hazardous materials teams from the Whiting Fire Department and Waupaca county were dispatched to the scene.  The tank was laying in the center median of the highway, and some of the acid pooled in a nearby ditch.  According to Lt. Dan Kontos of the Portage County Sheriff’s Department, the truck was leaving the So-White building on 54 when it turned west and the tank fell.  “There was a vapor cloud when I arrived on the scene,” Kontos said. “I could smell it as soon as I got out of my truck.”  Authorities will set up a series of booms and dikes to keep the chemical from penetrating the ground and reaching the ground water. The next step will be to apply soda ash to neutralize then remove the tank, Kontos said.  “Conditions are good right now because the wind is out,” said Plover Fire Chief Tim Kluck. “At this time we aren’t evacuating the nearby businesses.”  The chemical is used to clean concrete and can be harmful if inhaled, Kluck said.
The state Department of Natural Resources, the Portage County Sheriff’s Department, the Plover Police Department and the Wisconsin State Patrol also responded.

Kiev, 14 June: Sulphur dioxide leaked out at [chemical plant] Stirol Concern in Horlivka, Donetsk Region, at 0600 [0300 gmt] today during the launch after repairs of a facility to manufacture sulphuric acid, the Interfax-Ukraine news agency has learned from the press service of the territorial directorate of the state mining inspectorate in Donetsk Region.  A chemical cloud covered the territory of the state-owned coal mine Shakhta Oleksandr-Zakhid.  The press service said that 17 mine workers had complained they felt bad and had undergone a medical examination.  A total of 15 mine workers have been diagnosed as having poisoning and admitted to hospital.

A derailment of 28 cars on a Union Pacific Corp. (UNP) freight train near Northfield resulted in a leak of sulfuric acid.  Union Pacific spokesman Mark Davis said the derailment occurred near a residential area at about 2 a.m. Monday.  No injuries were reported from the derailment and no evacuations had been ordered as of 6 a.m.  The acid was leaking slowly from only one tanker car.
Twenty-eight of 104 cars on the train left the track.  Emergency crews poured lime on the spilled acid to neutralize it and built an earthen dam to contain it.  An environmental crew also monitored air quality and tested the soil.  Workers planned to pump out the tanker and remove the sulfuric acid in trucks.  The railroad didn't know how much sulfuric acid spilled or exactly how much the tanker contained, but the tanker held up to 14,000 gallons. A second derailed car holding sulfuric acid did not leak.

Follow-up

Car positioning appears to be what caused a 28-car train derailment in Northfield, according to a railroad official.  “The derailment at Northfield on March 31 was determined to have been caused by the way the various train cars were placed or positioned in the train makeup — the way the loaded cars and empty cars were positioned in the train,” said Mark Davis, spokesman for Union Pacific.  The 104-car train headed southbound on its way to North Platte, Neb., derailed north of Greenvale Avenue around 2 a.m. March 31, causing a tanker to leak about 655 gallons of sulfuric acid. There were no injuries nor evacuations, although Davis said he was checking to see if any residents had filed claims with the railroad of suffering poor health as a result of the derailment.  Other than the tanker that was half full with sulfuric acid and another tanker that held peanut oil, the rest of the train’s cars were either empty or carrying stick lumber, Davis said immediately after the derailment.  Davis said Friday in an e-mail that the railroad is running simulations to determine exactly how the makeup of the cars contributed to the wreck. Once they have that information, Davis said, they’ll review it with all employees to ensure proper loading and empty car placement. Federal law also requires that the railroad file a report on its findings to the Federal Railroad Administration.  “An example of how train makeup can contribute to a derailment — if there are too many empty cars in front of heavy-loaded cars as the train is coming to a stop, the heavy cars’ weight will ‘push’ an empty car off the track,” Davis said.  The FRA’s report on the derailment is pending, according to its Web site. At the time of the derailment, FRA spokesman Steven Kulm said it would be months before its investigators would complete their report.

Chinese tanker truck carrying more than 30 metric tons of sulphuric acid has crashed in southwest China, spilling its load into a river and causing "serious pollution," state media said on Wednesday.  The accident occurred on Tuesday, the last day of the Lunar New Year holiday, when the truck ran into the guard rail on a highway linking Anning and Chuxiong in the mountainous province of Yunnan, Xinhua news agency said.  "Some of the sulphuric acid has flown into a roadside river and has caused serious pollution. Many fish were killed," Xinhua said.  No human casualties were reported, but up to 1,000 vehicles were stranded along a section of the highway, it said.  "The government has sent for another truck to load the sulphuric acid still in the truck," Xinhua said. It did not say if the spill had affected any drinking water supplies.

No one was injured when a rail car carrying sulfuric acid came off the tracks at GAC Chemical Corp. and released a small amount of the chemical.  The accident occurred while GAC was taking delivery of four or five carloads of sulfuric acid that came in on the Montreal, Maine & Atlantic Railway. The car derailed due to human error, he said, and came to a rest leaning at a 45-degree angle.   The car's connection to the rest of the train prevented the rail car from tipping completely over.  Once the crane arrived, Dittmeier said the tipped car was hoisted and loaded onto an empty car, so it would remain upright. The process took between two and three hours, he said, to give GAC personnel time to inspect the tracks and rail car for any damages. Dittmeier said there appeared to be no damage to either. Then, the crane was used again to reset the car onto the track.  When the car was being transferred the last time, the repositioning caused it to "burp," according to Dittmeier. This caused about 10 gallons of sulfuric acid to spill onto the top of the railcar, a problem that was easily contained.

A truck spilled 550 gallons of chemicals in Fraser this afternoon, closing Masonic Boulevard, between Groesbeck Highway and Utica Roads.   Local businesses were evacuated and crews conducted a total cleanup of the area.  Fraser Public Safety officers responded to a call around 3:30 p.m. Friday of a vacuum truck containing about 550 gallons of sulfuric and nitric acid developing a leak near one of its valves.  The Clinton Township hazardous materials team arrived on the scene and determined all of the truck's contents had emptied, some of which ran off the road and into a nearby sewer and drain.  No one was injured in the incident.  

Update December 14, 2007 - European Commission's Monitoring and Information Centre (MIC) presents experts' report on oil spill in Kerch Strait.  It concluded that the sunken sulphur did not pose an immediate acute risk to the environment but recommended that the sunken ships with sulphur on board be salvaged so that the sulphur can be appropriately processed.

A road train carrying three trailers of sulphuric acid overturned near Hughenden, in central north Queensland.  The Flinders Highway was closed after the eastbound road train crashed about 30km east of Hughenden.  Police said the road train was passing a truck and sedan travelling in the opposite direction when its third trailer veered into a ditch before swerving across the road and overturning.  None of the sulphuric acid was spilt in the accident and there were no other environmental concerns.  No one was injured in the accident.

A woman crashes into a tank causing an acid spill near Taft.  A hazmat crew was called out after the vehicle had put a four inch gash into the side of a tank carrying sulfuric acid.  The acid was coming out at a slow rate, but did cause a small puddle.  Hazmat determined there was no immediate threat so now it's up to the owner of the land to clean up the mess.  Sulfuric acid is often used in water that farmers use to irrigate.

Louisiana Highway 520 in Claiborne Parish was shut down this morning after a truck hauling sulfuric acid wrecked.  The spill occurred about 1 a.m., half a mile south of the Louisiana 161 intersection in the north part of the parish, State Police said.  There were no homes in the immediate vicinity of the wreck and no one was evacuated, State Police said.

A section of U. S. Highway 59 was shut down due to a hazardous chemical spill.  An 18 wheeler that was carrying about 40,000 pounds of sulfur, crashed into a stalled vehicle on US 59 in Timpson around 7:30 p. m. Monday.  The truck caught on fire and spilled its load all over the highway.  The initial danger was pretty high because of the fumes being emitted from the burning sulfur.  A couple of firemen had to be transported to the hospital due to exposure to sulphur dioxide.
 
The fire took more than four hours to put out.  The fire department initially used water on the fire which enhanced the fire.  A hazardous materials team had to use a special foam to get the flames under control.  The crash site was far enough away from homes that no evacuations were needed.

A fire at the J.R. Simplot Co. fertilizer plant at 200 W. 225 S. caused the evacuation of a 1-mile radius around the plant, as a deposit of sulfur was ignited.  The cause of the fire and extent of its damage were unknown.  East End, West End and Rupert fire departments responded to the fire.  About every 15 minutes, firefighters in two-man teams took turns scaling a ladder to reach the fire through a hole in the roof of one of the plant's buildings. By 7 p.m., the fire was mostly under control.

Nine people were treated and released from hospital following a gas leak at an Inco Ltd. acid plant in Greater Sudbury June 15.  Inco spokesperson Cory McPhee said the plant had a power interuption Thursday at 9:30 am which caused the SO2 (sulphur dioxide) leak into the atmosphere.  "Normally the plants shut down, but in this case one of the fans in the booster house kept going so there was gas sent out that shouldn't have been," said McPhee.  The acid plant is located inside Inco's smelter complex and is used to capture SO2 gas that would normally go up the Super Stack, and turn it into sulphuric acid.  Eight contractors and one Inco employee were sent to hospital after being exposed to the sulphur dioxide. Some were sent home for the day while others came back to work. The gas causes irritation in the throat and lungs.  It (gas) just dissipates  . . . they were able to address the problem but why it happened is still under investigation," said McPhee.  Inco has launched an internal investigation into the matter. McPhee said the company will "file a report of an unusual occurrence" to the Ministry of the Environment, which is standard procedure.

Part of Lake Road near WaferTech in Camas was closed for nearly two hours after a tanker truck spilled about a gallon of sulfuric acid onto the road.  The acid was contained and cleaned up with no runoff and no damage to the road.  Sulfuric acid is a byproduct of WaferTech's manufacturing process, during which silicon wafers are etched with circuitry to make computer chips. The company sells the acid to other manufacturers.  The spill, from a Chemical Transfer Company vehicle, may have been the result of an improperly secured hose, which had been used to drain the acid from WaferTech tanks into the truck.  The vehicle's driver stopped as soon as he realized the chemical had spilled, at about 1:30 p.m.  Southeast First Street was closed between WaferTech's west entrance and Northwest Friberg-Strunk Street until about 3:15 p.m., when cleanup efforts were complete.  The Camas Fire Department worked with WaferTech to neutralize the chemical and clean up the spill.  WaferTech will submit a full report to the state Department of Ecology, which may prompt further review by the agency.

The truck was traveling Northbound on I-476 (Blue Route) and began to exit to get onto I-76 (Schuylkill Expressway) when it overturned around 7:53 a.m.  Smoke was noticed coming from around the vehicle where the load had dumped onto the road and the shoulder of the road.  The smoke was actually corrosive sulpher dioxide gas.  The dry sulphur had apparently mixed with something else causing a massive chemical reaction.  Crews in full hazmat gear arrived.  At the crash scene, air samples showed gas concentrations 30 times the level that can cause respiratory distress.  Fortunately, the plume quickly dissipated.

A sulfuric acid leak at the Dow plant Tuesday afternoon caused only a minor amount of damage and didn’t hurt anyone, officials said.  The leak at the plant in the 3300 block of Fifth Avenue South was small and contained by plant personnel.  A Level 1 alert was issued during the hour-long incident, which started about 1:15 p.m., reports show.  A Texas City Fire Department unit was dispatched to monitor the situation.

An overturned tractor-trailer near Newark early today spilled diesel fuel on the highway and caused lane closures along I-95 well into the afternoon.  Initially police reported that sulfuric acid and hydrochloric acid had spilled from the truck, but later the Department of Natural Resources and Environmental Control determined that it was just fuel from the truck that leaked.  The trailer also contained numerous individual containers of hydrofluoric acid, which was of concern due to the high flammability of the chemical.

A semi-truck drove into a passenger car, which became lodged under the trailer.  The collision then ruptured an acid load in the truck and started a fire.  Three people in the passenger vehicle suffered serious injuries with one listed in critical condition.  The truck driver, as well as three firefighters and four DPS officers, were treated for inhalation problems.  The truck was carrying 1,500 pounds of sulfuric acid, phosphorus acid and sodium hydroxide.

Two 55-gallon drums of sulfuric acid punctured when a truck overturned on Interstate 84 near the southern Idaho town of Burley, closing the highway for about three hours.  Police say the westbound tractor-trailer tipped over on a cloverleaf.  An unspecified amount of sulfuric acid spilled after the accident and the westbound lane was closed.  A state-contracted crew cleaned up the spill after officials with the Idaho Department of Environmental Quality and the Department of Homeland Security determined the leak had stopped.

A sulfuric acid leak at Weyerhaeuser's main Longview plant shot the liquid 45 feet in the air after a valve malfunctioned while a truck was unloading acid.  The leak occurred in a decontamination area and a crew of 15 hazard management workers were nearby to clean the spill up within three hours time.  No one was injured.  The decontamination area had a built-in shower, which made the clean-up easier.

A retired Bastrop Police Department officer is in stable condition in an Arkansas hospital after he was injured when the truck he was driving overturned in southwest Arkansas, spilling sulfuric acid onto the roadside.  Chris Branum, 55, was driving south along U.S. 71 near Ogden, Ark., just after 1 p.m. on Feb. 17 when he apparently lost control of the tanker truck he was driving. A spokesman with Arkansas State Police Troop G headquarters said Branum's skidded almost 150 before it entered the median, where it traveled another 80 feet before it overturned.  According to a story published by the Texarkana Gazette, rescue crews arrived on the scene but were initially kept away from the scene because of the leaking sulfuric acid.  Branum was transported to CHRISTUS St. Michael Health Center in Texarkana and treated for lung and head injuries. On Wednesday, he was reported in stable condition.  The State Police spokesman said no citations were issued following the wreck.

While sulfuric acid was leaking from a ruptured valve on an overturned tanker truck Saturday, the driver was rescued by emergency crews and passing motorists on U.S. Highway 71.  Branum was southbound on U.S. Highway 71 about a mile south of Ogden near the Arkansas Highway Police weigh station when the accident happened.  Authorities say Branum lost control of the rig as he entered a curve in the highway. The truck is owned by Phoenix Transport. Investigators also say gusty west winds may have contributed to Branum losing control of the tanker truck, which was loaded with sulfuric acid.  Firefighters used shovels to dig a trench to direct the flowing acid to a culvert. They also used a smoke ejector fan to blow possible fumes away from the firefighters who were shoveling the dirt.  A backhoe was later used to dig a deeper trench to contain the acid.

Sulphur dioxide was accidentally accidentally released into the air and the gas seeped into Paulsboro High School during first period, causing headaches, feelings of nausea and some instances of vomiting in as many as 15 students and a handful of faculty members.  Valero officials tested the interior of the high school after the release measuring sulfur dioxide at levels between zero and five parts per 1 million parts of air.  The smell of rotten eggs lingered in Paulsboro until the late afternoon, almost disappearing entirely by 4 p.m.

A chemical spill in Tillsonburg caused an evacuation, and sent 7 people to hospital.  At around noon a chemical spill of Sulphur Dioxide happened at Guardian Industries.  Two employees were taken to hospital, were treated and released, five other also went to the hospital were found not to have suffered any effects.  Neighboring businesses and six homes were also evacuated.  Roads in the immediate area were closed for several hours.  The Tillsonburg Emergency Control Group was activated but an emergency was not declared.  The Spills Action Centre was contacted as well as the chemical supplier have dealt with the clean up.

A gas cloud from the DuPont plant located at 12501 Strang Road forced officials to issue a shelter-in-place and shut down a freeway.  Officials said oleum was released from the unit that produces sulfuric acid.  "We had an upset in that process. As a result, we vented a significant amount of sulfuric acid mist," said Ken Martin, DuPont's safety supervisor.  Oleum came out of a 300-foot stack for about 10 minutes.  The unit was shut down and the release was stopped but not until after a large cloud covered the area.  "The cloud itself was a very, very fine sulfuric acid mist. I personally drove through the cloud multiple times in my personal car. The thing I would recommend people do if you thought you were exposed to a significant amount of it or your vehicle, something like that, wash it off this afternoon," Martin said.

Residents south of the plant and along Highway 225 were asked to shelter-in-place until it was lifted at 1 p.m.  Residents in the Pasadena subdivision of El Jardin were under a shelter-in-place until 1:30 p.m.  La Porte Independent School District schools were included in the shelter-in-place.  Highway 225 was shut down in both directions between at Highway 146 at Sens Road.

No one was injured.

Nearly 100 gallons of sulfuric acid spilled a parking lot at French Paper Co. in Niles.  There were no injuries and no equipment was damaged.  A container tipped while being transported by a  forklift.  Mill staff contained, neutralized and cleaned up the spill.  Nobody was injured and at no time was anyone in danger.  Sulfuric acid is used in paper making for pH control.  French Paper employees and emergency personnel used a powder to soak up the sulfuric acid and it was then placed in a dumpster and French Paper is waiting approval from state agencies to dispose of it.

A spokesperson for the Polk County, Tennessee Sheriff's Office says that they have been forced to shutdown Highway 64 due to a sulfuric acid spill. A tanker truck has overturned on the Highway near Parksville Lake and is apparently leaking acid. Emergency and Hazardous Materials Teams are on the scene, or enroute to try and contain the leak. There are no homes or businesses in the immediate area so no evacuations are underway. However, again, Hwy. 64 is closed in both directions near Parksville Lake.

A train spilled around 35 tons of sulphuric acid destined for the copper industry after being derailed by broken tracks.  The train was carrying some 72 tons of the acid which was headed for the country's largest copper mine, the Indian-owned Konkola Copper Mines (KCM).  The accident occurred 50 miles north of the tourist capital Livingstone.  Railway officials told the local press that unless the spill could be quickly neutralized with lime, there was a good chance that rain would wash it into a nearby canal, posing a danger to local people, livestock and wildlife.  This was the second major accident in as many weeks for KCM, which last week allowed untreated effluent from a plant in the town of Chingola to spill into a nearby river.

A truck driver was filling his truck with the dangerous liquid when something apparently went wrong. He’s been taken to a local hospital. The extent of his injuries remains unclear.  Between 500 and 1000 liters of the acid reportedly leaked, but apparently did not get into the water, where it would have combined to produce a poisonous gas.

Teams from around the region yesterday were trying to recapture about 1,500 gallons of sulfuric acid that escaped from a tank near the Granby town line Monday night and forced the cancellation of school in South Hadley and the evacuation of 88 households in Granby and South Hadley.  A police officer was treated for exposure to sulfuric acid fumes.  In Granby, 68 households were evacuated as a precaution following the spill about 8 p.m. on Monday at Presstek Inc., 755 New Ludlow Road.  The liquid leaked into a cement holding pit.  On Tuesday, the evacuation was extended to include 20 homes on East Street in South Hadley because the spill formed a gas inside the building.
