EQUIPMENT FAILURE LEADS TO TUBE FURNACE OVERHEATING AND SAMPLE TUBE OVERPRESSURIZATION
Tags: us_IL, laboratory, release, response, unknown_chemical
Discussion: In the evening of December 21, 2015, a post doc in the Materials Science Division placed a sealed fused silica tube containing a few grams of a rubidium bismuth bromide complex salt into a tube furnace. The furnace was in a ventilated enclosure (perforated bottom for air flow) with the polycarbonate doors closed. The procedure required the tube furnace to ramp up to 700 degrees Fahrenheit, hold at temperature for five hours, then ramp back down to room temperature. At approximately 11:33 pm, the smoke detector triggered the fire alarm in the building. The building was evacuated, and the Argonne fire department responded. The digital display on the furnace indicated a temperature of 350 degrees Fahrenheit, however the inside of the furnace was glowing brightly, which indicated that the temperature inside the furnace was much higher. Insulation debris and sample powder were found inside and under the enclosure, indicating that the sealed tube had burst. The furnace!
and its controller were de-energized, and the area was roped off for further investigation.
Analysis: An investigation concluded that the experiment was correctly carried out and that the likely cause of the incident was equipment failure of the furnace controller or its associated temperature sensor. This failure allowed the furnace to heat in an uncontrolled fashion to reach a temperature where the sample decomposed into volatile components that exceeded the maximum pressure for the sealed tube and caused it to rupture.

TULSA FIRE DEPARTMENT: SICK DELTA AIRLINE PASSENGERS HAD ELEVATE
Tags: us_OK, transportation, release, response, carbon_monoxide
TULSA, Oklahoma - Tulsa firefighters said the Delta airline passengers who became ill on a flight that was diverted to Tulsa were suffering from elevated carbon monoxide levels in the blood.
Delta flight 1817 left Atlanta en route for Denver Saturday but landed instead at Tulsa International around 3:30 p.m. due to complaints of illness.
The district chief that responded to the incident said they initially had reports that 12 to 15 passengers complained of nausea, headache and dizziness, TFD told News On 6. EMSA and Hazmat crews responded and pulled everyone out of the plane.

NASHUA, N.H. (CBS) ‰?? New Hampshire police and bomb squad spent hours at a Broad Street home in Nashua Sunday evening.
Police said family members were cleaning out a deceased member‰??s home when they found the device.
The department‰??s hazardous device unit dug a hole in the backyard and burned off the device.
Broad Street from Coliseum Avenue to Greenlay Street was closed to traffic for at least 3 hours.

U.S. CHEMICAL SAFETY BOARD INVESTIGATES MISSISSIPPI NATURAL GAS PLANT ACCIDENT
Tags: us_MS, transportation, follow-up, environmental, natural_gas
The U.S. Chemical Safety Board launched its first major investigation in a year with a probe of a June 27 fire and explosion at a natural gas processing facility in Pascagoula, Miss.
The past year was difficult for CSB, involving a congressional investigation and the termination of the board‰??s former head. Last October, new CSB Chair Vanessa Allen Sutherland announced that the board would halt new investigations and reboot its organization and structure. The freeze on probes continued until the Mississippi incident.
No one was injured in the accident, but the plant has remained shuttered since it happened, says a spokesperson for Enterprise Products Partners, which owns the facility. The accident occurred in one of three process lines, or trains, as the facility handles incoming hydrocarbons and separates the material into natural gas liquids and residual gas.
The cause of this late-night accident is unclear at this time, say CSB and company officials.
A former BP facility, the Enterprise Products Partners plant processes approximately 42.5 million cubic meters per day of natural gas from offshore operations in the Gulf of Mexico. It is one of 25 similar U.S. processing plants the company operates.
Once separated, the natural gas liquids are transported from the Pascagoula plant to a facility in Louisiana through a pipeline for further refining.

PCB FIND DELAYS SCHOOL DEMOLITION BY SEVERAL WEEKS
Tags: us_CT, education, discovery, environmental, pcbs
PLAINVILLE ‰?? Despite the recent discovery of additional hazardous materials in Old Linden Street School, the project is expected to be completed by the end of the month, says Town Manager Robert E. Lee.
Within the last two weeks, demolition crews with Manafort Brothers discovered a black paint on interior masonry, school perimeter walls and behind wooden walls in the east wing of the building.
Testing confirmed that this paint contained polychlorinated biphenyl ‰?? PCB ‰?? which is now considered a hazardous, carcinogenic material. 800 to 1,000 tons of the material must be removed from the interior masonry and perimeter walls and 600 to 700 tons must be removed from the east wing before the project can continue.
Asbestos and other hazardous materials had been removed earlier in April, prior to the demolition beginning.
However, as Jeff Duigou of Eagle Environmental Inc. told the Capital Projects Building Committee during their June 27 meeting, it is common to find additional hazardous materials within old buildings once walls begin to be removed.

PRESENCE OF CHEMICAL IN LAPLACE‰??S AIR INCREASES CANCER RISK, ENVIRONMENTAL OFFICIALS SAY
Tags: us_LA, industrial, discovery, environmental, toxics
LAPLACE ‰?? The approximately 43,000 people living in St. John the Baptist Parish share an unenviable distinction of having the highest potential risk of cancer in the state due to industrial releases into the air.
It‰??s a relatively new distinction.
The U.S. Environmental Protection Agency in December published a National Air Toxics Assessment map created to give state and federal agencies an idea of where more investigation is necessary.
‰??This is an issue we find very important,‰?? said Ron Curry, administrator of the EPA‰??s Region 6,which includes Louisiana.
About 150 residents gathered last week to hear what state and federal officials had found and what their agencies, as well as the company that releases the chemical of most concern, chloroprene, are doing about the newly discovered issue.

FED SCIENTISTS FINISH STUDY OF WEST VIRGINIA CHEMICAL SPILL
Tags: us_WV, industrial, follow-up, environmental, cleaners
CHARLESTON, W.VA.
Federal government scientists have released a final update of their study of the January 2014 chemical spill that temporarily fouled the drinking water supplies of 300,000 Charleston-area residents, reporting no significant new findings.
The Charleston Gazette-Mail ( https://urldefense.proofpoint.com/v2/url?u=http-3A__bit.ly_29uLXOS&d=DQIFaQ&c=lb62iw4YL4RFalcE2hQUQealT9-RXrryqt9KZX2qu2s&r=meWM1Buqv4IQ27AlK1OJRjcQl09S1Zta6YXKalY_Io0&m=Z7TQcADfxUACSD2xEbJIAOSc3IBc47thSB_eUkYk-qc&s=Gf9D-5WR9TjP73IIGPpC_gPg_QQQbioOT6O7I_upTTI&e= ">https://urldefense.proofpoint.com/v2/url?u=http-3A__bit.ly_29uLXOS&d=DQIFaQ&c=lb62iw4YL4RFalcE2hQUQealT9-RXrryqt9KZX2qu2s&r=meWM1Buqv4IQ27AlK1OJRjcQl09S1Zta6YXKalY_Io0&m=Z7TQcADfxUACSD2xEbJIAOSc3IBc47thSB_eUkYk-qc&s=Gf9D-5WR9TjP73IIGPpC_gPg_QQQbioOT6O7I_upTTI&e= ) cited the report Friday as finding "most of the spilled chemicals had no effects in the studies that were performed" after the spill of coal-cleaning agent Crude MCHM at a Freedom Industries site near the Elk River that year.
The work was conducted by the National Toxicology Program at the U.S. Department of Health and Human Services. The newspaper said scientists found any potential for negative health effects would only occur at significantly higher doses than residents would have had in their water under a health advisory set up after the spill.
One concern not addressed in the report is how dangerous inhalation of the chemical might be. Residents may have been exposed to airborne MCHM when they followed state-promoted guidelines for running hot and cold water to flush the chemical out of their pipes. Federal officials originally planned to study that and come up with a limit for how much MCHM is safe in the air, but they quickly abandoned the idea and no air sampling was done.
John Bucher, associate director of the NTP, said in a phone interview, "We really had no clue about what kinds of levels of exposures were happening during the flushing."
Bucher also said it's not clear why the federal study found skin irritation from the chemical only at very high exposure levels, while residents reported such effects as a common symptom when they sought medical help following the spill.

SIX YEARS AFTER MAYAPURI, DU LABS STILL NOT SAFE
Tags: India, laboratory, follow-up, environmental, radiation, waste
NEW DELHI:Six years after the Mayapuri incident, in which Delhi University (DU) Chemistry department discarded waste containing radioactive Cobalt 60 that injured several scrap dealers in 2010, over 300 laboratories dealing with hazardous chemicals in 70 odd DU colleges are still compromising on safety norms.
With no proper ventilation in most of these laboratories and without any set guidelines for discarding of radioactive waste, the DU labs are sitting on a tinder box, waiting for a massive destruction.
‰??Most labs are not following the Atomic Energy Regulatory Board (AERB) guidelines. Signs are missing; height of roof is not as per norms, nor is there any proper ventilation. Student strength is increasing for the science courses, but manpower is still the same and so is the infrastructure. Hence, it is resulting in overcrowding of labs,‰?? a staff working in the science department of the university said.
When asked about the safety norms followed by the labs, Dean of Science department, DU, MK Pandit said, ‰??We have a special lab safety committee and their representatives are in each department. They do safety inspections on a regular basis. We also follow all the fire safety guidelines that are prescribed by the National Assessment and Accreditation Council (NAAC).‰??

Tags: us_UT, industrial, fire, response, unknown_chemical
(KUTV) Salt Lake Fire Crews are responding to a large 5-alarm blaze near 4201 W. 700 South.
According to the Salt Lake City Fire Department, callers are reporting that pallets and buildings are on fire Hazmats may be involved and there have been reports of explosions on scene.
The fire department tweeted around 3:30 p.m. that a worker at Rio's Auto Recycling was cutting pallets, producing small sparks. He thought he extinguished all small fires from the sparks and went to lunch. When he returned, he found an active fire that he could not extinguish.
SLC Fire tweeted out saying they had approximately 100 firefighters from multiple agencies on scene, one of those firefighters is reported to have received minor injuries, no other injuries at this time.

Tags: us_CA, industrial, release, response, ag_chems, pesticides
Smith Avenue is still closed at McCombs and Highway 46 on both ends due to a hazmat situation in the area.
Environmental Health told 17 News that a farm worker found two containers that were dumped in an orchard. One container was empty and the other container was a quarter full of some type of pesticide. The pesticide that was in that container was considered toxic, but no one came in contact with it.
Environmental Health also says the container hit the ground and cracked and they approximate 5 to 10 gallons of the pesticide went into the soil. That is currently being cleaned up. No one was injured and we have no word on when the road will be back open.

CHEMICAL SPILL TEMPORARILY CLOSES TRANSFER STATION, NOW BACK OPEN
Tags: us_MA, laboratory, release, response, sodium_hydroxide, waste
A chemical spill on Thursday, July 7 temporarily closed Winchester's transfer station on McKay Avenue, but it was back up and running as of Friday morning, according to Fire Chief John Nash.
Nash told the Star a rupture occurred in a 55-gallon drum, resulting in the leakage of sodium hydroxide, known as lye. The incident was reported to the fire department at 4:37 p.m. and firefighters were on scene at the transfer station until 6:45 p.m., said Nash.
"The transfer station has been rendered safe, and people can continue to bring their trash there this weekend" he said, adding that a private vender conducted the cleanup using an absorbent packaging material.
Nash said the drum had been brought to the transfer station because of the high school renovation project, and could possibly be left over materials from the high school lab, although he couldn't be sure.

DUPONT TO PAY $500,000 TO OHIO MAN IN CHEMICAL ILLNESS LAWSUIT
Tags: us_OH, public, discovery, environmental, unknown_chemical
COLUMBUS, Ohio (AP) ‰?? A federal jury says DuPont should pay $500,000 in punitive damages to an Ohio man in a chemical illness lawsuit.
The jury decided the amount Friday, the Columbus Dispatch reports.
Earlier this week, the same jury said DuPont Co. acted with malice by dumping chemical-tainted water from its West Virginia plant into the Ohio River. Jurors awarded $5.1 million in compensatory damages to the Washington County man, who developed cancer.
A DuPont spokesman said Friday the verdict will be appealed, and jurors were misled about the risk of the chemical exposure.
The man, David Freeman, says he got testicular cancer because of C8 used to make Teflon.

BUILDING EVACUATED AS A PRECAUTION AFTER CHEMICAL RELEASE IN BOSTON ‰?? BOSTON NEWS, WEATHER, SPORTS
Tags: us_MA, public, release, injury, bromine, water_treatment
Multiple emergency crews were on the scene of a chemical release on High Street in Boston.
The 32-story high-rise building at 99 High Street was evacuated as a precaution as Haz-Mat teams worked with property managers.
The initial belief was a chemical spill on the 18th floor of the building. Upon further review, it was not a spill but a release of bromine, which is used in water treatment.
The release happened in the mechanical room, and a ventilation system caused the odor to be detected on several other floors, according to the Boston Fire Department.
The fire department said the building ventilation system was shut down, and a separate ventilation system was used to clear the rooms affected.
The chemicals Glutaraldehyde and Sodium Hydroxide were mixed with the bromine, causing a reaction during the filling process.
Boston EMS says three people were transported to area hospitals ‰?? one to Tufts and two to MGH. Those transported had non-life-threatening injuries.

FIRE LAB SOURCE OF CHEMICALS FOUND IN DRINKING WATER, NRC CONFIRMS
Tags: Canada, laboratory, follow-up, environmental, other_chemical
Government officials have confirmed the National Fire Laboratory is the source of chemicals that contaminated the drinking water in Mississippi Mills, Ont.
Homeowners living near the facility found out in December 2015 that perfluoroalkylated substances, or PFAS, were discovered in their tap water. It's the same chemical often found in firefighting foams.
In an emailed statement to CBC News, the National Research Council confirmed Thursday that "ongoing environmental assessments have indicated that PFAS found in the nearby residential wells originated from the National Fire Laboratory site.
"Since identifying PFAS at the National Research Council's National Fire Laboratory, our focus has been on carrying out an effective and thorough environmental assessment and on the continued safeguarding of the health and safety of residents and employees," the statement said.
"They admitted they were essentially ground zero of the problem," said the municipality's mayor, Shaun McLaughlin. "This is the first time they've actually owned that piece of the mystery."
Back in 2013, the NRC knew contaminants were found in the groundwater from drill sites close to the facility.
Two years later, the government department started delivering bottled water to some neighbouring homes and paying for charcoal water filtration systems.

ASSESSING POTENTIAL RISKS FROM EXPOSURE TO CHEMICAL MIXTURES ‰?? JRC REVIEW OF CASE STUDIES ‰?? EURL ECVAM
Tags: Belgium, public, discovery, environmental
A review of case studies assessing the risk from exposure to chemical mixtures shows a potential concern for several groups of chemicals for highly exposed or particularly vulnerable population groups.
Humans and wildlife can be exposed to an almost infinite number of different combinations of chemicals in mixtures via food, consumer products and the environment, which raises concerns for possible impacts on public and environmental health. A review of recent literature by the JRC's EU Reference Laboratory for Alternatives to Animal Testing (EURL ECVAM) summarises the outcome of case studies covering several chemical classes. Parameters that could lead to an over- or underestimation of potential risks were identified. Case study results need to be interpreted with caution, considering the underlying assumptions, model parameters and related uncertainties. However, there is clear evidence that chemicals need to be further addressed not only in single substance risk assessments but also in mixture assessments that cover multiple chemical classes and legislative sectors.
Furthermore, several issues hampering mixture risk assessments are identified. In order to perform a mixture risk assessment, the composition of the mixture in terms of chemical components and their concentrations need to be known, and information on their uptake and toxicity are required. Screening level assessments based on conservative assumptions are generally possible. However, refining such assessments to more realistic exposure scenarios is often not feasible due to data gaps. In particular, relevant exposure and toxicity data as well as information on modes of action are often lacking.
Future case studies on mixture risk assessment could fill the knowledge gaps identified in this review. Such case studies could help by addressing differences between population groups, investigating different and emerging groups of substances, considering the relevance of interactions (i.e. synergisms), examining different approaches for the grouping of chemicals, and especially by investigating mixtures of potential concern that cross regulatory sectors.

HYDROCHLORIC ACID INVOLVED IN CHEMICAL SPILL
Tags: Canada, transportation, release, response, hydrochloric_acid
We now have a few more details regarding the chemical spill that happened on Highway 1 yesterday afternoon.
Sargent and Detachment Co-ordinator with the Swift Current Rural RCMP Scott Hunter, explains what it was that spilled on to the road.
"There was a small barrel of hydrochloric acid we believe fell out the back of a truck in the eastbound lane of Highway 1. The chemical had to be cleaned up so the Fire Department attended with us."
Traffic was affected due to the spill as Hunter explains.
"Traffic was rerouted around the scene while they cleaned it up. There was no environmental damage and no injuries reported. Traffic was re-routed for approximately two hours."

A PASCAGOULA NATURAL GAS PROCESSING PLANT ROCKED BY EXPLOSIONS ON JUNE 27 REMAINS OFFLINE
Tags: us_MS, industrial, follow-up, response, natural_gas
JACKSON, Mississippi ‰?? A Mississippi natural gas processing plant rocked by explosions on June 27 remains offline.
Rick Rainey, a spokesman for Houston-based Enterprise Products Partners LP, said Thursday that the operator can't predict when the Pascagoula plant will restart.
The plant extracts liquids from natural gas, sending the gas to users and the liquids to plants making propane and butane. Because the plant isn't running, some oil and gas platforms in the Gulf of Mexico are limiting production. Some natural gas is being diverted from the Destin Pipeline, which feeds the Pascagoula plant, to another connected pipeline, the Viosca Knoll Gathering System, according to online notices. Gas is then piped ashore for processing in Louisiana. But capacity is limited to 330 million cubic feet per day, below the 400 million cubic feet per day that Enterprise said the plant was handling before the explosions.
Limits on gas transport also can limit oil production from the 12 oil and gas platforms on the Destin Pipeline. Oil and natural gas come up together through wells, and if owners have nowhere to send the natural gas, they can't produce as much oil.
Flames shot from the plant for hours after the explosions last month.
