No charges for teen after explosion at Fla. school

A Florida teenager who was accused of igniting a chemical explosion on school grounds — and who became the subject of a social media campaign on her behalf — will not face criminal charges.

Kiera Wilmot was arrested April 22 and faced two possible felony charges after school administrators reported she combined toilet bowl cleaner and aluminum foil in a bottle, and the resulting gas blew the cap off the plastic bottle.

The Polk County state attorney said Wednesday that the case has been dismissed, but the 16-year-old must complete a diversion program.

Details about the program aren't public record because Kiera is a juvenile.

The teen's arrest launched an international outcry on social media by people who thought the arrest was unfair. Nearly 200,000 people signed an online petition protesting her arrest.

Correction: Mexico-Gas Explosion story

In a story May 7 about a gas tanker truck explosion in Mexico City, The Associated Press reported erroneously that the truck was carrying natural gas. Its cargo was liquid petroleum gas.

A corrected version of the story is below:

22 dead in gas tanker explosion near Mexico City

22 dead, dozens injured when gas tanker crashes on highway and explodes in Mexico City suburb

By ADRIANA GOMEZ LICON and JOSE OSORIO

Associated Press

MEXICO CITY (AP) — A tanker truck hauling liquid petroleum gas lost control, hit a center divider and exploded on a highway lined by homes in the Mexico City suburb of Ecatepec early Tuesday, killing at least 22 people and injuring nearly three dozen, authorities said.

Officials at the Citizen Safety Department of Mexico State, which surrounds the capital, did not rule out the possibility the death toll could rise. At least a dozen people remained hospitalized late Tuesday, several of them in critical condition.

Gov. Eruviel Avila said late Tuesday that 22 people were known dead in a letter to Pope Francis, with whom he was supposed to meet at the Vatican on Wednesday. Avila said he was returning to Mexico instead.

The state safety department's spokesman, Cesar Diaz, said emergency workers would continue searching through the night in the charred remains of vehicles and homes built near the highway on the northern edge of the metropolis.

Residents pitched in to rescue people from the wreckage of the 5:30 a.m. explosion, crushed and burned cars and shattered homes. Television footage showed plumes of flame shooting out of homes in the pre-dawn darkness.

A huge piece of the truck's gas tank was blown 50 yards by the blast, landing atop the wall of a house and cars parked outside. A number of pigs, goats and other farm animals that were kept on patios were killed.

"It was thunderous sound. I thought we were all going to die," said Rita Enriquez, 42, a housewife who lives nearby. "When we ran out, we saw a car on fire and flames everywhere. Smoke was pouring all over the freeway."

Mario Lopez, 43, a mechanic, lives in the house hit by the tank and managed to escape with his three sons after being awakened by the blast.

"All the windows broke to the inside. We got down and left crawling," said Lopez, who lost a brother, a sister, three nephews and a sister-in-law who all lived in separate units of the three-story home. He said 12 people in all died in the house. "Everything was in flames," he said.

Enriquez said five of her relatives were gravely injured in their concrete slab home along the road, though she had no other details as she waited for word outside Magdalena Las Salinas Hospital in Mexico City.

Her 15-year-old niece, Wendy Garrido, who was pregnant, was forced to give birth after the explosion, she said. They survived but both were in intensive care, Health Secretary Cesar Gomez said.

The pre-dawn disaster exposed two recurrent public safety issues in Mexico: extremely heavy trucks that are frequently involved in serious accidents, and the construction of improvised homes just feet away from major highways.

Some of the cinderblock homes hit by the huge explosion were just steps from the busy, eight-lane highway. Other homes were mere shacks, built of sheet tin.

Lopez said the highway recently had been widened, bringing traffic perilously closer to their dwellings.

"They never thought a car could hit them or an explosion of this magnitude," said Maribel Juarez, the cousin of another family killed in the explosion. "Now we have to bury their coffins and our family members are never going to return."

The driver, Juan Olivares, 36, was heading south from the city of Pachuca to Mexico City in a tractor that was hauling two gas tanks on tandem trailers, said Jose Luis Cervantes, an assistant state prosecutor. He said the vehicle belonged to the Termogas company.

Cervantes said the tractor hit a center divider and broke apart, with one tank flying into a house and exploding, killing 15 people, and another part of a tank hitting a separate house, killing four.

State security officials counted 33 people with various injuries.

The driver, who was under detention while being treated at a hospital, could face manslaughter and property damage charges, the prosecutor said.

"We just pulled burned people, and put out the fire in the houses, but we don't really know what happened," said Rogelio Martinez, a resident.

Emergency personnel at the scene pulled dead from their homes, some apparently burned in their beds. An Associated Press journalist saw rescue workers carry three bodies, covered with white sheets, from one home.

One small passenger van had been totally gutted by flames and tossed against the wall of one of the many improvised houses next to the highway.

Hundreds of police, ambulance drivers, paramedics, soldiers and firefighters gathered at the scene.

Pablo Bedolla, the mayor of Ecatepec, a mainly working-class area, said 20 homes and one school had been damaged by the blast. The explosion happened before class hours, so there were no apparent injuries in the school.

"People are very shaken, above all because of the injuries and the large number of dead," Bedolla said. "I've spoken with the families of the victims, and they are just sobbing."

The explosion closed the highway between Mexico City and Pachuca for hours.

Speaking in Mexico City, President Enrique Pena Nieto suggested something would have to be done to separate major highways from poor neighborhoods.

"I have instructed the Transportation Department ... to review the safety conditions on this federal highway in places where structures have been built on the right of way, so that in the near future, work can be carried out to make it safer," Pena Nieto said.

Often in Mexico, squatters settle on rights of way, the strips of land on either side of a highway or railway line that are intended to be buffer zones. The gradual spread of shacks creates neighborhoods that are inherently unsafe.

This highway, however, was recently expanded, so it was unclear whether the land occupied by homes was legally settled.

The Mexican government also appears to have realized it has a big problem with over-weight trucks. Such trucks, often unsafely operated, have been involved in a number of spectacular, deadly accidents in recent years.

On Tuesday, the Transportation Department announced it had set up a panel of experts to study the issue of maximum allowable weights, "to set out opinions on eventually changing the weight standards, or drawing up a new set of rules."

One year ago, the Mexican government announced measures to tighten inspections and lower maximum allowed weights for some freight trucks after protests over a string of deadly accidents involving double-trailer trucks like the one involved in Tuesday' disaster.

Mexico has allowed trucks to travel highways with loads of up to 80 metric tons and lengths exceeding 100 feet, compared to a U.S. limit of 80,000 pounds, or 40 tons, on interstate highways.

In April 2012, a double-trailer truck on a two-lane road in the Gulf coast state of Veracruz lost its rear trailer, which slammed into a bus carrying farm workers, killing 43 people.

Nuclear board warns of Washington tank explosion risk

  • Hanfordleakrisks.jpg

Underground tanks that hold a stew of toxic, radioactive waste at the nation's most contaminated nuclear site pose a possible risk of explosion, a nuclear safety board said in advance of confirmation hearings for the next leader of the Energy Department.

State and federal officials have long known that hydrogen gas could build up inside the tanks at the Hanford Nuclear Reservation, leading to an explosion that would release radioactive material. The Defense Nuclear Facilities Safety Board recommended additional monitoring and ventilation of the tanks last fall, and federal officials were working to develop a plan to implement the recommendation.

The board expressed those concerns again Monday to U.S. Sen. Ron Wyden, D-Ore., who is chairman of the Senate Energy and Natural Resources Committee and had sought the board's perspective about cleanup at Hanford.

The federal government created Hanford in the 1940s as part of the secret Manhattan Project to build the atomic bomb. It spends billions of dollars to clean up the 586-square-mile site neighboring the Columbia River, the southern border between Washington and Oregon and the Pacific Northwest's largest waterway.

Federal officials have said six underground tanks at the site are leaking into the soil, threatening the groundwater, and technical problems have delayed construction of a plant to treat the waste for long-term safe disposal.

Those issues are likely to come up during confirmation hearings next week for Energy Secretary-nominee Ernest J. Moniz. The fears of explosion and contamination could give Washington and Oregon officials more clout as they push for cleanup of the World War II-era site.

Central to the cleanup is the removal of 56 million gallons of highly radioactive, toxic waste left from plutonium production from underground tanks. Many of the site's single-shell tanks, which have just one wall, have leaked in the past, and state and federal officials announced in February that six such tanks are leaking anew.

"The next Secretary of Energy - Dr. Moniz - needs to understand that a major part of his job is going to be to get the Hanford cleanup back on track, and I plan to stress that at his confirmation hearing next week," Wyden said in a statement Tuesday.

The nuclear safety board warned about the risk of explosion to Wyden, who wanted comment on the safety and operation of Hanford's tanks, technical issues that have been raised about the design of a plant to treat the waste in those tanks, and Hanford's overall safety culture.

In addition to the leaks, the board noted concerns about the potential for hydrogen gas buildup within a tank, in particular those with a double wall, which contain deadly waste that was previously pumped out of the leaking single-shell tanks.

"All the double-shell tanks contain waste that continuously generates some flammable gas," the board said. "This gas will eventually reach flammable conditions if adequate ventilation is not provided."

All of the tanks are actively ventilated, which means they have blowers and fans to prevent a buildup of hydrogen gas, and those systems are monitored to ensure they are operating as intended, Energy Department spokeswoman Carrie Meyer said.

For even greater safety, she said, the agency implemented an improved monitoring system in February.

"DOE is absolutely committed to ensuring the safety of Hanford's underground tanks," Meyer said.

The board also noted technical challenges with the waste treatment plant, which is being built to encase the waste in glasslike logs for long-term disposal. Those challenges must be resolved before parts of the plant can be completed, the board said.

The federal government spends about $2 billion annually on Hanford cleanup -- roughly one-third of its entire budget for nuclear cleanup nationally. About $690 million of that goes toward design and construction of the plant. Design of the plant, last estimated at more than $12.3 billion, is 85 percent complete, while construction is more than 50 percent complete.

The problems identified by the board show that the plant schedule will be delayed further and the cost will keep rising, Wyden said, adding: "There is a real question as to whether the plant, as currently designed, will work at all."

9 dead, dozens hurt in Mexico fireworks explosion

Authorities in central Mexico say at least nine people were killed and dozens injured when a pickup truck carrying fireworks caught fire and blew up during a religious celebration at a small village.

Tlaxcala state Civil Protection director Jose Morales says the explosion in Jesus Tepactepec happened as people were in a procession and a firework malfunctioned and landed on the truck carrying the rest of the fireworks.

Morales says nine people are known dead and adds that there are also injuries but he doesn't know how many. Authorities in neighboring Puebla state say 45 injured people have been taken to hospitals in their state.

3 critically injured in Illinois plant explosion, hospital reports

At least 10 people were injured, including three critically, in an explosion Thursday at a U.S. steel castings plant, officials said.

The blast happened in the morning in the cleaning-and-finishing department at the American Steel Foundries plant in Illinois. Roughly 800 people work at the plant, which produces railcar undercarriages and related components, said Mike Right, the United Steelworkers union's health, safety and environment chief.

Seven workers treated for smoke inhalation at Gateway Regional Medical Center were released later Thursday, while three others were in critical condition and flown by helicopter to other hospitals, Gateway spokeswoman Kate Allaria said.

Two of them were listed in critical condition later Thursday at Mercy Hospital in Creve Coeur, spokeswoman Bethany Pope said. It wasn't immediately clear where the other worker was being treated.

Federal workplace safety officials are investigating the cause of the blast. Calls and emails to the business went unanswered Thursday.

Robert Lott, a worker at the plant and president of the United Steelworkers Local 1063, told the Belleville News-Democrat that at least two of those injured may have suffered broken legs and internal injuries. He said he believed the blast was caused by a gas leak.

"I could see flames, initially, and then the visibility went down to zero from the dust that fell from the rafters," said Lott.

Right said the union was sending an investigator to the Granite City plant "to make sure we learn the lessons and really understand what happened."

"At this point everything is pretty sketchy, and we really don't like to comment on causes until we have them tied down," he said.
