Without Safety, Chemistry Labs Turn into Danger Zones -
(Salt Lake Tribune - Sunday, July 7, 2002) BY TAMMY WEBBER THE ASSOCIATED PRESS GENOA, Ill. -- In a blinding flash, the routine high school chemistry experiment turned to chaos. An alcohol-fueled fireball shot into the classroom, searing the skin of three junior honor students in the front row. They took the brunt of the blast on their faces, necks, arms, hands and legs. The teacher pulled burning jeans off one of the girls; scorched skin fell from the boy's face. The rest of the class scrambled for the door, leaving burned backpacks and books behind. The fire at Genoa-Kingston High School in October may have been a horrible accident, but it was not isolated. Across the country, at least 150 students have been seriously injured in school laboratory accidents in the past four years. But the number is almost certainly much higher, according to interviews with researchers, school officials and insurance companies. And the stage is set for a significant increase, they said. As schools try to meet tough new science education standards set by the National Academy of Sciences in 1996, students are spending more time in laboratories. Some are crowded. Some have teachers with no safety training. Some are in 19th-century buildings ill-equipped for 21st-century science. "Before, most kids were reading out of textbooks, but the new federal science standards absolutely, strongly advocate hands-on, inquiry-based science," said Kenneth Roy, who chairs an advisory board on science safety for the National Science Teachers Association. "What this means is, you have to have safety concerns as job one, but some schools don't." Little Regulation: And while teachers are protected in the workplace by state laws, students are not covered by those laws. There is little regulation of school labs, and no government or private agency collects official data on accidents that happen there. As a result, the exact number of accidents is unknown. Almost all of the accidents and injuries could have been prevented with simple safety measures, experts said. But many teachers are unaware of the dangers, and there is no formal system to share information on accidents so teachers can learn from others' mistakes. Yet they occur often enough to be considered a serious problem, according to safety experts and insurers who have paid millions of dollars to settle claims. "There have been some terrible accidents and injuries that are just absolutely gross," said John Wilson, executive director of the Schools Excess Liability Fund in California, which recently paid more than $1 million in one case involving a chemistry accident and more than $3 million in another. A settlement is pending in a third accident, involving a Riverside, Calif., girl who was burned over 20 percent of her body. She is getting treatment to reduce scarring and improve the use of her badly burned right arm. There is evidence that the number of accidents has risen since schools began adopting the new teaching standards. In Iowa, there were 674 accidents in the three school years from fall 1990 through the spring 1993, but more than 1,000 in the following three years, said Jack Gerlovich, who teaches science safety at Drake University. The increase came after Iowa schools began adopting an early version of the new standards, he said. The number of lawsuits soared, too, from 96 to 245. Gerlovich said he suspects the same thing is happening in other states. If accurate statistics were gathered, Gerlovich said, "I think the actual numbers would be much, much higher, but it's the kind of problem nobody wants to face." Engulfed in Flames: When the swoosh of fire hit Autum Burton, she was returning to her seat in her chemistry class after taking a closer look at the colors of the flames in the six petri dishes on the teacher's table. In an instant, she was engulfed in flames. "I could feel it eating at me and I could smell my skin burning," she recalled recently. "I was on the floor trying to get this off with my hands." By the time someone finally managed to wrap her in a blanket and put out the fire, she was burned over almost half her body: face, neck, chest, arms and legs. Burton, 19, now attends Columbia College in Chicago. Despite eight skin graft operations and three laser treatments to diminish scarring on her face, she will be disfigured for the rest of her life. The accident happened two years ago at Lakeview High School in Battle Creek, Mich. Just two months earlier, a 16-year-old girl was severely burned in a similar accident that had happened about 40 miles away, at Waverly High School near Lansing. In both cases, the experiments involved methyl alcohol. A volatile chemical that ignites easily, methyl alcohol often is involved in the most catastrophic accidents. In recent years, it also has caused flash fires at schools in Santa Clarita and Riverside, Calif.; Genoa, Ill.; Midland, Texas; New Berlin, Wis.; and Washington, D.C. It has also caused explosions in which students were injured by flying glass. If the teacher does not use an exhaust system, leaves the cap off the alcohol jug or pours too much into the dishes, fumes can build up and, if exposed to flame, create a flash fire. If the fumes come from an open bottle, the explosion can eject the liquid, followed by a ball of fire. "You get a flame-thrower effect," said Steve Weston, a lawyer representing Burton. The fire marshal in Battle Creek determined Burton's accident could have been prevented if an exhaust system in the room had been used to draw away fumes. And the injuries might have been minimized if the teacher had used a plastic shield or required the students to wear goggles. In many cases, school officials believed such protection was unnecessary when students were watching, rather than participating in, an experiment -- even though most states have laws requiring eye protection under such circumstances. No Safety Training: But a high percentage of science teachers have never had safety training, and in some cases, the schools didn't even own the necessary safety equipment, experts said. Gerlovich, the Drake University researcher, has found, for example, that more than 70 percent of North Carolina science teachers had never received safety training. He said surveys in 17 other states found an average of 55 percent to 65 percent of teachers have never been trained in safety. Alan Paradise, assistant principal of East Bakersfield High School in California, said he never imagined students were in serious jeopardy in the chemistry lab -- until a glass bottle of methanol exploded three years ago, sending a teacher and 22 students to a hospital with cuts, headaches and nausea. After that, the district began requiring shields and goggles and sent teachers to safety training. "We had done this demonstration for years and years without problems," Paradise said. "We're fortunate nothing worse happened." The lack of training is alarming for another reason, experts said: Many teachers don't know how to safely store chemicals, which can cause dangerous reactions if they accidentally mix. Some teachers store chemicals alphabetically instead of by chemical type or they keep them beyond their safe life span. In Rogersville, Tenn., last March, old, unlabeled bottles of chemicals being removed from a school accidentally leaked and mixed, causing an explosion and fire. No one was hurt. In Valley, Neb., officials cleaning out a school lab last year found a canister of picric acid, which crystallizes and becomes highly explosive with age. When they realized it could be 30 years old, they called a bomb squad, which blew up the canister. Still Recovering: Eight months after the Genoa-Kingston flash fire, Rachel Anderson, Eric Baenziger and Kara Butts are still recovering from their burns. Kara and Eric wear pressure garments 24 hours a day to reduce scarring, and both will require skin grafts, said their lawyer, Michael Alesia. The students declined to be interviewed for this story. All eventually returned to school. Administrators are trying to sort out what happened and whether they should change their chemistry procedures. The teacher was not disciplined and remains on staff, according to the school's superintendent, Richard Leahy. The teacher did not respond to a request for an interview, but Leahy said, "No one agonized more than this man over hurting his students. He's a retired professional chemist; he teaches because he loves it." The Genoa-Kingston case illustrates a lack of school safety oversight common in most states, where laws, if they exist, are almost never enforced in schools. Aside from eye protection requirements, few laws are aimed specifically at students. School labs rarely undergo inspections from state or federal authorities and there usually are no requirements that accidents be reported to anyone outside the school. "The schools are pretty much left on their own," said James Kaufman, director of the Massachusetts-based Laboratory Safety Institute, a nonprofit agency that promotes school lab safety. "They all assume these are smart people, they have a science degree, they know how to do this properly. This is not true in some significant measure." Federal Occupational Safety and Health Administration rules do not cover local or state employees, and in most states, similar workplace safety laws apply only to employees. There is no OSHA equivalent to protect students; instead, it is assumed that if laws -- including OSHA's laboratory standards -- protect teachers, students also will be safe, experts said. The Illinois Labor Department, for example, investigates school accidents only if someone reports them, said Al Juskenas, the department's manager of safety inspection and education. But schools are only required to report accidents if someone is killed, or if three or more employees -- not students -- are injured seriously enough to go to the hospital. The department investigated the Genoa-Kingston case because a teacher complained, Juskenas said. As reported in the Salt Lake Tribune, Sunday July 7, 2002 - |
