The California Division of Occupational Safety and Health (Cal/OSHA) last week sent its findings in the investigation of the death of University of California, Los Angeles, chemistry researcher Sheri Sangji to the Los Angeles County District Attorney’s Office. The DA’s office will now review the case and decide whether to file charges against the university or any of its employees.
Sangji, a research assistant in the lab of chemistry professor Patrick Harran, died a year ago after being badly burned in a laboratory fire. Cal/OSHA investigated the incident and subsequently fined UCLA $31,875 for laboratory safety violations related to Sangji’s death.
As is standard practice in the case of a workplace death, Cal/OSHA’s Bureau of Investigations reviewed the case to determine whether there was sufficient evidence of criminal violations of the California Labor Code to warrant referring the case to the DA’s office.

I spent some time this morning updating my list of lab safety incidents so far this year. Although the list is undoubtedly not comprehensive, it would appear that September and October were not good months for lab safety. I’d be curious to know if there’s always a spike in the fall as new students arrive on campuses.
The ACS Division of Chemical Health & Safety has added presentations from the NorthEast Regional Meetings, held in Hartford, Conn., this month to its technical archives. Included are presentations on:
- Chemical Safety Levels as part of risk assessment by Ralph Stuart of the University of Vermont,
- Transferring Air-Sensitive Reagents by Mark Potyen of Sigma Aldrich,
- When the Chemistry Department and EHS Journey Down the Same Road Together by N. Gail Hall of Boston College, and
- Update on Prudent Practices in the Laboratory by Peter Reinhardt of Yale University.
DCHAS also has presentations up from the ACS National Meeting in August.
Last but not least, a terrific video from the University of California, Berkeley, team the Sounds of Science, this time on lab safety. One complaint is that the song lyrics say “Goggles are a must,” but the singer dons glasses. Safety experts say go for the goggles.

The six columns of letters in this week’s print edition of C&EN and several more columns in this week’s edition of C&EN Online all pertain to the death of Sheharbano (Sheri) Sangji, a 23-year-old research assistant in a chemistry laboratory at the University of California, Los Angeles, and C&EN’s coverage of the accident that led to her death.
Associate Editor Jyllian Kemsley has written extensively about the accident, culminating in a major investigative article that appeared in the Aug. 3 issue (page 29). To recap, on Dec. 29, 2008, Sangji was scaling up a reaction she had carried out at least once before to produce 4-hydroxy-4-vinyldecane from either 4-undecanone or 4-decanone. The first step of the reaction was to generate vinyllithium by reacting vinylbromide with tert-butyllithium, a pyrophoric chemical.
The experiment went terribly wrong when the tert-butyllithium spilled and ignited a spilled flask of hexane. Sangji suffered extensive burns on her upper body. She died on Jan. 16.
The letters C&EN has received on the accident focus on several themes. (more…)
Cal/OSHA Investigates UCLA, Again

(Post updated at end.)
The University of California, Los Angeles, is still under the microscope of state regulators. California Division of Occupational Safety & Health (Cal/OSHA) officials paid the school’s chemistry & biochemistry department a surprise visit on Tuesday, Aug. 26.
Cal/OSHA spokesperson Erika Monterroza says that the inspection marked the opening of a new investigation into laboratory health & safety at the university, although she refused to comment on the details of the investigation while it is ongoing, including what prompted it. California law gives Cal/OSHA six months to complete investigations, although the agency usually takes 3-4 months, Monterroza says.

The very first talk I attended on Sunday morning was by Craig J. Thomas from the NIH Chemical Genomics Center. I wandered in in time to see only the last couple of slides, but I was intrigued enough to ask Craig for more details during lunch. That’s because he and his coworkers are collaborating with Lewis C. Cantley at Harvard Medical School and his company Agios Pharmaceuticals. I blogged about Cantley and Agios a little over a week ago- the company is working toward cancer therapies that selectively target key enzymes involved in metabolic pathways, including the glucose breakdown process known as glycolysis.

Some Thoughts on Lab Incidents

Sangji was an avid soccer player and planned to start law school this fall.
C&EN has put out a lot of information this week on the UCLA lab fire that led to the death of Sheharbano (Sheri) Sangji, with the magazine story and accompanying investigation reports, as well as the posts here on the blog. I have a few more thoughts before we wrap up.
First, it’s important to keep in mind that the only reason C&EN was able to get as much information as it did about what happened to Sangji was because the incident occurred at a public university that is subject to public records laws. Most of the reports belonged to UCLA’s fire marshals, fire department, police department, and environmental health & safety office. The notes and reports of people in similar positions at a private school would be unattainable if the school chose not to release them.
Cal/OSHA collected complementary information, but the agency would not have been involved had Sangji been a student. Undergraduate and graduate students, and sometimes even postdocs, are typically not considered to be university employees, even if they’re paid a stipend. Cal/OSHA and similar agencies only have jurisdiction over employees. (On a separate but related note, students also may not be eligible for worker’s compensation.)
Promoting Safe Research Practices

In my story Learning from UCLA, about the laboratory fire that led to the death of Sheharbano (Sheri) Sangji, one of the things that Rick Danheiser, a chemistry professor and chair of his department’s safety committee at Massachusetts Institute of Technology, cautions against is trying to improve laboratory safety in such a way that that you wind up with an adversarial relationship between researchers and environmental health & safety personnel.
Others have warned against being too punitive, since that just encourages people to hide what goes wrong. And as I’ve written before, if you don’t know what happened then you can’t learn from it.
Davis dons goggles, gloves, and a flame-resistant lab coat to do experiments at Dow.
So, if people want to improve the safety culture in their departments, what are positive ways to do it? Anna Davis, a researcher just wrapping up her first year at Dow Chemical, thinks that academic departments could benefit from collaborating with industrial labs on good safety practices. Rohm & Haas, which was recently acquired by Dow, was actually working on a project with the American Institute of Chemical Engineers to develop a safety certification program for academic departments, says Susan Dallessandro, a senior research & development director at Dow. Dow is evaluating how to develop that program within its existing outreach efforts, Dallessandro says.
James Kaufman, director of the Laboratory Safety Institute, suggests that colleges and universities get creative with rewards. “We have lots of ways of telling people they’re doing a bad job but relatively few ways of saying thank you for a good job,” he says. One idea that he has for larger institutions is to have EH&S officers nominate labs they inspect every month for a “safety excellence” award that includes a thank you from top-level administration. Once a year the school’s president could then invite those labs to a lunch at which he or she could personally thank them.
In a report issued last month (pdf), UCLA’s new laboratory safety committee also encouraged the university to develop a reward system to encourage safety compliance in labs. Does your school or workplace make a point of rewarding safe research practices? What positive ways would you suggest to promote lab safety?

Tampering with Evidence?

One of the allegations that has been printed in other media accounts of the lab fire and its aftermath at the University of California, Los Angeles, is that members of Patrick Harran’s lab tampered with the incident scene. Based on documents C&EN obtained through a California Public Records Act request, this seems to be what happened:
Personal Protection from Fire

Posted by Jyllian Kemsley on August 4, 2009 in Chemistry in the News, Safety
When Sheri Sangji was injured in a laboratory fire at the University of California, Los Angeles, the extent of her injuries—second and third degree burns to 43% of her body, as well as heat damage to her eyes—perhaps could have been reduced had she been wearing appropriate personal protective equipment. “Cal/OSHA said the lack of a lab coat was the single most significant factor in the severity of the burns that led to Sangji’s death,” according to a UCLA press release.
But a standard cotton lab coat does not provide much protection from fire, at least not unless the coat can be removed quickly enough to prevent the fire from spreading to the wearer’s clothing, says David Greenhalgh, a professor and chief of burn surgery in the UC Davis Health System and chief of staff for the burn center at Shriners Hospitals for Children Northern California.
Cotton and silk are very flammable, Greenhalgh says, while rayon burns easily but not as intensely, wool is difficult to ignite, and polyesters and nylon tend to melt and limit the spread of flames. He advises that researchers handling flammable materials use special flame-resistant lab coats.
When asked whether Sangji’s injuries could also have been lessened if the laboratory shower had been used to put out the flames rather than a lab coat, Greenhalgh says that the important thing is not how a fire is put out, but how quickly. “Stop, drop, and roll” is still the best approach if a shower or fire blanket isn’t nearby, he says, since running across a room will fan the flames.
Greenhalgh adds that showers are actually not recommended for extensive burns under typical circumstances, because the skin normally provides a thermal barrier and a cold shower can lead to hypothermia in a badly burned victim. In a lab incident, however, a shower may still be necessary for decontamination purposes.
Lab coats, of course, don’t protect your hands. There isn’t an adequate solution for hand protection, says Neal Langerman, the founder of the company Advanced Chemical Safety and a consultant to the American Chemical Society’s (ACS) Committee on Chemical Safety. Truly flame-resistant gloves are bulky, so a wearer loses dexterity and thereby introduces risk of another sort. Many of the people Langerman works with choose to wear lightweight gloves that offer minimal fire protection, accepting that their hands are at risk of getting burned, he says, adding that “I don’t like it but I don’t have a good workaround.” A tight-weave Nomex, Kevlar, or leather-Nomex pilot’s glove will give about 3-5 seconds of skin protection from flames, as well as some protection from flying glass, Langerman says.
Langerman and Harry J. Elston, editor of the Journal of Chemical Health & Safety, will be conducting the ACS Division of Chemical Health and Safety’s “Ask Dr. Safety” session on preventing laboratory explosions at the upcoming ACS National Meeting in DC. Also at the meeting will be a preview of the National Academies’ revisions to Prudent Practices in the Laboratory: Safe Handling and Disposal of Chemicals, presented by William F. Carroll Jr., a co-chair of the Prudent Practices update committee, an ACS past-president, and vice president for chlorovinyl issues at Occidental Chemical.
