The University of Minnesota chemistry department released a new promotional video last week. The department sets a pretty high standard for showing proper personal protective equipment. I spy only one person who is obviously in a wet lab without eye protection.
UMN was one of the schools involved with Dow in the company’s safety partnership with universities. They now have a paper out in the Journal of Chemical Education, so you can read about their experiences in their own words (J. Chem. Educ. 2013, DOI: 10.1021/ed400305e).
Chemical health and safety news from the past few weeks:
- On Nov. 20, UCLA chemistry professor Patrick Harran had a status check with the judge regarding felony charges of labor code violations that led to the death of researcher Sheharbano (Sheri) Sangji. The result of that status check was another status check scheduled for Jan. 10, 2014. Harran’s preliminary hearing concluded on April 26. We’re going on two years since charges were filed on Dec. 27, 2011, and five years since the Dec. 29, 2008, fire.
- On Nov. 1, former UC Davis chemist David Snyder was arraigned on felony charges of reckless disposal of hazardous waste, possession of a destructive device or explosive, possession of materials with intent to make a destructive device, and possession of firearms on university property. The charges relate to an explosion in his campus apartment nearly one year ago. Snyder’s preliminary hearing concluded on Oct. 10. Snyder is scheduled for a trial-setting conference on March 17, 2014, and a jury trial to start on March 24, 2014.

- Residents near an Allenco Energy oil field in Southern California have been complaining for three years about fumes from the site. At Sen. Barbara Boxer’s request, EPA investigators visited the site in October. “I’ve been to oil and gas production facilities throughout the region, but I’ve never had an experience like that before,” [EPA regional administrator Jared] Bumenfeld said. “We suffered sore throats, coughing and severe headaches that lingered for hours.” No word on what’s happened since.
- Also in California, state regulators are supposed to match hazardous material origin paperwork with what arrives at disposal sites. They don’t. “These so-called lost loads include more than 20,000 tons of lead, a neurotoxin; 520 tons of benzene, a carcinogen; and 355 tons of methyl ethyl ketone, a flammable solvent some in the industry call ‘methyl ethyl death.’” (I’m curious to know what chemists think of that nickname. It’s flammable, yes, but it’s not ranked category 1 for any GHS hazard class.)
- And, er, ALSO in California, a waste mystery: “more than 100 metric tons of the banned pesticide DDT and industrial compounds known as polychlorinated biphenyls, or PCBs, have vanished from one of the country’s most hazardous sites, almost a 90% drop in just five years. Scientists are at a loss to explain the decline across the 17-square-mile site, which sits about 200 feet below the ocean surface and two miles off the Los Angeles County coast.” The chemicals wound up there from industrial waste dumped into sewers.
Fires and explosions
- A Sinopec oil pipeline in China ruptured, then “oil that entered local rain drainage pipes exploded“;
so far reports say that 35 people have died and 166 are injuredMONDAY UPDATE: CNN reported late Friday that 44 people were killed and at least another 135 were injured
- An explosion and fire in a cracking unit at a Chevron refinery in Mississippi killed operator Tonya Graddy
- A massive fire at a Southern Energy facility in Tennessee seems to have started when a methanol tank overflowed and something sparked
- “Accidental ignition” was reportedly the cause of an explosion at Aerojet Rocketdyne in California; one employee is hospitalized
- An employee “moving chemicals” may have caused a spark that led to a fire at Chemical Technology in Michigan; no one was injured but homes, a school, and other businesses were evacuated
Leaks, spills, and other exposures
- A 20,000-gal tank of liquid…something…overpressurized and launched itself through the roof of American Vinyl Company in Florida; one employee died and was found covered in a yellow liquid, while five others were injured

The preliminary hearing for former University of California, Davis, chemist David Snyder on explosives and weapons charges was scheduled to continue today in Yolo County Superior Court. Snyder’s defense attorney is recovering from surgery, so the hearing was postponed to Oct. 4.
In this week’s issue of C&EN, I have a story on how the University of California is implementing and expanding upon the lab safety settlement agreement that UC made with the Los Angeles County District Attorney’s Office last summer. In short, UC is taking the legal mandates for chemistry and biochemistry departments and expanding them to all research and teaching laboratories as well as to technical areas such as store and stock rooms. Go read the story for details.
Included with the story is a list of links to things such as UC’s new online “Laboratory Safety Fundamentals” training program, UCLA’s personal protective equipment (PPE) inspection checklist, and the system’s new policies on training, PPE, and minors in labs. As part of reporting on the story, I went through the safety fundamentals training and scored 19/20 on the test at the end. If readers are inclined to do the same, be warned that it will take about three hours, at least if you click through the various bits to get additional information.
UC also purchased personal protective equipment for researchers, including 115,000 lab coats. Part of that purchase involved special-ordering flame-resistant, NFPA 2112-rated lab coats from Workrite in small sizes tailored for women. I don’t see them available now on the company’s website, but clearly it at least has patterns. I don’t know whether Workrite is willing to make more, but it’s probably worth a call if you’re looking for some.
Speakers for the open part of the meeting include Massachusetts Institute of Technology chemistry professor and safety committee chair Rick L. Danheiser. I spoke with Danheiser about MIT’s safety program for “Learning from UCLA.” Also on the agenda is William B. Tolman, chair of the chemistry department at the University of Minnesota and one of the people involved in Dow’s academic lab safety partnerships. And then there’s Susan S. Silbey, who is head of anthropology at MIT and studies “the creation of management systems for containing risks, including ethical lapses, as well as environment, health and safety hazards.”
I can’t attend the meeting, but if anyone else who does would like to recap it for the Safety Zone, please let me know!

A Los Angeles County Superior Court judge today denied three defense motions that could have dismissed a criminal case against University of California, Los Angeles, chemistry professor Patrick Harran. With the rulings going against the defense, the case moves closer to trial. The judge set the next court date for Oct. 3. Harran could go to trial within 60 days of that date.
Harran faces four felony charges of violating the state labor code. The charges stem from the death of research assistant Sheharbano (Sheri) Sangji after a 2008 fire in Harran’s lab. In November and December, 2012, Judge Lisa B. Lench heard testimony in a preliminary hearing on the case. She ruled in April that there was sufficient evidence to send the case to trial. After the preliminary hearing, the case was sent to Judge George G. Lomeli for trial.
Before today’s hearing, Harran’s attorneys submitted three motions: one asking the judge for a so-called Franks hearing, another called a demurrer, and a third to dismiss the charges based on lack of probable cause. The district attorney’s office replied to each motion, and the defense then responded in writing to those replies.
In court today, the judge started by asking the defense and prosecution to go to chambers to discuss the Franks hearing motion. The hearing is often used to throw out warrants, such as search or arrest warrants, on the grounds that the police or district attorney obtained the warrant using false statements. In this case, the defense argued that Harran deserved such a hearing in part because David Higuera, a senior investigator for the Los Angeles County District Attorney’s Office, allegedly omitted key information from his affidavit for an arrest warrant for Harran.
My apologies to regular readers and my colleagues at C&EN for my month-long silence at the blog. I saw cobwebs on my laptop screen when I opened the back end this morning. Part of my hiatus came from complications of an infected molar extraction and my inability to concentrate. I’ve also been trying to take short Internet holidays over the last two months because all of the political nonsense in my state is negatively affecting my mental health.
But the tooth canyon is about 50% healed and our state legislature has finished, for now, shifting progressive North Carolina toward its pre-Research Triangle Park level of ignorance, racism, and poverty.
During this month, I came across an excellent post on the Scientific American Guest Blog by Atlanta-based science journalist, Kathleen Raven. In “Ada Yonath and the Female Question,” Raven discusses her experience at this year’s Lindau Nobel Laureate meeting — dedicated to chemistry — and her reflections on hearing and attempting to interview the 2009 Nobelist in chemistry, Dr. Ada Yonath.
Yonath, a structural chemist recognized for her extensive work in showing how the ribosome catalyzes protein synthesis, has generally not made much of the fact that she’s only the fourth woman to receive the Nobel Prize in Chemistry, and the first since Dorothy Hodgkin in 1964.
As I did back in 2009 when interviewing Yonath at the North Carolina Biotechnology Center, Raven debates whether focusing on Yonath as a female scientist is a good thing for the cause of women scientists. Should we focus only on the accomplishments? Or should we focus on her accomplishments in the context of the distinct barriers often facing women scientists?
I’m equally torn, particularly since my 20-year laboratory career was advanced by a group that consistently ranged from 75% to 100% women. I never specifically recruited women to my laboratory but it seems that they might have self-selected for reasons not known to me. My activism in diversity in science extends back to my pharmacy faculty days at the University of Colorado where I assisted in selecting minority scholarship recipients for a generous program we had from the Skaggs Family Foundation.
The goings-on in North Carolina politics is not germane to this scientific discussion. We can speak all we want about our modern society being post-racial and having more women leaders than ever. But voter laws that disproportionately disenfranchise African-Americans and legislation that severely compromises women’s reproductive health tells me that we still need to pay attention to the influence of racial and gender attitudes.
Heck, even our Governor Pat McCrory showed his true colors yesterday while protestors, primarily women, were holding a vigil marking his signature of restrictive abortion legislation: He stepped out of the governor’s mansion to give protestors a plate of cookies and quickly returned behind the iron gates without any substantive engagement.
I’d be interested to hear from CENtral Science and C&EN readers after reading my own interview with Ada Yonath. Should we still be making an issue of advances in race, gender, and sexual orientation in chemistry?
I think yes, and it’s never been more important.

Last week in Stockholm (and Oslo), the 2009 Nobel Prize winners were gloriously hosted while giving their lectures and receiving their medals and diplomas. In Chemistry this year, the Nobel was shared by Venkatraman Ramakrishnan, Thomas A Steitz, and Ada E Yonath for their studies on the structure and function of the ribosome, a remarkable nucleoprotein complex that catalyzes the rapid, coordinated formation of peptide bonds as instructed by messenger RNA. My post on the day of the announcement in October was designed to counter the inevitable (and now realized) criticisms that the prize was not for “real” chemistry.
Only ten days later, we in the NC Research Triangle area were very fortunate to host Dr Yonath at the North Carolina Biotechnology Center for the Symposium on RNA Biology VIII, sponsored by The RNA Society of North Carolina.
Among the many noteworthy speakers was Dr Greg Hannon from Cold Spring Harbor Laboratory, a scientist who some feel was overlooked for the 2006 Nobel Prize in Medicine or Physiology, one where Andrew Fire and Craig Mello were recognized for RNA interference and gene silencing.
NC Biotech’s Senior Director of Corporate Communication, Robin Deacle, kindly invited me to an audience with Dr Yonath and two science reporters following Dr Yonath’s lecture. As you might suspect, I was quite honored to visit for awhile with the woman who defied the naysayers and successfully crystallized a bacterial ribosome, then used X-ray crystallography to determine its structure below three angstroms resolution. The fact that she also used natural product antibiotics to stabilize ribosomal structure added to my magnitude of admiration.

Former University of California, Davis, chemist David Snyder appeared in court on Friday to begin his preliminary hearing on 17 felony charges relating to a January explosion in Synder’s campus apartment.
The charges are for reckless disposal of hazardous waste, possession of a destructive device or explosive, possession of materials with intent to make a destructive device, and possession of firearms on university property. Snyder was released from jail in February on $2 million bail. Snyder was working as a postdoc at the time of the explosion; he’d received his Ph.D. in chemistry from UC Davis in 2011.
The purpose of the preliminary hearing is for a judge to rule on whether there is enough evidence to take the case to trial. Deputy district attorney Martha Holzapfel called eight witnesses:
- Joanne Zekany, UC Davis police detective
- Lee Benson, City of Davis police officer
- Scott Allen, City of Davis police officer
- Paul Henoch, UC Davis police sergeant
- Kevin Skaife, UC Davis police detective
- Daniel Powell, City of Davis police sergeant and member of the Yolo County bomb squad
- Brian Parker, Bureau of Alcohol, Tobacco, Firearms, & Explosives special agent
- Jason Winger, West Sacramento police sergeant and member of the Yolo County bomb squad
The court got through direct testimony of all eight witnesses on Friday. The judge scheduled the hearing to resume with cross-examination of Jason Winger on Friday, September 6.
