College and university sector response to the U.S. Chemical Safety Board Texas Tech incident report and UCLA laboratory fatality
“This report is a an update on the ongoing work by the U.S. Chemical Safety Board (CSB), TTU, UCLA, Campus Safety Health and Environmental Management Association (CSHEMA), American Chemical Society (ACS) and other organizations since the release of the October 19, 2011 CSB investigation report on the TTU incident.”
Proceedings of the 2012 University of California Center for Laboratory Safety Workshop
“The workshop gathered researchers from the public and private sectors, graduate students, university administrators, and health and safety subject matter experts into one meeting with the aim to identify areas where research into laboratory safety could have the greatest and most immediate impact.”
Application of lean six sigma business practices to an Air Purifying Respirator process
“The goal of process management is to understand how the process operates and to collect metrics that allow the process parameters to be adjusted (managed) to ensure nuclear research worker satisfaction. This is accomplished through the use of a process management system, which is used to analyze, optimize, and manage process performance based on meaningful data. This includes identifying process scope and ownership and measuring performance. This paper discusses the application of LSS business practices to a nuclear research APR process and demonstrates how management uses the results to make decisions.”
Pesticide residue in organic and conventional food-risk analysis
“Four groups of pesticides, i.e., organochlorine, carbamates, organophosphorous and pyrethrites were analyzed in wheat and rice samples. Presence of organochlorine pesticide residue was observed in two out of ten organic farms, which were converted from conventional to organic practices few years ago. This was attributed to excessive use of synthetic pesticides. Wheat and rice samples taken from market (conventional farm) showed significant level of pesticide residues.”
A behavior-based observation program’s contribution to a nuclear facility operational safety
“A key element of the H&S Program is to consider measures that lower the risk of operations. The implementation of a behavior-based safety observation program focusing on the identification and elimination of at-risk behaviors is one of these measures. To engage employees in identifying and communicating at-risk behaviors, ATOMICS, a behavior-based safety observation program, has been implemented at [Los Alamos National Laboratory's Plutonium Facility at Technical Area 55]. ATOMICS stands for Allowing Timely Observations Measures Increased Commitment to Safety. A detailed account of this approach to TA-55 glovebox operations has been described previously in this journal.3 TA-55 management provides specific feedback when at-risk behaviors are observed. This enhanced ATOMICS puts additional emphasis on data analysis to identify root causes for injury/illness events. This report contributes to this feedback.”
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.
Yes, I know, my last post was just videos, too. But people are doing some good ones! Behold a typically great video from the University of California, San Diego, on personal protective equipment: Eye and face protection and lab coats.
From UC Berkeley, what happens when you neglect eye protection (at the end, though, even if his eyes are fine, I think that the acid on his head requires a shower):
Courtesy of University of California, San Diego, chemistry lecturer Haim Weizman, here is a new video on personal protective equipment–mostly lab coats, with a nod to eye protection.
So far, two complaints have cropped up on the Division of Chemical Health & Safety e-mail list about the video. One is that it shows safety glasses rather than splash goggles. I agree that goggles would be a better choice, especially when part of the video shows a splash. Safety glasses are really just for impact protection.
The other complaint concerned “the low-cut tank top work by the lab worker.” I agree with this to some degree, because the lab coat doesn’t cover the top of the worker’s chest, either. On the other hand, how much protection would a crew-neck t-shirt really provide? And how much clothing policing is reasonable? UCSD started requiring lab coats in its undergraduate labs a few years ago precisely because it was difficult to enforce a dress code. “Our explanation of what was appropriate attire was a huge paragraph and had to be constantly changed” as fashions evolved, teaching labs safety coordinator Sheila Kennedy told me in 2010. If chest protection is such a concern that you might want people to take a ruler to their collarbones, then perhaps the answer lies in lab coat design rather than dress codes.
This week’s issue of C&EN includes a story by Celia Arnaud about proposed changes to the ACS Guidelines for Bachelor’s Degree Programs, which are developed by the Committee on Professional Training. The issue also has a comment by committee leaders Anne B. McCoy of Ohio State University and Ron W. Darbeau of Louisiana’s McNeese State University.
Included in the changes are revisions to the safety requirements. Former committee leaders told me a few years ago that the last guidelines revision, completed in 2008, had more explicitly addressed safety than earlier versions, so the newly-proposed revisions take the criteria a step further.
Here’s what the requirements say now in the safety section:
7.3 Laboratory Safety Skills.
Approved programs should promote a safety-conscious culture in which students understand the concepts of safe laboratory practices and how to apply them. Programs should train students in the aspects of modern chemical safety appropriate to their educational level and scientific needs. A high degree of safety awareness should begin during the first laboratory course, and both classroom and laboratory discussions must stress safe practices. Students should understand responsible disposal techniques, understand and comply with safety regulations, understand and use material safety data sheets (MSDS), recognize and minimize potential chemical and physical hazards in the laboratory, and know how to handle laboratory emergencies effectively.
And here’s what’s proposed (overall, there’s a shift from “shoulds” to “musts”):
Section 7.3 Laboratory Safety Skills (p. 14-15)
Programs must train students in the aspects of modern chemical safety appropriate to their educational level and scientific needs. Approved programs must promote a safety-conscious culture in which students understand the concepts of safe laboratory practices and apply them.
- Programs must train students in the aspects of modern chemical safety appropriate to their educational and scientific needs.
- The promotion of safety awareness and skills must begin during the first laboratory experience and be incorporated into each lab experience thereafter. Classroom and laboratory discussions must stress safe practices. Students should be actively engaged in the evaluation and assessment of safety risks associated with laboratory experiences.
- Safety understanding and skills should build throughout the curriculum and be assessed.
- Students should
- understand responsible disposal techniques
- understand and comply with safety regulations
- understand and use material safety data sheets (MSDS)
- recognize and minimize potential chemical and physical hazards in the laboratory and know how to effectively handle laboratory emergencies.
- Students must undergo general safety training as well as lab-specific training before beginning undergraduate research.
- Approved programs must have an active, departmental safety committee.
What say you, readers? Are the proposed changes necessary or sufficient? What would you add or subtract?
From McCoy and Darbeau’s piece this week: “Please send comments to by Aug. 1 so they can be discussed at the next CPT meeting. The committee will also hold an extended open meeting on Sept. 8 at the ACS national meeting in Indianapolis that will focus on the guidelines revision. Details will be posted on the CPT website. CPT plans to publish the new guidelines in 2014.”
Several weeks ago, a request hit my inbox: Did I know of a library of lab safety videos? I didn’t. But it seemed like one would be a useful resource, so Russ and I set about putting one together. It’s just a spreadsheet, but hopefully it’ll be useful to some in the chemistry community:
Lab Safety Videos
A few notes:
- Video descriptions are courtesy of Russ (thanks, Russ!)
- We make no guarantees about quality
- There are undoubtedly videos that we missed. If you know of one we should include, feel free to post it in the comments or
- Likewise, if you or someone you know produces a new video, let us know to add it!
The spreadsheet is freely available to anyone who would like to use it, for whatever purpose. That includes making a prettier, more accessible version. Legendary chemistry librarian Dana Roth of Caltech, for example, has started a Safety Videos “LibGuide.”
I know, the Safety Zone has been very quiet of late. I was busy working on a cover story about the Deepwater Horizon oil spill, plus a companion piece on oil dispersants. We’ll resume regular programming with a round up tomorrow.
Yesterday at the Council for Chemical Research meeting, Dow unveiled a publicly-accessible website with a comprehensive set of lab safety training videos plus additional resources. The website is at safety.dow.com. More details on the development of the site are in my C&EN story on the project. One tidbit that didn’t make it into the news story: While the video hosts are professional actors, the supporting roles are played by Dow scientists.
Research Day is an annual department tradition going back at least a decade, says department chair Nicole S. Sampson. Students prepare posters about their research, the department hosts a lunch, and one of the faculty members gives a keynote lecture. “Undergrads and other faculty wander through and find out what’s going on in the chemistry department,” Sampson says.
Last year, it was scheduled in early November, the week after Superstorm Sandy hit the East Coast. Although the university suffered minimal damage from the storm, the school cancelled classes for several days and Research Day was postponed until January.
Meanwhile, Sampson says, she had already been pondering how to elevate people’s safety consciousness. As everyone returned to work after the storm, she organized a joint meeting with the Research Day and safety committees, and Research Day took on a new safety component. “We got really excited about it, says Jonathan G. Rudick, a chemistry professor and one of the Research Day organizers. “It was a great way to get something new into a well-trod tradition.” he says.
Adds Sampson, “You can only tell people so many times to be safe. We decided that we had to find another way to say that it’s important to the university and to get people to stop and think about what they do every day.”
The plan the department came up with was to have students develop safety demonstrations related to their research. Members of the department would then vote for their favorite demos, and the winners would receive a prize. Prior to the event, lab safety specialist Kim Gates reviewed demonstration ideas and written protocols to make sure students followed best practices, then visited the labs to see the demos in person and ensure the labs could accommodate visitors.
One of the demonstrations that won an award was a presentation on a waste handling system for radioactive 32P work. Liquid waste gets filtered to remove 32P, which gets concentrated to reduce the waste volume. “It’s a very nice set-up,” Sampson says.
The other award-winning demo showcased permeability of different types of gloves to various solvents. The group dyed the solvents so observers could see them migrating through glove material to paper on the other side.
Additional demos included using solvent purification push stills, ultracentrifuges, and glove bags; moving compressed gas cylinders; handling ethidium bromide; transferring butyllithium reagents; quenching metal hydride reagents; and “find-the-hazard” on a benchtop. One of Rudick’s favorites was hands-on instruction for how to remove gloves, using ketchup as a contaminant. The department also gave prizes for the two cleanest labs.
Additionally, Gates arranged for an expo with several vendors to exhibit safety equipment and perform a few additional demos. She had her own table to display lab photos she’d taken over a few years. Students had to identify 10 incorrect things in the photos, and their answers went into a raffle for another prize.
Overall, department members were very enthusiastic about the safety demos and the day went better than expected, Sampson and Rudick say. But between the usual Research Day events and the safety demonstrations, they agree that they had too much happening—neither Sampson nor Rudick actually made it to see everything. In the future, the department will hold separate annual research and safety events. For the safety day, Sampson and Rudick also want to pare down the number of demonstrations so there’s time to see everything. Even if individual researchers don’t do the chemistry in question, Sampson sees value in exposing them to it. “The laser jocks who come in to hang out with the people running ethidium bromide gels need to know what’s going on in that lab,” she says.
A note from Jyllian: I get a lot of questions from people asking how to be positive and proactive about safety rather than punitive and reactive. If your group or department is doing something that others could find useful, please get in touch!
