In-Reply-To: [DCHAS-L] I Remember When…”: Reflecting on the Evolution of Laboratory Safety
Fifty-three years ago, I went to work for Dow Chemical. On that first day, I learned more about safety than I had learned in 25 years in school.
Two weeks later, I turned my round-bottom flask with a condenser and a calcium chloride drying tube into a Roman candle with purple flames and black smoke. Everyone (50 employees) was out on the lawn looking at me and asking what I had done. No one was injured.
The next morning, we were all in the conference room. The lab director said: “We want to thank Dr. Kaufman for his display of pyrotechnics. But we hope he’ll confine it to the 4th of July.” I wanted to hide under my chair. Then, he added: “We pay you to do three things. Work safely, do your research, and write your reports and patent disclosures.”
Working safely wasn’t something extra. It was one of the primary colors. It was integral. It was important.
Two weeks later, I was driving home to my apartment in Marlboro. I heard on the radio that there had been an explosion at WPI. I drove back to Worcester to Goddard Hall. I walked up to the second floor to the lab. The fluorescent lights had been blown off the ceiling. The windows had been blown out. The corner of the stone-topped bench with the oak cabinets underneath was gone. It looked like someone had passed a hot knife thru butter. And, a grad student had blown off parts of both hands doing six things that I had learned at Dow on the first day that you just don’t do.
As I looked around, I realized that there was no way that my 25 years in school had prepared me to work up to the standards of Dow Chemical. I decided to try to share what I was learning at Dow with schools and colleges.
My supervisor encouraged me to write some lab safety guidelines. I did. I wrote “Laboratory Safety Guidelines”. Dow sent the publication to 2000 colleges and universities in the mid-seventies. Within one year, Dow had received requests for a quarter of a million reprints. We had struck a nerve in academia.
Today, more than six million copies of those guidelines have been distributed in 23 languages. Guideline #11 is four simple questions: What are the hazards? What can go wrong? What do you need to do to be prepared? And, what are the prudent practices, protective facilities and protective equipment needed to minimize the risk. Guideline #11 is the great grandfather of RAMP.

--- For more information about the DCHAS-L e-mail list, contact the Divisional membership chair at membership**At_Symbol_Here**dchas.orgAs we celebrate 150 years of the American Chemical Society, June has been dedicated as the ACS Safety Pillar. I would like to invite members of this vibrant and highly knowledgeable community to join ACS staff in recognizing the remarkable evolution of laboratory safety, becoming a central and integral part of both chemistry education and research.
As scientists, we value data, but stories are also powerful indicators of meaningful and ongoing change.
We would love to hear your perspective.
- How has laboratory safety changed over the course of your career, whether over the past 30, 20, or even 5 years?
- What stands out most to you about this transformation?
Let’s explore this evolution through a personal lens, perhaps by sharing an “I remember when…” moment that captures how practices, expectations, or culture have shifted over time. These reflections can bring our collective progress to life and resonate deeply across our community.
I’m confident there are many powerful stories among us so let’s uncover them together!
One of my stories:
I got my undergraduate degree in Poland, and one of my professors had quite the dramatic introduction to lab safety: he was missing a finger due to a refrigerator explosion in his lab. Our class had about 100 students, and lectures were held in a huge auditorium. During the very first lecture, he proudly displayed his incomplete hand and declared that we were all very brave for choosing chemistry as our future profession. According to him, true scientists should be prepared to make sacrifices at the altar of scientific discovery.
I remember sitting there thinking that perhaps I was not ideal chemist material, since I had no intention of sacrificing any body parts in the name of science.
Of course, after that first lecture, we all laughed about this safety demo, but the professor himself was completely serious. He wore his injury almost like a badge of honor , proof of his “scientific stamina.”
Years later, I heard that his lab was eventually shut down because the refrigerator explosions kept happening, and one of them even destroyed a very expensive piece of instrumentation. I believe he retired shortly after that ban. In hindsight, perhaps the university finally decided that repeated explosions were not an essential component of scientific freedom.
Looking back, what once may have been seen as a “badge of honor” now feels more like a reflection of poor safety practices and a lack of professional responsibility. Today, a faculty member proudly displaying injuries from preventable laboratory accidents would likely be viewed not as a scientific hero, but as a liability to the institution. I hope that, thanks to all our collective efforts, our discipline is evolving. Modern chemistry starts recognizing that good scientists are not the ones who cause and survive accidents; they are the ones who create strong safety cultures so accidents do not happen in the first place.
