La Cucaracha

La cucaracha, la cucaracha,
Ya no puede caminar…

dead_cockroach

I stumbled upon this lovely scene in the men’s room by my lab last night.

At some point in every single laboratory I’ve ever worked, I’ve encountered a dead cockroach lying flat on its back. Without exception, my first thought is always:

What horribly toxic substance has this poor creature encountered to cause her
to die alone and out in the open like this?

After a few seconds of thoughtful reflection, I usually convince myself the cockroach died of natural causes and we are all safe. In other news, I wish I could say that I’ve never seen a labmate do this:

Fortunately, I haven’t had the excitement of seeing a live one racing around the floor in a long time.

The Most Important Lesson from Sheri Sangji’s Death

Thursday, June 26th, 2014

Chemical Ed with GogglesThis post on The Safety Zone indicates that the community is already forgetting many of the details and lessons of Sheri Sangji’s tragic death. That is a shame, but not a surprise considering the high turnover in academic labs. If I had to pick the most important thing to remember from the tragedy, it is:

When you are covered in hazardous material or flames,
GET IN THE SAFETY SHOWER

It does not matter if the material is pyrophoric. Just get in. Take off your clothes. Don’t rub your skin; simply let the material rinse away. Do not worry about flooding the lab—your department is going to have way bigger problems if you are seriously injured than if you flood the building. Just look at what happened to UCLA.

If you see a labmate covered in flames or hazardous material, physically help him (i.e., drag him) to a safety shower. Chances are he is panicking and not thinking clearly. Don’t think that you can extinguish the flames with a blanket or lab coat. Don’t waste time worrying about what the substance is. Just get the victim in the damn shower and pull the chain, then call for an ambulance. Help him remove his clothes. Keep him in the shower for 15 minutes. Be a good friend and find some spare clothes or a blanket so he can shield his bits and pieces from public view.

For all the time we spend talking about whether a lab coat would have saved Sangji’s life, I think using the safety shower would have made a much bigger difference.

UCLA Professor Patrick Harran Strikes Deal with Prosecutors

Sunday, June 22nd, 2014

BulldoodyPatrick Harran, the UCLA professor who faced four felony counts in connection with the death of Sheri Sangji in a laboratory fire, has struck a deal with prosecutors that allows him to avoid charges in exchange for a $10,000 fine, 800 hours of community service, and running a lab free of safety violations. So long as Harran completes his end of the terms of the agreement, he will avoid trial and have an untarnished criminal record.

What a relief!

As an assistant professor in charge of a research lab, I could not be happier with this outcome. I have a lot of stuff to worry about, and ensuring the safety of my students cannot be allowed to get in the way of important things like finding consulting gigs, collecting awards, traveling to international conferences, and stealing ideas for grants. All of those OSHA rules are meant for industry, not academia. The bar for what passes as safe in academic labs is clear, and people who want to work under moderately safe conditions know better than to go to graduate school. The government simply can’t expect me to be responsible for what happens in my lab, which is well over 50 feet from my office and not even the same direction as the restroom. I’m happy to buy enough safety goggles and almost enough lab coats to outfit my students, but the rest is up to them. If Aldrich has written a technical note on their hazardous experiment, my students know not to bother me.

The most important aspect of the Harran deal is how it extends the long, proud tradition of excusing PIs of any professional responsibility for their work. Society recognizes that professors are only supposed to have good things happen to them. We get the lion’s share of credit for papers, not the students or postdocs. We get the big salaries, not the students or postdocs. We get the awards, not the students or postdocs. On the flip side, professors must be protected from negative consequences at all costs. If an accident happens in one of our labs, that’s the students’ fault. If multiple papers from one of our labs contain fabricated data, that’s the students’ fault as well. Clearly, professors are not responsible for supervising their groups for integrity or safety. We know this because Dalibor Sames and Patrick Harran are still in charge of their labs. I applaud Columbia and UCLA for recognizing that you can’t discriminate against professors for trivial things like irresponsibility and incompetence. Anyway, it’s the competent professors you need to watch—lightning never strikes twice, right?

Of course, I realize that there should be some consequences when something truly horrible happens. In these situations, professors must arrange for perfunctory punishments that allow all of the parties charged with oversight to save face. That’s what we saw here: UCLA threw some money at a scholarship in the victim’s name and at establishing a safety program it should have had in the first place. Personally, Harran was forced to donate money to the hospital where his student died. Incidentally, I think $10,000 was way too much; the man only earns $301,000 a year. How is he going to make ends meet with just $291,000? At least Harran’s lawyers were clever in how they disguised the 800 hours of community service as a major inconvenience instead of court-mandated preparation for the Broader Impacts section of Harran’s next NSF proposal. Killing two birds with one stone is exactly why good lawyers get paid the big bucks.

In all seriousness, I think the deal agreed to by prosecutors is a grave injustice, but one that comes as no surprise in today’s legal system. Without any changes to the material facts of the case, how does the DA go from charging someone with four felony counts to striking a deal that allows Harran to have a spotless record with a payment, community service, and actually doing his job of running a lab free of safety violations? Note that this was not a plea bargain; Harran pleaded guilty to nothing—not a misdemeanor, or even an infraction.

The game plan of Harran’s legal defense was quite effective: delay, delay, and delay. They gummed up the works with continuance after continuance and motion after motion. In the end, it appeared the prosecutors were willing to do anything just to clear the case. I mean, was this deal what the prosecutors were holding out for all of these years? What makes it all the more worse is that the original deal called for 400 rather than 800 hours of community service. The judge had to step in and double it.

My heart goes out to Sheri’s family for their loss. While I think our legal system has denied them justice, my hope is that the field of chemistry does not forget what happened to her. I hope UCLA’s reported new-and-improved safety culture persists, and I hope the rest of the world of academic chemistry also strives to do a much better job regarding safety than it has in the past. At the very least, I can guarantee you that Sheri’s death has had an indelible, positive effect my approach to safety and how I manage my lab and students.

Gas Cylinders on Fire

Monday, July 15th, 2013

Everyone has heard stories of ruptured gas cylinders rocketing across the floor (and through walls), but seldom does one get to witness such an accident. Recently, a truck transporting a load of cylinders crashed on a Russian freeway and created this scene:

There were several other videos taken from a variety of angles (1 2 3). It’s interesting to watch one cylinder explode after another and to see the kind of speed a ruptured container can build. Obviously, these ubiquitous and relatively inconspicuous pieces of lab equipment present serious risks.

Nice…

 

Of course, it’d be even nicer with safety glasses.

Also, beautiful new labs. Yum.

Teacher Sets Fire to Himself

 I’m really not sure what the point of the demo was.
