Yale Student Killed as Hair Gets Caught in Lathe


By LISA W. FODERAROAPRIL 13, 2011

As a Yale undergraduate majoring in astronomy and physics, Michele Dufault was used to extreme physical environments. She worked on underwater robotic vehicles last summer as a fellow at the Woods Hole Oceanographic Institution in Massachusetts. She also traveled to Houston as part of a team of undergraduates chosen by NASA to perform a plasma physics experiment in reduced gravity.

But it was a rudimentary machine — a lathe in a campus laboratory — that erased what everyone imagined to be a brilliant future for Ms. Dufault, who also found time to mentor girls interested in science and to play saxophone in Yale’s precision marching band.

On Tuesday, just weeks from graduating, she toiled late at night inside a machine shop in a chemistry lab, as she had for weeks while working on her senior thesis: investigating the possible use of liquid helium for detecting dark matter particles. Ms. Dufault, 22, was killed when her hair became caught in the lathe, whose rotating axis is used to hold materials like wood or metal being shaped.

Students and staff members were overwhelmed by the news on Wednesday, and met in small groups to share their grief. Linda Koch Lorimer, a Yale vice president and its secretary, called the death a “terrible accident” in a letter to students, and said counselors were available. A candlelight vigil was held Wednesday night in the courtyard of Saybrook College, the residential complex where Ms. Dufault lived on the New Haven campus.

“She was incredibly passionate about every sort of science,” said Joe O’Rourke, a fellow astronomy and physics major and member of the physics team. “She was the hardest-working person I know.”

Connecticut’s chief medical examiner ruled the death an accident, citing the cause as asphyxia due to neck compression. The federal Occupational Safety and Health Administration said it would investigate; Ted Fitzgerald, a spokesman for OSHA in Boston, said the agency had jurisdiction over the lab because Yale employees also use its equipment.

Yale’s president, Richard C. Levin, said in a statement that the university would also review “the safety policies and practices of laboratories, machine shops and other facilities with power equipment” operated by undergraduates, in both science and arts buildings. Until the review is complete, he said, undergraduates will have access to those places only during set hours, and monitors will be present.

Mr. O’Rourke said the machine shop in Sterling Chemistry Laboratory, which he also uses, always had a staff member present during daytime hours. But many students use the shop at night; Dr. Levin said that other students who were working in the building found Ms. Dufault’s body and called the police.

The chemistry department’s Web site says access to the machine shop is “strictly limited” to those who have completed an introductory shop course. Yale lists safety precautions online for another machine shop on campus, warning students: “If you have long hair or a long beard, tie it up — If your hair is caught in spinning machinery, it will be pulled out if you are lucky.”

Ms. Dufault was taking an advanced course on machine shop protocols this semester, Mr. O’Rourke said. And for the NASA reduced-gravity experiment, she helped write a 60-page document on safeguards.

“She’s always been very careful,” he said. “That’s why I was shocked that this happened. I worked with her in that lab and always saw her taking the safety precautions.”

Manfred Philipp, a chemistry professor at Lehman College in the Bronx, who had no direct knowledge of the Yale accident, said lathes and similar equipment were notoriously hazardous.

“You have to be really careful around a machine like this because it has immense power,” he said. “The lathe has revolving moving parts, and if your hair gets stuck in that, then your head would be pulled toward the machine.”

Ms. Dufault, who grew up in Scituate, Mass., had planned to pursue a graduate degree in ocean science. At the Noble and Greenough School in nearby Dedham, she was remembered as “one of the most precocious students whom her teachers ever encountered.”

“Her mind, her sense of curiosity, her perceptiveness, her sensitivity and her enjoyment of what she did were extraordinary,” said Robert P. Henderson Jr., the head of school. “She was a true intellectual.”


Correction: April 16, 2011

An article on Thursday about a Yale student who was killed in a lathe accident in a campus laboratory misstated the location of Lehman College, the employer of a professor who was quoted about the danger of lathes. It is in the Bronx, not Queens.

You hear about young people dying while doing crazy antics - wingsuiting, climbing tall buildings, etc.

It doesn't hardly seem fair that some 22 year old college student trying to make something on a lathe to help her do science, should suffer the same type of death.

I try to be vigilant, but these machines we use can hurt you easily. They can kill you instantly, sometimes when you least expect it. The other day I removed a pressurized air hose from a quick connect and the hose instantly flew back into my face and the metal fitting hit me just under the eye. No time to react, my eye would have been gone if it hit 1 inch higher. I got lucky that day, and many others. I could stop, and never work in the shop again, or I can go forward and try to be more careful.

Back in 2001 I had a ladder accident. I was replacing wood trim on a second story window, working off a lightweight 16 ft. aluminum ladder on uneven ground. Well, the ladder shifted and distorted into a parallelogram shape, sending me for a short flight. I broke a couple ribs and shattered my wrist, requiring fitment of an external fixator, a piece of carbon fiber tube with aluminum clamps at each end, drilled and pinned into my forearm and back of my hand.
Finally, after 2 months of serious inconvenience, it was time for it to be removed. Raising my arm, I asked the surgeon " Do I own this equipment, or did I just rent it"? His reply was "Why do you ask"?
I said "Have you ever watched any of the home improvement TV shows?" Before starting a project, they always mention some type of reminder about to know and follow all shop safety procedures. This is going on the wall above my workbench as a reminder to do just that."
He said "I'll have it returned to you".
It's still on the wall as a lifelong reminder.

Young or old, every day I still regret losing the feeling in my right fingertip because of a careless moment with a table saw. The more reminders we get, the better.

Safety PPE, we are all guilty of NOT using it...
Safety Glasses don't LOOK cool but at least you can SEE that you don't look cool!
Gloves and Saws/grinders/other tools.
Mash the E-Stop when working on equipment Lock out Tag out Clear and Try, some machines have stored energy that can be released when powered down.

I recall a man who got pulled into a 15" lathe when working by himself and his shirtsleeve got caught on the workpiece while moving at 7000 RPM... didn't take long to reel him in and he was never able to hit the E stop...

I recall a young man who was turning the end of a long piece of 1" bar in a lathe, and he didn't have a support under the infeed end of the material or more to Capture it and he leaned over in that direction just as the wobbling end of the material bent 90 degrees and came around and hit him in the head.

Place I used to work had warnings about frozen explosives, we had MANY MANY things on the grounds that could kill you DEAD before you knew anything had happened.

We has an explosion in a building where explosive residue had been allowed to build up around a piece of equipment, a crew came on site to do some work on that machine safety "Cleaned" and sanitized it... well what they COULD the buildup was inside some tubular structure, he was cleared for hot work so he bagan to drill a hole in one of the legs of the structure to bolt on what he had to do... BOOM! no joke several of the plant personnel witnessed the explosion and ensuing fire and ran in there. grabbed the guy and put him out and then dragged him away from the blowtorch... he survived... barely 2nd and third degree burns... yeah if you have to decon something be sure to check EVERYWHERE... not just the outside!

I've known of folks getting hit with fork trucks, an explosive mix house blew up killing the occupants... the explosive has to be kept WET while mixing if it dries out then it will go BOOM... in a most spectacular fashion... Ugly Business.

I've seen a woman walk into the spinning propeller of the aircraft she just deplaned... even with someone standing there telling her to go the other way she wanted to thank the pilot who was coming around from the other side of the aircraft...

I scared the **** out of two girls at the gas station this winter. I look over at the next pump and both of them with long hair hanging and scarfs are in a running engine bay looking for where to add washer fluid. I yelled at them and they looked at me like I was nuts. Explained how they almost just had their hair ripped out or choked to death.

I was working on my drill press a couple days ago and bent down to look closer at the work.
The spinning chuck caught a few strands of my shoulder length hair.
As of today, I have a flat top that would make my USMC Daddy proud.

I remember the Yale incident pretty clearly. Couple of guys I know with New Haven Fire said it was a mess of a scene...

That specific Yale incident is why my local college- in Alaska- dropped their machine shop course.

That incident "put the fear of God", so to speak, in the administrations of colleges and universities nationwide- that's the kind of accident that can bankrupt a school if the family decides to get litigious.

We've all heard stories of schools- high schools and such- closing down wood shops and welding classes for fear of injury and the then-inevitable lawsuit? This was exactly that case.

In our case, there was an extenuating circumstance of the teacher of the machine shop course retiring, and his replacement bailing after one semester to go work on the North Slope, but the admin I spoke to said that was just the icing on the cake. The board was already looking to drop the class because of the Yale incident.

The class was cancelled in '12 or '13, and all the machines auctioned off that summer.

I've been training machinists for years and for the last three years, college engineering students. Ms. Dufault's tragic story is included in every safety lecture that I give and has been since I first learned about it.
The first line of my lecture is that the shop is the most dangerous lab in the building, that these machines are meant to cut, shape and form metal and will do the same to them, the machines don't know any difference.
I try to impress upon them that an accident that happens in a split second can affect them for the rest of their lives, or in the worst scenario, end their life.

I have a similar reminder on my left middle finger tip. Tore it off on a trailer tongue jack. Wasn't for a lack of PPE but I was in a rush due to breaking down in the middle of a city road and made a mistake. I have scar tissue in place of my finger print now.

I would phrase it like, you could be wrapped up in a lathe for the rest of your life. It would make them think, like what for the rest of my life? No way, oh wait you mean for the next 5 seconds till its over......

At my Nephews wedding his new bride walked out of the church and climbed into a convertible. She sat up above the rear seat with the "train" of her dress hanging down by the rear wheel of the car.

I hollered "Wait a minute", ran up, gathered up the train and handed it to her.. telling her it could easily get caught under the car, with horrific results.

She and my Nephew both looked at me like I was nuts.

Which may well... be but safety first....

Yeah, I have watched guys refuse to wear eye pro... I've seen guys refuse to use a respirator, I've fired guys for not wearing their PPE...

Things like that are one of the reasons my hair is well above my shoulders. A girl I know wears a wig because they couldn't reattach the chunk of her scalp where the drillpress at work pulled it off. She still wears her hair long and is still vain enough to wear it down at work. Something that has got her downgraded and reprimanded many times.

Real shame..

It cant be said enough to wear protective gear and be careful as much as possible. I will NEVER forget in high school using the bandsaw to cut out a guitar for someone, I managed to get just close enough for the saw to give my thumb a very minute paper cut before i yanked it back. I WILL NOT wear polyester when grinding things b/c it can catch fire, I will admit Ive done some stupid stuff before and have the stories and scars to prove it.

to note: I will NEVER forget my HS woodshop teacher-Mr. Wilson, AKA Woody. He showed us one hand..which all his fingers were the same size-due to the jointer. He asked for a lighter and showed us wtf happens when you stupidly decide to light up in the corner like an idiot (****-fire due to all the particulate saw dust!), he showed us what happens when the tablesaw can kick back and put a hole in reinforced glass of the back door.

-Isadora Duncan, a famous dancer back at the turn of the century, was killed that way- her scarf caught in the wheel, pulling her from the car and breaking her neck.

Yeah, I have watched guys refuse to wear eye pro... I've seen guys refuse to use a respirator, I've fired guys for not wearing their PPE...

-As apparently many here know, I'm a paintball guy. Been playing for many years, even owned a field for a while.

The primary piece of safety equipment is of course your goggles. We tell the players that as long as you keep your goggles on, the only thing a paintball can injure is your ego. :D

All the fields I've been to have been sticklers for goggle safety, but no matter how often we lecture, there will still be somebody- kid or adult, it doesn't matter- who will get hit, stand up, and lift their mask, and start walking out through continuing incoming fire.

Most- thankfully- only have to be yelled at once. Occasionally we'll yell at somebody a second time. If we have to tell them a third time, we ask them to leave. I've only had to do that once.

Doc.

The problem with this is that the few that end up with machinery in the home shop who dont work in industry never get any machine safety education unless they seek it out for themselves, which is more dangerous. Even when I was at secondary school in the late 90's to early 00's, we pretty much only were allowed to use drills, sanders and fret saws, of the stationery machines.

While getting my ME degree, I was a TA for my alma mater's machine shop classes. I used this same article when going over safety. I don't think I ever had to ask any of the girls to tie their hair up the entire semester.

Not a fatality - the kid is lucky.
What is REALLY stupid about this is the other guys around him that look like senior guys, did nothing about his baggy clothes. They should have kicked his *** with an iron boot before he could injure himself.

Many years ago worked in a punch press facility as a machine maintenance person. Can not remember how many times I had to rework or rewire the safety devices because the operator did not want to use all the safety guards. Many of them did not have ten digits and those that did they were not unscarred.

One of the reasons I always pitch a welding safety class is there are too many things a new welder does not know. Top one being lighters in the pocket.

Know a place with a 1/4x10 hydraulic shear that has been flood damaged (the GO pedal) and now all the safety switches the hand guard, the pedal, the front panel switch all of that will cause the shear to cycle. so you have to E-Stop it EVERY time you Move the sheet or it will chop whatever may be in there.

Brother cut halfway through 3 fingers on a table saw because he tripped on scrap underfoot.

I drilled a small hole in a finger that I used to back up a hand drill.

Worked in a plant with a guy with a missing hand. Makes you more careful!

Boss walked into work last week missing part of his thumb to the table saw.

Made me think 3x this weekend while using that and the chainsaw.

The other day I was telling another member (RJ) about my "little scare" I did here in the shop. I had my Makita grinder with a thick sanding disc on it and was sanding the sharp edges of a small metal triangle with my welding gloves on. It caught to my surprise the triangle and shot it into my stomach with enough force I thought I was impaled. I quickly raised my shirt expecting to see a gash and major blood flow. (I'm on blood thinners) . It just made a small cut but felt like I'd been hit with a 16 oz ball pen hammer....it's been a couple of weeks now and the wound is still there and itches like hell. Never again, like RJ said, clamp it in a vice, it takes longer, but is safer. When you get in a hurry you FU.
