Party fun turns tragic
A paintball gun's gas canister hits and kills a Cameron Park mom in a freak accident.

By Niesha Gates -- Bee Staff Writer
Published 2:15 a.m. PST Wednesday, February 18, 2004

Mark Contois was standing by his wife at their 10-year-old son's birthday party Monday when the freak paintball accident happened. Within seconds, Colette Contois, 37, was dead.

Authorities said she was killed instantly when a carbon dioxide canister inexplicably shot out from a paintball gun that a teen was taking apart.

"We were all breaking down the guns, and Colette was standing next to me, on my right," Mark Contois said. "Then I heard a bang, and her head fell on my shoulder."

Mark Contois, an El Dorado County social worker, gently placed his wife on the ground and checked for a pulse but found none. He prayed while administering CPR to no avail.

"I knew she was gone when her head was on my shoulder," he said Tuesday in his Cameron Park home.

El Dorado County sheriff's detectives ruled her death an accident, said Lt. Kevin House, spokesman for the Sheriff's Department.

The investigation revealed that when the paintball gun was being disassembled, a brass fitting on the carbon dioxide cartridge malfunctioned and didn't stay attached to the cartridge. Pressure from the gas turned the canister into a projectile, House said.

An autopsy is scheduled for today to determine a formal cause of death.

No charges will be filed against the 16-year-old boy whose paintball gun malfunctioned, House said.

According to her husband, Colette Contois loved throwing parties for family and friends and was looking forward to Monday's birthday celebration for her 10-year-old son Caleb and his best friend at the ROA Paintball game field near Placerville.

On Tuesday, counselors and psychologists were helping students and faculty members at Rescue School, where Colette was a speech therapist.

Sandee Barrett, principal of the kindergarten-through-grade-five elementary school, said Contois was a wonderful teacher who was adored by her students.

"She took a keen interest in her children and everyone else's children," Barrett said. "It's a tremendous loss to everyone, and it's very difficult to understand why someone so young and so vibrant could be gone."

At the family home in Cameron Park, family, friends and neighbors gathered to lend support to her children, Caleb and Leia, 12, and her husband, Mark.

"She had an awesome ability to bring people together," said Mark Contois. "She sincerely loved people and was very loved in return."

Sitting in a room filled with his wife's neatly organized scrapbooking supplies, Contois described what happened.

He said the party began with a prayer led by the paintball field's owner. "He prayed over the players and that we would all be safe and have a good time," Contois said.

Also playing on the field that day was a group of teenage boys who were showing the younger boys how to play and where to hide, Contois said. The playing stopped around 2 p.m., when both groups returned to the picnic tables to disassemble the paintball guns, which had been rented from the facility.

Bob McGuire, president of the American Paintball League and the Paintball Training Institute, said there is a test typically conducted on paintball guns, which are called "markers." The "valve twist test" is intended to keep accidents with the gas cartridges from occurring, he said.

"If the valve is not securely fastened, (the cartridge) could screw off from the valve instead of from the marker," McGuire said during a phone call from the training institute's Tennessee headquarters.

McGuire said paintball facilities are required to meet standards set by the American Society of Testing and Materials in order to qualify for insurance. However, he said, paintball facilities are not required to carry insurance, and the standards are voluntary otherwise.

McGuire also said he has not heard of other fatal accidents.

"It's a very unfortunate circumstance, but I don't see that it will change the procedures that are currently in place at paintball facilities," McGuire said.

Officials at ROA Paintball, which is a member of the Christian Paintball Players Association, declined to comment Tuesday.

Mark Contois said he is not contemplating filing a civil lawsuit. Rather, he said he would like to see a change in the way the paintball guns are dismantled, such as constructing barriers between people, so as to prevent other accidents from happening.

A memorial service will be held for Colette Contois at 10 a.m. Saturday at Green Valley Community Church, 3500 Missouri Flat Road, Placerville.
 
Ouch, sounds like the loctite didnt do its job and hold the valve in the tank. (at least I think the valve is screwed in there, with a lot of loctite to keep it from moving, but I could be wrong) :(

Wish they would have given the brand and model off of the canister. I'm wondering if its one of them newfangled large disposable tanks that screw into a valve, or one of the standard CO2 cans that has the brass fitting on the end and screws into the marker.

An unfortunate accident, but it will not dissuade me from playing.

I've had a canister start to unscrew from the valve like that on me before. Fortunately, I caught it before it got down more than a few threads. Unfortunately, the compressed gasses used are so common and safely used that people often forget that, in some cases, thousands of pounds of pressure are sitting attached to their marker. :(
 
something strikes me as odd when the fitting goes before the safety valve. I've had a few safety valves blow on me with full tanks and that was bad enough.
 
Yeah, it sounds to me that the pin valve unscrewed from the tank. I'd hate to be the guy who assembled that tank/valve setup. You know, there's a relief hole drilled into the valve's threads on the bottle side that should have prevented this from happening.

You mean those 3.5oz setups sold by "Gameface"? I don't think they have enough CO2 in them to cause this.
 
Sounded like a 12-gram to me. Those little 12 grams are right nasty, not that I've ever made rockets out of them or anything.
 
Freaky... a CO2 cylinder shoots off and, through some random, one-in-a-million chance, hits some poor woman in the head...

However, it's pretty stupid to disassemble a gassed-up marker.
 
Oh man...

We used those 12 gram CO2 canisters to make rocket cars in shop class freshman year. Those suckers were stuffed into the back of some poorly made light wood cars and then pierced. We shot these things down the hallway of the high school.

:uhoh:
 
Jeez...That is very sad news.

I don't think that was a 12 gram cartridge even though they used the term cartridge, only tanks have a brass fitting.
Here they state canister:
Authorities said she was killed instantly when a carbon dioxide canister inexplicably shot out from a paintball gun that a teen was taking apart.

Every time I break down My paintball GUN(Marker is a recent term), I've always looked for that very problem. I always had the tank's valve pointing upwards while screwed in to the Gun to reduce risk, and possible damage from CO2 going liquid on Me. Have to be careful of those HPA tanks too.
Besides a valve/threading failure, sounds like the teen was holding it by the side of the tank instead of the bottom of it while unscrewing.


You know, there's a relief hole drilled into the valve's threads on the bottle side that should have prevented this from happening.

The safety valve/nut would'nt have helped in this case. Since the bottle was already unscrewed that much from the valve, the tank flew like a rocket.
Those valve safeties only work when there is too mush pressure build-up in the tank due to overfilling and a rapid rise in tank temp., then the burst disk goes and vents through the safety valve hole.
 
Some sort of thread failure at the valve maybe? With or without Loctite the pressure in the cylinder be exerted against the valve and therefore the threads should have kept the valve in place. Try charging an SCBA, or a SCUBA tank sometime then try getting the connection off; ain't happenin'.
I gassed myself a couple of times, and I saw someone get whacked when his remote broke loose once, but never seen a tank launch. Bummer for all involved.
It never occurred to me before that a tank could break loose, and that's after playing casually for 6 years.......
 
The safety valve/nut would'nt have helped in this case.
Not talking about the burst disc on the upper portion of the valve (had two of those blow on Saturday). There is a hole drilled about half way down the threads onto which the bottle threads and is intended to prevent this exact thing. Check the image:

The bad side to the loctite is that it will often plug that hole. I always clean the vent before (re)installing on a the bottle.

I've had more than one rental tank begin to unscrew from the valve while fully pressurized. It's scary to think about the possibilities...

I did'nt initally see that You said "bottle side", My mistake. But I have to add, there have too many times I have seen valves that did'nt have that hole. This might have been one of those cases.
It's also true about the locktite plugging the holes when present. Sometimes metal shavings and locktite.
Side note: The industry really has to get up to speed with this kind of stuff. I had one of the tanks(from a well-known maker) that did'nt have the hole drilled into the nut. Got a free replacement.

Paintball gun accident kills mom at son's birthday party

Associated Press


CAMERON PARK, Calif. - Memorial services are scheduled Saturday for a 37-year-old woman killed when a carbon dioxide canister exploded out of a paintball gun being disassembled during her 10-year-old son's birthday party.

Colette Contois, an elementary school speech therapist and mother of two, died instantly Monday when struck by the canister, authorities said.

"We were all breaking down the guns, and Colette was standing next to me, on my right. Then I heard a bang, and her head fell on my shoulder," said the woman's husband, Mark Contois.

The El Dorado County Sheriff's Department ruled the death an accident.

Sheriff's Lt. Kevin House said an investigation determined a brass fitting on the carbon dioxide cartridge malfunctioned and came loose while a 16-year-old boy was disassembling the gun. He said pressure from the gas turned the canister into a projectile. House said no charges will be filed against the 16-year-old.

Officials at ROA Paintball near Placerville, a member of the Christian Paintball Players Association, declined comment. Bob McGuire, president of the Tennessee-based American Paintball League and Paintball Training Institute, said he has not heard of other fatalities.
 
Not that I'm calling anyone a liar, but I have never heard of this happening with paintball canisters. Kinda odd considering that these canisters are made to be attached to the paintball gun and roughed up during games. I'll have to keep this in mind when I break down my paintball gun.
 
From what I have heard, the kid wasn't paying attention, and unscrewed the valve from the tank (turning it into a rocket).
 
He's lookin' for a lawyer as we read... No way this wasn't the fault of the kid doing the dis-assembly. Of course that won't matter to a kali jury and the kids lying lawyer. :banghead: :fire:
 
Marker is a recent term

It's not a recent term, it's the proper term, and I encourage its use. It's a cool word.

I have seen one tank start to unscrew from the valve, I let it leak itself off before reassembling it. It really shouldn't happen if this stuff is properly worked on. Or if someone unscrewing the tank has enough sense to realize what is happening unstead of just keep twisting when it doesn't come off. I would hope a 16 year old would know better if that's actually what happened.
 
Very sad freak accident. If it was the brass pin-valve then a lot of things had to go wrong, as noted by others.

I used to own and run indoor & outdoor fields and we NEVER saw this one happen. Usually the pin valves are very hard to remove but I can imagine it happening if the relief hole was blocked or it didn't have one (smells like a lawsuit in that case).

Thread failure is also possible. Threads might have been damaged by prior 'maintenance.'

I have seen TWO of the large 80L liquid cylinders fall over and have the valves knocked off (improperly mounted, not chained in place) -- both of them turned into 100+ lb projectiles but nobody got hurt both times (lucky).
