Safety Tips span Materials handling Handling and storing compressed gas cylinders Mishandling compressed gas cylinders – which can have internal pressure of up to 2,500 pounds per square inch – can be disastrous. Dropping, tipping over or exposing a cylinder to heat can cause weaknesses or cracks in the cylinder’s shell, which can result in a shrapnel-laden explosion, according to the American Welding Society. When storing compressed cylinders, AWS recommends: Secure cylinders upright with a chain or strap in a proper cylinder cart. Store cylinders at least 20 feet from combustible materials in a dry, ventilated place. Keep oxygen cylinders at least 20 feet from fuel gas cylinders. Ensure valves are completely closed and any protection devices are secured. Avoid storing cylinders in lockers – a leak could result in a dangerous gas buildup. Use proper warning signs in areas where cylinders are stored. Keep cylinders in a location free from vehicle traffic, excessive heat and electrical circuits.

Keep empty cylinders away from full ones. The majority of incidents and injuries involving gas cylinders occur during handling or transportation, AWS states. To help prevent incidents when moving cylinders, AWS offers the following tips: Handle cylinders with care and avoid dropping or hitting them against anything. Follow proper procedures and use the right equipment, including safety glasses, heavy-duty gloves and protective footwear. Ensure safety measures, such as caps or guards, are securely installed. Use a cart or hand truck instead of dragging or rolling cylinders. Use proper cradles, nets or platforms if using a crane. Avoid lifting cylinders by their caps or guards or with magnets or slings, which can damage the valves.A fourteen-year old boy in China was killed when a chair he was sitting in exploded. Chunks of metal pierced the boy’s rectum resulting in extensive and fatal bleeding. This is not the first time such a thing has happened, but it is the first fatality.

The boy was alone when the accident occurred, sitting on his computer chair. Bravely, he managed to make one last phone call to his father despite being in horrific pain. An ambulance was immediately summoned, but it took an hour to get him to the hospital and he died enroute. The “killer chair” was a common gas-cylinder-based chair the height of which can be altered via a cylinder located at the base of the chair, which contains highly pressurized gas. Allegedly, energy created by the seat cushion caused the explosion.waiting room chairs nsw The fact that three similar incidents were reported at a hospital in the last month alone, suggests an influx of malfunctioning chairs. chaise lounge chair crate and barrelBack in 2007, such a chair propelled a metal part into the rear of a 68-year-old man, who suffered a severe wound but survived.best place to buy herman miller aeron chairs

In all of the incidents three factors were implicated: • Non-nitrogenous gases contaminated the cylinder of the chair. • Deficient materials in the cylinder reduced the durability of the part. • The cylinder was not completely airtight. Although oil-based hydraulic devices are said to be safer, most such chairs on the market today use gas cylinders and the majority of them come from China.

In 1969, an entertaining tale of an errant cylinder was published in a pharmaceutical company’s internal newsletter. According to the story, a bunch of painters took six 220-cubic foot gas cylinders off their off their wall supports and put them to the side to allow the painting of an area. A painter, who was trying to scoot one of the cylinder across the floor, realized that it was leaking gas. But before he could do anything, he found himself being jet-propelled across the construction site. The amusing story has spread through safety circles and the academic literature, appearing in the Journal of Chemical Education , which is published by the American Chemical Society, in  June 1976. But does the account contain any element of truth? It turns out that’s quite unclear. One man — David Gervais, who is part of the Science Teachers Association of Ontario in Canada — has been on a mission to get records cleared up since September 2014. Gervais found the tale in the archival records of his own safety organization’s magazine two years ago, and was immediately suspicious since it read like a “comedy of errors.”

Here’s the next part of the tale (under a different title) from the Oklahoma State University’s website: The man suddenly found himself with a jet-propelled 215 pound piece of steel. He wrestled it to the floor, but was unable to hold it. The cylinder scooted across the floor hitting another cylinder, knocking it over and bending its valve. The cylinder then turned 90 degrees to the right and traveled 20 feet where it struck a painters scaffold causing a painter to fall 7 feet to the floor. After spinning around several times, it traveled back to its approximate starting point, where it struck a wall. At this point, the cylinder turned 90 degrees to the left and took off lengthwise of the room chasing an electrician in front of it. It crashed into the end wall 40 feet away breaking four concrete blocks. It turned again 90 degrees to the right, scooted through a door opening, still chasing the electrician. The electrician ducked into the next door opening, but the cylinder continued its travel in a straight line for another 60 feet, where it fell into a truck well striking the truck well door.

The balance of the cylinder pressure was released as the cylinder spun harmlessly around in the truck well area. The painter who fell from the scaffold received multiple fractures of his leg. It goes on to read: This incident illustrates what can happen when a valve is separated from a compressed gas cylinder. The one contained pressure of about 900 pounds per square inch, but many cylinders are pressurized to 2200 pounds per square inch. If you have any doubts about the need for anchoring compressed gas cylinders, you might think about the 2200 pounds per square inch and ask yourself, “what if….?” In preventing the accidental release of compressed gases, all precautions must be taken to avoid dropping, knocking over, rolling or dragging cylinders as well as striking cylinders against each other. This means that it is imperative that all cylinders be stabilized in storage, transportation, and in use. Gervais said he thought the story he thought the story was “unbelievable,” but he was surprised to see the article made its way into a credible academic journal like the Journal of Chemical Education as well as university websites and other safety protocols.

The tale was mostly retold as a true story with no disclaimers about its origins such as by the US Department of Agriculture or by Canada’s National Lifeguard Service (which gives it the title “Cylinder Hazard — A True Story”), Gervais noted. The Oklahoma State University site, however, did post  a disclaimer (although we’re not sure when) , which reads: The following account of a wayward gas cylinder was found about 20 years ago in an old newsletter from a safety organization. The story was already several years old. The organization has asked that it not be attributed to them because they don’t know/can’t find the original account and don’t remember where this actually took place. Nevertheless, it is still a good example of the forcefulness of a compressed gas cylinder and why it is important to handle one with caution. Gervais continued his hunt for the story’s history, and found that it was previously published in a newsletter published in New York.

Eventually, said Gervais, he was informed that the article originated from an internal newsletter published in 1969 by the pharmaceutical giant  . Ultimately, Gervais’ aim is just to solve the mystery of where the tale of the errant cylinder started, as he told officials at the pharmaceutical company: did they want a mystery solved? Much to his disappointment, however, Gervais has yet to track down the original authors, since the article was published so long ago. He told us his committee got the tale from the Journal of Chemical Education. The journal, he said, got it from a safety newsletter in New York, who in turn got it from Eli Lilly and Co. According to Gervais, along the trail, someone suggested that the original tale came from the University of Oklahoma, but no one has been able to verify its veracity. Gervais’ guess is that safety newsletters and academic journals at the time wanted to use comedy as a literary tool. Here’s another outlandish one that Gervais sent us from around the same time period:

One of them involved a man and woman intimately involved except the dripping of a kitchen tap interfered with the moment. In his bathrobe he attempted to fix the tap leaving his posterior exposed to the air. A passing cat scratched the exposed butt, causing the plumber to hit his head, knocking himself out. Hearing the noise, she found her husband and called the ambulance. On the stretcher, the husband recalled the events to the ambulance personnel. Laughing so hard they dropped the plumber, breaking his arm. At their worst, such myths in scholarly literature can not only confuse people, but also mislead them, said Gervais. Educational safety officers, for example, …will go through our journals and take a look at articles like that. Next thing you know, they’ve got a ban on gas cylinders. Although Gervais has never asked anyone to retract the article, we’ve contacted the editor-in-chief of the Journal of Chemical Education to ask if the journal has any intentions of pulling the article.

As of yet, we haven’t heard back. It’s easy for Gervais to see how untruthful accounts can accumulate. Gervais’ science teachers committee, which has around 4,000 members, published an online journal — (which is now a blog) — about hazardous incidents, like gas leaks, that took place in schools. They called the feature “learning by accident.” But, Gervais added, because such incidents were so rare, the journal began to run out of content. So, contributors came up with a solution: they started making up the scenarios. When Gervais became the chair of the organization, however, he began to make sure all the magazine’s content was truthful — as learning by accident implies. And now, Gervais is conducting the daunting task of going through decades of the magazine’s archives and retracting articles that he knows to be fictitious; so far, he has removed six or seven articles from the Crucible site. As for the tale of the errant cylinder, this is still on the Crucible site, but with a disclaimer about its authenticity, said Gervais.
