You may have heard some news about an office chair gas cylinder explosion. There is no doubt that all the explosions in the seat are caused by the gas cylinder. Why height adjustable office chairs explode the reason is caused by bad quality gas cylinders, not by the qualified gas cylinder. So how do we judge whether the height-adjustable office chairs we have used in the office are safe? I have many basic methods here to select the qualified office chairs or computer chairs, please keep in mind.
1. 3 tips to judge your office chairs explode or not
1) Verify the steel markings to ensure they meet the qualification standards.
A gas cylinder is also known as a gas lift or gas spring.
Regularly office chair gas cylinder manufacturers produce qualified gas cylinders which will be marked with the trademark and qualification information. If the gas cylinder does not have any qualification steel markings, then DO NOT buy it. This kind of office chairs explode at any time.
SAMHONGSA gas cylinder, the abbreviation on the cylinder is “SHS”, and the edge of the cylinder is printed with “SAMHONGSA”, Established in 1970, SAMHONGSA CO., LTD., SHS gas cylinder has passed the world’s eight certifications ( Such as BIMFA, LGA, TUV, SGS, etc.), even the steel tube is 3.5mm thickness, do not have to worry about the danger of office chairs explode. Some of the office chairs, such as Okamura chairs in Japan use the SHS gas cylinder. Melody’s office chair uses a BIMFA-tested gas cylinder, this would make sure office chairs won’t explode.
KGS gas cylinder, the abbreviation for “KGS”, the full name “Korea Gas Spring”, is also a well-known Korean company, its gas cylinder products have passed ISO9001, ANSI, BIFMA, DIN, UN, and other certifications. Some of the computer chairs use KGS gas cylinders. That also protects you and office chairs won’t explode.
XieQiang gas cylinder: the cylinder is stamped with “XIE QIANG” letters, produced by Guangdong Yueqing Gas Spring Manufacturing Co., L TD. It has passed ISO9001, BIFMA 5.1, TUV, and other certifications. Finland Salli brand saddle chairs use Xieqiang gas cylinders.
Besides the trademark on the cylinder, the gas cylinder’s manufacturer also prints certification information, which aids in assessing the cylinder’s quality. These certifications include domestic, international, and those from various developed countries, offering a broad range.
For instance, ISO9001 is an international quality certification system, BIFMA is the certification from the American Furniture Association, ANSI is the American National Standards Institute certification, TUV is the German mark for component product safety, LGA is the certification from the German technical supervision unit, DIN represents German industrial standards, EN stands for European standards, and SGS is a standard technical certification.
2) Listen to the sound to identify the material
The safety of a gas cylinder is ensured by the quality of the materials used. The test pressure of a gas cylinder can reach up to 2.43 MPa, which is powerful enough to penetrate at least six high-density boards. If the cylinder is made from inferior materials, it naturally cannot withstand such high pressure, increasing the risk of explosion.
So how can we judge the material of the cylinder body? We use metal objects to knock the cylinder rod, the sound is crisp, is made of steel, and it’s safer. If the sound is muffled, and the cylinder is electroplated iron, the danger is relatively high.
3) Smooth motion when you adjust the height
A certified gas cylinder is filled with an inert gas, such as nitrogen, which ensures that even in the event of an explosion, it will not ignite or burn.
So, why the office chair shown in the experiment video was burnt?
The reason is the high cost of nitrogen, so some unscrupulous businessmen use compressed air instead of nitrogen to fill the gas cylinder. We know that compressed air contains oxygen when the air and lubricants are mixed in a high-pressure environment. Once they mix together it will occur chemical reaction – explosion and combustion.
So, how do we judge whether the gas cylinder is filled with air or nitrogen?
It is very simple to judge. Inert gas is not able to burn and also has a good lubricating effect. So the gas cylinder filled with nitrogen is very smooth when moving, non-stuck in the process of rising and falling.
However, compressed air is a mixture of gases, lubrication ability is poor, and the gas cylinder filled with air in the process of rising and falling will have an obvious fast or slow and jarring feeling.
2. Do you want office chairs explode? Add more 4 methods to ensure safety
If you are considering buying a gaming chair or office chair from the Internet or local market, or you are not sure about the safety of a chair used at home or in the office, then I will provide you with four methods to ensure your personal safety. However, no one wants office chairs explode, right?
1) Do NOT be greedy for cheap, unless you want office chairs exploded
The cost of a good gas cylinder is relatively high, so the overall retail price of the height adjustable chair should be more than USD100, this makes sure manufacturers and businessmen have a reasonable profit. If the chair price is less than USD40, then it is very likely that the gas cylinder is bad and dangerous. To buy these height adjustable chairs is like holding a “random bomb” at home or office, extremely dangerous.
2) Check out the brand, refuse to three “No” products
If you do not know anything about furniture selection, then the easiest way is to select well-known furniture brands such as Steelcase, Herman Miller, Okamura, Salli, and other China furniture brands, Such as Melody, Sitzone, UE, etc, the quality is guaranteed.
If you look at the chair is No production date, No quality certificate, No manufacturer name of the “three no” products”, absolutely do NOT buy, unless you want your office chairs explode under your butt.
3) Select the explosion-proof of height adjustable office chairs
The possibility of office chairs explosion in extreme cases still exists, even if the gas cylinder is manufactured by a regular qualified supplier, but also in case of an explosion.
To ensure personal safety, the most effective way is to add a whole explosion-proof steel plate between the cylinder and the seat, this would protect you from less harm when office chairs explode, usually 3.5-4 mm thickness, used to resist the impact of an accidental explosion, the thicker the steel plate used, the safer chair we get.
When choosing height-adjustable office chairs, ensure you select a brand that includes an explosion-proof steel plate and that the thickness of the steel plate meets the necessary standards.
4) To replace the old office chairs, in case of office chairs explode
Mechanical parts have a service life; over time, the components of a gas cylinder will age. The rubber seal may deteriorate, the metal may fatigue and develop cracks, and aging seats can become safety hazards. If your office chair isn’t a high-end model worth hundreds of dollars, it’s generally recommended to replace it after more than 5 years. Although the likelihood of a quality office chair failing after 3 years is very low, replacing the old one with a new one remains the safest and most secure method.
3. Consider qualified office chairs manufacturer since now
When it comes to furnishing an office, whether for a small business or a large corporate tender project, the quality and safety of office chairs are paramount. Not only do they need to be comfortable for long hours of use, but they also need to meet safety standards to prevent accidents, such as the office chairs explode.
Quality office chairs are designed with ergonomics in mind to provide proper support to the back, neck, and legs, reducing the risk of work-related injuries. They are also built with high-quality materials that ensure durability and longevity, making them a wise investment for any business.
Safety is another critical aspect of office chairs. Reputable manufacturers adhere to strict safety regulations during the design and production process. These chairs are tested for stability, load capacity, and material safety to prevent any incidents that could lead to injury or damage.
For businesses looking to purchase office chairs wholesale or for a tender project, it’s crucial to partner with a supplier that prioritizes both quality and safety. A reliable supplier will offer chairs that are not only ergonomically designed but also certified for safety, giving peace of mind to both the purchaser and the end-users.
In conclusion, selecting the right office chairs is not just about aesthetics and comfort; it’s about ensuring that every person who uses them is seated safely and securely.
