Poisonous Office Chair

The 'poisonous office chair' mainly has issues such as excessive formaldehyde levels, the use of 'shoddy scrap materials,' and explosion risks.

Excessive Formaldehyde Levels: The problem of formaldehyde release in office chairs primarily stems from their manufacturing materials, including fabrics, fillers, and artificial boards. If these materials are of poor quality, they can lead to excessive formaldehyde emissions. Prolonged exposure to an environment with excessive formaldehyde can have severe impacts on human health. Contact with low concentrations of formaldehyde may cause symptoms such as dizziness and fatigue, while high concentrations are highly irritating and can be toxic to the nervous system, immune system, and liver, potentially even causing cancer.

Use of 'Shoddy Scrap Materials': Some unscrupulous merchants, in an attempt to reduce costs, use 'shoddy scrap materials' to make office chairs. These materials are often of inferior quality and may contain harmful substances, posing a threat to human health. For example, a man who purchased an office chair online experienced discomfort after prolonged use and eventually discovered that the interior of the chair was filled with 'shoddy scrap materials'.

Explosion Risks: Some substandard office chairs pose explosion risks, primarily due to the use of inferior gas springs. Thin walls of the gas spring, impure inert gases, or even the use of compressed air instead of inert gases can lead to explosions. Additionally, excessive heat generated by repeated and frequent lifting and lowering of the seat during use can also trigger an explosion. If a blast-proof steel plate is not installed and corners are cut, the explosion risk is further increased. There have been multiple incidents of office chair explosions in history, resulting in casualties and property damage. For instance, in 2017, an office chair belonging to a colleague of a netizen in Anhui exploded, damaging the computer's main case; in 2009, a 14-year-old boy in Jiaozhou, Shandong, died due to an explosion of a swivel chair at home; in 2010, Ms. Liu suffered severe injuries to her buttocks and abdomen when a swivel chair suddenly exploded while she was sitting and blow-drying her hair.
