The National Institute of Technology and Evaluation (NITE) in Japan has documented 310 accidents related to secondhand products over the five-year period ending in 2024. Approximately 90% of these accidents involved fires, with about 30% linked to products containing lithium-ion batteries.
Common items included bicycles, air conditioners, kerosene heaters, and fan heaters. NITE noted that the increase in such accidents coincides with greater use of flea market apps amid consumer inflation. The institute received reports of these incidents, which highlight risks from defects, recalls, and product degradation.
One incident involved a battery for a power tool purchased through an online auction in Aichi Prefecture. The battery, from a third-party company, exploded while in storage after charging due to a defective safety mechanism. In another case, a dehumidifier obtained from an acquaintance caught fire after it was identified as a recalled product.
A separate fire resulted from age-related deterioration in an air conditioner that remained installed in a previously owned home. These examples demonstrate potential hazards in secondhand items, including explosions and fires.
NITE recommends that consumers verify the usage history, defects, and recall information for secondhand products before acquisition. The institute stated that possessing the instruction manual is essential for proper usage. If a product operates unstably, users should discontinue its use immediately to avoid accidents.
