Violation

On June 13, 2024, in Itabashi Ward, Tokyo, during air conditioner replacement work at a private residence, Worker B of Corporation A, along with two workers from the prime contractor Corporation Frontier Express, was working on the exterior wall of the residence. They had set up a five-meter ladder, climbed it, and were cutting the piping of an air conditioner at a height of 5.4 meters when they fell from the ladder. As a result, they sustained skull fracture, brain contusion, spinal injury, and experienced consciousness disturbance and paralysis of limbs. Consequently, Corporation Frontier Express was sentenced to a fine of 200,000 yen by the Tokyo Summary Court under Article 21, Paragraph 2 of the Industrial Safety and Health Act, with the judgment finalized on December 12, 2025. This constitutes a violation of Article 28, Paragraph 1, Item 3 of the Construction Business Act.
