This study estimated stepladder accidents in 2006 at 3,896 (24 fatal accidents, 95%CI: 3,657–4,135), representing 2.9% (95%CI: 2.9–3.1) of all industrial accidents. The results indicate that individuals who fall from stepladders most frequently suffered from fracture (68.6%) or contusion (16.2%). Further, 65.5% of all the victims took more than a month’s leave of absence. The high severity of injuries of the victims of stepladder accidents indicates that there is a need for rapid disaster prevention planning. Further investigation of the working methods involving stepladders and their risk evaluation is necessary.
