Preventing falls from height

墜落・転落の防止

Learn the rules for not falling from high places and how to use fall-arrest equipment.

Key points

  1. In the construction industry, 214 people died in work accidents in 2025. Of these, 91 died in accidents of falling from a high place. This is the most common kind of accident.

    建設業では、2025年に214人が仕事の事故で亡くなりました。そのうち91人は、高い場所から落ちる事故(墜落・転落)でした。一番多い事故です。

  2. In places 2 meters or more high where there is a danger of falling, the company must provide a work platform (a floor to stand on and work), handrails, enclosures, covers, and so on. Do not remove handrails or covers over holes without permission. If you find one that is off, do not go near it, and tell the foreman (shokucho) at once.

    落ちる危険がある高さ2メートル以上の場所では、会社は作業床(立って作業をする床)や手すり、囲い、覆いなどをつくらなければなりません。手すりや穴の覆いを、勝手に外しません。外れているのを見つけたら、近づかないで、すぐに職長に知らせます。

  3. Fall-arrest equipment (tsuiraku seishi-yo kigu) is equipment that stops your body when you fall. If you are told to use it, always use it (this is a national rule). Every time you move, attach the hook to the strong place that has been decided.

    墜落制止用器具は、落ちたときに体を止める道具です。使うように言われたら、必ず使います(国の決まりです)。フックは、移動するたびに毎回、決められた丈夫な所にかけます。

  4. Before use, check the belt and rope for damage and check that the hook moves properly. Do not use equipment that has damage or that has taken the force of a fall even once. Tell the foreman and replace it.

    使う前に、ベルトやロープの傷と、フックの動きを点検します。傷があるものや、一度でも落ちたときの力がかかったものは使いません。職長に知らせて、取りかえます。

  5. As a rule, fall-arrest equipment is the full-harness type (a type that also has belts on the shoulders and legs). Work that uses the full-harness type in a place 2 meters or more high where a work platform cannot be provided may be done only by people who have received special education (tokubetsu kyoiku). This material does not take the place of special education.

    墜落制止用器具は、フルハーネス型(肩や足にもベルトがある形)が原則です。作業床をつくれない高さ2メートル以上の場所でフルハーネス型を使う作業は、特別教育を受けた人だけができます。この教材は、特別教育の代わりにはなりません。
