Description

  The present invention relates to a fallen object prevention tool for preventing fallen objects falling during work at a high place.

  In a room that is already in operation and in use, such as an office building, a computer room, or a server center, a refurbishment work is often performed while leaving the equipment and furniture used by the user as is. As building equipment, there are many equipment and parts installed on the ceiling, such as lighting fixtures, air-conditioning vents, various sensors, fire-fighting equipment terminals, and equipment installed in the ceiling. Ceiling works are high-altitude work and upward work due to their nature, and the attitude of an unstable worker with very poor workability is forced. In such refurbishment work, the installation equipment itself, parts such as bolts and nuts, tools, work scraps, etc. may fall during work in places where work is conventionally performed at high places. In order to protect these devices and fixtures, curing is performed by applying a protective net or a curing sheet (see, for example, Patent Document 1).

  For example, as shown in FIG. 4, when the worker P1 installs the alarm device 52 or the like on the ceiling 51 in the equipment room where the communication equipment 50 or the like is installed, some fall such as the installed equipment main body or work waste In order to protect the communication equipment 50 and the like from the object 53, the antistatic sheet 54 and the like are put on the communication equipment 50 before the installation work.
