In other words, in the process of designing and constructing buildings such as apartments or buildings, AD (Air Duct), PS (Pipe Space) and EPS (Electric Openings such as pipe spaces and dust spaces should be considered.

Accordingly, the worker covers the openings with the boards and the like, and the boards covering the openings are easily detached from the home position, so that there is always a risk of the worker falling into the openings. It could not be tolerated and damaged, causing workers to be injured.

These openings are inevitably open during construction, but are closed only after the interior and exterior are completed in the final stage of construction and are not revealed when the construction is completed.

However, when such openings remain open at construction sites that are usually very dark due to insufficient lighting during construction, construction workers may fall or construction materials may fall through the openings. In this case, the risk of falling and falling is very high because the location of the opening is connected to the same place from the height to the height of each floor.

On the other hand, since these openings are also used as transport passages for construction materials between floors in the construction process, they cannot be completely covered until the closing of the openings.
