Abstract A large number of events which workers have death when working on the construction are happened when fabricating or dismantling the inclined hedge, spreading decks fully and falling from the deck edge. The workers fall down easily when fabricating or dismantling the major connective horizontal bar of inclined hedge because the strength of the bar is not enough, the inclined hedge support bar is old, open the lock on the safety belt when moving, or influenced by wind-force. This research, in order to avoid the danger of the inclined hedge while fabricating or dismantling, will be investigated the reason of the setting up the inclined hedge and the substitutable method the of the inclined hedge to enhance the safety function. After that the equipments and laws can be matched perfectly to protect the safety of the worker and decrease the working events. The main research results include that do the inclined hedge’s rule collection and complete the strength test of bars which are the main structure of the inclined hedge; do the impacting test by changing the potential energy to kinetic energy to examine the situation of receiving loads on each bar of the inclined hedge, and finish the test for fabric sheets to create the standard regulation by throwing heavy thing to the surface of the net and pulling it. According to the test result, try to build the standard for structure, function and strength to make reference to each company.
