    Abstract: It is a reality that subcontracting for the completion of work is becoming globalized and the risk of
such work is being outsourced. In this study, we tried to secure the safety of the air conditioner worker through
structural examination of the protection area (equipment with a safety bar) which is a representative example
of domestic outsourcing. However, there is no proper protective standard that can work safely during the
installation and repair process of air conditioners in Korea and there is no obligatory safety check before the
product is released. Equipment with safety bars was judged according to the performance standards presented
in preparation for falls and safety verification was determined by simple structural analysis rather than
complicated numerical simulation. In order to more easily obtain products that satisfy the safety performance
criteria, a proper cross-section was calculated and tested through experimentation with change of load and
deflection rather than through repetitive fabrication.
