Determining the system to work at heights should take into account several things. There are several systems or ways of working at heights, namely:

1. Passive System, namely a system where when working through a permanent structure or a non-permanent structure, it does not require the use of fall protection devices because there is already a collective protection system. This system requires basic supervision and training. Work method:
   a. Works on surfaces such as bedroom floors, balconies and paths;
   b. Permanently installed structures/work areas (platforms) and equipment;
   c. Working in a space with an open window of its size and configuration can protect people from falling.
2. Active System, That is a system in which there are workers who go up and down (lifting/lowering), or move places (traverse) using equipment to access or reach a work point because there is no collective protection system. This system requires good supervision, training and operational services. Work Method:
   a. Permanently installed building maintenance units, such as gondolas.
   b. Scaffolding (scaffolding).
   c. Structure/work area (platform) for climbing such as stairs on a tower.
   d. Elevating work platforms/structures such as hoist cranes, lift cranes, scaffolding cars.
   e. Temporary structures such as stage performances.
   f. Ladder move (portable ladder)
   g. Rope access system
3. Rope Access System (Occupational Rope Access), ie Rope Access can be classified as an active system. Rope access is a technique of working using rigging and various equipment and with special techniques. This method is usually used to achieve difficult-to-reach job positions according to various types of needs. This system prioritizes the use of personal protective equipment as movement restraints and work restraints and administrative control in the form of supervision and work competence for its workers. The prerequisites for using a rope access system are:
   a. There is a work line (working line) and a safety line (safety line)
   b. There are two fasteners (anchorage)
   c. Tools and personal protective equipment
   d. There are competent personnel.
   e. Strict supervision.
   Examples of rope access applications such as:
   1). Work up and down on several sides of the building (facade), atria of buildings, towers (towers), bridges and many other structures;
   2). Work at horizontal heights such as on bridges, roofs of buildings and others;
   3). Work in confined spaces such as vessels, silos and so on.
   4). Tree climbing work, rock climbing, caves, out bound and so on.

Rope access techniques are reliable and tend to be effective for performing inspections on installation systems and some light to moderate jobs. The rope access method is an alternative way to complete light to moderate work in difficult positions and which require rapid task force.
