Level of safety and risk petrochemical process industry must be guaranteed. Instrument as a safeguard should be able to guide and provide protection against worker safety, environmental and corporate assets. So that the necessary hazard studies and risk management assessment of the plant that has been operating in a relatively long period. PKG industry is one of the largest fertilizer producer in Indonesia supported the important equipment and need serious attention. Boilers are at risk and danger equipment relatively high. So it is necessary to study. Danger level measurements performed with HAZOP studies with determination nodes consisting of; economizer, steam drum, superheated, and burner system which is the main constituent components of the boiler By evaluating the systems supporting documents consisting of Process Flow Diagram (PFD), P & ID and historical maintenance data for the period scheduling. That components having the highest risk of harm is Pressure Indicator Inlet steam drum, Temperature Indicator (TI-6211) and Temperature Superheated Outlet Indicator (IT-6214), with the level of risk is worth 5 (extreme) refers to the standard AS/NZS 4360: 2004. Each of the other nodes in the boiler has a SIL 1, with a risk reduction factor= 50 for economizer, steam drums= 39.1 and superheated and burner system= 30. Based on the value of the boiler system has a relatively low reliability level indication. Decrease risk and increase system reliability is done with care and instrument calibration routine, the increase of redundant instruments (sensors, transmitters, controllers and final control elements) should be maintained strictlyÂ …
