Step 5 SIS Installation, Commissioning, Validation

Safety lifecycle phase or activity Objectives Requirements Clause or Subclause of ISA-84.01-2004 Inputs Outputs 

The SIS installation began with the availability of design, building facility, process equipment, utilities (e.g., electrical) and instrumentation equipment. The installation ended with the transition (i.e., turnover) of the SIS from Construction to Operations. This transition reflected acceptance by Operations at this time Commissioning was begun (see clause 5.5.2 below). 

The corporate purchasing and receiving inspection functions were considered adequate to ensure that the specified SIS components were received in good working order, with appropriate documentation to support their use per Clause 11.5 of ISA-84.01-2004. Interim storage adheres to the manufacturer s safety manual for each device and includes any necessary preventative maintenance for the equipment. 

Note that a procedure was available to transition back to Installation mode so that corrections to problems found by Operations could be implemented this transitioning resulted in adjacent equipment being in different states of completion/acceptance (i.e.. Installation versus Operations state). For this project a white tag was used for Operations state and a green tag for Construction state. 

Each instrument was identified with its instrument tag number. The SIS was provided with the following additional identifying characteristics
