                                 good engineering practice and standards are to be employed in any
                                 control system(s) fitted.
                              
                              
                              
                            
                           
                           
                           
                              
                              
                              12.1.2 Due
                                 to the wide variety of types of process plant, it is not possible
                                 to lay down precise details of control scheme(s), since any control
                                 scheme is affected by the nature of, and the operating procedures
                                 of, the process plant. A description of the expected method of operation
                                 of the process plant is to be submitted.
