Key Steps is SIL Callation During HAZOP

  • Identify safety functions and their required SIL based on dangerity.
  • Mengajak mereka seperti lihood of falure and potentiali akibatnya.
  • Evaluasi existing safety measts and their efektivenes.
  • Apa yang dibutuhkan untuk redudandansi repartasi yang diperlukan.
  • Dokument the rasionale for SIL ascment for each safety function.
