ISA-TR84.00.05 is strictly informative and does not contain any mandatory requirements.

ISA-TR84.00.05 is intended to be used by those with an understanding of the basic requirements of ANSI/ISA-84.00.01-2004 and other good engineering practices applicable to BMS (references 4.4 to 4.8).

ISA-TR84.00.05 is intended to be used in conjunction with other good engineering practices. This technical report is not intended to stand alone or be a replacement for BMS-specific practices.

This technical report is intended to:

a) Identify and classify SIFs within typical BMSs for typical operating modes of fired equipment (e.g., pre-firing, light-off, shutdown, and normal operation);

b) Provide examples of typical safety assessments for the following equipment with BMSs: boilers (single burner), fired process heaters (multi-burner), thermal oxidizers, oil heater treaters and glycol reboilers.
