(D) Safe upper and lower limits for such items as temperatures, pressures,

flows or compositions; and,

(E) An evaluation of the consequences of deviations, including those

affecting the safety and health of employees.

(ii) Where the original technical information no longer exists, such information

may be developed in conjunction with the process hazard analysis in

sufficient detail to support the analysis.

(3) Information pertaining to the equipment in the process.

(i) Information pertaining to the equipment in the process shall include:

(A) Materials of construction;

(B) Piping and instrument diagrams (P&ID's);

(D) Relief system design and design basis;

(E) Ventilation system design;

(F) Design codes and standards employed;

(G) Material and energy balances for processes; and

(H) Safety systems (e.g. interlocks, detection or suppression

systems).

(ii) The employer shall document that equipment complies with recognized and

generally accepted good engineering practices.

(iii) For existing equipment designed and constructed in accordance with

codes, standards, or practices that are no longer in general use, the

employer shall determine and document that the equipment is designed,

maintained, inspected, tested, and operating in a safe manner.

(e) Process Hazard Analysis.

(1) The employer shall perform an initial process hazard analysis (hazard

evaluation) on processes covered by this standard. The process hazard

analysis shall be appropriate to the complexity of the process and shall
