Process Hazard Analysis

DOE-HDBK-1101-96

(F) Design codes and standards employed;

(G) Material and energy balances for processes built after May 26, 1992; 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 identify, evaluate, and control the hazards involved in

the process. Employers shall determine and document the priority order for conducting

process hazard analyses based on a rationale which includes such considerations as extent

of the process hazards, number of potentially affected employees, age of the process, and

operating history of the process. The process hazard analysis shall be conducted as soon as

possible, but not later than the following schedule:

(i)

No less than 25 percent of the initial process hazards analyses shall be completed by

May 26, 1994;

(ii)

No less than 50 percent of the initial process hazards analyses shall be completed by

May 26, 1995;

(iii) No less than 75 percent of the initial process hazards analyses shall be completed by

May 26, 1996;

(iv) All initial process hazards analyses shall be completed by May 26,1997.

(v)

Process hazards analyses completed after May 26, 1987 which meet the

requirements of this paragraph are acceptable as initial process hazards analyses.

These process hazard analyses shall be updated and revalidated, based on their

completion date, in accordance with paragraph (e)(6) of this standard.

(2)

The employer shall use one or more of the following methodologies that are appropriate to

determine and evaluate the hazards of the process being analyzed.

(i)

What-If;

(ii)

Checklist;

(iii) What-If/Checklist;

(iv) Hazard and Operability Study (HAZOP);

(v)

Failure Mode and Effects Analysis (FMEA);

(vi) Fault Tree Analysis; or
