Process Hazard Analysis cont'd

DOE-HDBK-1101-2004

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 completed prior to process startup.

(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

(vii) An appropriate equivalent methodology.

(3)

The process hazard analysis shall address:

(i)

The hazards of the process;

(ii)

The identification of any previous incident which had a likely potential for

catastrophic consequences in the workplace;

(iii)

Engineering and administrative controls applicable to the hazards and

their interrelationships such as appropriate application of detection

methodologies to provide early warning of releases. (Acceptable detection

methods might include process monitoring and control instrumentation

with alarms, and detection hardware such as hydrocarbon sensors.);

(iv)

Consequences of failure of engineering and administrative controls;

(v)

Facility sitting;

(vi)

Human factors; and

(vii)

A qualitative evaluation of a range of the possible safety and health effects

of failure of controls on employees in the workplace.
