(5)

The employer shall establish a system to promptly address the team's findings and recommendations; assure

that the recommendations are resolved in a timely manner and that the resolution is documented; document

what actions are to be taken; complete actions as soon as possible; develop a written schedule of when these

actions are to be completed; communicate the actions to operating, maintenance and other employees whose

work assignments are in the process and who may be affected by the recommendations or actions.

(6)

At least every five (5) years after the completion of the initial process hazard analysis, the process hazard

analysis shall be updated and revalidated by a team meeting the requirements in paragraph (e)(4) of this

section, to assure that the process hazard analysis is consistent with the current process.

(7)

Employers shall retain process hazards analyses and updates or revalidations for each process covered by

this section, as well as the documented resolution of recommendations described in paragraph (e)(5) of this

section for the life of the process.

Intent

PrHA is a systematic method to identify and assess process hazards, and is the cornerstone of a PSM

program. PrHAs can be used to identify causes and consequences of potential accidents associated

with equipment, instrumentation, utilities, human performance, external factors, and natural

phenomena such as earthquakes. The objective of PrHA is to determine areas of excessive risk

where preventative and mitigative measures may be warranted to better control the hazards. PrHAs

can help identify accident scenarios leading to worker injuries or fatalities, property damage, public

exposure to chemicals, environmental impacts, or other adverse consequences.

Corresponding DOE Programs and Requirements

General Guidance DOE-HDBK-1100-96, Chemical Process Hazards Analysis, provides detailed

information on PrHA methodologies and the PrHA process. DOE guidance available to support the

process hazard analysis team includes DOE/EH-0340, Example Process Hazard Analysis of a

Department of Energy Water Chlorination Process.

Safety Analyses DOE O 430.1, LIFE CYCLE ASSET MANAGEMENT, requires a preliminary

safety assessment as part of the project management system prior to execution of design plans. DOE

requires that hazard analyses be performed to support SARs under DOE 5480.23, NUCLEAR

SAFETY ANALYSIS REPORTS, and DOE-STD-1027-92. PrHAs will not replace SARs, nor will

SARs replace PrHAs; they are conducted to satisfy two independent sets of requirements.

Therefore, conduct of a PrHA does not necessarily mean that a SAR must be performed or vice

versa. However, because a PrHA is a systematic method to identify accident scenarios, it may be

used as an integral part of the overall hazards analysis required in the development of a SAR, when a

SAR is necessary. When the PrHA is used to support the SAR, require that all PSM documents used

to develop the PrHA should be referenced in the appropriate SAR chapter. References and

summaries should include not only the results of the PrHA, but also all documents concerning the

resolution of the PrHA team's findings.

OSHA requires that PrHAs address facility siting issues (e.g., the physical spacing between

processes, or between a process and administrative facilities). Consideration of natural phenomenon

hazards is also an appropriate siting issue, especially for new proposed facilities. DOE O 420.1,

FACILITY SAFETY, identifies safety analysis requirements for various types of facilities and

requires consideration of natural phenomena hazards relative to facility siting.
