·  When appropriate, site surveys will be planned to further refine the analysis and allow
the analysis to be more specific. Site visits should be conducted for the purpose of
data collection, hazard control validation, verification and update following a process
or configuration change. The information collected during the site surveys will be
used to further refine the O&SHA.
·  Analyses must be revised to include new information, and a quality control review
must be performed.
·  Conformance to existing codes, standards, and laws are considered minimal system
safety requirements.
·  Hazard analysis and risk assessment are required to assure elimination and mitigation
of identified risks.
·  Safety, health, and environmental program activities should be conducted in
conjunction with facility system safety efforts.

The concept of operational risk management is the application of operational safety and facility system
safety. More explicit information on Operational Risk management is found in Chapter 15.
12.4.2 System Safety Program Plan (SSPP)
The first task the SSWG performs is the preparation of the System Safety Program Plan (SSPP). It is
customary to implement a facility system safety program plan that describes system safety activities and
tasks from inception of the design through final commissioning of the facility. The plan establishes the
system safety organization, the initiation of a SSWG, and the analysis efforts conducted. When approved,
it becomes the road map for the project's system safety effort. This plan tailors the SSPP requirements to
the needs of the specific project. The SSPP establishes management policies and responsibilities for the
execution of the system safety effort. The SSPP should be written so the system safety tasks and activity
outputs contribute to timely project decisions. Evaluation of system safety project progress will be in
accordance with the SSPP.
Example elements of the Facility SSPP are as follows:
·  Establishment of project risk acceptance criteria based on consideration of the user's
recommendations. The acceptable level of risk in a facility is an expression of the
severity and likelihood of an accident type that the using organization is willing to
accept during the operational life of the facility. The goal is to identify all hazards and
to eliminate those exceeding the defined level of acceptable risk. While this is not
always possible, the analysis conducted will provide the information upon which to
base risk acceptance decisions.
·  A specific listing of all tasks, including hazard analyses, that are a part of the design
system safety effort; designation of the responsible parties for each task. Optional
tasks should be designated as such, listing the conditions which would initiate these
tasks.
·  Establishment of a system safety milestone schedule. Since the purpose of the hazard
analysis is to beneficially impact the design, early completion of these analyses is vital.
The schedule for analysis completion must complement the overall design effort.
·  Establishment of procedures for hazard tracking and for obtaining and documenting
residual risk acceptance decisions.
·  Outline of procedures for documenting and submitting significant safety data as
lessons learned.
·  Establishment of procedures for evaluating proposed design changes for safety impact
during the later stages of design or during construction after other safety analysis is
complete.
·  Establishment of a communication system that provides timely equipment
requirements and hazard data to the facility design. This is necessary when equipment
to be installed or utilized within the facility is being developed or procured separately
from the facility.

Other factors influencing the SSPP are overall project time constraints, manpower availability, and
monetary resources. The degree of system safety effort expended depends on whether the project replaces
an existing facility, creates a new facility, involves new technology, or is based on standard designs. A
more detailed discussion of each of the elements of a System Safety Program Plan is in Chapter 5.
12.4.3 Facility System Safety Working Group (SSWG)
The system safety process starts with the establishment of the system safety working group (SSWG). The
SSWG is often tasked to oversee the system safety effort throughout the facility life cycle. The SSWG
