system can facilitate the final safety assessment. This review may identify safety features that might
otherwise be overlooked during the inspection. A Hazard Tracking Log can generate a checklist for safety
items that should be part of this inspection.
The results of the occupancy inspection can serve as a measure of the effectiveness of the SSPP. Any
hazards discovered during the inspection will fall into one of two categories. A hazard that was previously
identified and the corrective action to be taken to control the determined hazard, or a hazard not previously
identified requiring further action. Items falling in this second category can be used to measure the
effectiveness of the SSPP for a particular facility.
SSPP tasks appropriate for the construction phase are as follow:
·  Ensure the application of all relevant building safety codes, including OSHA, National
Fire Protection Association, and FAA Order 3900.19B safety requirements.
·  Conduct hazard analyses to determine safety requirements at all interfaces between the
facility and those systems planned for installation.
·  Review equipment installation, operation, and maintenance plans to make sure all
design and procedural safety requirements have been met.
·  Continue updating the hazard correction tracking begun during the design phases.

·  Evaluate accidents or other losses to determine if they were the result of safety
deficiencies or oversight.
·  Update hazard analyses to identify any new hazards that may result from change
orders.
In addition, guidance for conducting a Hazardous Material Management Program (HMMP) is provided in
National Aerospace Standard (NAS) 411. The purpose of a HMMP is to provide measures for the
elimination, reduction, or control of hazardous materials. A HMMP is composed of several tasks that
complement an SSPP:
·  HMMP Plan
·  Cost analysis for material alternatives over the life cycle of the material
·  Documented trade-off analyses
·  Training
·  HMMP Report
12.3 Existing Facilities
Facility system safety is also successfully applied in the evaluation of risks associated with existing
facilities. There may be a need to establish a System Safety Working Group in order to conduct hazard
analysis of existing facilities. If previous analyses are not available, it will be appropriate to initiate these
analysis efforts. There are benefits that can be gained by systematically reviewing physical structures,
processes, and equipment. Additional safety related risks may be uncovered and enhancements provided to
mitigate these risks. Secondary benefits can be enhancements and process, productivity, and design.
12.3.1 Re-Engineering of Structures and Equipment
When major changes to existing facilities, equipment or structures are contemplated, a rigorous system
safety activity that includes hazard analysis should be conducted.
Analysis of Existing Systems
In order to accomplish the analysis of existing systems it is appropriate to establish a working group and to
identify hazard analysis techniques that will be used. The following presents an example of such an
activity. The concept of Operational Risk Management is applied. (See Chapter 15 for additional
information. It is appropriate to form an Operational Risk Management Group (ORMG) in order to
perform hazard analysis. Analysis examples are provided, e.g., operating and support hazard analysis,
requirements cross check analysis, risk assessment, and job safety analysis.
Facility Risk Categories
The completion of the initial Preliminary Hazard List (PHL) permits categorization of the planned facility
into risk categories. Categorizing is based on several factors, such as number of people exposed, type and
degree of inherent hazard of operation, criticality of the facility to the National Air Space (NAS),
vulnerability, and cost. Inputs include whether or not the facility is “one of a kind” or a standard design
and how it impacts the rest of the installation. For example, the failure or destruction of a facility used to
house emergency power or one through which communication lines run may shut down an entire airport or
region. The designation should reflect the local concern for operational safety and health risks presented by
the facility and its mission. It is critical that the appropriate risk categorization be applied in each instance.

Several examples of categorization methods are presented below to illustrate their risk ranking approaches
