SYSTEM SAFETY ENGINEERING
The System Safety Engineering is normally worked in unison with reliability engineering efforts. Information provided by the FMECA and RCM analysis play an important role in the System Safety Analysis efforts. MIL-STD-882 and MIL-STD-882D is typically used as a guide to Hazard Analysis, Fault Tree, and if dealing with electrical circuits Sneak Circuit Analysis is performed.
RMS Aerospace can support your technical requirements and tailor a safety program to comply with requirements. Hazard Analyses is a technique which by qualitative or quantitative analysis is used to identify hazards, their causes and effects.
The hazard elimination, or risk mitigation would be documented in the hazard analysis. This analysis can be conducted to identify hazard associated with a system, subsystem, components, ground support equipment, personnel ,facilities, GFE, and take into consideration their interrelationship and impact with the logistic support, training, maintenance, and operational environments.
RMS Aerospace can assist you in the following areas of System Safety Engineering:
- System Safety Program Plan (SSPP)
- Probabilistic Risk Analysis (PRA)
- Functional Hazard Analysis (FHA)
- Hazard Severity Analysis (HSA)
- Risk Mitigation Plan (RMP)
- Fault Tree Analysis (FTA)
SYSTEM SAFETY PROGRAM PLAN (SSPP)
The Safety policy shall be formulated during the 'Concept and Demonstration phase of the system life cycle.
A 'System Safety Program Plan' shall be prepared when applicable in accordance with the requirements defined in the SOW. The primary purpose of the system safety program plan is to establish the organization and define activities to identify possible hazards (risk of damage, injury, or death) and to analyze and reduce the risk of their occurrence.
PROBABILISTIC RISK ANALYSIS (PRA)
Is a systematic method for addressing the risk triplet as it relates to the performance of a complex system to understand likely outcomes, sensitivities, areas of importance, system interactions, and areas of uncertainty. The risk triplet is the set of three questions that the PRA uses to define Probabilistic Risk Assessment PRA captures these three basic questions (1) What can go wrong? (2) How likely is it? and (3) What are the consequences?
FUNCTIONAL HAZARD ANALYSIS (FHA):
The functional hazard analysis FHA is a crucial component of any aerospace certification, is being increasingly recommended Aerospace Recommended Practice-ARP 4754, SAE94 as a means of performing hazard identification. However, many of the available example applications of this approach, including that given in ARP 4761, SAE95 are illustrated either for aircraft-level functions or sub-system functions with obvious and visible functional effects.
RISK MITIGATION PLAN (RMP):
The purpose of this risk mitigation plan RMP is to outline the risks that have been identified by the team as having highest probability to impact on schedule. These risks have been categorized as High, Medium and Low.
FAULT TREE ANALYSIS (FTA):
The Fault Tree Analysis is a topdown analysis. It takes on a deductive approach defining the events and sub-event, which may cause the top event to occur. The relationship between these events is governed by their logical relationship to each other.
