SAFETY LIFE CYCLE WORK PRODCUTS
Ensure your system's safety with our comprehensive ARP4754/4761 lifecycle services. We expertly handle every stage, starting with Functional Hazard Assessment (FHA) to pinpoint potential hazards and their impacts. Next, we perform Preliminary System Safety Assessment (PSSA) to evaluate and address safety risks in your preliminary designs. Finally, we deliver a detailed System Safety Assessment (SSA) to guarantee your system meets all safety requirements before certification.
SAFETY PROCESSES ANDÂ MANAGEMENT
Effective safety management is crucial for project success and maintaining compliance with safety standsrds . Our approach to safety management encompasses thorough planning and tracking of safety activities as well as anomalies to ensure ongoing system integrity.
Safety Planning: We start with a tailored safety management plan that outlines strategies for identifying, assessing, and mitigating risks throughout the system lifecycles.
Safety Anomaly Tracking: Once the project has started, continuous monitoring and tracking of safety anomalies is essential. We implement robust processes for detecting and documenting safety issues as they arise. By systematically investigating anomalies and analyzing their causes, we can implement corrective actions to address and resolve them effectively. Our tracking system ensures that safety issues are promptly addressed and that any lessons learned are applied to prevent future occurrences.
SAFETY ANALYSIS
Fault Tree Analysis (FTA) and Failure Modes and Effects Analysis (FMEA) are critical techniques used to ensure the safety and reliability of complex systems.
Fault Tree Analysis (FTA): FTA is a top-down approach used to identify and analyze the potential causes of system failures. By constructing a fault tree diagram, we systematically trace how various failures can lead to undesirable events. This method helps in understanding the relationships between different faults and their impact on system safety..
​
Failure Modes and Effects Analysis (FMEA): FMEA is a bottom-up technique that examines each component of a system to identify potential failure modes and their consequences. By evaluating the effects of each failure mode on the system's performance, we can prioritize risks and implement design changes to enhance reliability and safety. FMEA helps in identifying critical failure points and developing strategies to address them before they impact system operation.
Together, FTA and FMEA provide a comprehensive approach to risk assessment, ensuring that potential issues are identified and addressed early in the design process. Our expertise in these analyses helps you build safer, more reliable systems while meeting stringent industry standards.
