Functional Safety and Hazard Analysis Training

Functional Safety and Hazard Analysis Training Course by Tonex

Functional Safety and Hazard Analysis covers overall safety and hazard analysis depending on a system or equipment operating correctly in response to its inputs. Learn ow to address Functional safety and hazards and carry out and the level of performance required of each safety function to meet the expectations and requirements.

Functional safety needs defined processes, hazard free and certified sub-systems and components. Learn the role of  active and passive systems in Functional safety and Hazard analysis including  safety-related system comprises for equipment,  hardware, software and human elements.

Safety and Hazard analysis practices are becoming more regulated and standardized practices for designing and testing equipment and products such as ISO 26262 addresses t issues with safety critical components. ISO 26262 is a derivative of IEC 61508, the generic functional safety standard for electrical and electronic (E/E) systems.

 IEC 61508-4 defines E/E/PE ratings or electrical/electronic/programmable electronic.as based on electrical and/or electronic and/or programmable electronic technology.

CENELEC , European Committee for Electrotechnical Standardization provides a process to implement a consistent approach to the management RAMS for the railway industry.

Safety and Hazard analysis training covers all the requirements for standards dealing with functional safety of electrical/electronic and programmable electronic systems and details safety integrity levels, the safety lifecycle and many other requirements needed to ensure functional safety including: requirements, project implications, maintenance/operational implications, Checklists, and best practices.
