White Paper: Random versus Systematic Failures – Issues and Solutions
Functional safety standards provide definitions of two different categories of failures: random failures and systematic failures. These were created during the standards committee discussions of failure types to be modeled in the probabilistic failure analysis. It was decided that random failures are counted in the probabilistic failure rate analysis and…
Training Course: Fire and Gas Detection Design and Technology
This course is developed by an exida certified training provider. It provides attendees a comprehensive understanding of all aspects of Fire and Gas Detection Technology; from performance based design (fire and gas mapping) through to practical maintenance requirements, including: Role & Action of Fire & Gas Detection Performance Requirements Design…
Blog Entry: The Crossroads of Alarm Management and Process Safety
Recently I was reading The Manufacturing Operations Technology Viewpoints blog and came across an interest post on Alarm Management that cites exida’s Alarm Management cheat sheet. The blog post entitled The Crossroads of Alarm Management and Process Safety is a great summary for any one who needs a primer on…
Service: Process Hazard Analysis (PHA) Facilitation
The main objective of a Process Hazards Analysis (PHA) is to identify potential hazards posed by the process and associated equipment. The PHA is the first step in the functional safety lifecycle. This first step is critical, as adequate risk reduction measures cannot be implemented for hazards that are not…
