Learn Functional Hazard Analysis

Learn Functional Hazard Analysis.

In this full-length (40-minute) session, The Safety Artisan looks at Functional Hazard Analysis, or FHA, which is Task 208 in Mil-Std-882E. FHA analyses software, complex electronic hardware, and human interactions. We explore the aim, description, and contracting requirements of this Task, and provide extensive commentary on it. (We refer to other lessons for special techniques for software safety and Human Factors.)


Hello, everyone, and welcome to the Safety Artisan; Home of Safety Engineering Training. I’m Simon and today we’re going to be looking at how you analyze the safety of functions of complex hardware and software. We’ll see what that’s all about in just a second.

Functional Hazard Analysis

This, as you can see, functional hazard analysis is Task 208 in Military Standard 882E.

Topics for this Session

What we’ve got for today: we have three slides on the purpose of functional hazard analysis, and these are all taken from the standard. We’ve got six slides of task descriptions. That’s the text from the standard plus we’ve got two tables that show you how it’s done from another part of the standard, not from Task 208. Then we’ve got “update” and “recording”, another two slides. Contracting, two slides. And five slides of commentary, which again include a couple of tables to illustrate what we’re talking about.

Functional Purpose HA #1

What we’re going to talk about is, as I say, functional hazard analysis. So, first of all, what’s the purpose of it? And in classic 882-style, Task 208 is to perform this functional hazard analysis on a system or subsystem or more than one. Again, as with all the other tasks, it’s used to identify and classify system functions and the safety consequences of functional failure or malfunction. In other words, hazards.
