Explore subsystem hazard analysis under mil-std 882, detailing purposes: verify compliance, identify new hazards, and recommend control measures, while examining system models, scope, and human as a component.
Analyze subsystems under mil std 882 echo to verify compliance, identify new hazards, and recommend control measures, viewing subsystems in a bottom-up hierarchy with humans as system components.
This task 204 part 2 lecture explains verifying subsystem compliance with requirements, flow-down of design requirements, and identifying hazards with hazard analysis and hazard tracking.
Task 204 subsystem hazard analysis under mil-std 882 verifies compliance, identifies new hazards, and recommends controls for subsystems, including software and human factors in a bottom-up system model.
Analyze system hazards under task 205 of Mil standard 882 ecosystem safety standard, identify hazards and mitigations within integrated system design, including software, human interfaces, and emergent hazards.
Identify and assess hazards from operating and support activities through hazard analysis, evaluate adequacy of procedures, and integrate risk mitigation, reporting, and legacy system considerations under the standard.

Introduction
Hello, everyone, and welcome to the Safety Artisan, where you will find professional, pragmatic, and impartial instruction on all things system safety. I'm Simon – your host for today, as always and it's the fourth of April 22. With everything happening in the world, I hope this video finds you safe and well.
Sub-System Hazard Analysis
Let's move straight on to what we're going to be doing. We're going to be talking today about subsystem hazard analysis and this is task 204 under the military standard 882E. Previously we've done 201, which was preliminary hazard identification, 202, which is preliminary hazard analysis, and 203, which is safety requirements hazard analysis. And with task 204 and task 205, which is system has analysis, we're now getting stuck into particular systems that we're thinking about, whether physical or intangible. We’re thinking about the system under consideration and I'm getting into that analysis.
Topics for this Session
So, the topics that we're going to cover today, I've got a little preamble to set things in perspective. We then get into the three purposes of task 204. First, to verify compliance. Secondly, to identify new hazards. And thirdly, to recommend necessary actions. In fact, that would be recommended control measures for hazards and risks. We've got six slides of task description, a couple of slides on reporting, one on contracting, and then a few slides on some commentary where I put in my tuppence worth and I'll hopefully add some value to the basic bones of the standard. It's worth saying that you'll notice that subsystem is
highlighted in yellow and the reason for that is that the subsystem and system hazard analysis tasks are very, very similar. They're identical except for certain passages and I've highlighted those in yellow. Normally I use a yellow highlighter to emphasize something I want to talk about. This time around, I'm using underlining for that and the yellow is showing you what these are different for subsystem analysis as opposed to system analysis. And when you've watched both sessions on 204 and 205, I think you'll see the significance of why I've done that.
