Environmental Hazard Analysis

This is the full-length (one hour) session on Environmental Hazard Analysis (EHA), which is Task 210 in Mil-Std-882E. I explore the aim, task description, and contracting requirements of this Task, but this is only half the video. In the commentary, I then look at environmental requirements in the USA, UK, and Australia, before examining how to apply EHA in detail under the Australian/international regime. This uses my practical experience of applying EHA. 

You Will Learn to:

  • Conduct EHA according to the standard;
  • Record EHA results correctly;
  • Contract for EHA successfully;
  • Be aware of the regulatory scene in the US, UK, and Australia;
  • Appreciate the complexities of conducting EHA in Australia; and
  • Recognize when your EHA program requires specialist support.
This is the seven-minute demo of the full-length (one hour) session on Environmental Hazard Analysis.

Topics: Environmental Hazard Analysis

  • Environmental Hazard Analysis (EHA) Purpose;
  • Task Description (7+ slides);
  • Documentation, HAZMAT & Contracting (2 slides each);
  • Commentary (8 slides); and
  • Conclusion.

Environmental Hazard Analysis – Full Version

Introduction

Hi, everyone, and welcome to the Safety Artisan. Today, we’re going to be talking about Environmental Hazard Analysis – Big topic! I’m covering this as part of the series on the System Safety Engineering Standard – Mil. Standard 882E. But it doesn’t really matter what standard we are using the topic is still relevant.

So, Environmental has analysis – it’s a big topic because we’re going to cover everything, not just hazards. At the end of this session, you should be able to enjoy three benefits. First of all, you should know how to approach Environmental Hazards Analysis both from the point of view of the requirements, the Hazard Analysis itself (the process), and some national and international variations in the English-speaking world. So, you should know how to do the basics and also recognize when maybe you need to bring in a specialist. But maybe most important of all, number three is you should have the confidence to be able to get started. So I’m hoping that this session is really going to help you get started, know what you can do, and then maybe recognize when you need to bring in some specialist help or go and seek some further information.

As you’ll see, it’s a big, complex subject. I can get you started today, but that’s all I can do in one session. In fact, I think that’s all anyone can do in one session. Anyway, let’s get on with it and see what we’ve got.

Environmental Hazard Analysis, Mil. Standard 882E Task 210

Environmental Hazard Analysis, which is Task 210 under Mil. Standard 882E. So’ let’s look at what we’re going to talk about today.

Topics for this Session

You’ll see why it’s going to be quite a lengthy session. I think it will last an hour because we’re going to go through the Purpose and Task Description of Environmental Hazard Analysis as set out in the Mil. Standard. And it says seven-plus slides because there are seven mainstream slides plus some illustrations in there as well. Then we’ve got a couple of slides each on Documentation, Hazardous Materials or HAZMAT, and Contracting. And then eight slides of Commentary and this is the major value add because I’ll be talking about applying Environmental Hazard Analysis in a US, UK, and Australian jurisdiction under the different laws, which I have some experience of.

I worked closely with environmental specialists on the Eurofighter Typhoon project, and I’ve also worked closely with the same specialists on US programs that had been bought by different countries. Finally, I’ve been closely involved in a major environmental – or safety and environmental – project here in Australia. I’ve been exposed and learned the hard way about how things work or don’t work here in Australia. So I’ve got some relevant experience to share with you, as well as some learned material to share with you. And then a little Conclusion, because I say this will take us an hour so there’s quite a lot of material to cover. So, let’s get right on with it.

EHA

So the purpose of Environmental Hazards Analysis, or EHA, as it says, is to support design development decisions. Now all of the 882 tasks are meant to do this, but actually, the wording in Task 210 is the clearest of all of them. Really makes it explicit what we’re trying to do, which is excellent.

So we’re going to identify hazards throughout the life cycle – cradle to grave, whatever system it is. And we’re going to document and record those hazards and their leading particulars within the Hazard Tracking System or Hazard Log, as we more often call it. We’re going to manage the hazards using the same system safety process in Section Four as we use for safety – and this is the process that you will have heard and the other lessons that I’ve been giving. And very often under 882, Safety and Environmental Hazards are considered together. There are pros and cons with that approach, but nevertheless, a lot of the work is common. We’ll see why later on.

And in this American standard, it says we are to provide specific data to support the National Environmental Policy Act and executive order requirements. So the NEPA is an American piece of legislation and therefore I use this colour blue to indicate anything that’s an American-specific requirement. If you’re not operating in America, you’ll need to find the equivalent to manage to and to comply with. Moving on.

Task Description (T210) #1

Let’s start going through the task description. So really excellent words here “integrating environmental considerations into the systems engineering process”. And as I’ve said repeatedly in this series, we need the systems engineering process to give us the context in order to route the safety engineering process, to give us traction, and keep us connected to the real world. And it’s great that the EHA task recognizes that and explicitly says that’s what this is about. So it’s good guidance for people who use it.

We’re assuming that a contractor is going to follow the EHA process, but whoever it is, they need to start early. So that once the systems engineering process is initiated, whoever is doing the analysis will start identifying and managing hazards in the requirements phase, ideally, and then using those system safety processes to… [buy the video to get the full transcript].

So, it just remains for me to say thank you very much for listening. And that’s been Environmental Hazard Analysis. So, thank you very much and goodbye.
