Mil-Std-882E Safety Analysis

Health Hazard Analysis

In this full-length (55-minute) session, The Safety Artisan looks at Health Hazard Analysis, or HHA, which is Task 207 in Mil-Std-882E. I explore the aim, description, and contracting requirements of this complex Task. It covers: physical, chemical & biological hazards; Hazardous Materials (HAZMAT); ergonomics, aka Human Factors; the Operational Environment; and non/ionizing radiation. I will outline how to implement Task 207 in compliance with Australian WHS. (See also other lessons for specific tools and techniques, such as Human Factors analysis methods.)

This is the seven-minute-long demo. The full version is a 55-minute-long whopper!

Health Hazard Analysis: Transcript


Hello, everyone, and welcome to the Safety Artisan. I’m Simon, your host, and today we are talking about health hazard analysis.

Task 207: Health Hazard Analysis

This is Task 207 in the Mil. standard, 882E approach, which is targeted for defense systems, but you will see it used elsewhere. The principles that we’re going to talk about today are widely applicable. So, you could use this standard for other things if you wish.

Topics for this Session

We’ve got a big session today so I’m going to plough straight on. We’re going to cover the purpose of the task; and the description; the task helpfully defines what a health hazard is; and says what health hazard analysis, or HHA, shall provide in terms of information. We talk about three specialist subjects – hazardous materials or hazmat, ergonomics, and operating environment. Also, radiation is covered, as another specialist area. Then we’ll have some commentary from myself.

Now the requirements of the standard of this task are so extensive that for the first time, I won’t be quoting all of them, word for word. I’ve actually had to chop out some material, but I’ll explain that when we come to it. We can work with that but it is quite a demanding task, as we’ll see.

Task Purpose

Let’s look at the task purpose. We are to perform and document a health hazard analysis to identify human health hazards and evaluate what it says, materials and processes using materials, etc, that might cause harm to people, and to propose measures to eliminate the hazards or reduce the associated risks. In many respects, it’s a standard 882-type approach. We’re going to do all the usual things. However, as we shall see it, we’re going to do quite a lot more on this one.

Task Description #1

So, task description. We need to evaluate the potential effects resulting from exposure to hazards, and this is something I will come back to again and again. It’s very easy dealing in this area, particularly with hazardous materials, to get hung up on every little tiny amount of potentially hazardous material that is in the system or in a particular environment and I’ve seen this done to death so many times. I’ve seen it overdone in the UK when COSHH, a control of substance hazardous to health, came in in the military. We went bonkers about this. We did risk assessments up the yin-yang for stuff that we just did not need to worry about. Stuff that was in every office up and down the land. So, we need to be sensible about doing this, and I’ll keep coming back to that.

So, we need to do as it says; identification assessment, characterization, control, and communicate assets in the workplace environment. We need to follow a systems approach, considering “What’s the total impact of all these potential stressors on the human operator or maintainer?” Again, I come from a maintenance background. The operator often gets lots of attention because a) because if the operator stuffs up, you very often end up with a very nasty accident where lots of people get hurt. So, that’s a legitimate focus for a human operator of a system.

But also, a lot of organizations, the executive management tend to be operators because that’s how the organization evolves. So, sometimes you can have an emphasis on operations and maintenance and support, and other things get ignored because they’re not sexy enough to the senior management. That’s a bad reason for not looking at stuff. We need to think about the big picture, not just the people who are in control…

So, that is the end of the session. Thank you very much for listening. And all that remains for me to say is thanks very much for supporting the work of the Safety Artisan and tuning into this video. And I wish you every success in your work now and in the future. Goodbye.
