 Hi, my name's Rick Owen. I currently work for the CFA as an operation officer in state training. But today I'm here representing the fire smoke coalition and we're about to do some test burns after our theory session this morning. So we're going to use some detectors and burn some different household products and just see what the byproducts can bust in our. So Jason's got a range of just household products, things we get in a building. So there's some PVC pipe, carpet and foam headrest or foam cushion like would be on a sofa. And he's not actually going to burn them. We're just going to apply heat to them so that they start off-gassing or vaporizing and produce some products of combustion. So we won't see large amount of flame or smoke but it'll demonstrate with the use of each of the detectors, which everyone has, just how dangerous the off-products are. We've also got it set up in front of us is the air array on the tripod, which is a remote one and he's got a yellow one next to him and that actually data logs and sends wirelessly back to a computer in there. So everybody inside can be watching the results of what's going on now. Now ideally for us, if we'll use those that it has about we can get about three kilometers away and we can still get our information back to the incident control center. Well, they learned today was more the dangers of smoke and it's not the flame that gets us. It's the products of combustion either entering our skin or we're inhaling it or even the worst practice of not washing our hands and we're putting our hands in our mouth or eating to ingest in stuff. So it's probably about hygiene and just the off the products of combustion, which really are nasty to us. The importance of B.A. not just realizing that B.A. is for internal. They realize that it's external. It's good hygiene practice for just being out in the smoke. Hopefully we reinforce that we should be laundering our equipment or our PPC as the instruction says and it's basically says one where one wash. So we just got to start thinking about ourselves because it's not the won't knock us off today. It's going to get us in 20 years. The lower the temperature, the smoke isn't as buoyant and it hangs around. And so we actually like a pot on a stove is probably the worst fire we go to for effective byproducts. If it's a really hot fire and it's vented and it's burst out through the roof, most of it goes away. But when it's caught inside a kitchen, an old nana or mum is in there being just, it's only a pot on the stove. We get very high levels of hydrogen cyanide, which isn't a good thing. So low temperature fires and low intensity are like a smoldering fires worse for us. The two, which are the nasty one we work together. We talk a lot about carbon monoxide and and hydrogen cyanide. But then you go through through things like acrolein, ammonia, phosgene, the isocyanates. You know, there's thousands of chemicals and we can never really monitor them that well because it's very hard to replicate the same fire because we air entrainment changes, fuel changes. We just can't make the same fire. And that's what's made it hard for research to for us to do a lot of research because we can't get that repeatable fires. My duty of care is to the occupant and the community first. So when I hand it back, I want to make sure it is safe and I've looked after them because otherwise we can put the fire out and then fail public and give them and put them into it. Yeah, it looks clean. Our eyes aren't a good indicator of how clean it is, but we could have nasty gases still floating around. So for me, there's probably two things we need to think about. We need to think about making sure before we take our BA off, we've made an informed decision using some sort of detection equipment and do that in fresh air, take it off in fresh air. And then think about our hygiene. Now, our hygiene should be two parts. One should be washing our equipment and one should be washing ourself. So that would involve, first up for me would be wash around the neck and where our interface of our BA and flush hood is and our hands because our hands are actually five times dirty than our neck because we've been working. And then once I get so I do some sort of cleaning regime on scene and then soon as I get home or I get a shower, a full shower to wash the particulates off. So we get rid of the absorption risk. So we're very good at looking after our equipment as because fire is generally quite clean people. But we just need to start focusing on ourselves that we're clean. So for 20 years, we haven't had a chronic long term exposure and we're not injured. So we've just concluded the fire smoke symposium for 2018. So we've had two days of theory and practice training and we've had approximately 200 people through it. Now, that's just not CFA people. We've had AV police, MFB, Aviation, Fire and Rescue, WorkSafe, EPA. So they've all learned about dangers of fire smoke and some of the products of combustion. Hopefully now we've started the ball rolling and that can be the catalyst and go back and change some culture within our organisation.
