We all understand the dangers of smoke inhalation in fires. But what about the site of the fire a few days after it was put out? It looks clean, maybe even lost the smell... Is it something to worry about, or you can rush straight in, wearing your shorts and a t-shirt? Well, I guess I would not be that reckless, but if I can be honest - I don't think I would care that much about protecting myself either... At least that was me before the talk to dr Gavin Horn from UL FSRI. Gavin spent more than a decade investigating the environment of post-fire scenes. And these places are where many of us work, almost on daily basis. Firefighters, investigators, fire researchers, constructors and demolished... And the scenes do certainly hide some threats within. In this episode you will learn a lot about them, and how these threats change as the environment evolves. More than that, Gavin is a pretty down-to-earth guy and does not imply you should dress for an investigation in a NASA space suit. You have to balance the risks related to contamination through inhalation and absorption, with risks of overheating, falling or cutting yourself, and as well with the capability to do the actual work wearing PPE. That is not the kind of discussion I get with my own H&S experts, and I appreciate this smart and holistic view a lot. To learn more about the environment of fire scenes, you MUST read this excellent paper by Gavin Horn et. al.
