Just quickly, still relatively new, but if you go for a bush fire wether first response or strike team, your meant to wear PBI right? so what happens if that bush fire causes a house to go up, as does happen, would you just do your thing staying out of the house or maybe call in an appliance with people wearing level 3 or gold? also how do you tell if your pants and boots are level 1, 2, or 3? recently i read something about having liners in pants??? and what is the difference between rural and structural boots? sorry for my ignorance/
