i think jaff was mentioning not wearing having pbi for internal firefighting. (which PBi is needed for)
PBI ain't necessary for nothin'! As long as you're wearing something that conforms to AS 4967(int):2002, you're all good (Hello Nomex!)
Numbers my quickwitted but disturbed friend, my quote had the key word "new" in it thereby implying that they were not CABA qualified previously and that their current level 1 PPE wasn't up to structural standard!!
Now personaly I'd send em in, in budgie smugglers and chainsaw chaps ,with negative pressure sets on, but I'm old school
Oh touche! Mr.(or Mrs.) Jaff you certainly have me there.
As long as those are AS 4967:2002 compliant buggie smugglers and the chaps have the backside cut out of them, I am a fan of your improved SOP's.
Grab a Proto and start sucking!
