State...Everything except Rural.
Region....Only when you will wear BA.
the uniform manual is supposed to be the definitive source. If the poster contradicts that then get your GO to raise it to the region. (both the uniform manual and poster are issued by state, so when you say 'region' I assume you mean the memo? the memo is just supposed to be reinforcing the state policy.)
quote from the uniform manual (under 'structural ensemble' and a picture of someone wearing PBI Gold):
APPLICATION
To be worn at all structure and other fires and / or incidents where the risk dictates the necessity for structural firefighting PPE to be worn.
The PPE is worn during structural fire fighting and while partaking in drill or training exercises.
The PPE may be worn in other situations at the discretion of the Officer-in-Charge.
It is not to be worn at rural fire incidents and it is not to be mixed with rural ensemble.
Hazmat is an example where this contradicts with SOP. To do anything in Hazmat operations, its PBI Gold or Higher, required.
No it's the 'rural ensemble' for hazmat according to the uniform manual (usually just a shorts/pants and t-shirt are worn under the splash/gas suit from what I've seen).
IF youve got PBI, wear it...its a higher level of protection, from the elements of danger we encounter.. CFS Motto: "Safety First".
where you think you should wear PBI Gold is a different matter. If you don't like the current rules, lobby to get them changed.
Now...the Storm Damage/Weather Related incidents....Poster: Yes, Memo: No.
I would have thought storm/weather related things are what the wet weather gear is for but agreed it does say you can wear PBI Gold to those. If you're following the poster I would think you're on safe ground.
