In an earlier message Toidi said :
I thought that a Stop Message meant that no further resources were required and the fire is under control but not necessarily out.
With reference to a tactical mode for an AFA, it's all about justification - In Strathclyde they are taught to put back a tactical mode with each informative at all working incidents. The dilemma is that do you perceive an AFA as a working incident?
Well if the AFA has actuated because of a fire, as soon as you enter the building you are technically in a hazardous area and therefore in Offensive mode.
You could also say that you are not at a working incident if you are only looking for a fault and there is no sign of fire. I suppose that it would depend on the guidance given from each Fire and Rescue Service as to whether a tactical mode should be declared at AFA's.
Personally, I could always justify declaring an offensive mode at AFA's as I have known of a "FF's investigating" message to be sent back and the incident quickly escalated to 22 pumps and ended up a car park!
Brian - you cannot have an 'inactive mode' as a lot of my friends would declare this in relation to certain individuals at all incidents and this would cause confusion.
In Strathclyde they actaully pass a tactical mode in all messages, even AFAs, the basic pretence is that if you are the building investigating an AFA you're in the risk area where a firefighter could get injured, including simple things like falling on stairs etc and therefore you're DRA should suggest that you are in "offensive mode".
