This is our procedure, also same with SAA
Our Briefing clearly says , part of it
==============
CAPT: If we have a fire related problem on the ground, I will position the a/c with the problem area downwind and set the park brake and advise the cabin crew to sby,
we will asssess the problem and you will ACTION THE RECALL ITEMS ON MY COMMAND,
we will re-assess the situation and if an evacution is required , my actions will be PARK BRAKE SET , SPEED BRAKE LEVER down detent , START LEVERS cut-off, EVACUATION Initiate, FIRE WARNING switches override,pull , and ROTATE if there is fire
simultaneously yours actions will be ?
F/O: Flap lever to 40, Sby power switch to Battery, Pressurization mode selector to manual DC, outflow valve open and notify tower on vhf1
==========
ROTATE IF THERE IS FIRE , this used to be just rotate it irrespectively but now unless there is fire , no need to rotate
So in my company its the captain doing it !
