I guess they do actually mean "evacuate everyone to a position upwind at least 18m from the aeroplane" but, that is only part of the issue. What about the adjacent jet that is downwind and boarding pax from busses etc in a possible scenario? The toxic gases are extremely nasty. what is the safety recommendation for evacuating downwind of a battery event? BTW, anyone within the safety distance must wear positive pressure breathing equipment so, all those guys staring at the "event" are in the wrong place!
