Why not? In other cases you might use a task entry instead of protected 
object.

What you did is a manual reset event. For your case a pulse event might 
work better:

    entry wait1 when OK is
    begin
       OK := False;
    end wait1;

If the pulse event to release several tasks it is a bit more 
complicated. An example is in the Simple Components.

Then there is usually task exit condition involved. So the pattern might be:

    entry wait1 when OK or else Exit_Requested is
    begin
       if Exit_Requested then
          raise End_Error;
       else
          OK := False;
       end if;
    end wait1;
