No
That is why the bl00dy things are painted on the tarmac, to prevent this kind of accident.
Same as guidance lines and parking bays for fixed wing aircraft. They are there for a reason.
Regardless of what is painted on the tarmac (the area could be contaminated with oil/fuel etc) the accident was still very preventable if you don't land too close to the other aircraft.
This is a little 2-pad heliport not an international airport.
If you are expecting to launch immediately and the other aircraft isn't expected back until later then why be pedantic and take more time over exact positioning of the aircraft?
The failure to leave enough clearance by the pilot of the landing aircraft is the overriding cause of this accident - the other bits are additional holes in the swiss cheese.
