Safety Advice at NDAC
Please ensure when you arrive on site you only park your vehicles
in the designated parking areas. The courtesy vehicles will shuttle
you and your kit down to the diving platforms. The shuttle service
runs throughout the day. No vehicles are permitted onto the turning
circle area at any time (except emergency services).
A kitting up
area has been constructed at the centre of the top car park. This
is where the courtesy vehicles will pick you up and return you when
you have finished your dive. We also provide trolleys to stop divers
struggling with their equipment, not only in the top car park, but
also at the drop off point at the turning circle. Can you please
ensure that ALL trolleys are put back where they came from. This
will help other divers moving kit from A to B.
We also provide
kitting up areas on the pontoons for your use. Can you please make
sure that ALL diving equipment is kept clear of walkways. This will
help other divers enjoy free movement on the pontoons.
We have invested
