General Information and Instructions

On arrival at the centre, please ensure you complete a Visitor’s Declaration Form in the shop or on the gate Download PDF 792KB or visit the downloads page more>. The white customer copy must be displayed in full so all details are visible from your vehicle dashboard at all times. NDAC club members must display their cark park passes in the same way.

Please make sure you read and understand the information about the centre and the depth of the water, which is displayed, on notice boards around the centre. Staff will be more than happy to help clarify any points.

You must be no younger than 10 years old to dive at the NDAC. All junior participants must be closely supervised by adults at all times and never left unsupervised.

The NDAC dive plan / risk assessment is available from the shop. You are encouraged to consult this document and always to dive fully in accordance with the safe diving practices of your recreational diving agency (e.g. PADI, BS-AC, SAA, TDI/PSI etc.).

Always dive within your qualification level.

Divers are requested to plan their dives carefully. The diving site is 60metres above sea level. Can all divers take this into consideration and dive according to any impact it may make to your dive plan from your training organisation i.e. PADI, BSAC, SAA etc.

Solo diving is not permitted. If you become separated from your buddy ascend without delay and notify an NDAC member of staff with immediate effect.

Do not dive below 50meters on Air or Nitrox.

Do not dive below 30 meters without a torch.

Do not dive without a whistle.

Do not dive below 30 meters without wearing adequate thermal protection.

Use a pony or other reserve cylinder below 30 meters.

Yellows SMBs should only be used in emergencies.

Warning notices are displayed throughout the site and suitable lifebuoys and lines are provided at the waters edge or on the pontoons or in the safety boat.

No vehicle movements will be permitted past the turn-round point while the centre is open to the public (except for emergency and NDAC vehicles).

Underwater training platforms (see site map) are provided for training purposes. Non trainees should be aware that students are using these areas and may wish to plan dives avoiding such areas at busy times (weekends).

A number of underwater attractions have been provided at the NDAC (please refer to underwater map or the attractions page for more info). Divers enter or otherwise interact with the attractions at their own risk.

Diving in cold water has resulted in many preventable incidents at freshwater sites due to regulator freezing and divers wearing inadequate thermal protection. The daily water temperature is available on the site map, internet, or from a member of staff. Note that the water is likely to be several degrees colder at depth than it is in the shallows. Please refer to your owner’s handbook for information on using your equipment in cold water. Please also observe recognised safe diving practices that will minimise the risk of regulator free-flows and maximise the adequacy of your response should a free-flow occur.

Notices will be published throughout the site when the centre is being used for activities other than diving. Certain areas of the quarry may be put Out Of Bounds (OOB) to divers while activities are being conducted.

Do not dive outside the displayed opening times.

Speak to any of the centre staff if you are unsure about anything on the site.

Emergency Arrangements at NDAC

First-aid, rescue and emergency procedures have been put in place at the NDAC. The Centre staff will make every effort to respond as quickly as they can to any emergency on the site both in and out of the water. In the event of an accident alert the staff immediately. We also conduct emergency rescue and casualty evacuation drills periodically to test the effectiveness of our arrangements. Any incidents or dangerous occurrences WILL be reported to the relevant enforcing authority in accordance with our statutory duties.

If you see anyone underwater with a problem wherever possible, help them to the surface and raise the alarm at once by blowing a whistle, shouting and waving.

At the waters edge if you see anyone in trouble, raise the alarm at once by blowing a whistle, shouting and waving. While someone else alerts the centre staff, stay where you are, monitoring the person in the water until the person in trouble has been reached. Please then follow directions given by the centre staff.

DO NOT RUN, OR BLOW WHISTLES unless there is an emergency.

Do not litter the site

Environmental Issues

To maintain water quality and prevent potential health hazards can ALL divers and members of the public use the toilet facilities provided on site. This will prevent potential harmful contamination of to the water.

Theoretically Weil’s disease (Leptospirosis) can be a hazard at any inland freshwater site. The NDAC has never known anyone to contract the condition, but information cards on the subject are available free of charge from the shop or visit the Leptospirosis Information site. more>

Do not harm any wildlife on site, or damage any property above or below the water.

Do not litter the site. Dispose of litter in the bins provided.

Gas Room

Charging of Cylinders

The Gas & Cylinder Charging Station (Gas Room) is out of bounds to ALL members of the public.

NDAC staff will check ALL cylinders before filling to ensure there are no obvious defects.

Pressure checks will be carried out and test stamps will also be checked.

The centre reserves the right not to fill any cylinder it deems suspect.

ALL divers requiring specific technical fills are to ensure they produce the correct paperwork. Mixed gas will not be blended without sight of your cert card or associated affiliation cards (no qualification no fill!). On completion of the fill you will be required to sign a log verifying that you have received your requested gas mixture.

Surface 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 in a state of the art gas room. Fills are done on a first-come first-served basis. At busy times you may be required to wait for you fills. Our staff will give you an estimate of how long you may have to wait. Please be patient.

NDAC Ltd or its appointed staff cannot accept liability for your personal equipment and effects. If any equipment is found above or below the water we operate an honesty box that is situated inside the shop.

For safety reasons barbecues are not permitted at NDAC. We do offer an extensive range of hot and cold food from out catering unit located at the top car park.
