Children and Diving

By Guy Thomas from DAN Europe

Should We Treat Children as Small Adults When it Comes to Diving.

Depending on the dive training organisation or country, children can participate in introductory diving activities in a pool or suitable confined water starting from the age of eight. From ten, they can join “junior” diving courses. While this is not necessarily a problem, parents, doctors issuing fit-to-dive evaluation certificates, and dive instructors must consider several pertinent aspects before allowing young children to dive.

An important question is: does the child want to dive, or do the parents want their child to dive? Parental pressure is not uncommon. This is a red flag. It would be best if you never forced a child to undertake a diving course when they feel uncomfortable or obliged to participate. This makes for a very unsafe situation for all.

The child needs to be medically evaluated, and the doctor should be aware of at least the following considerations:

• Pulmonary development until the age of eight, where the diameter of the airways and lung elasticity are not fully developed.
• Higher pulmonary closing volume (the volume in the lung at which its smallest airways, the respiratory bronchioles, collapse).
• Functional immaturity of the Eustachian tube opening mechanism.
• Inner ear/sinus problems, are more prevalent in small children and can pose difficulties when diving.
• The presence of any cardio/respiratory or musculoskeletal system issues.
• Incomplete bone development.
• Unfavourable body surface to weight ratio, which increases the risk of hypothermia.
• Emotional maturity and ability to assess risks objectively. 

Finally, dive instructors need to evaluate the maturity of the child. The following questions are essential:

• Is the child capable of listening, understanding, following rules and interpreting hypothetical questions?
• Is the child capable of understanding mathematical and physical laws?
• Is the child capable of identifying and interpreting fear and reacting appropriately when stressed, scared or frustrated?
• Is the child capable of communicating problems, asking for help and offering help?
• Does the child possess the ability to self-care and care for others?
• Does the size of diving equipment present any issues concerning the size and form of the child?
• Is the child able to tolerate increased thermoregulation/metabolism? Understanding that a child will lose heat faster than an adult and may become hypothermic within a relatively short period is essential.
• Will the child comfortably enter and exit the water when fully equipped and manage any adverse dive conditions such as currents and wave swell? Children may not be physically capable of taking care of themselves or others in many aspects of safe diving.
• Will the child be able to handle the stress of the underwater environment, and are they comfortable in the water?

There is no specific psycho-technical test to assess a child’s overall ability to dive safely and comfortably. Consider the reaction of many children to distraction and concentration. A child may have a greater sense of adventure but a low-risk awareness. Children use concrete thinking and are less able to react adequately in situations different from those described by their instructors.

DIVING COURSES FOR & WITH CHILDREN | As a parent, you want to be confident that the knowledgeable and experienced when taking your child into the water; as a diving instructor, you want to ensure you have what is needed to do this safely.
Dive organisations have specific safety standards, but these mainly apply to adult course standards, with some restrictions (depth limits) and special requirements for the diving buddy. As a result, children will be learning from training materials produced for adults. Therefore, the instructor must explain certain concepts or have the tools to help explain these to the child and their parents.

Most dive organisations do not offer or require additional training from their instructors to dive with children. So the instructors need to understand the many considerations that apply to teaching children to dive. It is not only a diving depth limitation. Instructors should be aware of their responsibility and thoroughly inform themselves to mitigate all the risks. instructor is Diving equipment for adults might cause discomfort, difficulties, stress or even panic in a child. An adult small size BCD might be too big and result in the cylinder pulling the child to one side, which, in addition to a safety problem, will also ruin the fun. The instructor or dive centre needs to have child-sized equipment, which includes:

• Appropriate BCDs sizes.
• Child (low profile) masks are easier to clear when flooded.
• Smaller snorkels: Due to the dead space and potential for CO2 build-up in snorkels, the volume for children should not exceed 150 ml, whereas, for adults, the volume can be up to 230 ml.
• Fins with soft blades will give the needed propulsion but will help avoid leg cramps.
• A child-size diving suit: A child loses temperature faster, so the dive suit needs to have a good fit and an appropriate thickness.
• Lightweight regulators, with shorter hoses and smaller mouthpieces.
• Small/lightweight cylinder.
• Weight system: Consider using an integrated weight system to avoid the weight belt slipping off children’s smaller hips.

AFTER THE COURSE | Many of the same concerns as described above remain valid. The child’s dive buddy, which may be the parent, needs to understand the diving limits and plan dive trips to appropriate destinations, considering both the local diving conditions and the availability of the equipment that the child will need. They also need to be confident in caring for, assisting and even rescuing a child. Clearly, a child will not be able to participate in every type of diving and the buddy needs to be qualified, experienced for the type of dive planned, and physically fit.

To conclude, while we can say diving for children can be fun and safe, it is crucial to understand that everybody involved with training and diving must understand the limits and not simply consider children to be small adults.
