Medical Statement for Participation in Scuba Diving Activities - Participant Record (Confidential Information)

This is a statement in which you are informed of some potential risks involved in scuba diving and of the conduct required of you during the scuba-training program. Your signature on this statement is required for you to participate in the scuba-training program offered by the above-named Dive Centre.

Read and discuss this statement prior to signing it. You must complete this Medical Statement, which includes the medical-history section, to enrol in the scuba-training program. If you are a minor, you must have this statement signed by a parent.

Diving is an exciting and demanding activity. When performed correctly, applying correct techniques, it is very safe. When established safety procedures are not followed, however, there are dangers. To scuba dive safely, you must not be extremely overweight or out of condition. Diving can be strenuous under certain conditions. Your respiratory and circulatory systems must be in good health. All body air spaces must be normal and healthy. A person with heart trouble, a current cold or congestion, epilepsy, asthma, a severe medical problem or who is under the influence of alcohol or drugs should not dive. If taking medication, consult your doctor and the Instructor before participation in this program. You will also need to learn from the Instructor the important safety rules regarding breathing and equalization while scuba diving. Improper use of scuba equipment can result in serious injury. To use it safely, you must be thoroughly instructed in its use under direct supervision of a qualified Instructor.

If you have any additional questions regarding this Medical Statement or the Medical History section, review them with your Instructor before signing.

The purpose of this medical questionnaire is to find out if your doctor should examine you before participating in recreational diver training. A positive response to a question does not necessarily disqualify you from diving. A positive response means that there is a pre-existing condition that may affect your safety while diving and you must seek the advice of your physician. Please answer the following questions on your past or present medical history with a NO or a YES. If you are not sure, answer YES. If any of these items apply to you, we must request that you consult with a physician prior to participating in scuba diving.

Safe Diving Practices Statement for Poseidon MKVI Rebreather

Please read carefully before signing.

This is a statement in which you are informed of the established safe diving practices for skin and scuba diving. These practices have been compiled for your review and acknowledgement and are intended to increase your comfort and safety in diving. Your electronic signature now, and physical signature before the start of the course, on this statement is required as proof that you are aware of these safe diving practices. Read and discuss the statement prior to signing it. If you are a minor, this form must also be signed by a parent or guardian.

By my initials and signature on this document, I,

Required Your name

, evidence that I have fully read, contemplated, and understand the contents of this Statement.

Maintain good mental and physical fitness for diving. Avoid being under the influence of alcohol or dangerous drugs when diving. Keep proficient in diving skills, striving to increase them through continuing education and reviewing them in controlled conditions after a period of diving inactivity, and refer to your course materials to stay current and refresh yourself on important information.

Be familiar with your dive sites. If not, obtain a formal diving orientation from a knowledgeable, local source. If diving conditions are worse than those in which you are experienced, postpone diving or select an alternate site with better conditions. Engage only in diving activities consistent with your training and experience. Do not engage in cave or technical diving unless specifically trained to do so.

Use complete, well-maintained, reliable equipment with which you are familiar; and inspect it for correct fit and function prior to each dive. Follow equipment and procedural checklists, and do not dive if there is a possible fault or you feel uncomfortable about the dive. Maintain equipment and follow manufacturer's guidelines for service and maintenance. Monitor and replace consumable products and use only manufacturer's recommended replacements. Deny use of your equipment to uncertified divers. During all open water training dives, each student diver, Certified Assistant and Instructor must be equipped with: fins, mask and snorkel; compressed gas cylinder and valve; buoyancy control device (BCD) (with tank mount or separate backpack) and low pressure inflator; regulator and alternate air source; submersible pressure gauge (in addition to a computer-integrated monitoring device); depth gauge (or other monitoring device e.g. diving computer); weight system and weights (if necessary for neutral buoyancy); adequate exposure protection appropriate for local diving conditions; at least one audible emergency surface signaling device (whistle, air horn, etc.); timing device (or other monitoring device e.g. diving computer); compass; knife/diver’s tool/cutting device (except where prohibited by law or local regulations). This is considered the minimum equipment for recreational dives after you are certified. Instructors and Certified Assistants must also be equipped with: two surface signaling devices – one audible (whistle, air horn, etc.) and one visible (inflatable surface tube, flare, signal mirror, etc.); a dive flag where required by local law (consider using a surface support station with a dive flag); access to a first aid kit at the dive site; access to oxygen at the dive site.

Listen carefully to dive briefings and directions and respect the advice of those supervising your diving activities. Recognise that additional training is recommended for participation in specialty diving activities, in other geographic areas and after periods of inactivity that exceed six months.

Adhere to the buddy system throughout every dive. Plan dives with your buddy, including communications, procedures for reuniting in case of separation and emergency procedures.

Be proficient in dive table usage. Make all dives no decompression dives and allow a margin of safety. Have a means to monitor depth and time underwater. Limit maximum depth to your level of training and experience. Slowly ascend from every dive at the rate prescribed by the manufacturer of your equipment, or in the absence of any guidelines, at a rate of not more than 9 metres/30 feet per minute. Follow any computer-required stops. Make a safety stop as an added precaution, usually at 5 metres/15 feet for three minutes or longer.

Maintain proper buoyancy. Adjust weighting at the surface for neutral buoyancy with no air in your buoyancy control device. Maintain neutral buoyancy while underwater. Be buoyant for surface swimming and resting. Have weights clear for easy removal, and establish buoyancy when in distress while diving.

Breathe properly for diving. Never breath-hold or skip-breathe when breathing compressed air, and avoid excessive hyperventilation when breath-hold diving. Avoid overexertion while in and underwater and dive within your limitations.

In addition, if diving on a rebreather, monitor and obey the unit’s alarm systems. If the mouthpiece vibrates, then change the switch position. If you hear the alarm, then switch to open-circuit immediately. If the HUD light flashes, then look at the LCD screen on the electronic Primary Display. Monitor and know your partial pressure of oxygen (PPO2) at all times to ensure it remains within the manufacturer’s recommended limits. Monitor all other information provided by the Primary Display, and act on it. When feeling unwell or abnormal underwater, or if in doubt, bail out - switch to open-circuit and ascend under control to the surface. Minimise flooding of the breathing loop, by retaining the regulator in your mouth when on closed-circuit, maintaining a seal around the mouthpiece, and switching to open-circuit before removing the mouthpiece underwater or on the surface. Plan successive multiple dives on the same unit and same battery. Monitor your CO2 absorbent and allowable dive time.

Use a boat, float or other surface support station, whenever feasible.

Know and obey local dive laws and regulations, including fish and game and dive flag laws.
