Tank upright, BCD tank band straps are loosened as to allow easy placement of strap around the tank. NOTE: Hard pack BCD’s usually have ONE tank band, Soft pack BCD’s usually have TWO tank bands. Most bands have a buckle / cam strap and need to be weaved a particular way to stay secured. Ensure the BCD’s placement on the tank so the tank valve is level with where the diver’s neck will be and that the front part of the valve (where the air is released) is facing the back of the diver. Secure the strap or straps so they are tight enough to pick up the BCD and tank and not slip while shaking. Regulator placement: The First stage (dust cap removed) is placed over the tank valve so the intake of the 1st stage covers the o-ring on the tank valve, (o-ring should be in place – if not, lack of seal will cause air leak).

  • Buddy Board System for Swimming Areas
    Children’s Camps Buddy/Board Systems Contents Buddy/Board System Components Swimming assessments Swimming areas Buddy system Board system or equivalent accountability system Public Health Hazards Safety Plan Swimming Assessments • Assessment of swimming abilities for each camper (also recommended for staff) – Determined by a progressive swim instructor (PSI) – Conducted annually and as appropriate – Campers considered non-swimmers until determined otherwise by PSI • Minimum of two bather classifications: – Non-swimmer and swimmer • See DOH Fact Sheet titled Progressive Swimming Instructor for NYS Children's Camps for approved PSI certifications • Annual assessments are needed - camper’s swimming abilities may change from year to year due to injures and/or changes in fitness or physical abilities. • Reassessment needed to advance to the next level. • Assessment should be appropriate for the type of facility (i.e., pool, lake). Swimming Assessments • Assessment criteria is not specified in Subpart 7-2 • ARC Camp Aquatic Director Training Module suggested criteria for “Swimmers”: – Ability to swim 50 yards using a minimum of two strokes – Change direction while swimming include prone & supine positions – Ability to follow directions of lifeguards No standard/code required assessment criteria. Based on their training, a PSI uses swimming criteria for instruction, which does not necessarily correspond to “Swimmer” and “Non- swimmer” categories. Assessment criteria and categories must be specified in the safety plan and identify which level is equivalent to a non-swimmer. The ARC Camp Aquatic Training Module is no longer available. It was developed in 2001 in a collaborative effort between the American Red Cross (ARC), the NYSDOH and the camping industry.

  • Diving Skills Diving Skills
    Diving Skills Diving Skills Before beginning your open water practical skills training, in a safe, shallow water area you should practice your skills. It is important to have self-confidence in your abilities before beginning open water practical skills training. 11 Diving Skills Donning Snorkel Set ［Mask］ First, we need to de-fog our mask. Then we need to tie up any loose hair so it doesn’t enter the mask, breaking the seal. After fitting to the De-fog face, pull the straps around the back of the head and adjust the tension. Be Careful of Your Hair ［Fin］ While your buddy helps support your balance, you hold one fin in which to place your foot while gripping the other empty fin. Once your foot is sufficiently in the pocket, pull tight the strap (of an open heel pocket fin). If you are using the full foot pocket type, carefully fold up the heel. Cooperating With Your Buddy 11 Diving Skills Snorkel Clear Ballast Method To clear your snorkel there is the ballast method and the displacement method. The ballast method involves inhaling a large breath at the surface and blowing strongly into the snorkel. The displacement method involves using the remaining air in the snorkel to blow out while keeping your head up. Either method will allow you to clear your snorkel easily. Displacement Method Fin Work While slightly bending the legs, we slowly and in a large cycle kick with our whole legs. With this method we can gain suitable propulsive power. The dolphin kick can be achieved by joining your legs together and moving them in unison, much as a dolphin does.
