1. e oo 6 2 DIVING IN COLD WATER Cold water diving is dangerous and requires special planning and preparation Below is a summary of some effects of cold water on the components of the DIVATOR system 6 2 1 Regulator Unit Internal freezing The first stage regulator reduces the cylinder pressure to approximately 8 bar 116 psi The air expands the pressure falls and the temperature will drop considerably If the air contains moisture ice crystals will form that may obstruct the supply of air Internal freezing of this kind can cause a total air stoppage Dry clean air should therefore always be used See the Cylinder Filling section for air quality requirements If the water and or air temperature 15 low and the anti freeze cover assembly of the regulator 15 damaged this in combination with the cooling that will occur with the pressure reduction in the regulator could cause freezing If that happens water enters and solid will form in the spring housing of the regulator and the regulator mechanism will stick 1n open position The secondary pressure will then rise above normal and open the safety valve in the breathing valve The excess air will then flow through the face mask mouthpiece and out into the water In order to avoid this the a

TING JACKET BCJ The Interspiro BCJ stabilizing jacket design features flexible buoyancy control The stabilizing jacket uses unrestricted internal channels that allow air to constantly flow throughout the jacket accumulating at the highest point The diver is surrounded by the bubble of air flow and can move easily and precisely At the surface the stabilizing jacket provides the diver with a comfortable fit floating ease and the ability to be in the face up position The BCJ is CBRD certified as a Combined Buoyancy and Rescue Device because of its lift capacity and face up body positioning at the water s surface The BCJ includes a 3 dump deflation system that enables divers to dump air three different ways From the right shoulder equipped with a lanyard handle From the left shoulder integrated into the corrugated hose From the waist for divers in head down position BCJ jackets require a minimum internal volume to allow enough air to be injected in order to reach neutral buoyancy as needed This produces the necessary lift for the ascent to and flotation on the water s surface European Union norms require a minimum lift capacity in relation to the size of the tank used as measured in kilograms In order to increase safety the BCJ 1s equipped with an extra inflation air source cylinder of 0 47 1 200 bar The BCJ contains a durable double bladder design with a tough polyurethane inner bag that is protected by an 840
