How to use a Ringbuoy
Specification for Ringbuoy and Guidelines for its erection
The ringbuoy is used as a quoit and line and is not designed to support a person with positive buoyancy similar to a SOLAS Approved Life Belt, which is 36" diameter.
Weight of ringbuoy: 1kg Polyurethane foam filled
Positive Buoyancy of a Ringbuoy: a minimum of 50 Newton's
18" is the maximum that the Ring Buoy should achieve in diameter.
25 meters of rope for most cases however up to a maximum of 30 meters at bridges in tidal estuaries. (Length of rope should be Air Draft of bridge at MLWS plus ten Meters where possible)
MLWS: Mean Low Water Spring. The mean low water spring is the lowest level to which spring tides retreat on the average over a period of time.
.5 tonne breaking strain, 8 plaid, 6mm coloured red and yellow polypropylene. This line should be attached to the ringbuoy by means of a bowline knot.
A galvanised box steel crucifix or galvanised pole is recommended for their erection.
Dimensions 5mm box steel - galvanised with a 25mm by 5mm base plate used for securing to stone or concrete with 4 bolts. Overall length 180mm, transverse length 41mm - 20mm from the top.
3" galvanised steel pipe with a plastic blank on the top to waterproof it internally. To improve their visibility PVC pole covers should be used in the red and yellow colours.
Alternatively the boxes can be bolted directlyto walls, the bottom of the box should be approximately 1300mm from the ground.
The Ringbuoy should be erected in the yellow box with the sticker " A stolen ringbuoy - a stolen life "on the front of the box. This sticker has proved most successful at reducing the degree of vandalism and interference to the ringbuoys.
The rope should always be coiled in a clockwise direction free of kinks and knots, then stowed at the bottom of the Box.
The Boxes should be erected approximately 100 Meters apart or within sight of the next (i.e. avoid blind erection spots - people should always be able to see one in an urban area at any stage along the river/canal/pond/lake edge)
The Ringbuoy should be positioned above the Mean High Water Spring line if it is a tidal waterway or above the Winter Flood line on a river or lake. This is to ensure safe access to it at all times. It should be located in a conspicuous position in close proximity to the waterway so as to allow easy access to it.
To effect a rescue with a ringbuoy the rescuer should aim the ringbuoy to fall a short distance beyond the casualty so that it can be retrieved towards them. When the casualty has a firm grip they are retrieved slowly to the bank or edge. It is essential that the rescuer reassures and instructs the casualty throughout the rescue to ensure their co-operation and confidence.
