Site Hazards Identified By Canals and River Trust

DIVER ENTRAPMENT - Underwater obstructions may be present at the dive site including sluice door and chamber

UNDERWATER OBSTRUCTION(S) - If underwater obstruction(s) are found they will be identified and if possible removed to a safe place, if they cannot be removed easily the size and dimensions will be recorded and the dive plan altered so the diver will not become snagged up in any way.

ACCESS TO THE WATER – Is via slipway or folding ladder from towpath.

MOORED BOATS – All staff to be on there best behaviour language to be controlled noise kept to a minimum.

LOW VISIBILITY - Underwater visibility is likely to be poor

BIOLOGICAL CONTAMINATION - Leptospirosis and other waterborne pathogens may be present. Contaminated sharps may also be present at the site. Full dry suits and gloves are to be worn by divers. Barrier cream and hot water washing facilities will be available in the welfare van.

BOATING ACTIVITY – Navigation will be open, Leisure vessels use this site. All staff to keep a good lookout for vessel movements.

DEBRIS - Debris may be present on or below the water surface.

House. Nearest Post Code is: SN9 5NT.

Diver Access – will be by towpath wall and ladder freeboard less than 0.5m

Remember a fully kitted diver must not climb ladders over 2.0m and generally freeboard up to 0.5m is accepted suitable for manual recovery of an unconscious diver. Freeboard over 0.5m will require a means of mechanical assistance for the recovery of an unconscious diver.

The Complete Air Diving system will set up next to the work site adjacent to the access and egress point, once installed, the equipment will be inspected and tested in accordance with HSE regulations” for the preceding operation.

The area allocated for this purpose is to be sectioned off and all personnel are to be advised of diving operations.

The diver will familiarise himself on surface with the location of the work site in particular in relation to diver entry point into the water.

The diver will be deployed to the work site. The divers swim route to the work site should be defined so that his access route shall be as straight as necessary to avoid obstructions, where practicable. Where the area is bleak, warm weather gear to be worn with gloves.

Work MethodsCarry out Toolbox talk, as discussed and referred to this RAMS and associated Risk Assessment

Once the Diving Supervisor has confirmed all systems are functioning satisfactorily he will instruct the diver to enter the water via the ladder.

After the diver enters the water and on reaching the bottom, the supervisor will take a Pneumo reading to establish the diver’s depth and record it in the dive log (this will be continually checked by the Supervisor during the dive)
