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.
ACCESS TO SITE – Direct Public access to into the car park
Client Contact Details
Permits Issued By BCL / Permits Issued by Client
Yes
Information about the Work Site
Dive Vehicle Access – North of the village of Pewsey on the A345 Park in car park of the Waterfront public 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.

Diver,
The Diver reports to the Diving Supervisor. He is not only responsible for performance of his duties in a safe and professional manner but also for the wellbeing of his colleagues.
No action on his part should jeopardise either his own safety or that of those personnel associated with his work.
The Diver represents the Company while in employment with BCL and must conduct himself properly at all times. He must comply with safety requirements and confine any grievances, complaint or criticism to his immediate Supervisor, or BCL Project Manager.

A Stand-by Diver is a qualified diver whose role is to provide assistance to the diver or divers in the water in an emergency.
Consequently:
- He should know the emergency procedures.
- He should follow, from the beginning, the communications between the Diving Supervisor and the Divers.
- He must be ready to intervene immediately.
The Tender is answerable to the Dive Supervisor. He is responsible for all general duties involved with the operation other than those performed by specialist personnel.
It should be understood that the term Tender does not imply that a person designated as such is not a qualified diver nor does it mean that he can dive.
Site Hazard Summary (ACoP Ref 32b)
As per risk assessment, Tool Box Talk prior to operations to be performed, The Supervisor to access the area to ensure safe to operate. Canals and River Trust informed hazard locations are shown in Canals and River Trust Hazard plan located in Task Order Brief and Appendix A..
Intended Diving Methods (ACoP Ref 39)
Full surface supplied with communications.
Stand by diver in immediate state of readiness dressed in.
Suitability of Air Supply (ACoP Ref 46, 61 and 62)
The breathing medium for this diving operation will be compressed air.
The diver’s air supply will be supplied from the LP compressor and all the ancillary back up supplies as previously stated. The maximum anticipated depth will be no more than 10m.
The final delivery pressure will be monitored, by the Dive Supervisor, at the dive panel located at the Dive Control.
The standby diver will be supplied with an independent air supply to the working diver.
The diver’s gases will be constantly monitored for delivery pressure from the dive panel located in dive control.
Bail Outs
All divers will wear a ‘bailout’ cylinder charged with compressed air.
All bailouts will be fully charged, function tested and the contents reported to the Dive Supervisor.
The in water diver will be periodically requested to check their bailout pressures and report the reading to the Dive Supervisor to ensure that there is no leakage through the side block into the helmet.

4METHOD STATEMENT
Access and Site EnvironmentThe access and egress is via the dive Ladder, extreme care should be taken while accessing the project area
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 Methods
Carry 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)
The diver under the direction of the diving supervisor will inspect and carry out the following.
- The diver will swim the length of the area to be inspected looking for possible snags or trip hazards.
- The diver will inspect the determined area of wall 160m.
- A report will be compiled on the diver’s findings.
- At the end of each working day the helmets are to be disconnected from the umbilical’s and washed with fresh water
- On completion of the works all equipment is removed from site and the area is tidied and squared away.
- No rubbish is to be left and the site is to be left cleaner than when we arrived
Specialist Equipment Needs
Hand tools Only
Cement Mixer
Site Controls/Responsibilities
Diving supervisor is in overall control once diving operation underway
