Written Scheme

The duty holder should prepare and monitor any existing Written Scheme for preventing and controlling the risk. The Written Scheme gives an overview of responsibilities for tasks forming the basis of a Written Scheme. Estate Management recognises each Department shall have a different “Written Scheme” due to the differing installed assets.

The document Water Safety Procedures including Written Scheme should be referred to when determining the “Written Scheme” for an individual Department.

The “Written Scheme” may change as modifications are made to the systems. The “Written Scheme” is to be updated when these modifications are made.

The written scheme should include, where appropriate, and with reference to the risk assessment:

(a) an up-to-date plan showing the layout of the plant or water system, including parts temporarily out of use (a schematic diagram is sufficient);

(b) a description of the correct and safe operation of the system;

(c) the precautions to take;

(d) checks to carry out to ensure the written scheme is effective and the frequency of such checks;

(e) the remedial action to take if the written scheme is shown to be not effective.
