The user/owner of the boiler is responsible for complying with the following requirements of PSSR: x Safe Operating Limits (SOL) have been set and are not adjusted without informing the Competent Person (CP) and manufacturer where appropriate; x The system is never operated unless a current Written Scheme of Examination (WSE) is in place. Any requirements of this scheme e.g. a report of the last examination, must also be satisfied (Regulations 8 & 9); x The items identified in the WSE must be examined by a CP in accordance with the requirements of the scheme; x The results of all tests and examinations must be recorded by the CP (Reg 9) and retained by the user/owner for a suitable period (see Log Sheets, Appendix 4). A period of at least two years is recommended for retention of records of routine tests (see section 8); x All repairs and modifications shall be carried out by people suitably competent in such work (Regulation 13, PSSR, ACoP Para 176). You must discuss and agree any changes with the “Competent Person” and include any changes within your written scheme of examination (WSE) (ACoP Para 116,117). The details of such work shall be retained for the life of the plant; x The statutory technical documentation and other records must be kept and where required, be made available for examination. All records may be kept on-site or at a designated central location but wherever they are kept, they must be secure and easily accessible, and records must be transferred when the ownership of a system changes (Regulation14, PSSR). The user must give operational employees adequate instruction so that the boiler can be operated safely (Reg 11 and para 145 ACoP). For a steam boiler these should include (paras 151 & 152) instructions covering: x pre-firing and start-up instructions; x feed water treatment; (see BG04) x safe blowdown of the boiler (see BG03); x precautions to be taken when emptying the boiler; x precautions to ensure positive isolation and depressurisation of one boiler from a common header and blowdown system if internal access is required; x precautions to be taken before carrying out maintenance operations; x procedures to be followed in the event of a shortage of water, bursting of tubes or other event requiring the boiler to be shut down. Temporary Boiler Plant: Companies who hire out steam boilers are usually hiring out a pressure system. Para 39 of the PSSR ACoP says that a steam boiler [fitted with skids] may be installed temporarily to maintain steam supply to the site during the replacement of an existing boiler, but such an installation should not be treated as a mobile system. So mobile steam boilers are not in fact mobile plant for the purposes of PSSR, and where a person supplies an installed system by way of lease or hire, and agrees in writing to be responsible for discharging the duties of the user, all the provisions of regulations 8(1) and (2), 9(1), 11(1), 12 and 14 must be followed (Reg3(5)) and the requirements of PSSR Schedule 2 must be followed. CEA BG08 Guidance on Temporary Steam and Hot Water Boiler Plant contains detailed information regarding the safe use of temporary boiler plant.
