MAINTENANCE, REPAIR AND MODIFICATION
9.1 Maintenance Boiler systems must be properly maintained and in good repair, so as to prevent danger, and must take account of manufacturers’ instructions in accordance with PSSR Regulation 12 and PUWER Regulation 5. All maintenance requirements and activities shall be fully documented, including the frequency that maintenance should take place, and maintenance logs must be kept up to date. 9.2 Modification & repairs Prior to any changes or modifications, a risk assessment should be undertaken, and the effects of any modifications, repairs or adjustments to the pressure equipment must be assessed by the CP to determine whether a review of the WSE will be required; this assessment shall take place prior to the work being undertaken. The WSE itself must be reviewed at appropriate intervals (PSSR Reg 8) and it is recommended it is reviewed by the CP at each examination (PSSR ACoP para 117). Modifications and repairs to pressure systems must comply with PSSR Regulation 13. For significant repairs, the following points must be addressed: x All alterations to the boiler must be documented and reports or records kept for the life of the boiler; x Repairs and modifications may in and of themselves only address the symptom. The underlying causal factors which necessitated the repairs or modification must themselves also be addressed; x Design of the repair must make reference to the original design code and other suitable guidance and achieve an equivalent standard; x Materials must be suitable and closely match the properties of the original equipment; x Workmanship must be in accordance with suitable standards including non- destructive examination where applicable; x Significant repairs or modifications to boiler systems, changes in their operating pressure or changes in cyclic operation must be notified to the CP, the WSE reviewed and the system thoroughly examined prior to coming back into use; x Any alterations to the original specification of either the boiler system or the boiler house will require consideration and approval by the manufacturer and CP/s before instigating; x Steam and hot water leaks are dangerous and will waste energy. Identified leaks should be cordoned off and repaired as soon as practicable; x It may be necessary to carry out modifications or repairs to the burner control and alarm systems. Significant modifications and repairs, where they affect integrity and/or safety of the system, its controls & software, shall be properly considered and the CP shall be kept fully informed of proposals. Modifications to shell boiler installations may not directly affect the pressure envelope but could be just as significant. For example, MCP users/owners may find that the emissions limits in the MCPD are quite onerous for certain fuels and a change of fuel is proposed.
