Boiler Operator Training
NIFES offer a two-day on-site steam boiler operator’s course, specifically for boiler plant engineering staff.
NIFES have provided on-site boiler plant operators training courses for decades, the training ensures that the delegates are fully conversant with the latest documentation including the new standard BG01 – Guidance on the Safe Operation of Boilers which replaces Guidance note PM5: Automatically Controlled Steam and Hot Water Boilers.
If required, the training can also incorporate a critical review of Boiler Operating Procedures and accompanying Safety Rules and Procedures and can specifically present and discuss the general requirements for insurance inspections.
Typically, the courses are based on the following:
To raise delegates’ awareness and knowledge levels with respect to the technical principles of steam generation and the safe and efficient operation of boiler plant.
2-day classroom based at the clients site, although this can be rearranged to suit the particular requirements.
The proposed content is based on NIFES standard Boiler Operations training course and would be modified to suit the plant and operating conditions at the site. Particular reference will be made to the general requirements for insurance inspections on the site boiler plant.
