Who is it for?
This course is designed for practicing boiler house operatives or those responsible for managing a boiler house and its operators.
What is BOAS?
The Boiler Operation Accreditation Scheme (BOAS) provides national accreditation for industrial boiler operators and boiler plant managers. The BG01 guidelines suggest that all competent persons and owners/managers should be trained to the BOAS standard.
Spirax Sarco is a licensed and approved BOAS training provider. The D6A course provides training to the BOAS syllabus and includes the written examination [2]. Candidates are also interviewed by a third party (KIWA-Gastec) assessor during the course [3].
Successful candidates may use the designatory letters "Cert IBO" (Certified Industrial Boiler Operator) or "Dip BOM" (Diploma in Boiler Plant Operation Management). Candidates from both award categories take the same course and written papers [4]. Interviews are specific to each award.
Delegates taking the Cert IBO and Dip BOM will achieve Dual Award status.
All awards are valid for five years, after which a renewal course becomes necessary [5]. 
Course Objectives
