Compressor Operation
AIM
To instruct members in the safe and correct procedures for operating a high pressure air compressor; for filling cylinders from a compressor and from an air storage bank; and for good compressor management.
DURATION
One day. See Note 1.
ENTRY GRADE
Open to all.
INSTRUCTORS
Chief Instructor to be a BSAC Instructor of proven knowledge and ability in the subject. Professional engineering qualification desirable. Assistant Instructors to the satisfaction of the Chief Instructor. One instructor for every eight students.
FACILITIES
A suitable classroom. Use of high pressure air compressor(s) and air storage bank if possible. Availability of Air Purity testing apparatus is very desirable
APPROVAL
Course Approval Procedure applies.
QUALIFICATION
Course Certification will be issued.
SYLLABUS
Instructor briefing
Assemble, Introductions, Administration
1. Classroom Lesson Theory and design of Air Compressors (60 mins)
5. Classroom Lesson Cylinder filling (30 mins)
These two activities be can run concurrently. Both must be supervised by an experienced instructor at all times.
7. Classroom Open Forum
NOTES
1. The order in which the syllabus is listed represents the recommended sequence for the course. It may alternatively be spread over a series of shorter (evening class) lessons if desired, in which case all theory lessons should be covered before practical experience is gained.
2. Students are asked to bring empty aqualung cylinders for filling.
