Foreword
This Program Outline is issued by the Industry Training and Apprenticeship Commission for use in apprenticeship training classes sponsored by the Industry Training and Apprenticeship Commission. Indentured apprentices will be directed to the Apprenticeship Training classes in accordance with the General Regulations made pursuant to the “Industry Training and Apprenticeship Act” of British Columbia.
It is intended as a guide for instructors of apprenticeships. Practical instruction by demonstration and student participation should be integrated with classroom sessions. Safe working practices, even though not always specified in each operation or topic, are an implied part of the program and should be stressed throughout the apprenticeship. It is the responsibility of employers to ensure safety training for the apprentice working on their worksite.
The “Content” portion of each competency is there as a guide only, and is not intended to be exhaustive.
A ‘Glossary’ of verbs is included at the end of the Program Outline. It is there to clarify the intent of the “Learning Objective” and “Learning Task” statements. Also included at the end of the Program Outline, is a Competency Profile chart and a list of Tools and Equipment necessary to offer the training.
The Program Outline was prepared with the advice and assistance of representatives of management and labour and in cooperation with the Industry Training and Apprenticeship Commission.
SAFETYADVISORYBe advised that references to the WorkSafe BC safety regulations contained within these materials do not/may not reflect the most recent Occupational Health and Safety Regulation (the current Standards and Regulation in BC can be obtained on the following website: http://www.worksafebc.com. Please note that it is always the responsibility of any person using these materials to inform him/herself about the Occupational Health and Safety Regulation pertaining to his/her work.
