Definitions
Enterprise means an organisation where training and/or assessment is taking place,
and/or where the trainee is employed.
Enterprise procedure is defined as actions which comply with the policies, systems,
and directives in a particular enterprise. Enterprise procedure must comply with the
requirements of the Health and Safety in Employment Act 1992, and subsequent
