8.2 Competence and training
The necessary OSH competence requirements should be defined by the employer, and arrangements established and maintained to ensure that all persons are competent to carry out the safety and health aspects of their duties and responsibilities. The employer should have, or should have access to, sufficient OSH competence to identify and eliminate or control work-related hazards and risks, and to implement the OSH-MS. To this end, training programmes should cover all members of the organization, as appropriate, be conducted by competent persons, provide effective and timely initial and refresher training at appropriate intervals, include participants' evaluation of their comprehension and retention of the training, and be reviewed periodically. The review should include the safety and health committee, where it exists, and the training programmes, modified as necessary to ensure their relevance and effectiveness. They should be documented, as appropriate and according to the size and nature of activity of the organization. Training should be provided to all participants at no cost and should take place during working hours, if possible. Occupational safety and health management system documentation should be established and maintained, and may cover the OSH policy and objectives of the organization, the allocated key OSH management roles and responsibilities for the implementation of the OSH-MS, and the significant OSH hazards/risks arising from the organization's activities. It should also include arrangements for their prevention and control, and arrangements, procedures, instructions or other internal documents used within the framework of the OSH management system. The documentation should be periodically reviewed, revised as necessary, communicated and readily accessible to all appropriate or affected members of the organization.
