Vocational training standards require qualified mine instructors and trainers with safety expertise, instructional training, practical aptitude and refresher learning. Vocational Training Centres for coal, metalliferous and oil mines must engage instructors and trainers meeting prescribed qualifications, experience and instructional-training requirements. Mining instructors require relevant competency certification and mine-working experience, with below-ground centres requiring below-ground experience and unrestricted certification. Engineering qualifications or electrical supervisory certification apply to mechanical and electrical instruction. Mandatory instructional training covers training delivery, adult learning, assessment, record keeping, technical and regulatory awareness, hazard identification, risk assessment and personal protective equipment, followed by assessment and periodic refresher training. Trainers must possess operational safety knowledge, practical training aptitude and safety-mindedness.
