 It is important for trainers to tailor the OSHA guidelines to their specific work site so that the training is relevant to the specific working conditions and not just a long generalized informational session.Many standards promulgated by OSHA explicitly require the employer to train employees in the safety and health aspects of their jobs.Other OSHA standards make it the employer's responsibility to limit certain job assignments to employees who are "certified," "competent," or "qualified"—meaning that they have had special previous training, in or out of the workplace.
