You first have to determine if a situation can be solved using training. Training, or retraining as the case may be, could be required by an OSHA standard. Training is an effective solution to problems such as employee lack of understanding, unfamiliarity with equipment, incorrect execution of a task, lack of attention, or lack of motivation. Sometimes, however, the situation cannot be mitigated through the use of training and other methods, such as the establishment of engineering controls, may be needed to ensure worker safety.
