Along with the element of employee participation, contractors must be included. These embedded workers are as critical as direct employees. In many cases the use of contractors for maintenance activities has led to limited direct employee usage. Think about all the activities in which hazards in the worksite are being analyzed. Are contractors involved with JSAs, HAZOPs and LOTOs? A key piece of information may be missing if they are not! Remember, every time a change occurs in the plant, the knowledge of the prior people who are in maintenance has been changed. Therefore contract personnel may have important information to help you be successful.
