Trade secrets is one of the 14 elements of the Occupational Safety and Health Administration (OSHA) Process Safety Management (PSM) standard. However, unlike the other 13 elements, there is little explanation or guidance on how to comply with this element, which may occur to be a problem for implementation in the process industries. As of the past decade, problems relating with trade secrets have emerged. Thus, the purpose of this paper is to present a structured and easy technique to plan and implement Trade Secret as per PSM requirements. A work-aid tool in the form of a database model was developed, guiding employers to comply with the trade secret element. This technique has the potential to help users to manage trade secret better and to reduce adverse impacts to people, environment and assets. © 2016 The Authors.
