  • Why Process Safety Management Audits Fail

    Most companies have completed at least three process safety management(PSM) compliance audits of their covered facilities since the promulgation of the OSHA PSM standard. These companies, however, are not seeing noticeable improvements in their PSM programs. In fact, many companies feel that their PSM programs have become less effective. What has happened and why? Are there any lessons learned from the Enron collapse and its auditing program? What needs to be done?

  • Risk-Based Process Safety Design

    Safe design has long been a priority in the process industries. A safe design basis, together with a formal safety management system and safety practices, procedures, and training, is critical for providing that level of confidence required for risk management. The goal of process safety management is to consistently reduce risk to a level that can be tolerated by all concerned. A systematic, risk-based approach to safety design can help eliminate hazards that pose intolerable risk from the process and mitigate the potential consequences of hazards.

  • Understanding Regulated Health and Safety Standards--Part 1

    This paper provides the viewpoint of the American Conference of Governmental Industrial Hygienists (ACGIH), a private not-for-profit, non-governmental corporation open to all industrial hygienists or other occupational health and safety professionals. The authors have the opinion that there are misunderstandings about the use of regulated health and safety standards. In part one of this article, they provide some information on how regulations are formed and advice on using these values to conduct business. Employers and employees need this fundamental understanding to make informed health and safety decisions. This information is also useful for guiding public decisions about everyday toxic exposures.
