Case study research has found that the presence of an OHSMS is insufficient to prevent ill-health, injuries and fatalities.
The safety culture approach to OHS has been part of the research around OHSMS but addresses the informal aspects of organisations.
Reason advocates that OHSMS must be designed from the assumption that humans are fallible.
Hopkins advocates that rule compliance is superior for guiding day to day practice, if rules are generated through shared learning, in place of the risk assessment approach that is commonly part of OHSMS where all risk assessments are devolved to "inexpert and task focused" frontline workers (Hopkins 2008: 161).
ANSI's report, titled "International Standardization of OHSMS - Is There a Need?
The ANSI report notes that the possibility of ISO's developing of an OHSMS standard arose in the context of both ISO 9000 and ISO14000, the quality management and the environmental management systems standards, respectively.
At the same time, the organization says, an ISO OHSMS would focus on systems, "and some of these systems extend beyond the occupational health and safety arena.
ANSI, which defines itself as a catalyst for the development of national consensus standards and is the US member to the ISO and the International Electrotechnical Commission, lists these possible advantages of an ISO OHSMS standard:
as a systematic approach to OHSMS leading to improved performance in the health and safety area;
as an OHSMS baseline and vocabulary, which may assist companies in establishing a common platform for addressing and communicating occupational health and safety issues;
