1 A Persistent Disconnect between Organizational Aspects and Engineering
If you open the plates of a circuit breaker, you will eventually have an arc. You don’t want the electrons to arc, but no engineer would say that the electrons that formed the arc were lazy or complacent: if you don’t want the arc, you engineer the system around the constraint. Human factors engineering operates according to the same principle; identify the constraints in the interactions between the employees and the workspaces, tools, and technology, and engineer around it.1

3 The Need for Clarifying Key Concepts
Safety is more than the absence of risk; it requires specific systemic enablers of safety to be maintained at all times to cope with the known risks, [and] to be well prepared to cope with those risks that are not yet known [21].
4 Some Propositions about the Implementation of Safety Management Systems
-
achieving a widely distributed acceptance of safety management as an integral part of actual jobs in the organization,
-
a collectively shared set of assumptions and values concerning safety (a “safety culture”) and
-
commitment to safety as part of the individual identity of personnel in an organization.
-
metrics identifying and addressing precursor management to add granularity to safety performance assessments apart from accidents.
