The "safety management system" I remember from my Exxon/esso days was designed to:
(a) ensure any troublemakers with a genuin concern for safety were identified and removed.
(b) ensure any accident or incident could be successfully blamed on a low level employee/victim.
(c) ensure that the company and senior management escaped any responsibility via plausible deniability, usually proven by the existence of lovely manuals and an internal reporting scheme.
The actual intent of the scheme was the exact reverse of the published purpose to whit forcing employees to cut corners to save money and ensuring they wore the blame for the resulting incidents and accidents.
