Safety Management Systems
Overview
A safety management system is the organized, documented set of policies, processes, and reviews that turns good intentions into repeatable performance. The exam expects you to recognize the elements of ANSI/ASSP Z10.0 and ISO 45001:2018 and to know how they cycle.
Common architecture. Both standards follow Plan-Do-Check-Act: management leadership and worker participation; planning (context, hazard identification, risk assessment, legal and other requirements, objectives); implementation (resources, competence, communication, operational control, contractor control); evaluation (monitoring, measurement, internal audit, incident investigation); and management review with corrective action.
Key distinctions.
- ISO 45001 requires documented information where needed, not a prescribed manual full of documented procedures.
- Consultation and participation of workers is a mandatory element, not an optional nicety.
- Auditing tests conformity of the system; inspection looks at physical conditions. Do not swap them.
- Leading indicators (near-miss reporting, training completion, audit closure) predict; lagging indicators (TRIR, DART) describe what already happened.
Traps. Candidates confuse conformance (met the requirement) with performance (achieved the outcome). They also forget that top management must be accountable, not merely supportive, and that objectives must be measurable and monitored.
Worked example
An organization has a low TRIR but no hazard identification process and no internal audit. Under Z10 or ISO 45001 it does not conform: absence of injuries is not evidence of a functioning system. The correct answer is to treat the missing processes as the finding.
