OSH Management and Risk Control
OSH Management and Risk Control
This domain tests OSH management systems and risk control: HIRARC, PDCA, performance monitoring, management review, contractors and emergency preparedness. The exam wants a systematic process that links hazard identification to controls and verifies residual risk.
Core rules
- HIRARC (DOSH Guidelines 2008): hazard identification, risk analysis, risk evaluation, risk control. Use likelihood × severity; record residual risk after controls.
- OSH-MS follows PDCA: policy and leadership; planning (hazards, legal requirements, objectives); implementation and operation; checking (monitoring, audit, incident investigation); management review and improvement. MS 1722 and ISO 45001 are common references.
- Risk control follows the hierarchy; controls need owners, deadlines and verification. Risk assessment is living: review after changes, incidents, new chemicals or new contractors.
- Contractor management: selection, induction, permit-to-work, supervision and shared risk assessment. Emergency preparedness: scenarios, roles, drills, rescue and first aid.
Worked example
A warehouse manual-handling task is scored likelihood 4 × severity 3 = 12 (high). Controls: eliminate by automating pallet movement; if not practicable, use mechanical aids, adjust shelf heights, train and rotate staff. Re-score after controls: 2 × 3 = 6 (medium), with residual risk monitored. Simply issuing back belts would not reduce the task risk enough and is PPE-level.
Traps
- Scoring risk without a defined matrix or consistent likelihood.
- Writing controls with no owner or completion date.
- Not re-assessing after change or incident.
- Treating contractor safety as the contractor's problem alone.
