NEBOSH IDip study plan

Map the full Domain 1 syllabus into a one-page concept map linking OHS management systems, policy, organising, planning and measuring, and review.

Define and distinguish the core management-system vocabulary (policy, objectives, hazard, risk, residual risk, hierarchy of controls, competent person, consultation) in your own written definitions.

Compare the main OHS management-system models and identify the common Plan-Do-Check-Act structure they share, noting where they differ.

Explain how national legal frameworks and international labour standards interact with an organisation's own OHS management system.

Analyse how leadership, worker consultation and safety culture interact, and identify at least five indicators of a weak versus strong culture.

Construct the business case for OHS, using cost-of-accident reasoning (direct and indirect costs, insured and uninsured) with worked figures.

Evaluate the purpose and limitations of performance monitoring, including both active and reactive indicators, and select suitable KPIs for a named scenario.

Justify the role of audit, management review and continual improvement in closing the loop of the management cycle.

Build a hazard-classification grid covering physical, chemical, biological, ergonomic and psychosocial agents, with one example control per category.

Apply the hierarchy of controls to at least six different hazards and justify why each chosen control sits where it does.

Explain the principles of risk assessment, including likelihood, severity, risk rating and the difference between qualitative and semi-quantitative approaches.

Describe the purpose and content of a safe system of work and a permit-to-work, and state when each is appropriate.

Explain the mechanisms of fire initiation, spread and detection, and select suitable fire prevention and protection measures for a named premises.

Analyse the causes and controls of work-related musculoskeletal disorders, including manual handling, repetitive work and display-screen ergonomics.

Evaluate noise and vibration hazards, including exposure limits, measurement concepts and the hierarchy of noise controls.

Distinguish the principal occupational health hazards (dusts, fumes, solvents, biological agents) and match each to appropriate exposure-control strategies.

Explain the principles of machine safety, including guarding, interlocks and the concept of a safe approach to hazardous machinery.

Analyse electrical hazards and the controls appropriate to work on or near live systems, including isolation and verification procedures.

Evaluate the management of confined spaces and work at height, identifying the specific controls and permit arrangements each demands.

Describe the causes of major accident hazards and the elements of a process-safety management approach for high-hazard installations.

Explain the structure and assessment criteria of the practical application, including what a strong inspection report and action plan look like.

Conduct a structured workplace inspection of a real or simulated site and record observations against a checklist you have designed.

Convert inspection findings into prioritised, costed and time-bound recommendations with named responsible persons.

Practise writing concise, evidence-based observations that distinguish immediate, underlying and root causes.

Draft a professional-development plan identifying your own competence gaps against the diploma's expected knowledge areas, with actions and timescales.

Explain the ethical responsibilities of an OHS practitioner, including honesty in reporting, managing conflicts of interest and confidentiality.

Prepare a written argument for influencing senior decision-makers on an OHS issue, using evidence and cost-benefit reasoning.

Complete two timed written-answer exercises under exam conditions and self-mark them against the command words used.

Synthesise all four domains into an integrated revision map showing where management-system, hazard-control and professional-practice content overlap.

Complete a full timed mock examination across all domains and mark it against model answers and command-word expectations.

Identify and close your three weakest areas with targeted re-study and a short written summary of each.

Rehearse concise verbal explanations of ten key concepts to test recall under time pressure.
