BOSH SO2 study plan

BOSH SO2 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Risk assessment and control & Workplace hazards and controls (physical, chemical, biological, ergonomic, psychosocial)

  • Distinguish hazard from risk and apply a five-step risk assessment process to three worked scenarios covering physical, chemical and ergonomic hazards

  • Build a hierarchy-of-controls decision table that maps at least eight control options to the hazards they best address

  • Explain the difference between likelihood, severity and residual risk, and calculate a simple risk score for each scenario

  • Identify the exposure routes (inhalation, ingestion, dermal, injection) for five common workplace substances and state the control that interrupts each route

Your checkpoint

A one-page risk assessment template plus three completed assessments with scored residual risk and named controls

Week 2

Workplace hazards and controls (physical, chemical, biological, ergonomic, psychosocial)

  • Classify at least twelve workplace hazards into physical, chemical, biological, ergonomic and psychosocial categories with a control for each

  • Describe the health effects and exposure limits concept for noise, vibration, heat and dust

  • Explain how ergonomic risk factors such as repetition, force, posture and duration combine to cause musculoskeletal injury

  • Outline the main psychosocial hazard categories and one organisational control for each

Your checkpoint

A hazard register of twelve hazards with category, health effect, exposure route, control and monitoring method

Week 3

Workplace hazards and controls (physical, chemical, biological, ergonomic, psychosocial) & Risk assessment and control

  • Select and justify monitoring methods (air sampling, noise dosimetry, thermal assessment, ergonomic screening) for six hazards

  • Evaluate the effectiveness of controls using the hierarchy and identify at least three common control failures

  • Apply the principles of prevention to a task involving hazardous chemicals and propose substitution or engineering options

  • Explain how to communicate residual risk and required precautions to a work team in plain language

Your checkpoint

A control effectiveness review of one realistic work task, including monitoring plan and worker briefing notes

Week 4

Health and safety management systems & Health and safety foundations and legal framework

  • Compare the plan-do-check-act cycle with the core elements of a recognised occupational health and safety management system

  • Map the legal duties of employer, employee and self-employed person onto a sample organisation chart

  • Explain the role of policy, leadership commitment, worker consultation and competence in a management system

  • Identify the documentation a management system needs (policy, risk assessments, records, procedures) and the retention logic for each

Your checkpoint

A management system gap analysis against ten system elements, with a prioritised action list

Week 5

Incident investigation, recording and reporting & Emergency preparedness and response

  • Apply an incident investigation method to a described event, separating immediate causes from root causes

  • Distinguish incident, accident, near miss and dangerous occurrence, and state which require recording or reporting

  • Draft an emergency response plan covering fire, chemical release and medical emergency, including roles and evacuation routes

  • Design a post-emergency review that feeds lessons back into risk assessment and training

Your checkpoint

A completed incident investigation report with root-cause analysis and five corrective actions, plus a one-page emergency plan

Week 6

Monitoring, auditing and performance measurement & Workforce health and wellbeing

  • Define leading and lagging performance indicators and select four of each for a sample workplace

  • Design an audit or inspection checklist that tests implementation, not just documentation

  • Explain how health surveillance, exposure monitoring and wellbeing programmes differ in purpose and legal basis

  • Identify the main causes of work-related stress, fatigue and mental ill health, and one intervention at each level of prevention

Your checkpoint

A monitoring and audit pack containing an indicator dashboard, an inspection checklist and a wellbeing action plan

Week 7

Contractor and supply chain management & Environmental and sustainability considerations

  • Explain how to pre-qualify a contractor on competence, insurance, method statements and past performance

  • Describe how to control contractor risk through induction, permits, supervision and handover

  • Identify the environmental impacts of a chosen work activity and apply the waste hierarchy to reduce them

  • Explain how sustainability measures such as energy, water and material efficiency also reduce health and safety risk

Your checkpoint

A contractor management procedure and an environmental aspect-and-impact register for one work activity

Week 8

Health and safety foundations and legal framework & Health and safety management systems & Risk assessment and control & Workplace hazards and controls (physical, chemical, biological, ergonomic, psychosocial) & Incident investigation, recording and reporting & Emergency preparedness and response & Monitoring, auditing and performance measurement & Workforce health and wellbeing & Contractor and supply chain management & Environmental and sustainability considerations

  • Consolidate all domains by working through a full-length practice paper under timed conditions

  • Review every incorrect answer and trace it back to the relevant domain and source concept

  • Revisit the three weakest domains and produce a one-page summary of the key facts and decision rules for each

  • Rehearse explaining the hierarchy of controls and the risk assessment process aloud in under five minutes each

Your checkpoint

A timed practice score log with error analysis and three one-page revision summaries

Milestones

Week 2: Can classify twelve hazards by type and name a suitable control for each without referring to notes

Week 4: Can explain the plan-do-check-act cycle and map employer and worker legal duties to a sample organisation

Week 6: Can run a short incident investigation, produce root causes and list five corrective actions in 45 minutes

Week 8: Achieve a consistent pass-level score on a timed practice paper and explain every missed question's underlying concept
