COSH SO2 study guide

COSH SO2 · Work through your exam, one topic at a time.

The COSH SO2 credential sits at the supervisory level of construction occupational safety and health practice. It is aimed at site supervisors, foremen, safety officers and engineers who already know the basics and now need to plan, inspect and enforce safe work on a live site rather than simply follow instructions. The COSH SO2 study guide has 9 sections and about 2,744 words.

01

Occupational Safety and Health Legislation and Regulations

Domain 1 tests whether you can identify duty holders, apply the test of reasonable practicability, and choose the correct enforcement outcome for a given site failure. Employer / principal contractor: safe plant and substances, safe systems of work, competent supervision, information, instruction and training, safe access and egress, and welfare facilities.

02

Hazard Identification

Domain 2 tests whether you can find hazards before they cause harm, separate hazard from risk, and pick an identification technique that fits the task. A hazard is the potential to cause harm (a tower crane, respirable crystalline silica).

03

Risk Assessment and Control

Domain 3 tests the five-step assessment cycle, the scoring matrix, and whether your chosen controls genuinely follow the hierarchy. Identify hazards; decide who may be harmed and how; evaluate risk and set controls; record significant findings; review at defined triggers (change, incident, new information, periodic date).

04

Construction Site Safety Management and Supervision

Domain 4 tests how safety is actually run on a live site: coordination, supervision presence, permits, statutory inspections and control of subcontractors. Construction phase plan and site-specific arrangements, updated as the site changes.

05

Workplace Inspection and Accident Investigation

Domain 5 tests planned inspection technique and the discipline of moving from immediate cause to root cause without blaming individuals. Plan inspections by area, activity and previous findings; use a checklist that matches the site, not a generic form.

296 words, about 1 min
06

Safety Training and Communication

Domain 6 tests whether training is targeted, understood and verified, and whether site communication reaches the people who actually do the work. Base the training plan on the risk assessment, roles and tasks, and statutory requirements for particular activities (plant operation, scaffolding, first aid, supervisory roles).

07

Occupational Health and Hygiene

Domain 7 tests the classic hygiene sequence and whether you can apply exposure limits and surveillance to construction health risks. Anticipate the hazard before work starts, recognise it on site, evaluate exposure by measurement, then control and verify.

08

Emergency Preparedness and Fire Safety

Domain 8 tests whether your emergency arrangements still work on a site whose layout and population change weekly, and whether you can match fire control to the fuel and the fire class. Foreseeable emergencies; alarm and detection; escape routes kept clear and signed; assembly point located outside the danger zone; roll call using a visitor and contractor log; nominated marshals, first aiders and rescue teams; communication and emergency service liaison; drills with debrief and actions; review after any change or near miss.

09

Safety and Health Records, Reporting and Documentation

Domain 9 tests record discipline: what must be kept, for how long, who may see it, and how data become a reported indicator rather than a filing cabinet. Statutory inspection reports: scaffolds, excavations, lifting equipment, LEV and pressure systems.
