SSSTS Study Guide 2026

Multiplying likelihood (probability score) by severity (consequence score) in a risk matrix produces a risk rating or risk score. Higher scores indicate greater risk and priority for control action. This helps focus resources on the most significant risks.

CDM 2015 requires changing facilities where workers must change into work clothing, storage for personal clothing during the working day (separate from work clothing where necessary due to contamination risk), and facilities for drying wet work clothing.

Supervisors must have the competence — appropriate training, knowledge and experience — to manage the health and safety risks of the specific activities they supervise. A supervisor of scaffolding, for example, needs to understand scaffolding hazards and controls.

During induction, workers should be told where all welfare facilities are, how to report deficiencies, what the expectations are for maintaining cleanliness, and any specific rules (e.g., no food consumption in work areas, PPE removal before entering welfare facilities).

Induction to large groups is less effective as interaction is reduced and individual questions cannot be addressed. Smaller groups (typically 10-15 maximum) allow the inductee to ask questions, confirm understanding and engage with the content more effectively.

Workers who missed a critical toolbox talk must be individually briefed on the content before they start work involving the relevant hazards. Allowing a worker to proceed without the safety information puts them and others at risk.
