Situational Judgement and Operational Decision-Making
What the domain tests
This domain presents realistic station and incident scenarios and asks you to choose the most appropriate action. It tests prioritisation, incident command, safety management, communication, resource allocation, escalation and awareness of procedure. The best answer is usually the one that protects life, establishes control, gathers reliable information and keeps the chain of command intact.
Core rules to apply
- Priority order: life safety, incident stabilisation, property and environmental protection. Rescue actions still require a safe system of work.
- Information before commitment: confirm location, number of casualties, access, hazards and available water. Do not commit crews on a single unverified report.
- Command and control: establish command early, designate sectors, maintain a reserve and keep a clear entry-control point.
- Communication: pass concise, factual updates to the incident commander. Do not broadcast unsupported assumptions.
- Escalation: request additional resources early when the incident exceeds the initial plan; do not wait for failure.
- Documentation and welfare: record decisions, times and actions, and rotate crews before fatigue undermines safety.
Worked example
You are the first-arriving station officer at a four-storey composite building. Smoke is issuing from the second floor. A shop worker says an elderly person is trapped on the third floor. The rear staircase is clear; the front staircase is smoke-logged. One appliance and one ambulance are on scene. Reasoning: establish command and confirm the report while crews set a water supply. Use the clear rear staircase for a BA search and rescue team with a covering jet, and keep a second team as backup and egress control. Do not send all crews into the front staircase. Request additional appliances and an ambulance officer if the casualty report is credible and the building is not yet controlled. The strongest answer combines rescue urgency with a safe access route, a reserve and explicit command.
Traps that cost marks
Acting on the loudest report without verification, committing every crew immediately, ignoring the need for a reserve, and failing to establish a clear entry-control point are common errors. So is choosing an answer that is brave but violates safety procedure. Avoid actions outside your authority, such as dismissing a credible casualty report without checking.
Exam technique
Identify the immediate life risk, then the safety constraint, then the resource implication. Reject answers that are passive when action is required and answers that are reckless when control is required.
