Types of Underwater Hazards
Objective: Develop the knowledge and practical skills required to identify, evaluate, and manage underwater hazards that may occur during commercial diving operations to prevent injury, entrapment, exposure, and fatality.
Knowledge: Explain environmental, operational, and structure-related underwater hazards including currents, weather, sea state, shipping lanes, confined spaces, differential pressure (Delta P), night diving risks, cold water exposure, zero visibility, drill mud hazards, contaminated environments, offshore structures, scaffolding, entrapment dangers, and surface visibility requirements, as well as the controls used to reduce risk.
Skills: Demonstrate hazard management competence by recognising hazards in scenario-based situations, selecting appropriate controls, applying safe dive planning and operational decisions, and implementing correct emergency response actions when hazard exposure occurs.

Safety Information
Objective: Develop the knowledge and practical skills required to recognise, avoid, and respond correctly to differential pressure (Delta P) hazards in commercial diving environments.
Knowledge: Explain how Delta P occurs, why it is highly dangerous and often fatal, where high-risk suction/pressure-differential zones are commonly found, and the key safety principles for exclusion, prevention, and emergency response.
Skills: Demonstrate Delta P hazard competence by identifying risk zones in scenario-based situations, applying exclusion and avoidance controls, and selecting correct safety actions and reporting procedures when Delta P risk is present.

Safety Flashes
Objective: Develop the knowledge and practical skills required to learn from real-world diving incidents and apply preventative safety behaviours to avoid injury or fatality during commercial diving operations.
Knowledge: Explain the hazards highlighted in safety flash incidents, including entrapment, differential pressure (Delta P), high-pressure leaks, diver injury, and being trapped underwater, as well as the unsafe actions and conditions that led to these incidents.
Skills: Demonstrate safety awareness by analysing safety flash scenarios, identifying what went wrong, and applying correct prevention, avoidance, and emergency response actions in similar operational situations.
5
Practice Test
Objective: Develop and test hazard competence through a structured assessment covering underwater hazard recognition and safe operational responses.
Knowledge: Explain key hazard types, risks, and control measures through formal written practice assessment questions.
Skills: Demonstrate hazard decision-making competence by applying correct safety actions and controls across scenario-based practice test questions.

Final Assessment
Objective: Demonstrate competence by completing the final underwater hazards assessment and confirming readiness for safe commercial diving operations.
Knowledge: Explain underwater hazard management principles, high-risk hazard controls, and emergency response priorities through final assessment questions.
Skills: Demonstrate applied hazard competence by selecting correct responses to complex underwater hazard scenarios in the final exam.
