F-Gas Category I study plan

Map each legal duty in the F-Gas and ODS framework to the role that carries it (operator, certified technician, wholesaler)

List the threshold refrigerant charge quantities that trigger leak-check frequency, record-keeping and inspection obligations

Define global warming potential and ozone depletion potential and rank the common refrigerant families by both metrics

Explain the environmental mechanism behind each metric in your own words without notes

Distinguish the record types an operator must keep (equipment records, service records, recovery and disposal records) and state the retention period for each

Identify which activities legally require a certified person and which do not

Calculate the CO2-equivalent of a given charge from its GWP and mass, working five practice problems

Describe the phase-down schedule for hydrofluorocarbons and what it means for placing new equipment on the market

Sequence the commissioning steps for a new system from pre-installation checks through tightness testing and handover

Perform a strength and tightness test calculation using the correct test pressures and hold times

Draft a complete commissioning record including charge, component identification and test results

Select the appropriate leak detection method for a given access situation and justify the choice

Build a leak-check schedule for three systems of differing charge sizes and locations

Diagnose five written fault scenarios and identify whether the cause is a leak, a restriction, or a charge issue

Explain how indirect leak-detection methods (pressure, temperature, sight glass, electronic detection) complement each other

State the actions required once a leak is confirmed, including repair timelines and re-testing

Compare recovery, recycling, reclaim and disposal and state where each is legally and technically appropriate

Describe the recovery procedure for a system from the service valve through cylinder filling, including vapor versus liquid recovery

Identify the purity and handling requirements that determine whether recovered refrigerant can be reused

Explain the decommissioning and disposal path for refrigerant and for the equipment itself

Identify cylinder markings, color codes and valve types and match each to its refrigerant and safe use

State the maximum fill ratio and the safety reason behind it, then calculate the fill limit for two cylinder sizes

List the hazards of common refrigerants (toxicity, flammability, asphyxiation, frostbite) and the control for each

Describe safe handling, storage and transport requirements for full and empty cylinders

Reconcile a set of service records against the legal record-keeping requirements and flag every gap

Trace a refrigerant charge from delivery through recovery and disposal across a full equipment lifecycle

Answer twenty mixed-domain practice questions under timed conditions

Write a short corrective action plan for the three weakest areas the practice test exposes

Complete two full-length timed mock exams and score each

Review every missed question and write the underlying rule or fact it tested

Re-test the weakest two domains until scores are stable across two attempts

Confirm the practical tasks (recovery, tightness testing, cylinder handling) can be described end to end without notes
