4. Identification, transport, storage and safe handling of refrigerants
5. Servicing tools and equipment for traditional and natural fluids hydrocarbons
6. Best practices in servicing systems
a. Leak detection, b. Recovery
c. Vacuum, d. Charge
e. System operation and parameters reading
7. Safety, logging (record keeping) and labelling considerations.
