cross-sector

Refrigerants is an essential knowledge of the following occupations:

Steam engineer: Steam engineers provide energy and utilities to facilities, such as steam, heat and refrigeration. They operate and maintain equipment such as boilers and air compressors, and research and develop new methods and improvements for the provision of utilities.
Heating, ventilation, air conditioning and refrigeration engineering technician: Heating, ventilation, air conditioning and refrigeration engineering technicians aid in the design of devices which provide heating, ventilation, air conditioning and possibly refrigeration in buildings. They ensure the equipment complies with environmental standards. They handle hazardous materials used in the systems, and ensure safety precautions are in place.
Heating, ventilation, air conditioning (and refrigeration) service engineer: Heating, ventilation, air conditioning (and refrigeration) service engineers install and maintain industrial heating, air conditioning and possibly refrigeration systems. They set up furnaces, thermostats, ducts, vents, and other equipment needed to ensure the controlled passage and treatment of air. They also carry out repairs.

Refrigerants is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Heating, ventilation, air conditioning engineer: Heating, ventilation, air conditioning engineers design and develop heating, ventilation, air conditioning and possibly refrigeration systems for usage in residences, manufacturing sites, offices, commercial buildings, etc. They strive for solutions that serve the needs of clients and respond to architectural restrictions of sites.
Mechanical engineer: Mechanical engineers research, plan and design mechanical products and systems and supervise the fabrication, operation, application, installation and repair of systems and products. They research and analyse data.
Drafter: Drafters prepare and create technical drawings using a special software or manual techniques, to show how something is built or works.
Energy engineer: Energy engineers design new, efficient and clean ways to produce, transform, and distribute energy to improve environmental sustainability and energy efficiency. They extract energy through natural resources, such as oil or gas, or renewable and sustainable sources, such as wind or solar power. 
Heating, ventilation, air conditioning (and refrigeration) drafter: Heating, ventilation, air conditioning (and refrigeration) drafters create prototypes and sketches, technical details, and aesthetic briefings provided by engineers for the creation of drawings, usually computer aided, of heating, ventilation, air conditioning and possibly refrigeration systems. They can draft for all kinds of projects where these systems can be used.
