What are the characteristics of R22?
Direct Answer
Option A: All of the above
R22 is a colourless, odourless, and non-flammable gas under standard conditions. These physical characteristics make it effective for refrigeration but also dangerous in confined spaces, as leaks may not be immediately detectable by smell. Proper ventilation and leak detection are mandatory to ensure safety during maintenance of shipboard cooling systems.
