Consider the following:1. Aerosols2. Foam agents3. Fire retardants4. Lubricants In the making of how many of the above are hydrofluorocarbons used?
✓ Correct answer: c) Only three
ExplanationHydrofluorocarbons (HFCs) are a climate “Super- Pol- lutant” - Greenhouse gases with hundreds to thousands of times the heat-trapping power of carbon dioxide (CO2).HFCs are syn- thetic gases used in air conditioning systems, aerosol propel- lants, foam- blowing agents, solvents, and flame retardants.These gases were first developed as alternatives to ozone- de- pleting chemicals, but after their rollout, it was learned that their release to the atmosphere during manufacturing processes and leakage during use, servicing, and retirement/replacement of equipment poses a grave threat to our climate.Lubricants are typically based on oils and synthetic esters, not HFCs.64
