Which term refers to the process of releasing pressure by burning a flammable vapor or liquid?

• A. Flushing
• B. Vapor suppression
• C. Flaring
• D. Absorption

Answer: (C)

Flaring is the controlled burning of flammable vapors or liquids to relieve pressure safely. By burning off excess gas, you prevent overpressure and reduce the risk of an uncontrolled release or explosion. The flame converts the material into combustion products like carbon dioxide and water, making the release less hazardous than venting raw vapors. Flushing, by contrast, uses a fluid to push contents out and doesn’t involve burning. Vapor suppression aims to keep vapors from escaping, not to release them by combustion. Absorption involves dissolving the gas into a liquid, not burning it.
