What is the importance of not using gravity for dispensing certain liquids above a specific temperature?

• A. It can lead to leaks
• B. It increases flammability risks
• C. It may cause pressure build-up
• D. It is not efficient

Answer: (B)

The importance of avoiding gravity for dispensing certain liquids above a specific temperature primarily revolves around the increased flammability risks. When certain liquids are heated beyond their flash point, they can become much more volatile and easily ignitable. Using gravity to dispense these liquids could result in unintentional spills, thus exposing them to ignition sources and creating a significant fire hazard. Additionally, as the temperature rises, the vapor pressure of these liquids can increase, which can further contribute to the risk of fire if the vapors come into contact with any ignition source. Therefore, dispensing methods that do not rely on gravity can help minimize the risk of flammable vapors escaping into the environment and reduce the potential for ignition. The other options highlight various concerns with liquid dispensing, but they do not encompass the heightened flammability and safety risks posed by handling certain heated liquids without appropriate precautions.
