In storing liquid wastes, leave enough amount of head space in the container to allow for expansion and safe transportation.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

Head space is the space above the liquid inside a container. Leaving enough head space for liquid waste is essential because liquids can expand with temperature changes or gas can form during storage or transport. If the container is filled to the brim, any expansion can create pressure, leading to leaks, venting, or even container failure. Providing a safe head space prevents over-pressurization and helps ensure spills and exposure hazards are avoided during handling and shipment. So, this practice is correct.
