What must be done to containers to avoid chemical spills?

1. They must be closed properly

2. They must be stored in sunlight

3. They must be kept half open

4. They must be placed in a freezer

The correct answer is: They must be closed properly

Containers must be closed properly to prevent chemical spills. When containers are sealed securely, they minimize the risk of substances leaking or spilling due to accidental knocks, temperature changes, or pressure fluctuations. Proper sealing also protects the contents from contamination by external elements, such as moisture or dust, which can compromise the integrity of the chemical. Inappropriate practices, such as storing them in sunlight or keeping them half open, can lead to chemical breakdown due to heat or evaporation. Additionally, placing them in a freezer could alter the properties of certain chemicals, potentially making them dangerous or ineffective. Keeping containers properly closed is essential for maintaining safety and preserving the quality of the substances stored inside.
