Final answer:
Cleaning solutions must indeed be stored in their original containers to ensure safety and proper handling. This is a crucial safety practice in laboratories and workplaces where chemicals are used, as it helps prevent accidents and provides important information on the substances being handled.
Step-by-step explanation:
It is true that cleaning solutions must be stored in their original containers. This practice is essential for maintaining safety in any environment where chemicals are used, such as a laboratory. Storing chemicals in their original containers prevents the accidental use or mixing of substances that could cause dangerous reactions. It also ensures that all handling and hazard information provided by the manufacturer is readily available to the user.
Applying cosmetics in a lab is not allowed as it could contaminate the products and may lead to safety hazards. In case of an accident, it is critical to call your teacher immediately and know the location of safety equipment like fire extinguishers and eyewash stations. Proper disposal of waste is equally important, and chemicals should never be disposed of down the sink; instead, follow the guidelines provided by your teacher or institutional protocol.
Materials such as sodium, which is highly reactive, or chlorine, a poisonous gas, require specific storage conditions to guarantee safety, as illustrated in Figure 5.2.1.
