Regarding the safe packaging of laboratory chemicals for transport or shipment, you must always do which of the following?

When transporting or shipping laboratory chemicals, ensuring that the packaging can withstand rough handling is essential for maintaining safety and preventing accidents. Laboratory chemicals can be sensitive and hazardous, so robust packaging protects both the contents and anyone who may handle the package. This includes considerations such as resistance to impacts, punctures, and environmental conditions during transit. Using appropriate materials and designs suitable for the specific type of chemical being transported is crucial to avoid leaks, spills, or breakage, which could lead to serious safety risks.

The other options may seem relevant in specific contexts, but they do not encompass the primary requirement for safe transport. Glass containers, for instance, can be fragile and may not always provide the durability needed for transport, especially in scenarios where rough handling is a possibility. Sealing containers with tape can be a helpful measure, but it does not address the inherent strength and safety of the packaging itself. Similarly, labeling with bright colors can enhance visibility but is not a substitute for securely packaged and protected contents. Thus, the priority always lies in the integrity and resilience of the packaging to ensure maximum safety during transportation.
