What is an important characteristic of a support kit used by first responders?

The characteristic of being small and portable is crucial for a support kit used by first responders. In emergency situations, responders must act quickly and efficiently, often in confined spaces or challenging environments. A support kit that is small and portable ensures that it can be easily carried or accessed without hindering the first responder's mobility. This allows them to focus on providing care and support to those in need without the added burden of transporting a cumbersome kit.

In contrast, a heavy and sturdy support kit might provide durability but can impede swift action. A kit filled with an excessive number of items might lead to clutter and confusion, making it difficult for responders to quickly find what they need. Color-coding can be beneficial for organization, but it is not an essential characteristic compared to the necessity of portability, especially when time is of the essence during emergencies.
