A sharps container should typically be replaced when it is three-quarters full. This guideline is in place to ensure the safe handling and disposal of sharp instruments, such as needles and blades, which pose a risk for injury and infection. By replacing the container at this level, it allows for additional room for more sharps without the risk of overflowing, which can lead to accidents.

Waiting until the container is overflowing is unsafe, as it may lead to improper disposal practices or cause the lid to be unsealable, thereby increasing the chances of a needle-stick injury. Additionally, replacing the container when it is still empty does not align with best practices, as that would not be using the container effectively and could lead to unnecessary waste of resources.

Replacing the container halfway full could also increase risks; it does not provide enough space to accommodate the volume of sharp objects that may accumulate, leading back to unsafe practices. Thus, opting for replacement when the container is three-quarters full strikes a balance between ensuring safety and maximizing use.
