What type of containers are recommended for storing large glass fragments during evidence collection?

When collecting and storing large glass fragments as evidence, using boxes with cotton or tissue to separate the pieces is recommended. This method provides several critical benefits. First, the cushioning material helps prevent further breakage during transport and storage, which is essential for preserving the integrity of the evidence. Glass can be fragile, and any additional stress can create more shards or alter the shape of existing fragments, potentially compromising their forensic value.

Additionally, using a rigid box minimizes the risk of the glass fragments being damaged or lost. Unlike soft containers such as plastic bags, which may allow movement and jostling, a box maintains structure and allows for better organization of the fragments. This is especially important in forensic contexts where the positioning and condition of evidence can provide vital information during investigations.

Other options, such as pill bottles or paper bags, do not offer the same level of protection and containment for larger pieces of glass. Pill bottles may be too small and may not adequately protect larger shards, while paper bags can allow the glass to move around, increasing the chance of breakage. Plastic bags are flexible and can cause shards to compress against each other, leading to additional fragmentation. Therefore, boxes with cotton or tissue are the most suitable choice for this particular type of evidence collection.
