Transportation/Storage

Extended exposure to heat or humidity causes degradation of biological evidence. To reduce this threat, the packaged items from the crime scene should be moved to a suitable storage facility as soon as possible.

Liquid samples should be transported in refrigerated or insulated containers.

Evidence should be stored in a temperature-controlled environment. Cool environments are preferred, although research has shown room temperature is suitable for storing dried stains, as long as the humidity is controlled.
