The second concern is the physical fragility of the evidence. Care must be taken to keep items from getting wet, stepped on etc, this can also be applied to digital evidence. Investigators have been able to examine hard disk drives that have been through fires because the drives are usually air and water tight and impervious to temperatures into the thousands of degrees.
