Biohazard Kit
This is a simple kit meant to protect the collectors AND the lab technicians who recieve the evidence.  It may contain...

Metal cans to hold needles and sharp evidence

Biohazard warning seals and tape

The only plastic bags truly allowed to hold evidence (and it is to place properly collected evidence like blood in glass vials as added protection against breakage or leaking!)

Hard container to place evidence in for transport
