General Packaging Requirements and Tips
- ALL Evidence packaging must be at least 6" long on one side.
- Manila window envelopes are ideal packaging as they are both breathable and allow for viewing the contents. Paper bags, plastic zip-type bags and manila envelopes of an appropriate size are also good choices.
- Swab boxes must be packaged inside another paper bag/envelope.
- Glass containers should be avoided. If necessary, they must be packaged inside another non-breakable container (paint can, plastic container) to prevent breakage.
- Evidence that has any suspected biohazardous material on it must be clearly marked on the outer packaging with a BIOHAZARD sticker.
- Syringes must be packaged in clear, puncture-resistant packaging (i.e. syringe tube), and the tube should further be packaged inside a window envelope or clear plastic bag (if no BIO exams are requested).
- All suspected PCP or butane honey oil must be packaged in arson packaging (paint can or arson bag).
- All evidence for BIO exams must be packaged in breathable packaging (e.g paper bag, window envelope)
Sealing the Evidence
A package is properly sealed if:
- It prevents loss, cross-transfer or contamination of the evidence.
- Entering the container results in obvious damage/alteration to the container or seal.
The seal must consist of evidence tape, self-sealing evidence bags or heat seals. Please ensure when using evidence tape that the tape completely covers open seams/edges of the container.
Initials or other identification of the sealer (badge number, etc) must be ON or ACROSS the seal.
