Task 1 Unit 2 Assignment 2

 Forensic Science ballistics lab procedures

There is a lot of important equipment in a ballistics lab and therefore important to keep the equipment in the best condition possible  this includes maintenance and cleaning of said equipment. The staff test guns regularly either to test their safety or to identify how someone was killed and what gun was used. Due to guns bring available in the lab they need to be returned to evidence promptly after use or returned from wherever they came from as it is dangerous to leave guns around in a lab. They also use Stereo microscopes to determine basic characteristics of bullet fragments and casing’s then they compare this to similar guns by discharging an gun into a bath of water this is so they can preserve the shell making it easier to examine for comparison when using an comparison microscope they also do this with other guns to make sure it was a gun used at the crime as well this is called the water recovery method as it is a recovery method based on using water to preserve the bullet casing without it being damaged due to impact. They also have to follow regular lab procedure as in the fact they need to wear eye protection when firing weapons and sound cancelling headphones to prevent damage to ears. However this all can only be done after proper documentation  of guns and casings examined due to them being evidence in most cases
