Prosector
Generally, the risks to prosectors are low. Cadavers used for teaching purposes are embalmed before they are encountered by a prosector and students. Embalming fluid usually contains formaldehyde, phenol, Dettol, and glycerine which disinfect and kill pathogens within the cadaver. With exposure to embalming fluid, tissues and bodily fluids, such as blood, become fixed. Prosectors and students working with embalmed cadavers must always wear protective gloves, however this is more for protection against the harsh chemicals used in embalming such as formaldehyde and dettol which can cause moderate to severe skin irritation.
Embalming
Anatomical embalming is performed into a closed circulatory system. The fluid is usually injected with an embalming machine into an artery under high pressure and flow, and allowed to swell and saturate the tissues. After the deceased is left to sit for a number of hours, the venous system is generally opened and the fluid allowed to drain out, although many anatomical embalmers do not use any drainage technique.
