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.
Stink Blasters
MEG has never explicitly described what goes into making the scents, because they are afraid of knock off brands. They have said that to make the scent formulas, they use about 95 percent polypropylene glycol (used most commonly as a moisture-carrying agent in cosmetics), and the last 5 percent are oils, food flavorings and extracts. Scientists carefully analyze the scents to match what they are supposed to smell like. Another important factor in the scents is the emission of cyclohexanone and toluene. Though the chemicals are naturally toxic, MEG is careful to use them at levels much lower than established permissible exposure limits, so they are safe. They make the formulas in laboratories in the United States, although the toys are produced in China. This is so because they want to control the quality of the toys. MEG is also careful not to include materials that one could be allergic to in the toys.
