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.
Die casting
Water-based lubricants, called "emulsions", are the most used type of lubricant, because of health, environmental, and safety reasons. Unlike solvent-based lubricants, if water is properly treated to remove all minerals from it, it will not leave any by-product in the dies. If the water is not properly treated, then the minerals can cause surface defects and discontinuities. There are four types of water-based lubricants: oil in water, water in oil, semi-synthetic, and synthetic. Oil in water is the best, because when the lubricant is applied, the water cools the die surface by evaporating while depositing the oil, which helps release the shot. A common mixture for this type of lubricants is thirty parts water to one part oil, however in extreme cases a ratio of 100:1 is used.
