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.

chemicals. The treatment of produced water is very critical since it contains "hazardous organic and inorganic constituents". Some organic detected compounds are polyaromatic hydrocarbons (PAHs), aliphatic hydrocarbons and long chain fatty acids. The chemical compounds related to HF are ethoxylated surfactants and the biocide 1,2,5trimethylhexahydro-1,3,5-triazine-2-thione (a dazomet derivative).
