Sharps waste
Summary
Sharps waste is a form of biomedical waste composed of used "sharps", which includes any device or object used to puncture or lacerate the skin. Sharps waste is classified as biohazardous waste and must be carefully handled. Common medical materials treated as sharps waste are
hypodermic needles,
disposable scalpels and blades,
contaminated glass and certain plastics, and
guidewires used in surgery.
In addition to needles and blades, anything attached to them, such as syringes and injection devices, is also considered sharps waste.
Blades can include razors, scalpels, X-Acto knives, scissors, or any other items used for cutting in a medical or biological research setting, regardless of whether they have been contaminated with biohazardous material. While glass and sharp plastic are considered sharps waste, their handling methods can vary.
Glass items which have been contaminated with a biohazardous material are treated with the same concern as needles and blades, even if unbroken. If glass is contaminated, it is still often treated as a sharp, because it can break during the disposal process. Contaminated plastic items which are not sharp can be disposed of in a biohazardous waste receptacle instead of a sharps container.
Injuries from sharps waste can pose a large public health concern, as used sharps may contain biohazardous material. It is possible for this waste to spread blood-borne pathogens if contaminated sharps penetrate the skin. The spread of these pathogens is directly responsible for the transmission of blood-borne diseases, such as hepatitis B (HBV), hepatitis C (HCV), and HIV. Health care professionals expose themselves to the risk of transmission of these diseases when handling sharps waste. The large volume handled by health care professionals on a daily basis increases the chance that an injury may occur.
The general public can occasionally be at risk of sustaining injuries from sharps waste as well when hypodermic needles are improperly disposed of by injection drug users.
