Exposure to toxic chemicals by injection does not occur frequently in the chemical laboratory. However, it can occur inadvertently through mechanical injury from "sharps" such as glass or metal contaminated with chemicals or when chemicals are handled with syringes. The intravenous route of administration is especially dangwous because it introduces the toxicant directly into the bloodstream, eliminating the process of absorption. Nonlaboratory personnel, such as custodial workers or waste handla-s, must be protected from this form of exposure by putting aU "sharps" in special trash containers and never in the ordinary scrap baskets. Hypodermic needles with blunt ends are available for laboratory use.
