Exposure may occur by ingestion when foods or beverages are consumed in drug administration areas, or by hand-to-mouth transfer of drug residue from HD contaminated surfaces (ASHP, 2006). INHALATION Inhalation of toxic vapors, mists, gases, or dusts can produce poisoning by absorption through the mucous membrane of the mouth, throat, and lungs and can seriously damage these tissues by local action. Chemical Exposure to Skin: Immediately flush with cool water for at least 15 minutes. A biological hazard, or biohazard, is a biological substance that poses a threat to the health of living organisms, primarily humans.This could include a sample of a microorganism, virus or toxin that can adversely affect human health.A biohazard could also be a substance harmful to other animals. Studies show that absorption of chemicals through the skin can occur without being noticed by the worker, and in some cases, may represent the most significant exposure pathway. If there are no visible burns, remove all jewelry and apply soap to area. Both the characteristics and size of the potentially exposed population need to be determined. A failure to properly remove such substances can contribute to unhealthy and dangerous environments. Permissible Exposure Limit (PEL): The maximum legal time-weighted average airborne exposure permitted during an 8-hour work day, published and enforced by OSHA. Scope . • Safety Data Sheets 1. -- Wiping chemical drips or residue from the outside of containers will lessen the chance of chemical exposure-- Food and chemicals may be stored in the same refrigerator as long as both are clearly labeled.
