What are the three ways to be exposed to a hazardous substance?
The three main ways to be exposed to a hazardous substance are inhalation (breathing it in), ingestion (swallowing it), and dermal contact (skin contact). These exposure routes can occur through accidental spills, leaks, or improper handling of hazardous materials. It is important to follow proper safety procedures to minimize the risk of exposure.
What are the four possible routes of exposure to hazardous substances?
Inhalation is the most common route for exposure to a hazardous material. Other possible routes include:skin contactskin absorptioninjectioningestion (eating or drinking)
