Which exposure route is the second most common route of exposure?

Explanation:
Exposure routing and how people encounter hazards varies by setting, but inhalation is usually the most common route because many substances become airborne. The second most likely route is tied to contexts where contact with sharps is common—needles, syringes, and other contaminated sharp instruments can introduce substances directly into the body through injection. In environments like healthcare, veterinary work, or certain labs, this injection pathway emerges as the next most frequent exposure route after inhalation. So, recognizing injection as the second most common route reflects those circumstances where sharps-related exposures are a major concern.
