Which is the least common route of chemical exposure in the workplace?

• A. Eye contact
• B. Dermal contact
• C. Ingestion
• D. Inhalation

Answer: (C)

Understanding how chemicals can enter the body in the workplace involves looking at the common routes: inhalation, dermal contact, eye exposure, and ingestion. In many settings, inhalation is frequent because chemicals can become vapors, gases, or dust that workers breathe in, and skin contact happens during handling, pouring, or splashing, making dermal exposure also quite common. Eye exposure can occur from splashes or aerosols, and is often mitigated by protective eyewear. Ingestion tends to be the least likely route because workplaces emphasize hygiene and safe practices that prevent putting contaminated hands, tools, or materials into the mouth. Rules against eating or drinking in work areas, thorough handwashing, and prompt cleaning of spills all reduce the chance of swallowing contaminants. While ingestion can occur, it relies on lapses in hygiene or eating/drinking where chemicals are present, which is much less frequent than the everyday risks of inhalation or dermal exposure.
