What are the common routes of exposure to chemical agents?

• A. Inhalation and ocular contact
• B. Ingestion and dermal contact
• C. Inhalation, dermal contact, and ingestion
• D. Inhalation, ingestion, and visual contact

Answer: (C)

The common routes of exposure to chemical agents include inhalation, dermal contact, and ingestion, making the selected answer accurate. Inhalation is one of the primary routes through which individuals can be exposed to chemical agents, especially in scenarios involving toxic gases, vapors, or aerosols. When these agents are airborne, they can be rapidly absorbed through the respiratory system, leading to immediate health effects. Dermal contact also plays a significant role in exposure, as many chemical agents can penetrate the skin, particularly if the skin is compromised or if the chemical is in a form that facilitates absorption. This route is especially relevant when dealing with liquid substances or contaminated surfaces. Ingestion is another route of exposure, albeit less common in emergency settings, where individuals might inadvertently consume chemicals through contaminated food, water, or by hand-to-mouth transfer after handling chemical substances. By encompassing all three routes— inhalation, dermal contact, and ingestion— this answer accurately reflects the various means by which chemical agents can enter the body, thereby providing critical information for medical personnel and first responders in their assessment and response strategies.
