Why are victims who smell a chemical considered exposed?

• A. They have ingested the chemical
• B. It indicates the chemical has entered the working zone
• C. They are in a safe distance and are not at risk
• D. They will likely show no symptoms at this stage

Answer: (B)

Victims who smell a chemical are considered exposed because the detection of an odor often indicates that the chemical has entered the working zone. When a chemical is present in the environment to the point that it can be smelled, it suggests that the substance is dispersing in the air, which could pose a risk of inhalation or contact. This can lead to potential exposure to harmful effects, even if the victims do not show immediate symptoms. Recognizing the smell of a chemical is a key sign that individuals are in proximity to it and may be at risk, and it necessitates appropriate safety measures to be implemented to protect their health.
