What is one of the primary signs of chemical exposure on a victim?

One of the primary signs of chemical exposure in a victim is respiratory distress or difficulty breathing. This symptom is especially critical because many hazardous materials can irritate or damage the respiratory system when inhaled. Chemicals may cause inflammation in the airways, leading to symptoms such as coughing, wheezing, and shortness of breath. Given that the respiratory system is one of the first systems to react to airborne toxins, identifying respiratory distress promptly is essential for effective treatment and intervention.

Other potential signs of chemical exposure, such as skin rashes, fatigue, and nausea, can also occur, but they are not as immediate or as crucial as respiratory symptoms in acute cases of exposure. In many hazardous situations, the ability of a victim to breathe properly can be life-threatening, making the recognition of this symptom a top priority for responders.
