Question 36 TK01 - Tank Vessel Assistant - Dangerous Liquids

The Correct Answer is A. **Explanation for A (suspension of breathing):** When providing first aid, the immediate priority is to address life-threatening conditions according to the ABCs (Airway, Breathing, Circulation). Gas poisoning (e.g., carbon monoxide) directly interferes with the body's ability to transport or utilize oxygen, which can quickly lead to respiratory arrest (suspension of breathing). If the victim is not breathing, irreversible brain damage or death will occur within minutes. Therefore, checking for and immediately addressing the suspension of breathing is the single most critical step in initial first aid for gas poisoning. **Why other options are incorrect:** * **B) cold and moist skin:** This is a symptom often associated with shock or severe hypotension. While serious, it is a secondary manifestation of the physiological distress, not the most immediate life-threatening problem requiring intervention before addressing breathing. * **C) slow and weak pulse:** Changes in pulse rate and strength (circulation) are important, but checking for effective breathing (A) takes precedence. If the victim is not breathing, fixing the circulation will be futile. Furthermore, in many cases of severe gas poisoning, the heart rate may initially be rapid (tachycardia) before slowing down. * **D) unconsciousness:** Unconsciousness is a very common and serious sign of severe gas poisoning. However, a person can be unconscious yet still breathing. The most immediate life threat is the cessation of breathing itself, which must be verified and corrected before focusing on the victim’s level of consciousness.
