🔍 Key Concepts

• Toxic gas exposure and how it affects breathing vs. skin/contact • Basic first aid priorities: airway, breathing, circulation (ABCs) • Difference between treating inhalation of fumes and treating a liquid chemical spill on the skin

💭 Think About

• Ask yourself: What is the very first priority when someone has inhaled a toxic vapor like ammonia? • Which action directly reduces the person’s continued exposure to the harmful vapors? • Which option, if done first, would most quickly help the lungs and breathing, rather than just treating skin or general comfort?

✅ Before You Answer

• Verify whether ammonia in this question is mainly a vapor inhalation problem or a skin-contact problem • Check which option immediately removes the victim from the harmful atmosphere or improves the air they are breathing • Eliminate any choices that are more about comfort than about restoring or protecting breathing
