🔍 Key Concepts

• First aid for chemical burns to the skin • Properties and hazards of liquid ammonia refrigerant (cold burns, caustic effect) • Standard immediate response sequence before seeking medical care

💭 Think About

• In the first few seconds after exposure to a corrosive or freezing chemical, what action is usually recommended before anything else? • Which choice focuses on immediately reducing the chemical’s effect on your skin rather than long‑term treatment? • How do industrial safety data sheets (SDS) typically say to treat skin exposure to strong chemicals or refrigerants?

✅ Before You Answer

• Identify which option provides instant decontamination of the chemical from your skin. • Ask yourself which step would come first, before calling medical help or applying any medication. • Consider that liquid ammonia can both burn and freeze tissue – which action best limits further damage right away?
