Q

People familiar with ammonia refrigeration systems become accustomed to its odor and may forget that the vapors have which of the following properties?

🔍 Key Concepts

• Toxicity of ammonia vapor at different concentrations • How ammonia behaves when it contacts moisture, such as perspiration or eyes • Whether ammonia is considered flammable or explosive under normal conditions

💭 Think About

• Think about what happens if someone breathes a small amount of ammonia versus a high concentration. Which is more likely to be immediately fatal? • Consider what ammonia does when it comes into contact with damp skin, eyes, or lungs. Does it just irritate, or can it cause chemical (caustic) burns? • Recall from safety data sheets: Is ammonia generally classified as a flammable gas that easily burns or explodes, or mainly as a toxic/corrosive gas with special behavior in confined spaces?

✅ Before You Answer

• Verify from a safety reference whether ammonia’s main hazard is toxicity, causticity, flammability, or a combination • Check if ammonia is readily flammable in open air, or only under certain concentration and ignition conditions • Confirm whether each individual statement (A, B, C) is factually correct for ammonia before deciding if they can all be true together
