🔍 Key Concepts

• Ammonia (NH₃) as a refrigerant – common uses and safety data • Difference between toxicity, flammability, and explosiveness • How safety data sheets (SDS) describe ammonia’s hazards

💭 Think About

• Think about how ammonia is handled on board: What kind of personal protective equipment (PPE) and ventilation are required when working around ammonia systems? • If there is a leak in an ammonia refrigeration system, what are the main immediate dangers to personnel and the ship? • Does ammonia need special precautions regarding ignition sources, confined spaces, or both?

✅ Before You Answer

• Check whether ammonia is classified as toxic and what exposure does to the human body (eyes, lungs, skin). • Check whether ammonia is considered flammable, and under what concentration ranges in air. • Check whether ammonia is directly classified as explosive, or whether it only becomes explosive under special conditions, and how that compares with the other hazards listed.
