🔍 Key Concepts

• Properties and hazards of ammonia gas (flammability, toxicity, how it reacts with flame/heat) • How each device works: litmus paper, sulphur candle, halide torch • Why open flames or hot surfaces may be dangerous in a leak environment

💭 Think About

• Which option involves the least risk of ignition or chemical reaction with leaking ammonia? • Does ammonia require a chemical indicator or a flame-based detector, and what are the safety implications of each? • If you were standing in a space where you suspect an ammonia leak, which device would you feel safest using near a potentially flammable/toxic gas cloud?

✅ Before You Answer

• Identify which devices use an open flame or high heat and which do not • Recall that ammonia can form flammable mixtures with air under certain conditions • Check which method is typically used as a chemical indicator paper rather than a combustion-based detector
