What is the safety risk when heating alcohol directly with a flame?

• A. Fire may be produced
• B. It may cause rust
• C. It may cause odor
• D. It may cause color change

Answer: (A)

Heating alcohol directly with a flame is dangerous because alcohol is highly flammable and readily forms vapors that can ignite in air. When you heat it, more vapor is produced, and these vapors can reach the flame and catch fire, causing a flare-up or a spreading fire. This isn’t about rust, odor, or color changes—the immediate safety risk is the ignition of the vapors and the fire that can result.
