When handling flammable solids, which practice is recommended?

• A. Storing them near heat sources
• B. Keeping them in airtight containers
• C. Igniting them to test their flammability
• D. Using them in poorly ventilated areas

Answer: (B)

Keeping flammable solids in airtight containers is the recommended practice because it minimizes the exposure of these materials to oxygen, which is essential for combustion. Airtight storage also helps contain any potential leaks or spills, reducing the risk of igniting a fire. Additionally, it protects the materials from environmental factors such as moisture, which can sometimes enhance flammability or create hazardous reactions.

Storing flammable solids away from heat sources is crucial for safety; otherwise, the risk of ignition increases. Igniting flammable solids to test their flammability poses an obvious danger and is not a safe practice. Working in poorly ventilated areas can lead to the accumulation of flammable vapors, increasing the risk of fire or explosion, further underscoring why using airtight containers for storage is the preferred method in managing flammable solids.
