The Correct Answer and Explanation is :
Correct Answer: Flammable liquids
Explanation:
Flammable liquids are one of the leading causes of laboratory fires due to their volatility and the ease with which they can ignite when exposed to a heat source, spark, or open flame. These liquids often have low flash points, meaning they can produce enough vapor to form an ignitable mixture with air at relatively low temperatures.
Key Reasons Why Flammable Liquids Pose a High Fire Risk:
- Volatile Nature: Flammable liquids, such as ethanol, acetone, and toluene, evaporate quickly at room temperature, releasing vapors that can easily ignite.
- Wide Use: These liquids are commonly used in laboratories for cleaning, experiments, and reactions, making them pervasive in the lab environment.
- Improper Storage: Improper storage, such as leaving containers open or storing them near heat sources, can lead to accidental ignition.
- Spills and Leaks: Spilled flammable liquids increase surface area and vapor production, creating a high risk of ignition.
- Ignition Sources: Common lab equipment, such as Bunsen burners, electrical devices, or even static electricity, can ignite vapors from flammable liquids.
Preventive Measures:
- Proper Storage: Store flammable liquids in approved safety cabinets and containers designed to minimize vapor release and resist fire.
- Ventilation: Ensure proper ventilation to prevent the accumulation of flammable vapors in the air.
- Avoid Open Flames: Do not use open flames near flammable liquids.
- Use Spill Control Kits: Address spills immediately using proper absorbent materials and follow cleanup protocols.
- Labeling and Segregation: Clearly label flammable liquids and segregate them from incompatible chemicals, such as oxidizers, to prevent dangerous reactions.
Understanding and addressing the risks associated with flammable liquids is critical in preventing laboratory fires and ensuring a safe working environment.
