Final answer:
The correct answer is option 3) Flammable Liquids. Class 3 flammable liquids have a flash point below 60 °C (140 °F) and are labeled with a red diamond-shaped hazard class label.
Step-by-step explanation:
Class 3 flammable liquids are materials that can catch fire easily at normal working temperatures. They have a flash point below 60 °C (140 °F) and include substances such as gasoline, ethanol, and acetone. These liquids are labeled with a red diamond-shaped hazard class label that indicates they are flammable.
Flammable liquids can pose a serious fire hazard and must be handled and stored safely to prevent accidents. It is important to follow proper safety protocols and procedures when dealing with flammable liquids to ensure the safety of yourself and others.
The material safety and handling instructions provided by the United States Department of Transportation (DOT) and the Environmental Protection Agency (EPA) categorize organic solvents as flammable due to their volatility. Furthermore, solvent vapors can pose a significant risk since they are heavier than air and can lead to potential flash fires even in seemingly empty containers, making the proper classification and labeling of these wastes vital for safe handling.
