What are Class 3 Flammable Liquids?

Class 3 flammable liquids are substances that can easily ignite and sustain combustion. According to the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS), Class 3 includes liquids, or mixtures of liquids, or liquids containing solids in solution or suspension (for example, paints, varnishes, lacquers, etc., but not those that, due to other hazard characteristics, have been assigned to another class) which give off a flammable vapor at or below 60 °C (140 °F) closed-cup test, or are carried or offered for transport at a temperature at or above that temperature.

• Flash Point: This is the temperature at which a liquid produces enough vapor to ignite in the presence of an ignition source. Class 3 liquids have a flash point of 140°F (60°C) or below.
• Examples: Common examples include gasoline, ethanol, acetone, kerosene, and various paints and solvents.
• Hazards: The primary hazards include fire, explosion, and potential health risks through inhalation, skin contact, or ingestion.

Key Properties and Characteristics

Understanding the specific properties of Class 3 flammable liquids is crucial for safe handling. Each liquid has unique characteristics, but several factors are common:

• Volatility: The rate at which a liquid vaporizes. Higher volatility means a greater risk of vapor accumulation and ignition.
• Vapor Density: Whether the vapor is heavier or lighter than air. Heavier-than-air vapors can accumulate in low-lying areas, increasing the risk of fire.
• Ignition Temperature: The temperature at which a substance will spontaneously ignite without a direct ignition source.
