What DOT class are flammable liquids?

Hazard Class 3
Hazard Class 3 – Flammable Liquids Flammable liquids have a “flash point” of 140°F or less. A flash point is the temperature when an ignition source near the liquid can ignite the vapors. Examples of flammable liquids include the following: Gasoline.

What are the DOT hazard classes?

DOT Hazard Classification System

  • Class 1 – Explosives.
  • Class 2 – Gasses.
  • Class 3 – Flammable liquids (and Combustible liquids [U.S.])
  • Class 4 – Flammable solids; Substances liable to spontaneous combustion; Substances which, on contact with water, emit flammable gases.
  • Class 5 – Oxidizing substances and Organic peroxides.

What is a DOT flammable liquid?

A flammable liquid is defined at 49 CFR 173.120(a) as a liquid with a flash point ≤60˚C (≤140˚F), or any liquid in bulk packaging with a flashpoint ≥37.8˚C (≥100˚F) that is intentionally heated and transported above its flashpoint (some exceptions).

What is a Class 2.1 substance?

(a) Division 2.1 (Flammable gas). For the purpose of this subchapter, a flammable gas (Division 2.1) means any material which is a gas at 20 °C (68 °F) or less and 101.3 kPa (14.7 psia) of pressure (a material which has a boiling point of 20 °C (68 °F) or less at 101.3 kPa (14.7 psia)) which –

Is gasoline a Category 1 flammable liquid?

Class IA liquids are liquids that have flash points below 73 °F (22.8 °C) and boiling points below 100 °F (37.8 °C). Additionally, unstable flammable liquids are treated as Class IA liquids. Typical Class IB liquids include acetone, benzene, ethyl alcohol, gasoline, and isopropyl alcohol.

What is a Category 4 flammable liquid?

Category 4 shall include liquids having flashpoints above 140 °F (60 °C) and at or below 199.4 °F (93 °C).

How do you classify hazardous materials?

TYPES OF HAZARDOUS MATERIALS

  1. Class 1: Explosives.
  2. Class 2: Gases.
  3. Class 3: Flammable Liquids.
  4. Class 4: Flammable Solids.
  5. Class 5: Oxidizing Substances, Organic Peroxides.
  6. Class 6: Toxic Substances and Infectious Substances.
  7. Class 7: Radioactive Material.
  8. Class 8: Corrosives.

Is gasoline a Class 3 flammable liquid?

Many of the products that we use on a regular basis are classified as class 3 flammable liquids. Gasoline and items that contain gasoline or gasoline fumes are some of the most common examples.

What is a Class 2 Division 2.1 hazardous material?

Division 2.1: Flammable Gases. These gases are known to ignite on contact with ignition sources. This includes acetylene, hydrogen, propane and many others. Division 2.2: Non-Flammable, Non-Toxic Gases.

What are Class A hazards?

What is a Class A – Compressed Gas? Any material that is normally a gas which is placed under pressure or chilled, and contained by a cylinder is considered to be a compressed gas. These materials are dangerous because they are under pressure.

What is an example of a category 1 flammable liquid?

Examples of Category 1 Flammable Liquids include: Diethyl Ether. Pentane. Ligroin. Heptane.

What do you need to know about class 3 flammable liquids?

Lastly, all shipments of class 3 flammable liquids must be labeled appropriately. Class 3 flammable liquid labels should be affixed to all small containers to let anyone handling them know that the materials contained within are dangerous.

What is the definition of a flammable liquid?

  A flammable liquid is defined at 49 CFR 173.120(a) as a liquid with a flash point ≤60˚C (≤140˚F), or any liquid in bulk packaging with a flashpoint ≥37.8˚C (≥100˚F) that is intentionally heated and transported above its flashpoint (some exceptions).

Are there any exceptions for combustible liquid hazardous materials?

US DOT Exception for Combustible Liquid Hazardous Materials. You may be familiar with several hazardous materials such as diesel fuel or kerosene that, depending on their formulation, may have a slightly higher flashpoint than more obvious flammable liquids such as gasoline.

What are the flash points of a flammable liquid?

It also contains molten materials in their liquid phase with flash points that are no greater than 37.8 degrees Celsius or 100 degrees Fahrenheit. Because there are numerous products and materials that fit into this class, understanding how to properly label and transport them is extremely important.
