A flammable liquid is a liquid with flash point of not more than 60.5 °C (141 °F), or any material in a liquid phase with a flash point at or above 37.8 °C (100 °F) that is intentionally heated and offered for transportation or transported at or above its flash point in a bulk packaging.

2017年6月22日 · Class 3 Flammable liquids. Class 3 covers flammable liquids, which includes some molten solid substances and liquid desensitized explosives. Substances are divided into different packing groups according to the degree of danger they present to transportation.

2025年1月14日 · Class 3 flammable liquids are categorized based on their flash point and boiling point, which are key factors in determining the fire risk they pose. A liquid is classified as Class 3 if it has a flash point at or below 60°C (140°F) and a boiling point above 35°C (95°F).

2019年5月19日 · The red and white striped sign indicates a flammable solid. The half white, half red sign indicates that a material could spontaneously combust. A dangerous when wet sign, which is blue, indicates that a material could suddenly become flammable or emit toxic gas if exposed to water.

These signs have oxygen written on them and a graphic of an “O” with flames. White White indicates poisonous and biohazardous substances like dyes, acids, aerosols and medical waste. For toxic materials, the sign will be labeled poison, PG III (PG = packing group) or inhalation hazard with a skull-and-crossbones image.

A flammable liquid (Class 3) means a liquid having a flash point of not more than 60.5°C (141°F), or any material in a liquid phase with a flash point at or above 37.8°C (100°F) that is intentionally heated and offered for transportation or transported at or above its flash point in a bulk packaging, with the following exceptions:

2018年7月10日 · Class 3 flammable liquids include commonly shipped hazardous materials like gasoline and paint. Find out what to know to safely transport them here.

2024年4月10日 · Class 3 covers flammable liquids. This also includes material classified as combustible liquids. These are liquids that have a flash point of not more than 60 °C (140 °F), as well as solids heated to liquid phase with a flash point at or above 37.8 °C (100 °F).

Flammable liquids are: A liquid having a flash point of = 60.5° C (141° F) Any material in a liquid phase with a flash point = 37.8° C (100° F) that is intentionally heated and offered for transport or transported at or above its flash point in bulk packaging.

In addition to complying with 49 CFR §172.519, the background color on the FLAMMABLE placard must be red. The symbol, text, class number and inner border must be white. The word “GASOLINE” may be used in place of the word “FLAMMABLE” on a placard that is displayed on a cargo tank or a portable tank being used to transport gasoline by highway.
