Storage of flammable liquids must occur in either the original container from the manufacturer, or in approved containers as illustrated in Table 1 of this fact sheet.
"Flammable liquid" means any liquid having a flashpoint at or below 199.4 °F (93 °C). Flammable liquids are divided into four categories as follows:
Flash point < 23°C and initial boiling point ≤ 35°C (95°F)
Flash point < 23°C and initial boiling point > 35°C (95°F)
Flash point ≥ 23°C and ≤ 60°C (140°F)
Flash point ≥ 60°C (140°F) and ≤ 93°C (200°F)
When liquid with a flashpoint greater than 199.4 °F (93 °C) is heated for use to within 30 °F (16.7 °C) of its flashpoint, it shall be handled in accordance with the requirements for a Category 4 flammable liquid.
Fire Area: A "fire area" is an area of a building separated from the remainder of the building by special construction. This area has a fire resistance of at least 1 hour and has all communicating openings properly protected by an assembly that also has a fire resistance rating of at least 1 hour.
Flammable Liquid Storage Outside of a Flammable Storage Cabinet: The maximum quantities of flammable liquids that can be stored outside of a flammable storage cabinet are listed in the Table below:
