Is Lithium Grease Flammable?

Lithium grease is a commonly used lubricant in various industries and household applications. It is a multi-purpose grease known for its excellent lubricating properties and wide temperature range. But when it comes to safety concerns, one question often arises: is lithium grease flammable? Let’s dive into the details to find out the answer.

Lithium Grease Background

Lithium grease is a type of grease that is made by combining lithium soap with mineral or synthetic oil. This combination forms a thick and sticky lubricant with excellent mechanical properties. It is widely used in automotive, marine, and industrial applications for lubricating various components, such as bearings, hinges, and gears.

Flammability of Lithium Grease

Lithium grease, in its pure form, is not flammable. The basic composition of lithium grease, which is lithium soap and oil, does not possess significant flammability properties. However, caution should be exercised when using lithium grease near open flames or in environments with high heat sources, as the oil in the grease can vaporize and potentially cause combustion.

Combustion Temperature

The combustion temperature of lithium grease depends on the type of oil used in its composition. Most lithium greases have a high flash point, which is the minimum temperature at which the grease vapors can ignite when exposed to an open flame or spark. This means that lithium grease requires a relatively high temperature for combustion to occur.

Precautions to Ensure Safe Use

While lithium grease is generally considered safe, it is important to take certain precautions to ensure its safe use:

  • Keep lithium grease away from open flames or sparks to prevent any potential fire hazards.
  • Store lithium grease in cool, dry places away from direct sunlight or heat sources to minimize the chances of oil vaporization.
  • Avoid excessive heat exposure, as it can lead to changes in the grease composition and reduce its lubricating properties.
  • Read and follow the manufacturer’s instructions and safety guidelines to understand any specific precautions related to the particular lithium grease product you are using.

Fire and Safety Standards

Many lithium grease manufacturers ensure that their products meet certain fire and safety standards. They often conduct tests to determine the flash and fire points of their greases, ensuring that they are safe for use in various environments. This information is usually provided on the product label or safety data sheet (SDS).


In conclusion, lithium grease is generally not flammable, but caution should be exercised when using it in potentially hazardous environments. While the grease itself does not pose a significant flammability risk, the oil within it can vaporize and potentially combust when exposed to high temperatures or open flames. To ensure safe use, always follow the manufacturer’s guidelines and store the grease properly. By taking these precautions, you can safely enjoy the benefits of lithium grease’s excellent lubricating properties.

If you have any doubts or concerns about the flammability of a particular brand or type of lithium grease, it is recommended to consult the manufacturer or refer to the relevant safety information provided.
