Which physical property related to flammability is NOT typically found on an SDS?

• A. Auto-ignition temperature
• B. Flammable limits
• C. Melting point
• D. Flash point

Answer: (C)

The melting point is not typically associated with flammability and is often not included on a Safety Data Sheet (SDS) in the context of fire hazards. The melting point refers to the temperature at which a solid becomes a liquid, which is more relevant to the substance's state change rather than its ability to catch fire or contribute to combustion. In contrast, other properties like auto-ignition temperature, flammable limits, and flash point are critical for understanding a material’s flammability. The auto-ignition temperature indicates the temperature at which a substance will ignite without an external source of ignition. Flammable limits define the concentration range of a substance in air that can ignite, and the flash point is the lowest temperature at which vapors of a substance can ignite when exposed to a flame or spark. Each of these properties plays a vital role in assessing the fire hazard potential of a chemical, which is why they are included in SDS documentation.
