Here's why:

* Chemical Composition: Sodium acetate (CH3COONa) is a salt formed from the reaction of acetic acid (vinegar) and sodium hydroxide (lye). It's a stable compound with a high melting point and doesn't readily combust.

* Fire Hazard: It's classified as a non-hazardous material in terms of flammability.

However, it's important to note:

* Hot Solutions: When heated to high temperatures, solutions of sodium acetate can become flammable due to the presence of water and other volatile compounds.

* Reaction with Oxidizers: Sodium acetate, when in contact with strong oxidizers like potassium permanganate, can react vigorously and generate heat, potentially leading to a fire.

In summary: While sodium acetate itself is not flammable, it's crucial to be aware of potential hazards associated with its use in certain conditions.
