What is the definition of a chemical that resists ignition or the spread of fire when applied to materials?

1. Fire barrier

2. Fire retardant

3. Flame suppressor

4. Fire inhibitor

The correct answer is: Fire retardant

The term associated with a chemical that resists ignition or the spread of fire when applied to materials is "fire retardant." Fire retardants are substances designed to slow down or prevent the combustion process in materials, such as textiles, plastics, or building materials. By either releasing chemicals that inhibit the fire's ability to ignite or promoting the formation of a protective barrier during combustion, these substances play a crucial role in fire safety and prevention. Understanding this definition helps in differentiating it from terms like "fire barrier," which generally refers to a physical structure that prevents the spread of fire, rather than a chemical treatment. Similarly, "flame suppressor" implies a more active role in extinguishing flames rather than preventing ignition, and "fire inhibitor" could refer to a broader range of substances that might impede fire but not specifically in the context of treated materials. Fire retardants are specifically engineered for their unique properties in reducing flammability and enhancing safety in various applications.
