Which of the following does NOT classify a chemical as hazardous?

A chemical is classified as hazardous based on certain characteristics that can pose risks to health or the environment. Ignitable, corrosive, and toxic are all properties that indicate the potential dangers associated with a chemical.

Ignitable substances can easily catch fire and pose a fire hazard. Corrosive chemicals can cause degradation of materials, including skin or other surfaces, leading to physical harm. Toxic substances are harmful or fatal when ingested, inhaled, or absorbed through the skin, indicating their danger to health.

In contrast, non-reactive refers to materials that do not have a tendency to react chemically under typical conditions. This characteristic indicates a lower potential hazard, as it does not imply that the chemical poses significant risks through fire, corrosion, or toxicity. Therefore, non-reactive does not classify a chemical as hazardous, making it the correct answer in this context. Understanding these classifications is crucial for safe handling and application of chemicals, especially in pesticide usage.
