Final answer:
The statement is false. While flammable, toxic, and reactive materials can cause serious accidents, other factors should also be considered.
Step-by-step explanation:
Hazardous materials can cause accidents if they are mishandled or if proper safety precautions are not followed. For example, certain chemicals can be harmful if inhaled as fumes, even if they are not flammable, toxic, or reactive. Likewise, handling flames or heat plates without caution can lead to accidents, even if the materials being used are not inherently dangerous.
It's important to always follow safety instructions and guidelines when working with any materials in order to avoid accidents and ensure a safe environment.
