Which action should be avoided when handling partially burned papers?

Keeping partially burned papers near flammable materials poses a significant risk as it can lead to re-ignition or the spread of fire. Partially burned materials often contain still-flammable components, and placing them in close proximity to other flammable items increases the likelihood of a fire hazard developing. Ensuring that such materials are kept away from anything that could ignite easily is a key aspect of fire safety.

In contrast, assessing the combustibility of the papers helps understand their potential risk; transporting them in a secure container prevents accidental ignition or scattering; and notifying others of their presence ensures that appropriate safety measures are taken by everyone nearby. Each of these actions contributes to a safer response in situations involving potentially hazardous materials.
