What precaution should be taken with partially burned papers before disposal?

Partially burned papers can still pose a risk for combustion if they contain flammable materials or residual heat. Therefore, it's essential to examine them for flammability before disposal. This ensures that all potentially hazardous materials are identified and handled appropriately, preventing the chance of reignition which could lead to a larger fire. Assessing for flammability can include checking for smoldering edges, remaining heat, or the presence of any accelerants, making it a critical step in safe disposal practices. This precaution helps maintain safety not only for the person handling the materials but also in protecting the environment and surrounding area from possible fire hazards.
