2. Implement real-time telemetry tracking systems.

3. Train drivers in emergency management and handling of hazardous loads.

4. Report incidents to authorities without delay.

According to current regulations, transporting hazardous substances without meeting requirements can result in administrative fines, suspension of operations, and criminal liability for negligent homicide or injury. Authorities will determine whether there was a lack of maintenance, overloading, or negligent handling.

Social and psychological support

Fire and burn survivors require comprehensive care: medical support, physical rehabilitation, and specialized psychological care. Local NGOs and public programs offer assistance; family members should inquire at hospital units for information.

Final recommendations for authorities

• Make the research process transparent.
