أخطار الكهرباء وكيفية التعامل معها: الطاقة الكهربية

The video explains that water is not suitable for extinguishing all types of fires due to its conductivity and potential to worsen certain situations. It highlights the dangers of using water on electrical, oil, and petroleum fires. Instead, fire extinguishers, primarily containing carbon dioxide, are recommended for these types of fires. The video emphasizes the importance of using the correct method to ensure safety and effectiveness in firefighting.
