If a fire extinguisher runs out of material, what is another way to try to extinguish the fire?

Throwing sand on a fire is effective because it can suffocate the flames by cutting off the oxygen supply. Sand is specifically useful for certain types of fires, especially those involving flammable liquids or materials, as it can form a barrier that prevents oxygen from reaching the fire, thereby helping to extinguish it.

Water can sometimes be problematic if the fire involves flammable liquids or electrical components, as it may spread the fire or create hazardous situations. Using a blanket can also be a valid method for smaller fires but is generally less effective than sand in terms of smothering and suffocating a fire. Calling for help is crucial in some situations, especially when the fire is out of control, but it does not contribute to extinguishing the fire immediate needs if other means are available.
