To put out a grease fire, you should use a _____ _____ or the ansul system.

Using a fire extinguisher specifically designed for grease fires is the most effective and safe method to extinguish such fires. Grease fires, often originating from cooking oils, require a class B fire extinguisher that can safely handle flammable liquids. These extinguishers work by smothering the fire, which cuts off the oxygen supply and helps to cool the burning material, preventing re-ignition.

It is crucial to avoid using water, as this can cause the grease to splatter and spread the fire further, making the situation worse. Likewise, while a fire blanket can be beneficial for certain types of fires, it is not as effective for large grease fires or those that are particularly intense. The ansul system, which is a type of automated fire suppression, is specifically designed for kitchen hazards, reinforcing the need for proper training and equipment in managing these kinds of emergencies effectively.
