Firefighters had to focus their efforts on saving the adjacent church instead of this burning building.

A fire burns due to the presence of three elements: fuel, oxygen and heat. This is often referred to as the fire triangle. Sometimes it is known as the fire tetrahedron if a fourth element is added: a chemical chain reaction which can help sustain certain types of fire.
The aim of firefighting is to deprive the fire of at least one of those elements. Most commonly this is done by dousing the fire with water, though some fires require other methods such as foam or dry agents. Firefighters are equipped with a wide variety of equipment for this purpose that include: ladder trucks, pumper trucks, tanker trucks, fire hose, and fire extinguishers.
While sometimes fires can be limited to small areas of a structure, wider collateral damage due to smoke, water and burning embers is common. Specific procedures and equipment are needed at a property where hazardous materials are being used or stored.
Structure fires may be attacked with either “interior” or “exterior” resources, or both. Interior crews, using the “two in, two out” rule, may extend fire hose lines inside the building, find the fire and cool it with water. Exterior crews may direct water into windows and other openings, or against any nearby fuels exposed to the initial fire. Hose streams directed into the interior through exterior wall apertures may conflict and jeopardize interior fire attack crews.
Buildings that are made of flammable materials such as wood are different from building materials such as concrete. Generally, a “fire-resistant” building is designed to limit fire to a small area or floor. Other floors can be safe by preventing smoke inhalation and damage. All buildings suspected or on fire must be evacuated, regardless of fire rating.
