Furthers risks include the occurrences of backdrafts. Backdrafts occur when there is a large amount of oxygen introduced to an oxygen-depleted fire(citation here). If a fire is compartmentalized and most or all of the oxygen has been burned up, there is a high risk of backdraft if something such as a window or door is opened. Introducing oxygen to a low burning fire can be devastating as it will ignite all of the oxygen along the way(citation here). It can also be heard from miles away as it has a concussive blast that adds to the effect. Firefighters need to have extreme communication at all times on the fire ground as one broken window at the wrong time could seriously harm anyone operating on the building.
