In addition, they are tightly woven, preventing air from passing through them. The 'flashpoint' is another temperature at which a material may ignite. So, if a fire runs out of fuel, it will smoulder out; if you can cool a fire down it will lose heat and go out; and if the oxygen is removed it will suffocate. In addition to reducing a fire's temperature, water may also help in its containment. What deficiency causes a preterm infant respiratory distress syndrome? It helped us develop more things and made us grow to where we are today.
