How does fire happen? Answers. 1  Oxygen+Heat+Fuel=combustion or fire. Fire is the rapid oxidation of a material in the chemical process of combustion, releasing heat, light, and various reaction products. The flame is the visible portion of the fire and consists of glowing hot gases.

Fire behaviour Fire behaviour refers to the manner in which fuel ignites, flame develops and fire spreads. In wildland fires, this behaviour is influenced by how fuels (such as needles, leaves and twigs), weather and topography interact. Once a fire starts, it will continue burning only if heat, oxygen and more fuel are present.

Fire extinguisher A fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user, or otherwise requires the expertise of a fire brigade. Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent which can be discharged to extinguish a fire. Fire extinguishers manufactured with non-cylindri

User Contributed Dictionary A firestorm is a conflagration which attains such intensity that it creates and sustains its own wind system. It is most commonly a natural phenomenon, created during some of the largest bushfires, forest fires, and wildfires. The Great Peshtigo Fire and the Ash Wednesday fires are two examples of a firestorm.

Fire Investigation Nature & Chemistry of Fire. Fire occurs due to the exothermic reaction of combustion (burning), producing heat and light. In order for a fire to occur, three vital components must be present: a fuel source, an oxidant (O2) and a sufficient amount of energy in the form of heat. Together these make up the fire triangle. A fourth factor can also be described – a self-sustaining chemical chain reaction – to produce the fire tetrahedron. The absence of any of these conditions will result in a fire not starting or extinguishing through smothering (oxygen removal), cooling (heat removal) or starving (fuel removal).

"Use of the word ""conservative""" I think what he's suggesting is that we often use the word conservative to imply that we're assigning values that we know to be too large (or too small, depending on the situation), when in reality we simply don't have an accurate handle on the real value.E: Use of the word conservative. What you are really trying to say is that you are utilizing a biased parameter that errs on the side of a higher factor of safety or an upper limit on settlement.

- -- For me, life can be defined by it's most basic building block -- a cell. If something does not contain at least one cell, it is not alive. Fire does not contain cells. -- Living things contain DNA and/or RNA, proteins which contain the basic information cells use to reproduce themselves. Fire does not contain DNA or RNA. -- Living things are made of matter, and you can weigh them. It may be hard to measure the weight of one bacteria, but you get the point.

Vinyl Siding Cost 1 Estimates are based on the exterior square feet of your home. 2  For example, if your home was 10' tall, 40' long and 30' wide, it could be a 1,200 square foot home with 10*(40+40+30+30)=1,400 exterior square feet, which could take roughly 14 10'x10' squares of vinyl. If you already have siding, it will need to be removed, which can cost $1,000-$3,000 to remove. 2  Two of the top manufacturers are CertainTeed and Crane. 3  The Crane Website can help you locate a contractor near you who can install their siding.

Fire ecology Fire ecology is concerned with the processes linking the natural incidence of fire in an ecosystem and the ecological effects of this fire. Many ecosystems, particularly prairie, savanna, chaparral and coniferous forests, have evolved with fire as a necessary contributor to habitat vitality and renewal.Many plant species in naturally fire-affected environments require fire to germinate, establish, or to reproduce.any ecosystems, particularly prairie, savanna, chaparral and coniferous forests, have evolved with fire as a necessary contributor to habitat vitality and renewal.

What is a firewall? A firewall is a system designed to prevent unauthorized access to or from a private network. You can implement a firewall in either hardware or software form, or a combination of both. Firewalls prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. The firewall capabilities lie in the fact that a proxy can be configured to allow only certain types of traffic to pass (e.g., HTTP files, or web pages). 2  A proxy server has the potential drawback of slowing network performance, since it has to actively analyze and manipulate traffic passing through it.
