Fire safety

Fire safety is the set of practices intended to reduce the destruction caused by fire. Fire safety measures include those that are intended to prevent ignition of an uncontrolled fire, and those that are used to limit the development and effects of a fire after it starts.

Fire safety measures include those that are planned during the construction of a building or implemented in structures that are already standing, and those that are taught to occupants of the building.

Threats to fire safety are referred to as fire hazards. A fire hazard may include a situation that increases the likelihood of a fire or may impede escape in the event a fire occurs.

Fire safety is often a component of building safety. Those who inspect buildings for violations of the Fire Code and go into schools to educate children on Fire Safety topics are fire department members known as Fire Prevention Officers. The Chief Fire Prevention Officer or Chief of Fire Prevention will normally train newcomers to the Fire Prevention Division and may also conduct inspections or make presentations.

Fire

Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not included by this definition.

Fire is hot because conversion of the weak double bond in molecular oxygen, O₂, to the stronger bonds in the combustion products carbon dioxide and water releases energy (418 kJ per 32 g of O₂); the bond energies of the fuel play only a minor role here. At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different.

Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Fire has been used by humans for cooking, generating heat, light, signaling, and propulsion purposes. The negative effects of fire include hazard to life and property, atmospheric pollution, and water contamination. If fire removes protective vegetation, heavy rainfall may lead to an increase in soil erosion by water. Also, when vegetation is burned, the nitrogen it contains is released into the atmosphere, unlike elements such as potassium and phosphorus which remain in the ash and are quickly recycled into the soil. This loss of nitrogen caused by a fire produces a long-term reduction in the fertility of the soil, which only slowly recovers as nitrogen is "fixed" from the atmosphere by lightning and by leguminous plants such as clover.

Fire extinguisher

A fire extinguisher, or 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 (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the expertise of a fire department. Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent which can be discharged to extinguish a fire.

In the United States, fire extinguishers in all buildings other than houses are generally required to be serviced and inspected by a fire protection service company at least annually. Some jurisdictions require more frequent service for fire extinguishers. The servicer places a tag on the extinguisher to indicate the type of service performed (annual inspection, recharge, new fire extinguisher).

Catching Fire

Catching Fire is a 2009 science fiction young adult novel by American novelist Suzanne Collins, the second book in The Hunger Games trilogy. As the sequel to the 2008 bestseller The Hunger Games, it continues the story of Katniss Everdeen and the post-apocalyptic nation of Panem. Following the events of the previous novel, a rebellion against the oppressive Capitol has begun, and Katniss and fellow tribute Peeta Mellark are forced to return to the arena in a special edition of the Hunger Games.

The book was first published on September 1, 2009, by Scholastic, in hardcover, and was later released in ebook and audiobook format. Catching Fire received mostly positive reviews, with reviewers praising Collins' prose, the book's ending, and the development of Katniss's character. According to critics, major themes of the novel include survival, authoritarianism, rebellion, and interdependence versus independence. The book has sold more than 19 million copies in the U.S. alone.

A film adaptation of the novel was released on November 22, 2013.

Fire prevention

Fire prevention is a function of many fire departments. The goal of fire prevention is to educate the public to take precautions to prevent potentially harmful fires, and be educated about surviving them. It is a proactive method of reducing emergencies and the damage caused by them. Many fire departments have a Fire Prevention Officer.

In the general sense of preventing harmful fires, many aspects are discussed in the articles Fire protection and Fire safety.

Target audiences

Students

Students are often the primary target of fire prevention. Firefighters will visit schools and teach students the basics of fire prevention. Workshops should be conducted in schools for educating students for the effects of fires and how to deal with it and prevent fire

Senior citizens

Seniors have been identified as an "at risk" group, especially in hazardous situations. It is important that seniors have pre-planned their escape routes and have access to emergency exits, for example.

Landlords

In many jurisdictions, landlords are responsible for implementing fire prevention and fire safety measures in accordance with various laws.
