Fire - one of the most dangerous hazards.The causes of the fire are largely dependent on human negligence, but there are times when human activity is not related to fire.In order to understand why there are fires, we consider them in detail.
Classification of fires at the place of occurrence
1. fire in apartments, houses and other premises.
main cause of a fire in the place where people live - negligence.May lead to fire:
- Games with fire.Often the perpetrators are children left unattended.To eliminate this cause kids from an early age should be told about the dangers of fire.In addition, children should not be left without reliable supervision, and all flammable objects should be removed and hidden.
- wiring fault.It may be for different reasons.It is therefore necessary at least once a month inspect all the wires in the house, sockets, electrical appliances and wiring.
- illegal or negligent operation of the gas tanks, fireplaces, stoves.Using these devices, the tenants must abide by the law and special care.
- gas leak.Check all gas appliances need to systematically.
2. Fires in offices, factories.
Statistics found that the main cause of a fire in the office and industrial enterprises - failure to comply with safety regulations:
- Enterprise is not equipped with equipment for fire fighting: shields, fire extinguishers, fire cabinets.
- flagrantly violate building codes and other standards.
- During use defective equipment.
- improperly stored flammable or other flammable substances.
- violated technologies, especially during welding, electrical, etc.works.
should be noted that each listed cause of the fire is also a consequence of the human factor.
3. Forest and steppe fires
causes of forest fires is also often dependent on people, although there are other factors.Forest and steppe can ignite:
- a result of a lightning strike.
- due to natural underground peat fire.
These cases may be the culprits of natural fires, but not often.The most common cause of fire in the wilderness or a forest - the same human factor:
- Bonfires.
- Burning stubble.
- Leaving unquenched cigarette butts.
- Broken glass (refracting the sun's rays, the glass can work as a lens and cause a fire).
- arson.
Despite the fact that the quenching of all fires - a very difficult task, especially difficult is putting out the fire in the forest and steppe.
even more difficult to extinguish underground fires.Some ignition of coal or peat can be naturally start without human intervention, but because of the chemical reactions.Such fires are virtually impossible to extinguish.Today, thousands of underground fires are raging in America, India, China and other countries.
For example, a fire in the American town of Centralia can not put out since 1962.The fire which started in the Chinese mine Lyuhuangou in 1874, were able to put out only in 2004.
