प्रश्न
Briefly explain the various causes of fire.
उत्तर
Fires usually occur due to poor wiring and faulty electrical equipment, leakage of cooking gas or a carelessly thrown matchstick. The most common cause of a fire in a building is poor electrical wiring and faulty equipment. Electrical wiring must be regularly checked. If the wiring is worn-out, it must be replaced immediately by standard quality wires and electrical fittings to avoid any short-circuit. Fire can also be caused due to gas leakage. Gas pipes, regulators and stoves should be regularly checked to ensure there is no leakage. Regular maintenance checks in gas pipelines should also be mandatory. Fire is also commonly caused by carelessly thrown matches and cigarettes. It is also one of the common causes of forest fires. There is also fire-related disasters in areas where wood is used in construction activities. The loss of life is more if a fire breaks out in crowded areas.
