The Annual Fire Crisis in Northern India

Every summer, Northern India faces a deadly cycle of fires. Recently, on June 3, a blaze in a building in Delhi's Hauz Rani claimed the lives of 23 individuals, while a fire in a multi-story building in Lucknow on June 22 resulted in the deaths of 15 young people. Both incidents are attributed to short circuits and negligence regarding safety regulations in the buildings.

What Exactly is a Short Circuit?

A short circuit occurs when the positive and negative charges in electrical wires connect, allowing current to flow. As current travels through a wire, it generates some heat. Wires can withstand a limited amount of heat, but a short circuit happens when the current finds an unexpected, easier path, causing electricity to flow rapidly. This rapid flow generates enough heat and sparks to ignite nearby materials. Although modern homes are equipped with circuit breakers that cut off electricity, fires can sometimes start quietly, eluding detection by these breakers.

Loose Connections: A Hidden Fire Hazard

Fires often do not ignite suddenly; they typically start slowly. When heavy appliances like air conditioners or geysers are connected with thin wires, or if the connection between two wires is loose, resistance increases. The heat causes the connection to loosen further, creating a gap as thin as a hair between the wires. Electricity jumps across this gap, producing continuous sparks. This cycle continues until a severe fire breaks out.

Wires Designed for 33 Degrees Facing 45 Degrees Heat

According to reports, most electrical equipment and wires in India are designed to operate at a normal temperature of 33 degrees Celsius. However, during summer, temperatures in Northern India often exceed 45 degrees. This extreme heat reduces the wires' capacity to conduct electricity, causing them to heat up quickly and potentially melt. In simpler terms, during summer, wires are under additional stress from the external heat, while heavy appliances like air conditioners and refrigerators run continuously.

Are Air Conditioners Time Bombs?

Incidents of air conditioners exploding have been increasingly reported in various apartments across Delhi-NCR. Air conditioners require a significant power boost to start, which is provided by a component known as a capacitor. Prolonged exposure to sunlight and continuous operation can weaken this capacitor, putting pressure on the motor, which may then burn out. Additionally, the constant vibrations from the air conditioner can loosen internal wires, increasing the risk of a short circuit. Many modern air conditioners use flammable gases like R-32 or propane. If there is a gas leak from the outdoor unit and a small spark occurs due to a short circuit, it can lead to a massive explosion.
