Battery Hazards

As batteries are energy warehouse devices, they are prone to make many threats to human life and safety. A short circuit is one of the coarse Battery perils. The most foremost reason for short circuits is overcharging or over discharging. Other causes for cell short circuits include faulty separators, aggregation of lead particles or other metals between both the plates, buckling of the plates and immoderate sediments in the bottom of the jar.

Battery Hazards

Another Battery hazard is the generation of gasses. "Battery gassing" is a normal stock of charging. passage of electricity through water dissociates the water into hydrogen and oxygen. These are the gases that emanate from an open cell battery. When hydrogen reaches an intensity of 4% in air, it can be explosive. Therefore, it is primary that the area is well ventilated and there is no occasion of open flame.

High-power lithium cells should be maintained with greatest care because a short circuit can lead to internal overheating thereby making an explosion or battery rupture. These lithium cells are more sensitive to bodily stress than alkaline batteries and are generally found in today's cellular phones. Electrical burns, strains, and sprains are some of the coarse hazards that arise when servicing, charging, or jumping the coarse lead-acid battery. Lead-acid batteries can also cause danger when the acid spills out. For these types of batteries, the occurrence of short circuit while replacing can be minimized by disconnecting the earth lead first and replacing them last. One way to reduce battery hazards in a vehicle is to switch off all the vehicle electrical tool before the charger leads are removed from the vehicle.
