Environmental Issues About Electric Forklift Batteries
The electric lift truck is usually considered more stable and safe than gas and diesel powered internal combustion engines. Both gas and diesel engines pose a fire risk and emit harmful exhaust toxins. The electric forklift is not without is hazards though. They have rechargeable batteries as their source of power, and batteries can present risks to the natural environment as well as to personal safety. There are hazards associated with the disposal, storage, use and manufacture of rechargeable batteries for forklifts.
Manufacturing
The lift truck battery consists of lead plates being placed in a sulfuric acid solution, which are known as lead-acid rechargeable batteries. Lead is toxic that, when utilized in manufacturing processes, poses hazards to the quality of water due to runoff and drainage. When lead enters a water system it could lead to a variety of health issues to human beings and can even be fatal. The sulfuric acid used in lift truck batteries is detrimental to skin and could cause severe burns. Sulfuric acid also produces noxious fumes that could cause damage to human beings and the environment.
Regular Storage and Use
Lead-acid batteries could produce hydrogen gas as a chemical byproduct when recharging. When recharging batteries for a forklift or any other kinds of vehicle, heat, flames, sparks and smoking must be kept well away from the recharging place. The flammable hydrogen could cause an explosion if ignited by flame or heat.
Sulfuric acid in the batteries could cause chemical burns if it comes into contact with bare skin. This is not a problem during normal use of the battery, but if a battery is punctured or damaged, the acid could leak or spray, potentially burning anyone who is nearby.
Disposal
Incorrect disposal of lead-acid batteries should always be avoided. These batteries should be recycled properly or reused in new batteries so that the sulfuric acid can either be neutralized or recycled. In order to prevent the serious environmental consequences of improper disposal, all lead-acid batteries sold or purchased within the United States include a "core charge" which would just be returned if the used battery is turned in.
