Environmental Problems About Electric Lift Truck Batteries
The electric lift truck is generally considered more safe and stable compared to 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 could present risks to the natural environment as well as to personal safety. There are hazards connected with the disposal, storage, manufacture and use of rechargeable batteries for forklifts.
Manufacturing
The lift truck battery consists of lead plates being placed in a sulfuric acid solution, which are called lead-acid rechargeable batteries. Lead is a toxin that, when utilized in manufacturing processes, poses hazards to water quality due to runoff and drainage. Once lead enters a water system it could cause a variety of health issues to people and could even be fatal. The sulfuric acid used in lift truck batteries is detrimental to skin and could lead to severe burns. Sulfuric acid also produces noxious fumes that can cause damage to both the environment and to human beings.
Regular Storage and Use
Lead-acid batteries can produce hydrogen gas as a chemical byproduct when recharging. When recharging batteries for a lift truck or any other kinds of vehicle, sparks, smoking, flames and heat must be kept well away from the recharging site. The combustible hydrogen can result in an explosion if ignited by heat or flame.
If it touches the bare skin, sulfuric acid in the batteries can lead to chemical burns. This is not a problem during normal use of the battery, but if a battery is damaged or punctured, the acid could spray or leak, potentially burning anybody who is nearby.
Disposal
Disposing of lead-acid batteries improperly should be avoided at all costs. The sulfuric acid can either be recycled or neutralized or could be reused in new batteries. To be able to prevent the serious environmental consequences of incorrect disposal, all lead-acid batteries sold or purchased in the U.S. include a "core charge" that would only be returned if the used battery is turned in.
