What safety precautions are necessary when working with nickel-cadmium batteries?

Several safety precautions are necessary when working with nickel-cadmium (NiCd) batteries due to the potential hazards associated with their chemical composition and electrical characteristics. Eye protection, such as safety glasses or a face shield, is essential to protect against splashes of electrolyte, which is corrosive. Hand protection, such as chemical-resistant gloves, is necessary to prevent skin contact with the electrolyte. Adequate ventilation is required to prevent the buildup of hydrogen gas, which can be released during charging and can be explosive. Do not smoke or use open flames near NiCd batteries. Proper tools, insulated for the voltage, should be used to prevent electrical shock. Avoid short-circuiting the batteries, as this can cause them to overheat and potentially explode. When lifting heavy batteries, use proper lifting techniques and equipment to avoid injury. Follow the battery manufacturer's instructions for charging and maintenance. Ensure that the charging equipment is properly calibrated and functioning correctly. Avoid overcharging or deep discharging the batteries, as this can damage them and reduce their lifespan. Properly dispose of used NiCd batteries according to local regulations, as they contain hazardous materials. In case of electrolyte spillage, neutralize it with a weak acid solution (such as vinegar) and clean the area thoroughly.
