Some of our power tools include lithium batteries. Lithium batteries are classified as "Dangerous Goods" under IATA DG Regulations, since charged battery shipments may overheat and ignite under certain conditions. Therefore at Mister Worker we implement measures so your shipments containing lithium batteries are correctly handled from when they are tendered to the courier at the origin to when they are delivered to their final destination. When shipped, lithium batteries are correctly identified and classified, as well as packaged and labeled accordingly.
