SaferProducts.gov consumer incident report 20190702-19BE6-2147380121. Severity: Injury, First Aid Received by Non-Medical Professional. Product: Krazy Gears 81 pcs playground edition (see above. KRAZY GEARS INTERLOCKING LEARNING BLOCKS 81 PCS, AGE 3). Incident: SHORT CIRCUIT, HEAT, AND BURN HAZARD FROM KRAZY GEARS. My 3 and 1 � yr old grandsons were playing with their KRAZY GEARS INTERLOCKING LEARNING BLOCKS, the Playground Edition , 81 pcs, ages 3. Manufactured for and Distributed by S. C. Chang, Inc, Ontario, California 91762. About 2 hrs ago my daughter heard a cry from the 1 � yr old and she ran over and grabbed the motorized gear piece and it was so hot she could barely grab it. As she carried it to the kitchen sink it gave out a pop and a little liquid from the ruptured battery got on her hand. She treated the burn to her hand with baking soda. The blessing is that it was only 30 sec after grabbing it from my grandson that it ruptured. Had she not been diligent it would have gotten my grandson. We have pictures of the device and the burned ends of the battery.We also have the device itself on a concrete floor in the garage. Obviously it developed a short, presumably in the tiny silver motor that drives the gear.
