If you move it or shake it, it can build up pressure and when you open the lid a bit of hot water could spray out. We recommend brewing tea in it and leaving it on a flat surface until such time as you open the lid and pour the tea. It is also recommended that you don't fill all the way to the top when adding hot water to it, leave an inch or more of space inside to prevent water from spraying out when you open it. When opening it, keep it at an arm's length and away from your face, pets, children, etc. Failure to properly screw on the top tightly enough could result in scalding water spraying or leaking out and causing burns. Failure to heed these directions, improper, or unintended use of this product may result in burns from scalding hot water. If the product is defective in any manner discontinue use immediately!
