Explanation:
Handling a Hot Beaker Safely
When you are heating a beaker and need to pick it up, the best choice would be to use tongs. This method provides a secure grip and minimizes the risk of burning your hands. It is critical to avoid using your hands directly, as touching a hot beaker can result in serious burns.
Other options, such as using a rag or paper towels, can be ineffective because they may not provide enough grip, particularly if they absorb heat. Picking up the beaker by the end away from the heat is not always safe, as it doesn’t guarantee that you won’t touch the hotter part of the beaker. Pouring cold water on the beaker is also highly discouraged, as it could cause thermal shock, potentially breaking the glass.
Always remember to handle hot glassware with care, using appropriate tools designed for heat resistance to ensure your safety in the laboratory.
