Final answer:
The tool designed to hold broken glass to avoid injury is beaker tongs, which are specifically made for safely handling glassware in a laboratory setting. So, the correct answer is option (d).
Explanation:
The correct answer to the question of which tool holds broken glass to avoid injury is Beaker tongs. Beaker tongs are specifically designed to hold and transport laboratory glassware, such as beakers, safely and securely. When dealing with potentially hazardous or sharp broken glass, using the proper equipment is essential to prevent injury.
In a laboratory setting, there are various tools and instruments at one's disposal, all with specific purposes. For example, crucible tongs are used for handling hot crucibles, test tube clamps hold test tubes when they are heated, and forceps could be used to pick up small objects. However, in the context of the question, which focuses on the avoidance of injury from broken glass, the most suitable and safe choice is beaker tongs.
Beaker tongs typically have coated jaws which provide a firm grip and protect the user from heat and breakage. Unlike a pipette bulb or a test tube clamp, beaker tongs have the size and shape designed to accommodate beakers, which means they can also be useful in handling other broken glassware in an emergency. Nonetheless, it is always recommended to clean up broken glass with a dustpan and broom and to wear protective equipment like gloves and goggles when handling broken or hazardous materials in a lab setting.
