Final answer:
Chemical-resistant gloves are the most important safety equipment when working with a strong base.
Step-by-step explanation:
The piece of safety equipment that is most important to have on hand when working with a strong base is the chemical-resistant gloves. These gloves protect the hands from direct contact with the base, which can be corrosive and harmful. They provide a barrier between the skin and the chemical, reducing the risk of burns or irritation.
While other safety equipment such as a fume hood, fire extinguisher, and eyewash station are also important, chemical-resistant gloves specifically address the need to protect the hands from direct contact with the base.
