List four ways you can avoid injury while using HCl and three steps you would take in case of an accidental exposure to HCl.

Answer:

Avoid injury by wearing safety goggles or a face shield, gloves, and an apron or lab coat; using extra care when transferring HCl; working in a well-ventilated area; and never mixing HCl with other chemicals unless instructed. In case of exposure, rinse the affected skin with large amounts of water, rinse the eyes thoroughly at the eyewash station, and seek medical attention.
