What is the primary purpose of a lab coat in a chemistry lab?

A lab coat is primarily designed to protect the wearer from potential hazards in a chemistry lab, particularly from chemical spills. It acts as a barrier between the skin and harmful substances, reducing the risk of skin exposure to corrosive materials or harmful chemicals. The fabric of the lab coat is typically made of materials that resist chemical penetration, thus serving as an essential piece of personal protective equipment.

While obscuring personal clothing and identifying personnel roles may be secondary benefits, they do not capture the primary function of a lab coat in a safety context. Additionally, keeping the wearer warm is not its main purpose, as lab environments can vary in temperature, and a lab coat is not designed specifically for insulation. The primary focus of wearing a lab coat is safety and protection from the various risks encountered in a chemistry laboratory.
