Lab coats should cover the entire upper body, extend to the knees, and fit comfortably without hanging too loosely from the arms. Only single use disposable lab coats or lab coats that are routinely laundered by an approved vendor may be used.
Lab aprons are designed to be worn in combination with a lab coat to provide extra protection when pouring corrosive chemicals, using an acid bath, or manipulating chemicals in a manner that increases the likelihood for splashes or spills. Lab aprons should fit comfortably and extend from just below the neck to just above the tops of the feet.
