People who work in places such as chemical laboratories, processing plants, medical diagnostic labs, and doctors who examine patients, etc. usually wear lab coats as a part of their work wear and also as protective apparel. These coats are worn as outerwear over their regular work clothes. In many other types of industries lab coats may form the uniform for people who work in the quality control department.
Most lab coats are made out of pre-shrunk cotton or blends of cotton and polyester. They are available in waist length and knee length versions and are generally designed for use in the industrial and medical sectors. Lab coats generally come with front knot buttons, one or two chest pockets with a built-in penholder and one or two lower waist area front pockets. Side slits are provided in the coats to allow unrestricted movement and to access the side pockets of your work pants. A back vent and a belt with knot buttons are usually provided.
The predominant color for lab coats is white, but the coats are also available in other shades and colors. Most industrial workers will wear colored lab coats, while medical and scientific workers will often wear white to signify cleanliness. Lab coats can also serve a function as they are designed to protect people and their work wear from hazards such as liquid spills and splashes Lab coats can be ordered in bulk an as singles and are available in different chest sizes for men and women.
Make sure that your lab coat fits you well and isn't too tight. It shouldn't hinder your arm movement while you are working. If you are wearing a loose fitting or knee length style of lab coat you should be careful when you are around machinery as it could get caught in a moving part. Most people who wear lab coats are professionals so they should try to keep their coats as clean as possible. It is also a good idea to have at least one extra lab coat available at work in case yours is damaged or stained while working.
