Lab coats are not just a fashion statement or a symbol of professionalism, they are also an important form of personal protective equipment (PPE) that can protect us from various hazards in the lab. In this article, we will explore the function and benefits of lab coats, as well as some tips on how to choose and care for them.

Function and Benefits of Lab Coats

Lab coats provide protection of skin and clothing from incidental contact and small splashes of hazardous substances, chemicals, or biological agents present in the lab.
Lab coats prevent the spread of contamination outside the lab, provided they are not worn outside the lab.
Lab coats provide a removable barrier in the event of an incident involving a spill or splash of hazardous substances.
Lab coats can also protect us from radiant heat, sparks, and infrared or ultraviolet radiations.

How to Choose a Lab Coat

The type and material of lab coat should match the level of risk and the type of hazard in the lab. For example, a flame resistant lab coat is required when handling pyrophoric substances or flammable chemicals, while a lab coat without pockets and that buttons up to the neck is required when working with biological agents at BL2 or higher.
The size and fit of the lab coat should be comfortable and allow for freedom of movement. The sleeves should not be pulled up or rolled up, as this exposes the skin to potential hazards. The buttons should be done up when in the lab.
The color and design of the lab coat can be a matter of personal preference or departmental policy. Some labs may use different colors to indicate different roles or levels of training. Some labs may also allow customized or personalized lab coats, as long as they do not compromise safety or hygiene standards.

How to Care for a Lab Coat

Lab coats should be cleaned regularly to remove any dirt, stains, or contamination. The frequency and method of cleaning depend on the type and material of the lab coat, as well as the type and level of hazard in the lab. Some labs may provide laundry services for lab coats, while others may require users to wash their own lab coats following specific instructions.
Lab coats should be inspected before and after each use for any signs of damage, wear, or tear. Any lab coat that is torn, frayed, stained, or contaminated should be repaired or replaced as soon as possible.
Lab coats should be stored properly when not in use. They should be hung on hooks or hangers in designated areas within the lab or in lockers outside the lab. They should not be left on chairs, tables, benches, or floors in the lab, as this can cause cross-contamination or tripping hazards. They should also not be taken home or worn outside the lab, as this can spread contamination or expose others to potential hazards.

Conclusion

Lab coats are more than just a piece of clothing, they are a vital part of laboratory safety. By understanding their function and benefits, choosing the right type and material, and caring for them properly, we can ensure that we are protected from various hazards in the lab and that we maintain a high standard of hygiene and professionalism. Remember, wearing a lab coat is not only good for you, but also good for your colleagues and your environment.
