What is the best type of lab coat for working with chemicals?

Lab coats are a critical component of personal protective equipment (PPE) for individuals working with chemicals. They play a crucial role in safeguarding the wearer against splashes, spills, and other potential contact with hazardous substances.

When selecting a lab coat for chemical work, several critical factors should be taken into account:


Lab coats are commonly crafted from cotton, polyester, or a blend of both materials. Cotton, being a natural fiber, offers excellent breathability and comfort. However, it is not as chemically resistant as polyester. On the other hand, polyester, a synthetic fiber, provides superior durability and chemical resistance but lacks breathability.

For general chemical work, a lab coat made from a cotton/polyester blend is a suitable choice. It offers good protection against most chemicals while ensuring comfort during wear. Nevertheless, when handling highly corrosive or hazardous chemicals, a lab coat made from 100% polyester or a specialized chemical-resistant material becomes indispensable.


A lab coat should fit snugly yet comfortably, with sufficient length to cover the wearer's arms and torso, and sleeves long enough to extend over the wrists. Additionally, it is important for the coat to be fully closed at the front up to the collar.

Ensuring a proper fit is crucial as a loose coat can compromise protection against chemical splashes or spills on the skin, whereas a tight coat may cause discomfort and hinder movement.


Certain lab coats are equipped with supplementary features that offer added protection, including:

Pockets: Pockets serve as convenient storage spaces for pens, pencils, and other small items. Nevertheless, it is crucial to acknowledge that pockets can also act as reservoirs for chemicals. Therefore, it is imperative to evacuate and diligently cleanse them after each use.

Zippers or snaps: Zippers and snaps play a crucial role in securely closing the lab coat, effectively preventing any infiltration of chemicals.

Hoods: Hoods can offer supplementary protection for the head and neck, primarily when there is a potential hazard of chemicals splashing or spilling onto the wearer.

Choosing the right lab coat for your specific needs

The optimal lab coat for your needs will be determined by the specific chemicals and associated risks. If you are uncertain about the appropriate selection, consulting your safety officer is recommended.

Below are several specific recommendations for lab coats suitable for working with different types of chemicals:

General chemistry work: A lab coat crafted from a cotton/polyester blend is a recommended choice for performing general chemistry tasks.

Work with highly corrosive or hazardous chemicals: For tasks involving highly corrosive or hazardous chemicals, it may be imperative to wear a lab coat crafted from 100% polyester or a specialized chemical-resistant material.

Work with flammable liquids or open flames: A flame-resistant lab coat is required for work with flammable liquids or open flames. Flame-resistant lab coats are typically made from aramid fibers, such as Nomex.

Work with biological materials: For handling biological materials, it is advisable to utilize a lab coat crafted from a liquid-resistant material, like polyester or Tyvek.

Caring for your lab coat

Lab coats should be regularly laundered, particularly if they have been exposed to chemicals. It is crucial to meticulously follow the manufacturer's care instructions.

Here are some general tips for caring for your lab coat:

  • To prevent cross-contamination, it is advisable to wash your lab coat separately from other clothing.
  • Use a mild detergent and wash your lab coat on the coldest cycle possible.
  • Do not use bleach or fabric softeners, as these can damage the fabric and reduce the coat's protective properties.
  • Dry your lab coat on a low heat setting or hang it to dry.


Selecting the appropriate lab coat is crucial for safeguarding oneself against potential hazards associated with chemical work. When choosing a lab coat, take into account the nature of the chemicals used, associated risks, and personal preferences regarding features.

Furthermore, it is important to regularly launder your lab coat and adhere to the care instructions provided by the manufacturer. These practices not only help keep the lab coat in optimal condition but also prolong its lifespan.
