Laboratory Coat Types and Fit

Lab Coat Selection and Fit Matter

Choosing the correct lab coat and ensuring proper fit is critical for protecting against specific laboratory hazards. A well‑selected, properly fitting lab coat reduces exposure, prevents skin contact, and allows safe, unrestricted movement during lab work.

Lab Coat Types

Different lab coats mitigate different hazards; no single lab coat provides full protection, and additional PPE, such as an apron, may be required depending on the task.

Material	99% Polyester blend
Uses	Fluid Barrier - sleeves are cuff Does not permit blood or other fluids to pass through For use with: Human blood, bodily fluids, tissues, or cells Other potentially infectious materials which contain bloodborne pathogens
Caution	Material is highly flammable, melts, and provides a fuel source once ignited.

Material	Nomex or Nomex like
Uses	Flame resistant material Resistant to many solvents and corrosives For use with: water reactive or air-reactive chemicals large volumes of flammables solvents potentially explosive chemicals open flames or potential for fire
Caution	Loose weave material provides superficial fluid barrier. Not for use solely with large volumes of corrosives

Material	Cotton and Polyester Blend
Uses	General Purpose use Protects skin and clothing from dirt, dye, low-hazard chemicals and biohazards, and radioactive material. For use in chemistry labs with low flammable solvent use.
Caution	Not for use with large volume of flammable pyrophoric or physical hazards that pose a risk of fire such as arc welding.

Coverage: The lab coat should fully cover your torso, arms, and upper legs, reaching at least to the knees (or mid‑thigh if approved for your lab).
Sleeves: Sleeves should extend to the wrist and fully overlap with gloves so no skin is exposed when arms are extended.
Closure: The lab coat must button or snap completely closed without pulling, gaping, or restricting movement.
Fit: It should be loose enough to allow comfortable movement and layering, but not so oversized that sleeves, fabric, or ties create a snag or spill hazard.
Length and movement: You should be able to bend, reach, and sit comfortably while maintaining full coverage.
Proper size: Select a size that fits your body and does not expose skin at the sides, chest, or arms during normal lab activities.
