PPE Coverall Testing

PPEs Coveralls are used as a barrier against infectious contaminated objects. They serve as an effective filter for infectious contaminants and as a crucial barrier to prevent cross-contamination from infections and human fluids such as blood, perspiration, saliva, vomit, semen, feces, urine, and skin cells.

Transmission of microorganisms through PPEs depends on:

Pore size (filtering capacity), thickness, and repellency of PPE
Morphology, size, shape, and environmental adaptation
Surface tension, volume, viscosity, and applied force
Physical, thermal, chemical, and environmental stresses
Type of carriers (body fluids, sloughed skin cells, dust, droplets, aerosols)

WRA has created following services for meeting the current requirement of PPE items testing.
