PPE Coverall Testing

PPEs Coveralls are used as barrier against infectious contaminated objects

  • Effective filter for the infectious contaminated objects
  • Barrier to stop cross contamination spread through various infections such as nosocomial infections, human fluid contaminants such as blood, perspiration, saliva, omit, semen, feces, urine and skin cells
  • Transmission of microorganisms through PPEs depends upon various factors such as
    1. Pore size (filtering capacity), Thickness, Repellency of PPE
    2. Morphology, size, shape and, adaptation of environment
    3. Surface tension, volume, viscosity and force
    4. Physical, thermal, chemical and environmental stresses
    5. Type of carriers (body fluids, sloughed skin cells, lint, dust, respiratory droplets and aerosolized molecules
