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 and human fluid contaminants such as blood, perspiration, saliva, vomit, semen, feces, urine, and skin cells
- Transmission of microorganisms through PPEs depends upon various factors such as
- Pore size (filtering capacity), thickness, repellency of PPE
- Morphology, size, shape, and adaptation to environment
- Surface tension, volume, viscosity, and force
- Physical, thermal, chemical, and environmental stresses
- Type of carriers (body fluids, sloughed skin cells, lint, dust, respiratory droplets, and aerosolized molecules)
