      Highlights

      • Leakage through the glove-protective clothing interface is critical in healthcare.
      • There is no test method available to quantify the leakage at the interfaces.
      • This study quantifies the fluid leakage at the coverall and glove interface.
      • A robotic arm was used to simulate upper extremity movements of healthcare workers.
      • Significant difference in fluid leakage amounts was found.

      Abstract

      Background

      Fluid leakage through the glove-protective clothing interface is an area of concern for many healthcare personnel, including emergency medical service providers, who may wear coveralls to protect themselves from multiple types of hazards. There is currently no established standard test method to specifically evaluate the barrier performance of the glove-protective clothing interface region for any personal protective equipment ensemble.

      Objective

      This study quantifies the fluid leakage at the coverall and glove interface using single and double gloving.

      Methods

      A robotic arm, which can simulate upper extremity movements of healthcare personnel, was used to test five coverall models and an extended examination glove model in single and double glove conditions.

      Results

      The results show that there was a significant difference in fluid leakage amounts between some of the coverall models and the number of glove layers studied. Findings also highlight that there is a high correlation between basis weight and stiffness of the coverall fabrics and the fluid leakage amounts.

      Conclusions

      These results underline that coverall constructed from thin and less stiff fabrics can result in lower fluid leakage levels. Also, there was no significant difference in fluid leakage amounts between single and double gloves when tested with each of the coverall models, with the exception of the coveralls with the highest basis weight and stiffness.
