Electrostatic charges (ESC), generated from friction ofsurgeon scrub suitand disposable covers of polyester, have negative effect in health of the wearer. ESC building up on human skin are very harmful and can create serious health problems. Besides, the electric field generated from ESC can influence the efficiency of the electric appliances used in hospitals. The present study investigates ESC generated from the contact and separation as well as sliding of thesurgeon Scrub Suit and disposable covers of patients and people who are working in hospitals. Friction coefficientdisplayed by sliding ofsurgeon scrub suitagainst surgical disposable and patient covers decreased with increasing normal load. It is necessary that friction coefficient should have reasonable values so that the disposable cover should adhere well to the surgeon scrub suit to decrease friction between them that is responsible for generating ESC.Surgeon scrub suit as cotton generated positive ESC, while surgical and patient covers showed negative values. As the load increased, ESC increased due to the increased contact area, where the charge transfer became easier. Based on the relatively high values of ESC generated on the tested materials, it is necessary to propose suchmaterials of relatively low ability to generate ESC to decrease the danger of exposure of the patient and hospital team workers to electric field generated from ESC.
