Electric static charges generated from friction of engineering materials cause electromagnetic fields influencing their applications. The electromagnetic fields found in hospital operating rooms can be quite hostile to electronic medical devices. In the present work, the electric static charge generated from the dry and water wet contact and sliding of surgical gloves and the covers of the cloths of people who are working in hospitals is investigated. It was found that friction coefficient displayed by dry sliding of latex glove against cover decreased with decreasing normal load. Friction values guaranteed the good adhesion of the glove against cover. At sliding, the charge value was higher than that recorded for contact and and separation. At water wet contact, the values of friction and electric static charge were lower than that observed for dry contact due to the ability of water to conduct the charge from the contact surfaces. Based on the experimental observations, it can be concluded that materials of both glove and cover generated very high electric static charge values. It is therefore necessary to select the materials of low electric static charge.
