Electrical isolation between objects is conducive to the build-up and potential discharge of static electrical charge. Isolated
ungrounded power systems, line isolation monitors (LIM), and ground-fault circuit interrupters
(GFCI) are further examples of technologies employed in operating rooms to
reduce the risk of explosion in the presence of combustible anesthetic agents. These technologies
also serve to reduce the risk of explosion from electrical shocks resulting from
stray (leakage) current.
