An umbilical connection for use in a hazardous environment like a floating roof storage tank has one or more hydraulic hoses, one or more electrical cables or a combination thereof Each hydraulic hose has a static dissipative and abrasion resistant covering. Each electrical cable has an abrasion resistant coating. The hoses and cables are bundled and wrapped in a static dissipative and abrasion resistant open mesh sheath or an overbraid to form the intrinsically safe umbilical connection.
