Abstract

A fuel dispensing nozzle includes a body, a handle connected to the body, a handle guard connected to the body and generally surrounding the handle, and a spout extending from the body. Parts of the nozzle are made of, or covered in, static dissipative materials. Additionally, a method for reducing static discharge in existing nozzle installations includes the application of static dissipative material to existing nozzles to address certain static discharge risks.

         9 . The fuel dispensing device of  claim 1  wherein the handle is covered with a sleeve of static dissipative material.  
     
     
         10 . The fuel dispensing device of  claim 1  further comprising a handle guard, wherein the handle guard is electrically insulated from the body and handle.  
     
     
         11 . The fuel dispensing device of  claim 1 , wherein the nozzle is adapted to transfer fuel from a fuel transport vehicle to a tank.  
     
     
         12 . The fuel dispensing device of  claim 1 , wherein the nozzle is adapted to transfer non-flammable material into a flammable environment.  
     
     
         13 . A fuel dispensing system comprising: 
 a fuel dispenser;    a fuel dispensing nozzle;    a hose connecting the fuel dispenser to the fuel dispensing nozzle;    wherein the fuel dispensing nozzle comprises: 
 a body, a handle, and a spout,  
   wherein at least one of the body, handle, and spout comprises a static dissipative material.    
     
     
         14 . The fuel dispensing system of  claim 13  further comprising a vapor recovery system in fluid communication with the fuel dispensing nozzle.  
     
     
         15 . The fuel dispensing system of  claim 14  wherein the body of the fuel dispensing nozzle comprises a static dissipative material.  
     
     
         16 . The fuel dispensing system of  claim 14  wherein the fuel dispensing nozzle further comprises a handle guard and the handle guard comprises a static dissipative material.  
     
     
         17 . The fuel dispensing system of  claim 16  wherein the handle guard is electrically insulated from the body and handle.  
     
     
         18 . The fuel dispensing system of  claim 14  wherein the spout comprises a static dissipative material.  
     
     
         19 . The fuel dispensing system of  claim 14  wherein the spout comprises a structural material and an exterior coating comprising a static dissipative material.  
     
     
         20 . The fuel dispensing system of  claim 14  wherein the spout comprises a structural material and a sleeve comprising static dissipative material.  
     
     
         21 . The fuel dispensing system of  claim 13 , wherein the device is adapted to transfer fuel from a fuel transport vehicle to a tank.  
     
     
         22 . The fuel dispensing system of  claim 13 , wherein the device is adapted to transfer non-flammable material into a flammable environment.  
     
     
         23 . A method for reducing static discharge at existing nozzle installations, the method comprising the steps of: 
 locating an existing nozzle comprising a body, handle, and spout;    identifying a static discharge risk to be addressed; and    applying static dissipative materials to at least a portion of the existing nozzle to reduce the identified static discharge risk.    
     
     
         24 . The method of  claim 23  wherein:
