oAnyone working with chemicals Stop the Burn Remove the cause Refer to how to treat via chemical guide Remove clothes Shower oHousehold Electrical burns Electricity follows the path of least resistance Tends to lie among muscles, bone, blood vessels, and nerves Could take weeks after initial burn to tell the full extent of injury Entry and Exit wounds Tissue necrosis results from impaired blood flow secondary to blood coagulation at the site of an electrical injury May develop gangrene if necrosis is severe oAmputation is then needed The higher the voltage the more injury Alternating Current Produces repeated electrical surges that lead to tetanic muscle contractionsoInhibit respiratory efforts for the duration of the contact oMay result in respiratory distress oMay cause the individual to clamp down on the power source Increasing the duration of contact At Risk Occupation oElectrician Children Older adults Stop the Burn Use a nonconductive piece of equipment oWooden broomstick Stop the current Safety of the rescuer oHigh Voltage Electrical burns Electricity follows the path of least resistance Tends to lie among muscles, bone, blood vessels, and nerves Could take weeks after initial burn to tell the full extent of injury Entry and Exit wounds May not always be clear Tissue necrosis results from impaired blood flow secondary to blood coagulation at the site of an electrical injury May develop gangrene if necrosis is severe oAmputation is then needed
