Engineering controls for electrical hazards include:

• Keyed access control systems to prevent unauthorized access to high voltage systems.
  
• Circuit-protection devices, which stop current flow when conditions become unsafe.
  
• Insulated tools for work near exposed electrical conductors.
  
• Insulation materials that stop or reduce the flow of electrical current.
  
• Equipment designs that use grounding conductors to direct unsafe current to the ground.

TA-53 has the largest number of high-power equipment with high voltage and/or high current at LANL. TA-53 is the single largest user of electrical power in Northern New Mexico during beam operation.
