Five Prohibitions Regarding High-Voltage Distribution Boxes
High-voltage distribution boxes must never be tampered with, improperly maintained, or accessed without proper authorization and protective measures.1. Do Not Access Without Authorization or TrainingOnly qualified personnel with proper training and certification should operate or access high-voltage distribution boxes. Unauthorized access can result in severe electric shock, burns, or fatal injuries due to the high energy levels involved in these systems .2. Do Not Operate or Modify Equipment Without Proper TestingHigh-voltage circuits must be protected by circuit breakers or fuses of correct type and capacity. Any operation, repair, or modification must follow strict testing and examination procedures, including visual inspections and functional tests of protective devices .3. Do Not Ignore Grounding and Protective DevicesGrounding resistors and protective relays are critical for limiting fault currents and preventing overvoltage. Tampering with or bypassing these devices can lead to dangerous voltage spikes, equipment damage, or arc flashes .4. Do Not Work Without Personal Protective Equipment (PPE)Working near high-voltage distribution boxes requires insulated gloves, face shields, and other PPE. Failure to use proper protective equipment increases the risk of electric shock, arc flash injuries, and burns .5. Do Not Neglect Maintenance and Safety RecordsRegular maintenance, testing, and documentation of all high-voltage equipment are mandatory. Neglecting these procedures can result in undetected faults, equipment failure, and serious safety hazards . Following these prohibitions ensures compliance with safety regulations, minimizes the risk of electrical accidents, and protects both personnel and property in high-voltage environments.
