Low-Voltage Electrician Safety Operating Procedures

1. Safety Preparation

  • Before performing any low-voltage electrical work, personnel must wear approved protective equipment, including insulating gloves, insulating boots, and insulating workwear.

  • Carefully inspect all tools and equipment for proper operation. Report any damage or malfunction immediately for repair or replacement.

  • Ensure adequate ventilation at the worksite. Avoid prolonged work in confined spaces to prevent fire hazards or poisoning due to oxygen deficiency.

2. Safety Principles for Operation

  • Always disconnect the power supply before starting any electrical work, and implement reliable lockout/tagout procedures to prevent accidental re-energization.

  • Thoroughly review work instructions and relevant safety regulations prior to operation, and be fully aware of the work process and safety precautions.

  • Only qualified personnel with appropriate electrical knowledge and skills are permitted to perform electrical work. Untrained or uncertified individuals are strictly prohibited.

  • Electrical maintenance must not be performed under unsafe conditions. In exceptional cases requiring live work, power must first be disconnected and necessary protective measures implemented.

3. Safety Measures During Operation

  • Always verify that equipment or circuits are de-energized before contact, using a voltage tester to confirm the absence of current.

  • Use insulated tools when working on cable connections, switch operations, or similar tasks to avoid direct contact with live parts.

  • Never place equipment or tools on energized lines to prevent electric shock accidents.

  • Electrical repair and maintenance must strictly follow established operating procedures. Do not arbitrarily replace or dismantle electrical components.

  • Insulated tools must be in good condition; do not use damaged or worn insulated tools.

4. Fire Prevention and Emergency Measures

  • Be aware of flammable materials in the work area. Isolate them or take preventive fire measures if present.

  • When using open flames or flame-producing equipment, establish a fire-resistant barrier and remain vigilant to prevent fires.

  • In case of fire, immediately cut off the power supply, alert others via the alarm system, and initiate firefighting procedures.

  • Each work area must have sufficient fire extinguishing equipment, which should be regularly inspected for effectiveness and readiness.

5. Accident Handling and Reporting

  • In the event of an electrical accident or abnormal situation, the operator must immediately stop work and take emergency actions to ensure personal safety.

  • Effectively isolate the accident site to prevent unauthorized access and avoid secondary incidents.

  • Accidents must be documented and reported according to regulations, with detailed descriptions of the incident's course and cause, followed by accountability assessment.

6. Regular Inspection and Maintenance

  • Conduct regular inspections and maintenance on equipment and wiring after low-voltage electrical work to ensure safe and normal operation.

  • Inspections should include checks on insulation performance, wire connections, grounding conditions, and other critical aspects.

7. Training and Education

  • Personnel engaged in low-voltage electrical work must receive regular safety training and education to enhance safety awareness and operational skills.

  • Training content should cover electrical safety standards, accident response, and emergency procedures, ensuring every worker fully understands and complies with these operating procedures.

The above constitutes the main content of low-voltage electrician safety operating procedures. All operators must strictly adhere to these rules to ensure their own safety and that of others. Through standardized operations and scientific safety measures, accidents can be effectively prevented, ensuring the smooth and safe execution of electrical work.
