First, the Purpose
To enhance the operators' ability to handle emergency situations in power distribution cabinets, reduce casualties and property damage caused by accidents, and improve the overall working environment, specific emergency response measures have been developed.
Second, Scope of Application
This plan applies to production workshops, work sites, and any area where electrical equipment is used or maintained.
Third, Identification and Analysis of Hazards
The company has ten low-voltage power distribution cabinets operating at 380 volts. These systems include dozens of cable connectors and various electrical components. During operation, these devices are prone to electric shocks, electrical fires, and even explosions due to faults or improper handling.
Fourth, Accident Modes and Consequences
(1) When a high-voltage system fails or is affected by lightning or other causes, it may lead to overvoltage, resulting in a power outage.
(2) Faults in primary equipment such as voltage transformers, current transformers, transformers, air switches, and cables—due to long-term overload, short-circuit failures, or poor contact at connection points—can cause insulation aging, overheating, and ultimately lead to electrical fires or explosions of voltage arresters and capacitors.
(3) If the secondary grounding of the high-voltage system is not properly maintained, high voltage can be induced in secondary equipment, posing a serious risk to personnel safety and causing electric shocks.
Fifth, On-Site Emergency Measures
If the power distribution cabinet shows abnormalities such as out-of-phase ammeters or broken fuses, the power should be disconnected immediately. The maintenance department or an electrician must be notified promptly. Power should only be restored after the issue is resolved.
Sixth, Alarms and Notifications
As soon as an electrical fire or electric shock occurs, call 119 for fire services or report to the relevant supervisor. In case of injuries, dial 122 to contact the emergency center immediately.
Seventh, Emergency Handling and Rescue Measures
(1) In the event of an electrical fire, quickly cut off the power supply and use a dry powder extinguisher to put out the fire. Immediately call 119 and notify the Safety Department or relevant leaders.
(2) If someone is electrocuted, disconnect the power source of the equipment immediately to free the person from the electricity. Provide on-site first aid, including artificial respiration if necessary. Upon receiving the report, the Safety Department and relevant leaders should organize a vehicle to transport the injured to the nearest hospital for prompt medical attention.
Eighth, Protective and Rescue Equipment
The production workshop should be equipped with qualified fire extinguishers, special firefighting tools like axes, buckets, and fire rafts. The company must also ensure that there are emergency vehicles available for quick response during critical incidents.
Ninth, Additional Notes
All employees should receive regular training on electrical safety and emergency procedures. It is crucial to maintain clear communication channels and ensure that all staff are aware of the emergency protocols. Regular inspections and maintenance of electrical systems should be conducted to prevent potential hazards before they occur.
Tenth, Conclusion
By implementing this comprehensive emergency response plan, the company aims to create a safer working environment, minimize risks, and protect both people and property. Continuous improvement and staff awareness are key to ensuring the effectiveness of the plan in real-life scenarios.
