Common emergency rescue knowledge (1)

Emergency response knowledge on construction sites is essential for ensuring the safety of workers. It includes basic emergency procedures, first aid techniques, trauma management, and handling of poisoning or heat-related incidents. Understanding these fundamentals is a critical part of maintaining a safe working environment.

First, understanding the basics of emergency rescue is crucial. Emergency personnel involved in major accidents must undergo proper training to ensure that rescues are carried out in an organized and effective manner. Blind actions without knowing the situation can worsen the outcome. The main tasks during an emergency include eliminating harmful effects, identifying the cause of the incident, rescuing victims, and controlling the situation while monitoring potential hazards.

Second, electric shock first aid is vital. In most cases, the survival of an electric shock victim depends on quick removal from the power source and timely implementation of artificial respiration and chest compressions. Delays or improper actions can lead to severe consequences.

Construction companies should establish comprehensive emergency response systems at both enterprise and project levels. These plans must be developed and regularly reviewed to ensure preparedness. When a general contractor is involved, the main accident plan should be followed, with each subcontractor also having its own emergency strategy.

When dealing with electric shocks, it's important to assess the condition of the victim. If conscious but weak, the person should rest and be monitored. If unconscious but breathing, they should be placed on their back and kept warm. In the case of no breathing or heartbeat, immediate CPR is necessary. For mouth-to-mouth resuscitation, the patient should lie flat, and the rescuer should blow air into the lungs at a rate of 12 breaths per minute. Chest compressions should be performed at 60 times per minute to maintain circulation.

To disconnect someone from an electric source, the power switch should be turned off if accessible. For high-voltage situations, notify the utility company immediately. Use insulated tools when handling electrical equipment, and avoid direct contact with live wires. Be cautious of secondary injuries such as falls or fractures after disconnection.

Trauma can be classified into open and closed wounds. Open wounds involve damage to the skin or mucous membranes, such as cuts, lacerations, or burns. Closed wounds affect internal tissues without visible skin damage, like bruises or contusions.

For open wounds, cleaning the area with saline or clean water is essential. Apply pressure to stop bleeding using gauze or cloth, and cover the wound to prevent infection. For burns, remove the burn source and protect the affected area with a clean dressing. Avoid breaking blisters unless under medical supervision.

Closed wounds require careful handling. Cold compresses can reduce swelling and bruising. If there's suspicion of internal injury, the victim should not be moved unnecessarily. Use a stretcher or support method to transport them safely. Ensure the airway remains open and watch for signs of shock. In emergencies, provide immediate CPR if needed.
