Common emergency rescue knowledge (2)

Emergency response at construction sites is a critical aspect of safety management. It includes understanding basic first aid, trauma care, poisoning and heat stroke prevention, and infectious disease control. Mastering these skills can significantly reduce the risk of injury and improve survival chances during emergencies.

First, it's important to understand fire safety. A fire requires three elements: fuel, oxygen, and an ignition source. Effective fire response involves quickly identifying the threat and taking immediate action to suppress the flames before they spread.

Key steps in fire first aid include having a trained emergency team on site, evacuating non-essential personnel, and using appropriate firefighting equipment. Firefighters should act swiftly to contain the fire, prevent its spread, and ensure the safety of trapped individuals.

Proper use of fire extinguishers is essential. Different types are suitable for different situations—water for general fires, foam for wood and paper, CO2 for electrical and sensitive equipment, and dry powder for flammable liquids and electrical fires. Always follow manufacturer instructions to avoid further danger.

In case of smoke, people should stay low, cover their mouths with wet towels, and signal for help if unable to escape. Evacuation of materials should be organized to prevent additional hazards and maintain clear pathways.

Poisoning incidents, such as food or gas poisoning, require immediate action. If someone shows symptoms like vomiting or dizziness, encourage them to drink water and seek medical help right away. For gas leaks, never enter the area without proper protection—wait for trained rescuers.

Heat stroke is another serious concern, especially in hot weather. Move the affected person to a cool place, apply cold compresses, and provide fluids if possible. In severe cases, professional medical assistance is crucial.

Infectious diseases can spread quickly on construction sites due to large groups of workers. Implementing strict hygiene protocols, isolating sick individuals, and ensuring timely medical treatment are key to preventing outbreaks. Regular health checks and staff education also play a vital role in maintaining a safe working environment.
