On construction sites, safety helmets, safety belts, and safety nets are essential protective gear that must be used to ensure the well-being of workers. While the use of these safety items has become more standardized in recent years, there are still instances where workers fail to follow safety protocols. In this article, we will explore the proper usage and importance of these three critical safety tools. Safety helmets are required for all workers entering high-risk areas on a construction site. These helmets must meet industry safety standards and should always be properly fastened to prevent them from falling off during work. A loose or improperly worn helmet can significantly reduce its protective effectiveness, putting workers at risk of head injuries. Safety belts are crucial for workers performing tasks at heights above 2 meters. They should be securely attached to a fixed structure, such as a safety railing or anchor point, to prevent falls. If the work area does not have an existing attachment point, appropriate measures must be taken to ensure the safety belt is properly secured before starting the task. Safety nets are another vital component of fall protection, especially in high-rise construction. A fixed safety net must be installed every four floors, and additional horizontal safety nets should be placed alongside the building walls. In areas without external protection, a safety net must be erected at least 4 meters above ground level to catch any potential falls. In addition to personal protective equipment, construction sites must also focus on the "four openings" – stairs, elevator shafts, reserved openings, and entrances (also known as "mouths"). These areas are particularly dangerous if left unprotected. To safeguard workers, fences, cover plates, metal doors, and nets should be installed around these openings. For prefabricated concrete openings, steel bars are often pre-embedded during manufacturing, and these are cut when the equipment is installed. For building entrances and other high-traffic areas, standard-compliant shelters must be erected to protect workers from falling debris and provide a safe entry and exit route. These measures are essential for maintaining a secure working environment and preventing accidents.
