Safety gear required for work at height
Safety helmets, safety belts (or lanyards), and safety nets are collectively known as the "three essentials" in high-place operations, playing a vital role in protecting workers from potential injuries. These tools are essential for ensuring safety on construction sites, industrial environments, and other high-risk areas. 1. Safety Helmets A safety helmet is personal protective equipment designed to minimize head injuries caused by falling objects or side impacts. It typically consists of two main components: the shell and the liner. The shell is usually made of plastic, rubber, metal, or natural fibers, while the liner provides cushioning and comfort. According to the national standard GB 2811-1988, helmets must meet strict quality requirements. Before each use, always inspect the helmet for cracks, dents, abrasions, or any signs of damage. Ensure it is worn correctly, with the chin strap properly fastened. Avoid placing the helmet in direct sunlight, high temperatures, or acidic/alkaline environments. Never store it with sharp or hard objects, as this can compromise its integrity. If a helmet has experienced a significant impact, it should be immediately replaced and not reused. 2. Safety Belts (Lanyards) A safety belt is a critical piece of equipment that secures the worker to a fixed point, preventing falls and reducing the risk of severe injury. It generally includes a belt, rope, and metal components such as hooks and rings. The materials used are lightweight, durable, and resistant to wear, moisture, and temperature changes. Commonly used materials include cotton, vinylon, and silk for ropes, while metal parts are often made from carbon steel or aluminum alloy. Safety belts come in various types, including those for working around poles, suspended tasks, and climbing activities. They are also categorized based on the profession, such as for electricians, telecom workers, firefighters, and more. When selecting a safety belt, ensure it has proper certification and is suitable for the specific job. To use a safety belt correctly, always connect it to a secure anchor point. The principle of “high hanging, low use†should be followed. Before each use, perform a visual inspection to check for fraying, wear, or damage. Make sure all hooks, rings, and clips are securely fastened. After use, store the belt in a dry and safe place, away from moisture or heat. 3. Safety Nets Safety nets are designed to prevent people and objects from falling, as well as to reduce the impact of falling items. They are typically composed of a net body, side ropes, tether ropes, and other structural elements. There are two main types: flat nets, which are installed parallel to the ground, and vertical nets, which are installed perpendicular to the ground. When choosing and installing a safety net, it’s important to have trained personnel handle the process. After installation, the net must be inspected by a qualified safety officer before use. During operation, avoid dragging the net over rough surfaces, placing heavy objects inside or under the net, or allowing large debris or sparks to fall into it. Also, avoid using the net in areas with corrosive fumes or chemicals. It’s recommended to inspect safety nets at least once a week. If the net experiences a major impact, it should be checked or replaced immediately. Regular cleaning of the net is necessary to maintain its effectiveness. Always ensure that the test rope remains intact and functional. Every three months, a strength test should be conducted on the net. Never dismantle the net without proper authorization, and always store it under the supervision of designated personnel.
