As a critical component of personal protective equipment, the safety helmet is manufactured according to national mandatory standards. Its service life begins from the date of production. Plastic safety helmets have a maximum usage period of three years, while fiberglass helmets should not be used for more than two and a half years. Once this period expires, the helmets must be sent to authorized testing departments for inspection using specialized helmet testing equipment. Only those that pass the test can continue to be used; otherwise, they must be discarded immediately to ensure user safety.
Experts in occupational safety emphasize that each helmet should undergo proper evaluation through certified testing devices. The condition of the helmet—whether it is still safe to use—is determined by the data obtained from these tests, which helps prevent unsafe usage. During the testing process, a record is created for each helmet, and a label is affixed to indicate its current status. Any helmet that fails the test must be destroyed and not reused under any circumstances. Safety should never be taken lightly, and the issue of overusing safety helmets should not be overlooked. Everyone, especially safety managers, needs to pay close attention to this matter.
In daily safety inspections, field inspectors often focus on whether workers are wearing their helmets and if they are worn correctly. However, fewer people pay attention to how long the helmets have been in use. Overuse of safety helmets is a serious problem because prolonged use causes the shell material to become brittle. This reduces key performance characteristics such as impact absorption (tested with an impact tester), puncture resistance (tested with a puncture tester), lateral rigidity (tested with a lateral rigidity tester), electrical insulation (tested with an electrical insulation tester), and flame resistance (tested with a flame retardant tester). As a result, the helmet may no longer provide the necessary protection to the wearer.
According to recent surveys, many employees are unaware that safety helmets have a limited shelf life. In order to continue using them, they need to send the helmets to professional testing agencies for quality assessment using appropriate testing equipment. It's not uncommon for some workers to use a helmet for five or even ten years. Additionally, due to cost-saving measures or lack of proper management, some organizations fail to follow the recommended rotation schedules or regular quality inspections for their protective gear, further increasing the risk of accidents.

Solar LED Street Light has become an increasingly popular way of providing energy-efficient lighting for public spaces and roads. As the name suggests, solar street lamps are powered by solar panels that collect energy from the sun during the day, which is then stored in rechargeable batteries. This energy is then used to power LED lights, which can provide bright and long-lasting lighting for up to 12 hours without any additional power source. With the inclusion of various features such as motion sensors, solar induction street lights and more, these solar powered street lights have proven to be an effective solution for reducing energy consumption and carbon footprint. Let us dive deeper into the discussion and learn more about the benefits of this amazing technology.
