Corrosion is one of the primary challenges faced by bridge infrastructure, particularly in regions subject to harsh weather conditions or exposure to de-icing salts. Traditional materials, especially steel, are highly susceptible to rust, leading to costly maintenance and repairs. FRP materials, however, exhibit outstanding resistance to corrosion and chemical attack. By utilizing FRP bridge deck panels, engineers can significantly extend the life of a bridge and reduce long-term maintenance costs. This characteristic is especially beneficial in coastal areas or locations where infrastructure is frequently exposed to de-icing salts.

There are several types of machine guards, each designed for specific types of machinery and processes. Fixed guards are permanent and provide a solid barrier against moving parts. Adjustable guards can be modified for different tasks and machinery setups. Interlocking guards are designed to be connected to the machine’s operation; they ensure that the machine cannot operate if the guard is not properly positioned. Moreover, electronic safety systems exist, which use sensors. These systems can detect the presence of a worker in a hazardous area and immediately shut down the machinery to prevent an accident.
