Firemen wear hats made of fiberglass because fiberglass is lightweight, durable, and provides excellent insulation against heat. Unlike metal, which can become extremely hot and potentially cause burns, fiberglass retains its shape and protective qualities under high temperatures. Additionally, fiberglass helmets can be designed to include ventilation and impact resistance, enhancing safety and comfort for firefighters in challenging environments.

The first Robot was built by General Motors in USA. It was made to help in beating metel sheets. It looked nothing like a human- rather a giant cow!
Fibreglass water tanks are generally not recommended for diesel storage due to potential chemical compatibility issues. Diesel can degrade the resin used in fibreglass tanks, leading to leaks or contamination. For diesel storage, it's better to use tanks specifically designed for fuel, such as those made of steel or high-density polyethylene (HDPE), which are built to withstand the properties of diesel and prevent leaks. Always check local regulations and guidelines for fuel storage to ensure compliance.
