Safety features on a safety can?

Safety cans are designed with several key features to prevent accidents and ensure safe handling of flammable liquids. They typically include a self-closing lid that prevents spillage and minimizes vapors, a flame arrestor to prevent flames from entering the can, and a spout that allows for controlled pouring. Many safety cans also have a pressure relief valve to release excess pressure and a durable construction to withstand impacts. These features work together to enhance safety during storage and transfer of hazardous materials.
