Final answer:
Plastic pipes, tubing, and fittings used to supply gas must adhere to specific regulations by the United States Department of Transportation and the EPA's hazardous waste regulations. These standards are crucial for safety and environmental protection. Knowledge of gas laws, which are taught in grade 11, is also important in understanding and applying these regulations.
Step-by-step explanation:
Plastic pipe, tubing, and fittings used to supply fuel gas must conform to United States Department of Transportation hazardous materials regulations, as well as EPA's hazardous waste regulations, and must be used in accordance with their specifications. These regulations ensure that the materials used are safe for transporting fuel gas and that they do not pose a hazard to public health or the environment. It is important that these guidelines are followed to prevent incidents such as leaks or explosions that could cause harm.
Additionally, these materials are part of a broader category of plastic products that include water pipes, Gas & Fire Pipelines, Electrical & Communications conduit, and various household items made of plastic such as hula hoop rings, five gallon buckets, and bottles for milk, juice, and water. The manufacturing and disposal of these products also fall under strict regulations to ensure that chemical wastes are managed properly. For instance, the chemical in the waste must be unused and in the form of a commercial chemical product to comply with waste disposal regulations.
Moreover, students studying these concepts in grade 11 will learn more about gas laws that apply to any gas at standard temperature and pressure, further highlighting the importance of understanding the properties of gases when designing and using gas supply systems. The extensive use of plastic for various applications underscores the need for proper regulatory compliance to maintain safety and environmental protection.
