Hazardous Waste is any material that will cause harm to humankind. The waste material can be in the form of a solid or liquid or even a gaseous state. These material are not only harmful to human beings but they also harm the environment. The material maybe discarded cleaning chemicals or the waste from manufacturing processes.
Why do we call the waste as hazardous? This is because we cannot dispose of these wastes like how we dispose other harmless waste.
The Resource Conservation and Recovery Act (RCRA) regulates and directs the procedure to be followed with harmful waste. There are two types of waste according to RCRA. One is characteristic and other is listed. Characteristic wastes are wastes that are reactive, corrosive, ignitable, or toxic. If the source is specific, non-specific, or chemical waste that is thrown away then it is known as listed waste. PE Prep Course includes the concept of hazardous waste.

Hazardous content is ignitable if fire arises due to rubbing or any friction. Fire arises even when the waste comes in contact with water and absorbs moisture. A waste is corrosive if it has a PH that is less than or equal to 2 or a PH greater than or equal to 12.5. A waste is said to be reactive if it reacts violently with water or moisture. The waste is capable of detonation under certain forces. It is said to be toxic if it contains a carcinogen at a concentration greater than or equal to.001%. Treated wood leftover may also be toxic. Wood that has been given some chemical treatment to protect or save the wood maybe toxic. Examples of treated wood waste are landscape timbers, fence posts, railroad ties, decaking, and guardrails. The PE Exam Prep helps you to know the different types of hazardous waste.
Hazardous leftovers may be generated by different type of companies. Chemical factories, dry cleaning zones, hospitals, cosmetic making units, and oil refineries may produce toxic remains.
Hazardous waste is not only generated in factories, but it is also generated in homes. The harmful waste generated at home can be from paints, waste from automobiles, pesticides, switches, thermometers, and electronics items. Old batteries, refrigerant coolers, and home smoke detectors also leak and lead to bad waste.
Other examples of hazardous waste are telephones, answering machines, radios, video cassette players, calculators, CDs, and more. Sodium vapour lamps, fluorescent lights, and lamps containing mercury also lead to toxic waste. Mercury thermostats, mercury switches, aerosol cans, dental amalgam wastes, pressure or vacuum gauges containing mercury contain toxic remains. Garden chemicals such as, fertilizers, herbicides, insecticides, pesticides, and sharp things such as needles and lancets, and swimming pool chemicals can be toxic leftovers. The PE Exam introduces the different harmful waste.

There are several methods to dispose hazardous waste. Landfills are used to dispose leftovers. While using landfills, one should make sure that it is properly covered and there are no leaks. Adequate protection against storms must also be provided for the landfills.
Sunlight and soil microbes are used to treat hazardous leftovers in Land Treatment methods. Waste management practices of a particular area will be listed in the government websites. Some days maybe fixed on which garbage collection and disposal drives happen.
The National Council of Examiners for Engineering and Surveying (NCEES) conducts FE and PE exams for engineers. Hazardous waste is one of the topics for the exam. The Professional Engineer Exam Prep Course will coach you towards having a good knowledge of hazardous waste.
