There are at least 1,000 different chemicals created every year, out of all the chemicals in existence, 60,000 alone were created in the United States and this Dependence on chemicals by industrial society creates many problems. According to the United States Environmental Protection Agency [US EPA], 35,000 types of existing chemicals are considered hazardous to human health and the environment (cited in Shah, 2000). Hazardous wastes are materials made of chemical components that can easily harm the environment, exposing humans and other living things to disease and even death if misused or managed (US EPA, 2011 ). Hazardous waste, which contains hazardous compositions, can exist in many different forms, such as liquids, solids, gases or slush. These hazardous wastes may also be unwanted or leftover from commercial products such as cleaning fluids or pesticides (Satarkar, 2008). In order to avoid disastrous impacts on the environment, it is necessary to manage and control them properly (EnviroServ Waste Management, nd). There are different ways of managing, storing, treating, disposing of and controlling hazardous waste. To manage hazardous waste, you must first learn to identify waste, know its categories and the hierarchy of hazardous waste. A material is considered a hazardous waste when it has been classified either as a mixture of hazardous waste and non-hazardous solid waste, or as a mixture of characteristic hazardous waste and special nuclear materials, or as a leftover processing, storage, disposal waste or as the United States EPA had declared the product as such (Shah, 2000). There are four categories of hazardous wastes, namely characteristic wastes, listed wastes, general wastes and mixed wastes (US EP...... middle of paper ......R. (1989).
