The solvents may be flammable or toxic, and <br />paints may contain heavy metal pigments as well as hazardous solvents. <br /> <br />Graphic arts production may generate several types of wastes, <br />depending on the activities. Printing wastes include strong acid <br />solutions used to clean, etch, and coat plates, and solvents used to <br />clean plates, to apply light-sensitive coatings, and to develop <br />plates. The use of inks generates wastes containing solvents and/or <br />heavy metals. Photographic wastes include processing solutions, <br />developers, hardeners, and fixing baths. <br /> <br />Metalworlcing and automotive repair generate waste solvents <br />acid or alkaline solutions used to clean metal and remove rust. <br /> <br />and <br /> <br />Table 1 lists some typical shop operations and processes that may <br />produce hazardous waste. <br /> <br />If you produce between 220 and 2,200 pounds of hazardous waste <br />per calendar month, you are subject to small quantity generator <br />provisiions requiring the use of a Uniform Hazardous Waste Manifest <br />when you ship hazardous waste off your premises. <br /> <br />-48- <br />
