Universal Waste Categories <br /> Batteries (for more information see publication number 98-407.a) <br /> All batteries that are dangerous waste can be managed as UW including: <br /> ► Alkaline ► Button cell mercuric oxide <br /> ► Mercuric-oxide ► Silver oxide <br /> ► Alkaline-manganese ► Lithium <br /> ► Zinc-carbon ► Nickel-cadmium(Ni-Cd) <br /> ► Zinc air <br /> Spent lead-acid batteries (typically automotive type batteries) can also be managed as UW. <br /> However,they are most often managed under the optional lead-acid battery exemption at <br /> WAC 173-303-520. <br /> Mercury-containing equipment(MCE) (for more information see publication number 98-407.b) <br /> Mercury-containing equipment is defined as a device or part of a device that contains <br /> elemental mercury necessary for its operation. Thermostats fit the definition of mercury- <br /> containing equipment and are managed basically the same way;however,labeling and record <br /> keeping requirements are different. Some examples of MCE include: <br /> > Thermometers <br /> ➢ Barometers <br /> ➢ Manometers <br /> ➢ Relay and tilt switches <br /> ➢ Flame sensors <br /> Some examples of material that would not be MCE include: <br /> ➢ Containers of elementary mercury <br /> ➢ Dental amalgam <br /> > Chemical compounds containing mercury e.g.,pharmaceuticals,pesticides,paints or <br /> lab chemicals <br /> ➢ Devices which only contain mercury in removable lamps or batteries,e.g., flat screen <br /> monitors <br /> Mercury-containing thermostats (for more information see publication number 98-407.b) <br /> Mercury-containing thermostats can be managed as UW. A thermostat is a temperature <br /> control device containing mercury in an ampule. Ampules removed from these thermostats <br /> can also be managed under the UW requirements. These requirements provide performance <br /> standards for removal of ampules,such as use of a containment system(for example,a plastic <br /> tub under the work area) to prevent spills during removal. <br /> 2 <br />
