federally listed halogenated hazardous wastes and thus would be managed as a <br />hazardous waste in California. The oil generated from two refrigerator recycling <br />operations in California has tested over 4000 mg/kg halogens. One recycler has taken <br />measures to reduce the halogen concentration for purposes of recycling the oil while the <br />other recycler sends the oil to a facility for use as a blended fuel3•20. <br />All generators (other than householders) and haulers of used oil must obtain an <br />Environmental Protection Agency (EPA) identification (ID) number. For further <br />information on how to obtain an EPA ID number, call DTSC at (916) 324-1781. Used <br />oil haulers can be found in the yellow pages under Oil -Waste or Waste. <br />For a further discussion on handling, storage, and transport of used oil, refer to the <br />Used Oil Fact Sheet in appendix C. <br />5.0 Mercury <br />Mercury, a silver -white metal which is a liquid at room temperature, has been used in <br />the past in consumer and industrial goods, such as thermometers, thermostats, <br />barometers, electrical switches, and batteries. Now, due to environmental concerns, <br />mercury is being phased out of batteries, and mercury temperature controls are being <br />replaced with electronic devices. Current uses of mercury include thermometers and <br />fluorescent lighting$. <br />5.1 Discards Containing Mercury <br />Small amounts of mercury may be found in switches used in some old washing machines <br />and chest type freezers and in temperature controls in gas stoves and water beaters'.. . <br />The switch on the chest type freezer will be located under the lid seal and is used to turn <br />on the interior light 14. The switch on the washing machine is located under the lid and <br />is used to stop the washing machine when the lid is opened during operations (see Figure <br />9). You can determine if the switch is liquid filled by shaking it. These switches will <br />either be encased in plastic or glass14. In a stove, the mercury switch is a long, thin <br />copper tube connecting the thermostat to the gas burner control$ (see Figure 10). <br />5.2 Mercury Component Removal Methods <br />Tools / Equipment Needed <br />The basic tools needed for removing the components containing mercury are; 1) <br />screwdriver, 2) nut driver set, 3) crescent wrench, 4) socket set, and 5) side cutters or <br />wire cutters. <br />18 <br />C7 <br />
