  • Guide for Identifying Mercury Switches/Thermostats in Common Appliances
    Guide for Identifying Mercury Switches/Thermostats in Common Appliances Prepared by: Jim Giordani, Burlington Board of Health, Revised 12/27/00 Contact Todd Dresser for Further information at (781) 270-1956 - 1 - Guide for Identifying Mercury Switches/Thermostats In Common Appliances This reference contains guidance for responding to a mercury spill, and how to recycle mercury bearing products. This document also contains specific recommendations for the following types of products: batteries, fluorescent lights, high intensity discharge lamps (HID) lamps, ballasts, thermostats, switches, float switches, sump pumps, silent light switches, washing machines, tilt switches, freezers, flow meters, manometers, barometers, vacuum gauges, flame sensors on gas appliances, rubber flooring containing mercury, and mercury accumulation in sanitary drains. This reference also contains a general checklist of products found to routinely contain mercury. Mercury is a dangerous element in the environment today. It can cause serious health problems such as neurological and kidney damage. Mercury is found in many products that end up in landfills and incinerators allowing the mercury to re-enter the environment and pollute drinking water and contaminate the food chain. The following information is a helpful guide to identify products that contain mercury switches and thermostats. This guide describes where mercury switches and thermostats are located and how to remove and dispose of these properly. Mercury bearing articles should not be thrown in the trash, and serious care should be taken when dealing with this element. Safe Disposal · Store mercury thermostats and switches in a suitable sturdy, sealed container. A five gallon plastic bucket with a lid may work. · Each container must be labeled "Mercury Thermostats or Switches/Universal Waste." · Be careful to keep the devices from breaking and releasing mercury into the environment.

  • Five Signs That It Is Time to Replace the Mercury Based Relays and Switches in Your Industrial Application
    • white paper • white paper • white paper • white paper • industry: industrial process heating author: brian bettini Five Signs That it is Time to Replace the Mercury Based Relays and Switches in Your Industrial Application And What to Look for in a Suitable Replacement Summary: Mercury relays have been used in industrial applications for decades, most commonly for power switching. For example, in applications that use process heating, mercury relays are traditionally used to power on and off of electric heaters efficiently. But these kinds of relays are being replaced for several reasons. The latest generation of mercury relay/mercury switch alternatives is safer and more accurate and just as durable. • white paper • white paper • The background: mercury in industry U.S. patents for a mercury-based relay can be found as far back as 1937, and they have been used in industry for decades.1 They were first developed for applications where contact erosion could present a challenge for more conventional relay contacts, or where constant cycling was needed (such as heating operations). Mercury relays have been known to overheat, however, and there have been known cases of relays exploding and sending vaporized mercury into the workspace. This can potentially create a serious environmental and safety issue, not to mention the need for costly clean-up. But even with that risk, and with the EPA and the European Union placing bans on the use of mercury, some manufacturers are still using mercury relays or similar outdated switching devices. Why? Some industrial engineers claim to prefer mercury relays because they believe them to be durable and capable of handling difficult and dirty environments.

INTRODUCTION The material presented in this module is intended to provide you with an understanding of the fundamentals of electricity as applied to major appliances. Major appliances have become more sophisticated, taking them out of the screwdriver and pliers category. Their electrical circuits include several different types of automatic controls, switches, heaters, valves, etc.. Semiconductors, solid-state controls, and other components usually associated with radio and television electronic circuits, are being engineered into automatic washers, dryers, dishwashers, and refrigerators. The appliance technician is emerging into a professional status of his own. He must prepare himself now to be able to perform his duties today as well as to retain his professionalism in the future. No longer is on-the-job training sufficient to prepare technicians for the complicated procedures required for todays sophisticated appliances. This training can best be obtained through organized classroom study and application.

  • Removal of Vehicle Mercury Switch Assemblies
    Fact Sheet: Removal of Vehicle Mercury Switch Assemblies Hazardous Waste and Toxics Reduction Program Remove all mercury switch assemblies from vehicles as soon as possible after they enter the facility. Removal of mercury switches is quick and easy. Auto recyclers throughout Washington state report it takes approximately 30–60 seconds to remove the entire mercury light switch assembly. ABS G-Force Sensors take 5–7 minutes. Tools found most useful in doing the job include wire cutters, screwdriver, ratchet, wrench, pry bar, and pliers. Mercury Convenience Light Switches Any vehicle equipped with a convenience light in the hood and/or trunk is likely to have mercury switches if it’s a 2002 or older Ford or GM, or a 1998 or older Chrysler. Removing mercury hood and trunk convenience lights 1. Lift the hood or trunk and locate the small mercury lighting switch assembly. Refer to the Auto Mercury Switch Removal poster1 that lists the make/model, year, and location of switch, (e.g., hood or trunk). 2. Disconnect the battery. 3. Find the small light fixture on the underside of the hood or trunk. 4. Cut the wires leading to the device. 5. Remove the light assembly from vehicle. Unscrew, unbolt, or pry the light fixture from the hood/trunk. 6. Place light assembly in labeled container. You may remove as much of the device as possible to make more room in the container. Figure 1. Removal of hood and trunk convenience light switches Please note: In some instances (such as many GM vehicles), leaving the assembly intact and removing the pellet may be easier than removing the entire assembly.

  • An Access-Dictionary of Internationalist High Tech Latinate English
    An Access-Dictionary of Internationalist High Tech Latinate English Excerpted from Word Power, Public Speaking Confidence, and Dictionary-Based Learning, Copyright © 2007 by Robert Oliphant, columnist, Education News Author of The Latin-Old English Glossary in British Museum MS 3376 (Mouton, 1966) and A Piano for Mrs. Cimino (Prentice Hall, 1980) INTRODUCTION Strictly speaking, this is simply a list of technical terms: 30,680 of them presented in an alphabetical sequence of 52 professional subject fields ranging from Aeronautics to Zoology. Practically considered, though, every item on the list can be quickly accessed in the Random House Webster’s Unabridged Dictionary (RHU), updated second edition of 2007, or in its CD – ROM WordGenius® version. So what’s here is actually an in-depth learning tool for mastering the basic vocabularies of what today can fairly be called American-Pronunciation Internationalist High Tech Latinate English. Dictionary authority. This list, by virtue of its dictionary link, has far more authority than a conventional professional-subject glossary, even the one offered online by the University of Maryland Medical Center. American dictionaries, after all, have always assigned their technical terms to professional experts in specific fields, identified those experts in print, and in effect held them responsible for the accuracy and comprehensiveness of each entry. Even more important, the entries themselves offer learners a complete sketch of each target word (headword). Memorization. For professionals, memorization is a basic career requirement. Any physician will tell you how much of it is called for in medical school and how hard it is, thanks to thousands of strange, exotic shapes like <myocardium> that have to be taken apart in the mind and reassembled like pieces of an unpronounceable jigsaw puzzle.
