  • 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.

  • Sensors and Switches in Industrial Air Compressors
    BACKGROUND Figure 1. Industrial Air Compressors Air compressors provide pressurized air to a variety of machine and other tools. They are often used in manufacturing, construction, chemical production, pneumatic power tools, oil and gas, food and beverage, and medical equipment applications. At a very basic level, an air compressor processes air from the outside to supply the tank(s) with air. Once the compressed air reaches a certain pressure point, the air compressor turns itself off. (See Figure 1.) SOLUTIONS Honeywell manufactures many electronic sensors and switches that may be used in industrial air compressors. They are designed to deliver system control, fluid level indication, temperature regulation, along with protection from overheating and starting/stopping the compressor. (See Figure 2.) Figure 2.
