Older gas cooking equipment often contains mercury flame sensors or automatic gas-shut-off valves.
Gas-electric and electric ranges contain fluorescent bulbs for backlighting; gas-electric ranges may also contain a flame switch, which acts like a flame sensor. Commercial electric ranges may also contain relays. Chest freezers, washing machines, pool heaters, water heaters, irons and space heaters have all been found to contain mercury switches.
