  1. Carbon Monoxide Detectors By: Baltej Gill & NavSidhu

  2. What is Carbon Monoxide? • Colorless, odorless • Flammable, very poisonous • Highly toxic in high quantities • Formed when not enough Oxygen atoms in presence of appliance (stove, combustion engine) • One carbon atom + one oxygen atom • Triple bond, consisting of two covalent bonds and one dative bond

  3. What is it Used For? • The making of Chemicals • Aldehydes that can be used to make detergents • Methonal which can be used to make larger hydrocarbon molecules • Production of acetic acid

  4. Dangers of Carbon Monoxide • Particles bond with hemoglobin in your blood stream preventing oxygen from binding to it. • Only low concentrations are required to lock up hemoglobin, causing death through asphyxiation • Asphyxiation – condition of being deprived of oxygen • Hemoglobin – oxygen transport in red blood cells of all vertebrates, oxygen from lungs to body.

  5. Carbon Monoxide Detectors • Warns of high concentrations of this deadly gas • Every house with a wood burning stove, or gas/oil burning appliances should have carbon monoxide detectors • 3 types of CO detectors • Metal Oxide Semi Conductor, Biomimetic, Electrochemical

  6. Metal oxide semi conductor • Original technology of detecting CO • Heated tin oxide reacts with CO to determine the levels of toxic gas • No need to remember to check batteries, connected to house power

  7. Biomimetic • Gel coated disks that darken in presence of CO • Color change sounds an alarm • Less expensive, battery operated

  8. Electrochemical • Chemical reaction with CO creates electrical current that sets alarm • Highly sensitive and offor accurate readings • Comes with digital read out and memory to refer to passed CO levels • Sounds an alert when sensor needs to be replaced

  9. When Purchasing CO Detector Features to Consider: • Listed in Canadian Standards Association (CSA) • Chose a detector with a memory to check long term • Battery operated detectors allow for convenient placement, however require users diligence • Do not plug detector in outlet controlled by wall switch. • Replace at least every 5 years, no detector lasts forever.

  10. Response to Obvious Source • Evacuate the house • If any flu like symptoms, call 911 • Remove or turn off the source • Ventilate the house • Reset the alarm • Do not re- occupy house until alarm ceases • Take steps to avoid future situations

  11. Response to Unknown Source • Evacuate house • If any flu like symptomscall 911 • Do not ventilate home • Have qualified service technician inspect, repair all sources • Do not reoccupy home until those who tested say that danger is over

  12. Testing Your Detector • Test button • Once a week • Hold source of CO (match/lighter) 20 to 25 cm away from detector, watch to see display respond

  13. Relation • Ideal Gas Law - Can not be any other, not dealing with a constant number of moles • Pressure, volume, temperature change as number of moles changes • KMT – as number of moles increases in given volume number of collisions increases – pressure(^)
