• Carbon Monoxide Detectors is a device that detects the presence of Carbon Monoxide (CO)
  • Excess Carbon Monoxide(CO) = Carbon Monoxide Poisoning
  • Silent Killer
  • Incomplete Combustion

History of Dalton’s Law

  • John Dalton (6 September 1766 – 27 July 1844) was an English Chemist, Meteorologist and physicist
  • He investigated and published the atomic theory which states
  • Elements are made of tiny particles called atoms.
  • The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative atomic weights.
  • All atoms of a given element are identical.
  • Atoms of one element can combine with atoms of other elements to form chemical compounds a given compound always has the same relative numbers of types of atoms.
  • Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.

Daltons Law

  • The pressure of a mixture of non-reacting gases is the sum of the partial pressures of the individual gases in the mixture
  • · PTotal = P1 + P2 + P3
  • The partial pressure is the pressure that one gas exerts on the sides of the container
  • Mole Fraction: PA = Ptotal x na

Daltons Law and CO

  • Partial pressure of CO is that of which would be Carbon alone and Oxygen alone
  • Pressure of Carbon and Oxygen combined = Total Pressure
  • Enclosed space causes increase in pressure
  • Dangerous if CO is not ventilated properly and confined in a small area

How do CO Detectors Work?

  • 3 Different Types
  • Colorimetric detectors
  • Metal-oxide detectors
  • Electrolytic detector
Autism and the Environment

How is CO Produced?

  • Carbon monoxide is produced from the partial oxidation of carbon-containing compounds
  • Operating Stoves and Internal Combustion engine in enclosed space
  • Using Air freshener after painting walls

What Does CO Do To Your Body?

  • Combines with haemoglobin.
  • Carbon monoxide is 200 times better at combining with haemoglobin than oxygen
  • At a level of 0.1%, carbon monoxide will kill us quickly
  • Carbon Monoxide Detectors & Economy
  • High demand = High price
  • Required in many places
  • Large profit for many businesses
  • Carbon Monoxide Detectors & Society
  • Many individuals educated about risk
  • Apart of curriculum for fire fighters
  • Many take part in learning how to install and repair detectors

Carbon Monoxide Detectors & Environment

  • Many detectors now made environmental friendly
  • They can cause risk to environment if not functioning proper
  • Must be disposed of carefully if there is CO still trapped inside
