Carbon monoxide (CO) is an odorless, colorless gas that is produced by incomplete combustion of carbon-based fuels. It can be deadly even at low levels by displacing oxygen in the bloodstream. Common sources of CO include vehicles, heating systems, appliances, and any fuel-burning devices. Specialized monitoring equipment is needed to detect CO since it has no warning properties. Responders must follow sampling procedures and monitor CO levels to safely respond to incidents and ensure no further exposure or health hazards.

Carbon monoxide is a colourless, odourless and tasteless gas existing in a miniscule concentration in the atmosphere (< 0.001%), and is a product of partial combustion. Carbon monoxide poisoning is associated with a high incidence of morbidity and mortality. Symptoms are usually non-specific and include fatigue, headache, dizziness, nausea and vomiting, cognitive impairment, and tachycardia; mimicking an influenza-like illness. Symptoms occurring in more than one person (belonging to the same family/office) simultaneously and the relief also occurring at the same point of time in them should sound the physician's mind for suspected carbon monoxide poisoning. A high index of suspicion and presence of a source of generation of carbon monoxide are the diagnostic aids which can be confirmed by blood carboxyhaemoglobin levels. Removal from the source of carbon monoxide generation, moving the person to fresh air immediately is most important. In the emergency room, oxygen therapy is the key. Immediate treatment with a high fraction of inspired oxygen and careful clinical evaluation are mandatory for effective management. Patients with a carboxyhaemoglobin level of 10% or more should always be treated and 100% oxygen for 8 hours is recommended for patients requiring artificial ventilation. Hyperbaric oxygen also holds promise in select cases specially those with a history of unconsciousness, cardiovascular instability or ischemia, persistent mental and/or neurologic deficits and probably in pregnant patients

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

4. Carbon Monoxide (CO) Properties Flammable Gas: DOT Designation Auto ignition temperature = 1128° F Lower Explosive Limit 12.8% Upper Explosive Limit 74% Vapor Density of .968 Slightly less than that air CO will rise with warm air CO disperses evenly once it cools
11. Carbon Monoxide (CO) Sources Appliances Vented: appliances that are designed to be used with a duct, chimney, pipe or other device that carry the combustion pollutants outside the home. Un-vented: appliances that do not vent to the outside, so they release combustion pollutants directly into the home.
12. Carbon Monoxide (CO) Sources Levels of CO in homes: Average levels in homes without gas stoves vary from 0.5 to 5 parts per million (ppm). Levels near properly adjusted gas stoves are often 5 to 15 ppm and those near poorly adjusted stoves may be 30 ppm or higher.
13.
14. Where to Sample???? Follow search procedures Sample around all un-vented appliances (stove, ovens & space heaters) Sample in heat exchanger exhaust ports of furnace Sample under draft diverter of an atmospheric hot water heater Sample anywhere you may suspect CO (Garage, basement, etc….)
15. Health Hazards Silent Killer: CO will kill before its presence is known No early warning signs Displaces O2 in the bloodstream Victims die from asphyxiation
16.
17. Health Hazards Absorbed into the body through lungs Transferred to the blood Combines with hemoglobin to become carboxyhemoglobin (COHb) CO poisoning is measured by the % of COHb in the blood
18. Health Hazards Reduced O2 reduces functions of the brain, cardiac muscle, and respiratory system CO has a greater affinity for hemoglobin than O2 at 210 times to 1 COHb limits the ability of the blood to carry oxygen and effects all major organs and muscles.
19. Health Hazards Individual CO poisoning levels depend on several factors Initial COHb concentration Concentration of CO inhaled Length of exposure Activity while inhaling CO Body size and physiological factors
20. COHb Levels of Concern %COHb Levels Symptoms 0-10% None 10-20% Tension in forehead 20-30% Headache 30-40% Severe headache, nausea, vomiting, dizziness 40-50% Increased respiratory, pulse rate. Asphyxiation 50-60% Coma, convulsions, Cheyne-Stokes respirations 60-70% Weak respirations and pulse; possible death 70-80% Slowing and stoppage of breathing. Poss. death 80-90% Death in less that one hour 90-100% Death within a few minutes.
21. Carbon Monoxide (CO) Levels CO Levels Effects 128,000 PPM 12.8 % = LEL 12,800 PPM 10% of LEL – 10,000 PPM Un-consciousness & Death 1-3 minutes 6400 PPM Death or irreversible damage in 10-15 minutes 3200 PPM Dizziness & Headache 5-10 minutes 1500 PPM IDLH (immediately dangerous to life or health) 1300 PPM Cherry red skin and violent headache 400 PPM STEL 1-2 hour, Headache and nausea after 1-2 hour (short term exposure limit) 200 PPM Possible mild headache after 2-3 hours 35 PPM TLV-TWA PEL (threshold limit value) (OSHA) “Gwinnett Standard” 10 PPM Gwinnett Standard for “Structure Fires” SCBA Removal 9 PPM EPA: Maximum acceptable level of CO inliving space When do we pack up at a CO incident? Why? When do we need to back out of a CO environment?
22. Atmospheric Monitoring Equipment CO Monitors Direct Read What you see is what you get. Firefighter Proof! What type of Firefighter are you? A want to know how it works firefighter? A just tell me what to do when it makes noise firefighter?
23. PPM, Percent and What it means? Defining PPM – Parts Per Million "Parts per Million" is a way to quantify very low concentrations of substances. For example, 1 ppm is equivalent to 1 milligram of something per liter of liquid (abbreviated as mg/L) or 1 milligram of something per kilogram of solid substance (abbreviated as mg/kg). In terms of percentage, 1 ppm equals 0.0001 percent. 1% = 10,000 ppm If your O2 changes one percent you have 10,000 ppm unaccounted for many toxins are fatal at 150 ppm. If you have 1,000,000 golf balls and 17 of them are red what is your PPM? If you have 1,000,000 golf balls and 10,000 of them are red what is your percentage?
24. Atmospheric Monitoring Equipment Sampling Techniques Zero the instrument in fresh air Sample at entrance prior to entry Sample at various heights upon entry Sample near location of CO alarm and in and around all appliances that use or cause combustion and any other location in which CO may be present
25. Summary Carbon Monoxide (CO) is an ever present danger. To be properly prepared to respond to such an emergency we must have a thorough knowledge of our enemy: what he is, where he lives and how he harms us. Understanding that we must be able to appropriately apply learned response guidelines in order to SAFELY respond to and mitigate the problem at hand. It is essential that we use appropriate procedures when responding to incidents involving CO to ensure that we accomplish our primary mission of “Everyone Goes Home!!!”
