Gas stoves emit CO and this can become an indoor health hazard. Consider an energy efficient 595 m 3 home with 0.03 ai r exchanges per hour infiltration rate. Suppose the power goes off one winter and you turn the oven and 2 burners on to heat the kitchen to stay warm. The CO concentration of outside air is 0 .0 ug / m 3 and initially there is no CO in the home either . As sume that the air is well mixed in the house. The oven emits 1900 mg/hr and each burner emits 1840 mg/hr.
a . The oven and two burners are on for 4 hours from 3 - 7 PM. Estimate the CO concentration in the home at 7 PM.
b. What is the steady state CO concentration? c. Given the steady state CO mixing ratio in part above (assume 1 atmosphere pressure and 288 K) what is the resulting %COHb and what is the health impact if exposed to this concentration overnight while you slept ?
