Final answer:
The default value for the yield of carbon monoxide (CO) in a post-flashover fire is not provided in the provided information. Carbon monoxide is a dangerous byproduct of incomplete combustion and treatment for exposure includes rapid removal from the source and oxygen administration.
Step-by-step explanation:
The default value for the yield of carbon monoxide (CO) in a post-flashover fire is not explicitly stated in the information provided, and it usually requires specific environmental and combustion conditions to determine an accurate value. However, we can discuss carbon monoxide in relation to combustion reactions. In a combustion reaction such as the burning of carbon in limited oxygen, the main product formed is carbon monoxide, as shown in the chemical equation 2 C(s) + O₂(g) → 2 CO(g).
Carbon monoxide is an extremely dangerous gas because it interferes with the oxygen delivery in the body, causing a variety of symptoms including headaches, dizziness, and even death if not addressed promptly. Initial treatment for carbon monoxide poisoning includes removing the individual from the exposure and administering oxygen to reduce the half-life of CO in the bloodstream.
It's worth noting that the yield of a combustion byproduct like CO may vary depending on many factors like temperature, availability of oxygen, and the nature of the materials burning.
