Which gas is formed from the incomplete combustion of many common household products, including vinyl materials?

Phosgene is a toxic gas that can be produced from the incomplete combustion of various common household products, particularly those containing carbon and chlorine, such as vinyl materials. During the combustion process, if there is not enough oxygen available to fully oxidize these materials, phosgene can form. This gas is colorless and has a musty or hay-like odor, making it dangerous even in low concentrations.

Understanding the context helps to clarify why phosgene is a significant concern in situations where vinyl products or similar materials are burned; it highlights the need for proper ventilation and protective measures during any type of combustion involving these materials. In contrast, while formaldehyde, acetylene, and chlorine dioxide are important in their own right and can have toxic effects, they are not directly linked to the incomplete combustion of vinyl products in the same manner as phosgene.
