When exposed to smoke, hydrogen cyanide may play a role in rendering firemen and bystanders incapable of performing self-rescue.
HCN is a toxin that spreads throughout the body; it is hazardous because it inhibits cytochrome oxidase, which stops cells from using oxygen. Loss of awareness, respiratory arrest, and finally death arise from inhibition of the last stage of electron transport in brain cells.
Higher HCN exposures cause cardiovascular collapse, tremors, cardiac arrhythmia (which may not manifest for two to three weeks after the fire exposure), coma, respiratory depression, and respiratory arrest. Inhaling minute concentrations of hydrogen cyanide can result in headaches, weakness, nausea, and vomiting. Larger doses might result in fainting, convulsions, gasping, fast pulse, irregular heartbeat, and even death. In general, the severity of the symptoms increases with the seriousness of the exposure.

Answer:
<em>Comparative analysis.</em>
Explanation:
The fundamental premise of the <u>comparative analysis </u>is that <u>research can reveal more about the subject of the study if a set of data about first subject is compared to the same set of data about another subject. </u>

A higher standard of living for the middle class was increasingly identified with the ability to purchase goods and products that were produced on a mass scale.
Explanation: After the Industrial Revolution, products were able to be both produced AND purchased on a mass scale by society.
The high quantity of a variety of quality goods readily available to citizens for purchase, with less labor from humans required due to the use of machinery to lighten the process, greatly increased the standard of living.
