What is the minimum number of people required for vertical ventilation?

Vertical ventilation is a technique used in firefighting to help remove smoke and heat from a burning structure, allowing for safer conditions for both firefighters and potential victims. The process involves cutting holes in the roof or upper levels of a building to facilitate the outflow of smoke and heat.

The minimum number of people required for this operation is two. This is because ventilation often requires coordination and safety measures. One person typically operates the cutting tool or manages the ventilation, while the second person assists with safety, controls the area below, and ensures that the operation can be completed effectively and efficiently. Having two individuals reduces the risk of injury, ensures that someone is available to call for assistance if needed, and allows for effective communication during this critical operation.

Fewer than two people could compromise safety and effectiveness, particularly in the unpredictable conditions that accompany firefighting operations. Thus, requiring at least two individuals is a standard practice to ensure successful vertical ventilation.
