How high should a fire be to ensure safety in this context?

In the context of fire safety, the recommendation for the height of a fire is important for various reasons, including visibility and the safe dispersal of smoke and heat. A fire should ideally be at least 18 feet high to ensure that it provides adequate safety. This height allows for enough clearance to enable fire safety personnel to access the area without being exposed to the direct heat and flames. Additionally, an 18-foot barrier helps to minimize the risk of the fire spreading uncontrollably, as it can create a higher heat stratum that allows for better smoke ventilation and reduces the risk of backdrafts.

This height is aligned with standard safety protocols that are informed by both practical experience and regulations aimed at preserving life and property during a fire incident. Tactics employed at this height can also be effective in providing better suppression methods, as firefighters can maintain a safer distance and apply their techniques from a more advantageous position.
