What is used to prevent the spread of fire?

The most effective means to prevent the spread of fire involves establishing boundaries. These can include fire walls, fire breaks, and other physical barriers designed to limit the ability of flames and heat to move from one area to another. By using boundaries, space can be created that does not support combustion, thus slowing down or even stopping the progression of a fire.

While fire extinguishers, water hoses, and sprinkler systems are critical tools in managing and controlling the fire once it has started, they do not constitute a means of prevention. Instead, they are reactive measures designed to address an active fire situation. The strategic use of boundaries is akin to creating a controlled environment where risks are mitigated before a fire can even start or expand. This proactive approach is essential in fire safety and management.
