Portable monitors, deck guns, and ladder pipes are examples of what type of equipment?

Portable monitors, deck guns, and ladder pipes are classified as master stream devices. These devices are designed to deliver large volumes of water at high flow rates, which is essential for fighting fires in various scenarios, especially when there is a significant fire load or when it's hazardous to place firefighters close to the flames.

Master stream devices typically can be operated from a fixed position, such as a fire apparatus, and they are engineered to provide a powerful and wide-reaching stream of water. They are often used when situations require a concentrated and prolonged water application, which handlines might not be able to achieve due to limitations in both flow and maneuverability.

In contrast, handlines are smaller diameter hoses intended for direct engagement by firefighters and are more manageable in terms of movement and flow rates. Ventilation tools facilitate the removal of smoke and heat from a structure but do not directly contribute to fire suppression. Hose stabilizers are used to secure hoses in place and maintain optimal operation during deployment but do not directly emit water streams like master stream devices do.
