Abstract

This paper delves into the experimental comparison of the efficiency of the fine spray and water mist firefighting systems applied for the interior fire attack. The two systems such as a high-pressure firefighting module "ENEY-10/30" and a combination fire nozzle Protek 366 connected to a rescue firefighting vehicle by a firehose were compared. The interior fire attack was tested into a container based fire simulator. A special measuring system was designed to evaluate the efficiency of the systems. During the studies, humidity and temperature at different points of the fire simulator were measured. DHT22 temperature and humidity sensors were located at a distance of 1.5 m from each other at different heights of 1.0 m, 1.5 m and 2.0 m. The time-history of the humidity and temperature were investigated during the interior fire attacks. Based on the research data, it was established that it is reasonable to use the “ENEY-10/30” module at the initial stage of firefighting to suppress the fire and reduce the temperature inside the container. The Protek 366 nozzle can be used then as an effective means for a direct firefighting attack.
