Due to hot weather and common fires occurring from time to time, Australia Fire Services have taken steps to avoid them. Remember the great big Australian Bush Fire of 2019 to 2020? People are taking care that such instances do not happen again. Several million hectares were burned in Australia. People lost their jobs, homes and some loved ones and some lives. With so many of these disasters taking place like that, it is inevitable that it is going to happen again. People have come with ideas and solutions to prevent and prepare fires. Australians have also taken their products abroad to enhance them. And these ideas include:
- Atmospheric Oxygen Depletion Systems:
Fire usually requires oxygen in the air to keep burning in addition to combustible fuel. Without oxygen, fires die out quickly. And that’s the strategy used by an atmospheric oxygen depletion system. These systems are, as a result, very efficient at extinguishing indoor fires.
But can it kill a person due to lack of oxygen? The oxygen in the air is usually 21%. The Atmospheric oxygen depletion systems usually reduce the oxygen levels to 18.5% in volume that usually sinks below. This is enough for a human being to survive easily. A human being only falls unconscious at 13% to 10% of oxygen in the air and will die only if the oxygen levels drop to lesser than 6% in volume.
- Video Smoke Detection Systems:
Video smoke detection systems are capable of finding smoke even if no one is present in the room. This is done by a software system that works in cameras. They rely on black and white images, sometimes thermal imagery, to detect smoke and fires. More advanced options include infrared-sensitive with IR illuminators that can work in the dark as well. Thermal imagery is very effective and can detect fires and smoke through walls.
- Barometric Fire Detection Systems:
A barometric fire detection system physically detects changes in the pressure of the air and temperature to know if there is a fire around. When the detector is adjusted according to the system’s requirements, the onboard sensors are able to react to the fire perfectly. In case of a malfunction where the pressure sensor does not match the required value of the system,
the barometric fire detection system, an indication takes place to mention a fault.
- Ultrasonic Liquid Level Indicator:
As the name suggests, ultrasonic technology is used here. It detects the air and liquid in any single-layered container. There are two types of sensors; the dry sensor and the wet sensor.
- The ‘Dry’ sensor: It does not need any sort of liquid or gel for good ultrasonic signal transmission.
- The ‘Wet’ sensor: This type of sensor requires an ultrasonic gel to be applied to cylinders in poor condition where the coating has been worn out or is irregular and rusty surfaces. This should prevent the sensor from picking up a clear signal.
These sensors are mounted in a magnetic applicator that works with good contact and is completely hands-free.
