The role of the stage fire machine

1. Fire prevention and early warning

Real-time monitoring of fire hazards: Through built-in smoke sensors, temperature sensors and other equipment, the environmental parameters of the stage area (such as stage scenery, lighting equipment, and electrical wiring dense) are continuously monitored. When the smoke concentration exceeds the standard or the temperature rises abnormally, it can quickly send out an early warning signal to remind the staff to investigate hidden dangers in time to avoid fire accidents.

Electrical safety monitoring: Some high-end stage fire extinguishers can monitor the current and voltage of high-power electrical equipment such as stage lighting and sound to prevent fires caused by overload and short circuit of the line.

2. Initial fire fighting

Rapid response to fire extinguishing: In the initial stage of the fire, the stage fire extinguisher can automatically or manually start the fire extinguishing device, such as spraying water mist, foam and other fire extinguishing agents, to quickly control the spread of the fire. For example, in the event of a fire on flammable materials such as stage curtains and props, the sprinkler system of the fire extinguisher can cover the fire source at the first time and reduce the intensity of the fire.

Adaptation of multiple fire extinguishing methods: According to the characteristics of the stage scene, the fire extinguisher may be equipped with different fire extinguishing media:

Water mist fire extinguishing: It is suitable for electrical equipment areas to avoid short circuits caused by traditional water spray, and at the same time cool down and isolate the air through fine water mist.

Foam extinguishing: In the event of a fire caused by grease or liquid fuels (such as flammable liquids used in stage special effects), foam can cover the liquid surface and stop combustion.

Gas fire extinguishing: In a closed stage equipment room (such as a lighting control room), gas fire extinguishing agents such as carbon dioxide or heptafluoropropane can be used to quickly suffocate and extinguish the fire without leaving residue.

3. Ensure the evacuation and rescue of personnel

Evacuation guidance assistance: The fire extinguisher is usually linked with the emergency lighting and evacuation indication system of the stage, and automatically lights up the emergency lights and turns on the evacuation indication signs in the event of a fire to guide the audience and staff to evacuate along the safe passage. Some devices can also issue a voice alarm to remind the evacuation direction and precautions.

Prevent the spread of fire: By setting up fire separation facilities (such as fire shutters and water curtain systems) at key locations between the stage and the audience, and in the backstage area, the fire fighters can automatically activate these devices in the event of a fire, forming a physical barrier, delaying the spread of the fire and buying more time for personnel to evacuate.

Create conditions for rescue: During the fire extinguishing process, the water spray or smoke exhaust function of the fire extinguisher can reduce the on-site temperature, remove smoke, improve the working environment of rescuers, and facilitate firefighters to enter the scene to carry out fire extinguishing and search and rescue work.

Fourth, the stage special effects safety control

Safety of special effects scenes: Special effects such as fireworks, cold fireworks, and dry ice spray are often used in stage performances, and there is a risk of fire in these links. The fire extinguisher can monitor the use area of the special effects equipment in real time, and start fire prevention measures (such as pre-spraying water to cool down and setting up automatic coverage of the fire blanket) when the special effects are started, so as to ensure the safety of the special effects performance.

Linkage control of special effect equipment: When the fire extinguisher detects a fire signal, it can automatically cut off the power or gas source of the special effect equipment to prevent the fire from being aggravated by the operation of the special effect device.

5. Linkage with the stage fire protection system

Integrated fire protection network: The stage fire extinguisher is usually a part of the entire stage fire protection system, and works in conjunction with the automatic fire alarm system, fire hydrant system, smoke prevention and exhaust system, etc. For example, when the fire alarm system is triggered, the fire extinguisher immediately starts to extinguish the fire, and the smoke prevention and exhaust system is turned on at the same time to remove the smoke.

Remote monitoring and management: Through the central control system of the fire control room, the staff can remotely monitor the operation status of the stage fire extinguisher, obtain early warning information in real time, and remotely control the start, shutdown and fire extinguishing mode switching of the fire extinguishing machine, so as to improve the efficiency of emergency response.

6. Other auxiliary functions

Daily fire drill support: The stage fire extinguisher can simulate fire scenarios in daily fire drills, test the response speed of fire extinguishing devices and the effectiveness of evacuation processes, and help staff familiarize themselves with emergency response processes.

Environmental data recording and analysis: Some fire extinguishers have data storage functions to record historical monitoring data (such as temperature and smoke concentration change curves) to provide data support for stage fire safety management, which is convenient for later analysis of hidden danger laws and optimization of fire protection measures.
