A fire suppression system like restaurant fire suppression systems NYC may be the only answer when fire sprinklers fail. This is because fire suppression systems typically activate earlier than sprinklers. But when these systems fail, a few factors must be considered before purchasing a fire suppression system. Below are some things to consider. Keeping these in mind, you can choose the best option for your property. And as a reminder, you can learn more about the different types of fire suppression systems, including CO2 flooding and foam.
Clean agent systems
The primary objective of clean agent fire suppression systems is to protect the irreplaceable assets and the people in the facility. These systems use chemical agents such as FM-200, ECARO-25(r), and inert gases to extinguish fires quickly and efficiently without leaving residues that may harm the environment or people. These systems also reduce post-incident clean-up time and have a minimal impact on the ozone layer.
Clean agent fire suppression systems are fast-acting, reaching the required concentration levels in as little as 10 seconds. These systems also leave no residue, so they’re an excellent choice for occupied spaces that may contain sensitive items. Unlike traditional sprinklers, clean agents also offer low ozone depletion potential. They also help reduce fire damage to the building’s interior while preventing property damage. And since they’re eco-friendly, they’re also great for companies with sensitive equipment.
Wet chemical systems
Wet chemical systems for fire suppression are better than dry systems because they contain a chemical agent that can act as both a suppressant and a coolant. The coolant function is beneficial when extinguishing fires in heavy machinery since the area is more likely to be safe if flammable debris does not spread. A dry chemical system does not address this issue because it is not suited for hot engine fires.
Wet chemical systems for fire suppression protect a commercial kitchen from open flame, red hot cooking surface, and a heavily grease-laden environment. They also meet NFPA 17A and 96 standards. They are also highly effective in preventing fire spread. Wet chemical systems have many advantages. These include minimizing damage to kitchen appliances and reducing re-ignition. To protect your kitchen, purchase a system that meets the NFPA 17a and 96 standards.
CO2 flooding systems
One of the key functions of CO2 flooding systems in detecting smoke and fire. To do this, an alarm is triggered in the protected space. CO2 flooding systems are available in several types, with the most commonly used one being the high-pressure one. The system also features a time delay feature that delays the flow of CO2 for 60 to 90 seconds. This delay helps personnel escape the protected space. Next, a pressure gauge is installed on the common manifold and connected to the valve.
Carbon dioxide is non-flammable, odorless, colorless, and electrically non-conductive, which makes it the best fire-suppression agent. CO2 flooding systems have an exceptional capacity to rapidly disperse in hazardous areas, thanks to their high expansion ratio. Moreover, CO2 is environmentally friendly since it is a naturally occurring element in the atmosphere. Furthermore, this method can effectively control the spread of fire in a large area.
Foam systems
Foam systems are used to protect areas with flammable or combustible liquids. They are comprised of a bladder tank, proportioner, and foaming agents. The foam is mixed with water and air to create a vapor that separates the fuel from oxygen and forms a barrier against vapors. Generally, there are three types of foam systems: low-expansion, medium-expansion, and high-expansion.
The process of applying foam can be direct or forceful. A blanket of foam prevents fuel from agitating the foam and prevents its contamination by fuel. Foam blankets are most effective against fires involving Class B polar solvent liquids. While water has been used to suppress fires for centuries, it is often ineffective in oil fires and potentially dangerous. That’s why fire-fighting foams were developed.
Halon 1301
A fire protection engineer will look at various factors in the Halon 1301 fire suppression system overview. This can include the fire zone protection, modification potential of the platform, and other factors. The engineers will also look at the MIL-HDBK-1008C Military Handbook on Fire Protection for their design and construction work. While there are no specific NFPA standards or specifications for the Halon 1301 system, these factors should be considered in developing a fire protection system.
The Halon 1301 fire suppression system is available in two versions: the high rate discharge system (HRD) and the conventional one. In the former, the agent is discharged at a high rate using open-end nozzles, while the traditional system uses perforated tubing. High rate discharge systems typically meet the requirement of 250 milliseconds, but many halon 1301 systems exceed that time by about 100 milliseconds.
Pneumatic heat detection tubes
The basic function of a pneumatic heat detection tube is to detect the presence of heat. When a fire is detected, a small pressurized hole opens within the tube, releasing a suppressant. Upon detection, the system will activate the fire extinguishing agent through nozzles. Because they are independent of an electrical supply, pneumatic detection systems are great for high-temperature environments.
The fire suppression agent is pressurized through the tube inside the electrical cabinet bus bars. When the temperature reaches over 105 degrees Celsius, the tube breaks and discharges the suppressant agent. This system is highly effective in preventing fire and saving lives. In addition, pneumatic heat detection tubes can be installed inside electrical cabinets to provide dual valve outlets. However, it is important to note that a pneumatic heat detection tube should never be used in a commercial building unless you have an electrical fire suppression system in place.
