What is a cardox system?
The Cardox® Low Pressure Carbon Dioxide (LP CO2) fire protection system is a cost-effective solution used to protect areas that require multiple suppression cycles.
What is HP CO2?
The Kidde High Pressure Carbon Dioxide (HP CO2) System is ideal for industrial processes where flammable materials and vapors present a potential fire hazard. The Kidde HP CO2 System utilizes highly sophisticated electric and/or pneumatic detection units which sense fire at its inception.
What is CO2 suppression system?
Carbon dioxide or CO2 is a colorless, odorless, electrically non-conductive gas that is highly efficient as a fire suppression agent. Fike Carbon Dioxide fire protection systems use intelligent, reliable and fast-acting control panels to quickly sense a fire before it can cause damage to property.
Which CO2 system is used in passenger ships?
Low pressure CO2 storage for Ship fire protection systems. In some installations, the CO2 is stored in low pressure refrigerated tanks. The cylindrical storage vessels (Figure 14.17) are fabricated to the pressure vessel requirements of the authorities.
What is low pressure and high pressure CO2 system?
High-pressure CO2suppression systems store CO2in cylinders and are intended for smaller fires. Cylinders can hold up to 100 pounds per tank. Once discharged, there is no more CO2 in the tank. In contrast, low-pressure systems store CO2in one large tank versus several cylinders.
How does a CO2 fire suppression system work?
When a fire is detected, the CO2 suppression system will activate and discharge a blanket of CO2 into the area where the fire is present. The CO2 displaces the oxygen in the environment which will cause the fire to be extinguished.
What is low-pressure and high-pressure CO2 system?
Which gas is used in fire suppression?
Carbon dioxide
Carbon dioxide is incombustible and also does not support burning. Hence, it is used in fire extinguisher. When sprayed on burning object it stops the supply of oxygen and extinguishes fire.
What are the limitations of CO2 fire suppression systems?
One drawback to using carbon dioxide, however, is that its mechanism of fire suppression is through oxygen dilution, and not, as is the case for halon, through chemical disruption of the catalytic combustion chain.
Why 85% CO2 has to be discharged in the first 2 minutes in an ER flooding system Why 2 minutes not any other time?
CO2 fixed fire fighting system can be made so that it releases 85% of CO2 in 2 mins or even 95% in 2 mins: The discharge end nozzle has an orifice. Based on the orifice diameter, which is very important and this is what decides the criteria of rate of discharge of CO2.
How do you release CO2 from a ship?
In the CO2 release cabinet, open pilot cylinder valve first. Now open valve 1 for master valve first. Then open valve 2 for CO2 releasing mechanism. Co2 will be released after 60-90 seconds of time delay.
What is the temperature maintained in LP CO2 system?
Our low pressure carbon dioxide system is stored mostly as a liquid at approximately 300 psi (2070 kPa) and 0ºF (- 17.8ºC). It is maintained at this pressure and temperature by mechanical refrigeration.
What is the lifespan of a CO2 cylinder?
All composite cylinders have a 15-year service life in accordance with regulations around the world.
What is the best fire suppression system?
FM-200 is the best fire suppression system for a number of situations, including: Offices or other places where people may be present during a fire. FM-200 is non-toxic, and the health impact of a fire suppression system is always important in areas where crowds are frequent.
What does FM-200 stand for?
heptafluoropropane
FM200 is the commercial name given to it by its makers, DuPont. Its technical name is ‘heptafluoropropane’ and it is a colourless, odourless halocarbon.
What is the difference between FM-200 and CO2?
Not to be confused with a CO2 System, FM 200 fire suppression systems are electrically non conductive and safe for humans. FM 200 systems reach an extinguishing level within 10 seconds, making it one of the fastest and most effective means of stopping fires before they can cause significant damage.
What is Solas requirement for CO2?
For machinery spaces – 40% of the largest machinery space. This is excluding engine casing. 35% if including engine casing. For machinery spaces – 85% of the gas discharged in 2mins.
What should be checked immediately after activating the CO2 system?
3.2 Immediately after activation of the CO2 system checks should be carried out to ensure that the gas has been correctly released from the cylinders.
What is the minimum requirement for CO2 gas to release to fight a fire in engine room?
To obtain a total flooding of engine room, about 35% by volume of CO2 is required in 2 minutes. This will reduce the oxygen content of the air in engine room to less than 15% to extinguish the fire. At this CO2 concentration human life cannot be supported.
What pressure is CO2 stored at?
CO2 is transported, stored and handled in liquid form, either at ambient temperature (in cylinders or non-insulated storage tanks at a pressure of 45-65 bar) or refrigerated (in insulated tankers and storage tanks) at temperatures between -35 °C and -15 °C and pressures of 12 to 25 bar.
What PSI does CO2 turn to liquid?
The Liquid State:
Within a temperature range between -56.6 °C (-69,88 °F) and 31 °C (87,8 °F) and pressure greater than 5.2 bar and less than 74 bar (1’073,28 psi) respectively CO2 is in its liquid state except at very high pressures.
How do I know if my CO2 cartridge is empty?
How do I know if my gas cylinder is empty?
- Make sure the carbonating cylinder is tight enough and retighten it if necessary by twisting the cylinder to the right.
- If you’re still not getting bubbles and if you don’t hear a sputtering sound when you press the carbonating button*, you may be out of gas.
How often do CO2 tanks need to be tested?
every 5 years
Hydrostatic (Hydro) Testing is a process where components such gas cylinders are tested for strength and leaks. Aluminum CO2 cylinders require testing every 5 years. At the time of testing, a date stamp will be imprinted into the cylinder near the top of the tank.
How much is a fire suppression system?
If your project is new construction, expect to pay $1 to $2 per square foot of coverage. A high-rise building will be more expensive, averaging $2 to $4 per square foot of coverage. Existing buildings that will be retrofitted can average $2–$7 per square foot of coverage.
What are the four types of alternative fire suppression systems?
Alternative fire suppression systems are common in many commercial buildings throughout the United States. Wet-chemical, dry chemical, systems utilizing foam, clean agent, and carbon dioxide suppression systems fall under the general classification of alternative suppression systems.
