What is HI-FOG system?

What is HI-FOG system?

HI-FOG fights fires with significantly less water but just as effectively as traditional sprinkler systems. In a nutshell, HI-FOG® cools the fire and the surroundings, blocks the radiant heat and eliminates the oxygen from the seat of the fire.

What is a water mist fire suppression system?

A water mist system is a fire protection system which uses very fine water sprays (i.e. water mist). The small water droplets allow the water mist to control, suppress or extinguish fires by: cooling both the flame and surrounding gases by evaporation. displacing oxygen by evaporation.

Where are water mist fire suppression systems found?

Typical applications, we see them going into some data centers out there, museums and theaters. Some historic homes have chosen water mist systems to have less water damage, and then large office buildings, so buildings companies are building that are high technology users.

Why do firefighters use mist?

It has the added benefit of shielding firefighters; the cloud of mist is very effective at absorbing radiated heat that can otherwise make it impossible to get close to a major fire. Water mist has its limitations. Freezing temperatures can be a problem, especially in remote outdoor sites such as oil wells.

What is mist system?

Misting systems are most commonly defined as a series of specially mist nozzles placed in a line around the perimeter of an area. When misting systems are placed inside an enclosed area (such as a greenhouse), the billions of droplets that are produced will initially provide cooling as the droplets evaporate.

What two mechanisms are used in a high fog system to combat fire?

HI-FOG® uses three mechanisms to fight fire: cooling, radiant heat blocking and local oxygen inerting. Traditional sprinkler systems use wetting as their main mechanism, and therefore use very large amounts of water.

What are the problems with water mist systems?

Not only will water mist systems control room temperature and convert the droplets into steam, suffocating the fire, but water damage from water mist systems as compared to ordinary water sprinklers is lowered considerably.

How does water mist work?

Water mist systems use highly pressurized water and specialized sprinkler and spray heads to dispense water as small droplets, or mist. The more numerous the water droplets, the larger the water surface area exposed to heat. More drops will evaporate and turn to steam that will then absorb more heat.

Is a water mist system a sprinkler system?

The major difference between sprinklers and mist systems is that a sprinkler system has standards for the components of the system and their design and installation, whereas, at the moment, water mist systems do not.

How do water mist systems work?

Do misters help with smoke?

One of the more industrial benefits of a misting system is its ability to control dust and minimize smoke or airborne pollen or control humidity levels.

Which extinguishing agent is best for use of a magnesium fire?

Class D extinguishers
Use approved Class D extinguishers or smother with dry sand, dry clay, or dry ground limestone and dry graphite. DO NOT use carbon dioxide or halogenated extinguishing agents. DO NOT use water or foam.
