Fire Suppression

Fire SuppressionSystems

The best way to safeguard your business from fire, reduce the risk of damage to your facility and its contents, and keep occupants safe, is by investing in a fire protection system. Partnering with a company that understands the needs of your property is key. From design to installation, maintenance, inspection, and repair, Ahern has a team of NICET certified designers, in-house fabrication resources, and experienced field teams to meet your project needs.

Installation &Service

Our special hazards fire protection systems, or alternative suppression systems, often protect businesses’ mission critical spaces, such as data centers, computer rooms, process chemical areas, and more. These areas are referred to as ‘mission critical,’ because their continued operation is critical to the lifeblood of the business they support. In the event of a fire, these mission critical areas require non-water based protection systems to remain operational. Our long résumé of mission critical successes allows us to quickly identify the proper systems for your unique space, and efficiently move through design and installation. Because we are fluent in the requirements of over 50 NFPA and IBC codes, engineers and building owners alike often rely on our expertise regarding unique occupancy based hazards.

Many fire protection applications require alternative suppression systems for areas or critical equipment where standard, water-based systems are not the desired approach. Ahern’s special hazards service team is trained to identify and inform you of potential problems or code compliance issues that may adversely impact your alternative suppression systems. For the past seven years, our fire protection employees have annually received over 1,600 hours of special hazards training. This enables our team to act as an advisor to building owners regarding requirements for unique occupancy based hazards.

As of 2019, we employ over 30 special hazards fire protection professionals who average 19 years of industry experience

Ahern was a pleasure to work with. We were very impressed with the forethought that the team brought to each project meeting. This attention to detail helped to keep the entire project on schedule, and provided a full understanding of what needed to be done. We are very happy with the work that Ahern performed.

Carbon Dioxide

Carbon Dioxide

Fire suppression systems come in many forms, but they find use when fire sprinklers are not preferred. A carbon dioxide fire suppression system pumps a high density of CO2 into a given area and lowers the level of oxygen available for the fire to continue combustion.

Inert Gas

Inert gas suppression systems are important fixtures in a variety of facilities for their ability to suppress flames without damaging assets with water.

Foam Fire Suppression

Foam fire suppression systems are typically used in larger, open spaces and work through a combination of factors to suppress fires before they can spread.

Wet Chemical

Wet chemical fire suppression systems meet the needs of our commercial cooking customers applications including but not limited to fryers, griddles, range tops, etc.

Explosion Suppression

Dry Chemical

When working around a variety of highly flammable materials and liquids typical hazards would include open-faced booths, auto paint booths, and paint mix rooms where a versatile fire safety system is needed.

Clean Agent

Clean Agent

When mission-critical assets must be protected in the event of a fire, sprinkler systems can compound the damage caused by smoke and heat.

Watermist Fire Suppression

Watermist fire suppression systems work by using very small droplets of water to cool the flame as well as the surrounding gases that are fueling the fire. 

Explosion Suppression/Venting

Explosion protection systems are a product line many will never deal with or even knew existed. Explosion risk is present with many industrial process facilities involving food, grain, pharmaceuticals, power generation, aerosol filling, wood, or other flammable vapors or combustible dusts in confined vessels or spaces. These sophisticated systems are designed to detect an event within milliseconds by watching for either a flame, with high-speed optical flame detectors, or the pressure wave in front of the flame with pressure detectors. By rapidly injecting a suppression agent into the space or volume, the heat is removed from the flame front as it consumes the fuel, thus stopping the event.

Another method of dealing with explosion risks is venting of explosion pressures and flame to a safe area outside via explosion relief vents.

Spark/Ember Suppression

Spark/Ember Suppression systems are typically used to stop small sparks and embers traveling in industrial ducts used to carry flammable dusts and materials to processes or filters and collection equipment.

Working with a system of very sensitive optical sensors and water spray assemblies within the ducts, the small glowing embers or sparks are detected as they travel down the duct or pipe in the airstream. Before they can make their way to the process or filter, a curtain of fine water is injected into the duct or pipe to quench and remove the heat or energy from the particles. The systems are designed to cycle on and off as needed, only stopping the process when excessive quantities of sparks or embers are seen. The systems are designed to remove the sources of energy, as a preemptive strike that could result in a fire event or explosion if not addressed.

2.9M

Ahern has protected over 2.9 million square feet of data center, telecommunication, and other mission critical equipment space since 2004.

I am pleased with the work that Ahern completed and I would use them again.
