Commercial Fire Safety Systems Australia: Case Studies

By stacy 13 Oct, 2017

A strong knowledge of strategies to prevent or limit fires on industrial and commercial sites is essential for engineers and designers as they seek to minimise risks for their clients. Here are some key factors to understand.  

1. Environmentally friendly foam suppressants

Stopping an out-of-control fire is one thing – doing it in a way that minimises fallout for the environment is another. The latest foam suppression concentrates can protect business assets from fire risk without contaminating the surrounding land, air and waterways. A range of synthetic and biodegradable protein firefighting foams are suitable for a variety of scenarios, including wildfires, aviation, petrochemical and marine events.

 Proportioning systems such as water-driven foam dosing of fires is renowned as a way to extinguish fires faster while reducing a blaze’s environmental impact. Such techniques are cost-effective and provide peace of mind for environmentally aware site managers.

 

2 . Fire-safety arsenal for wind turbines

With renewable energy sources now in vogue, applications such as wind turbines are increasingly being used. They need reliable fire protection measures as the risk of burning debris falling to the ground and setting alight the surrounding countryside can be catastrophic.

 The solution is specialised tube-based systems. One of the most effective and environmentally friendly solutions is Firetrace’s linear pneumatic system which provides both fire detection and suppression in a single, self-contained package. It uses a fire-protection fluid that, when discharged, turns into a colourless and odourless gas that disperses naturally, leaving no residue that could damage sensitive electrical equipment.

 

3. Pre-engineered systems for commercial kitchens

Some fires in commercial kitchens are inevitable, but with the right advice and equipment from an experienced fire-prevention expert the aim is to quickly detect and suppress kitchen fires before they take hold. Pre-engineered systems such as Ansul R-102 – the world’s most popular kitchen fire-protection solution – use advanced suppression agents that have three vital characteristics: fast flame knock-down; vapour securement; and the ability to cool hot surfaces and cooking oils.

 The system can be triggered manually or automatically, and affected areas simply have to be flushed out with water or steam after a fire – meaning that the kitchen can be back up and running very quickly. It meets all the relevant Australian and international standards and can be retrofitted to existing kitchens.


  4. Spray systems for the mining industry

Fires in heavy mobile equipment on mining, forestry and other industrial sites can lead to costly machinery damage and operational delays. However, specially developed vehicle fire-protection systems such as the acclaimed Amerex DCP/ICE vehicle suppression system can limit the fallout. It features linear or spot detection devices which are located in at-risk areas of the vehicle.

 Heat causes a control module to alert vehicle operators and activates dry chemical extinguishing agents and/or foam spray systems to put out the fire. It is important to seek the assistance of a reputable fire-prevention expert who can assist clients with the commissioning and installation process.

 

5. Advanced fire monitors

Prevention is always the best cure, so choosing and using the right fire monitor can make all of the difference when it comes to warding off fire disasters. There are essentially two types of monitors – fixed and mobile. The choice can have serious implications for users, but it is not always a straightforward decision. Fixed monitors are attached permanently to pipework and are positioned to attack a fire at a specific risk point.

 They typically target flammable liquids such as petrol, diesel, methanol etc. on sites including petrochemical refineries, LNG facilities, tank farms, fuel distribution depots and loading jetties. A major benefit of a fixed monitor is that it can be activated and used to fight a particular fire faster than a mobile unit, which has to be transported. However, mobile monitors are versatile and can be trailer mounted or positioned by hand for fast deployment in a range of scenarios. As with any fire risk, it is important to discuss the best option with highly qualified professionals with extensive technical expertise who can assess your business requirements.

The Challenge: IT System Fire Protection

At Queensland Health's recently redeveloped and extended Mackay Base Hospital in north Queensland the main IT server room need a fire protection system installed. The server equipment housed in the room is of vital importance to the smooth running of the hospital’s complex administration underpinning the wellbeing of both in-patients and out-patients. Its loss or damage following a fire could potentially have dire consequences.

The Solution: Fire Suppression & Control via Fluid Clean Agent Suppression System

Delta Fire installed a solution that ensures a reliable, swift and effective response to a fire, one that causes no damage to the delicate electrical equipment being protected and enables a fast clean up after a fire. It was also imperative that this solution should not endanger the lives of any occupants of the server room that might be present if a fire breaks out.

Originally, the hospital had intended to install an inert gas suppression system. However, such systems require a large storage area for the suppression agent storage cylinders. As an alternative to meet the requirements, Delta Fire recommended a solution that has been used worldwide for numerous similar applications – Janus Fire System’s Novec 1230 Fluid clean agent suppression system.

Unlike an inert gas system, Novec 1230 is stored as a low vapour pressure liquid that, when discharged, converts into a colourless and odourless gas. It is electrically non-conductive, leaves no residue following discharge and, significantly, requires a quarter of the storage space, which is an important consideration in a hospital environment where space is always at a premium.

The Outcome: Fire Suppression System With Minimal Damage to IT Hardware

The Janus solution supplied by Delta Fire also has a highly desirable and respected environmental profile, particularly when compared with other gaseous suppression systems on the market. Novec 1230 Fire Protection Fluid has zero ozone depletion potential, a global warming potential of just one and a short five-day atmospheric lifetime, and so does not have any appreciable impact on climate change. It also has a large margin of safety for occupied spaces thanks to its low design concentration.

Six of Sydney’s premier fish restaurants at the iconic Sydney Fish Market in Pyrmont have taken a major step towards providing a safe dining experience for customers and a safe working environment for employees.

The challenge: Protect Commercial Kitchens From Fires Caused by Grease Build Up

Nicholas Seafood, the Sushi Bar, Peter’s Fish Market, the Fisherman’s Wharf Seafood

Chinese restaurant, the Fish Market Café and Christie’s Seafood all faced a similar

problem — to provide kitchen staff and customers with reliable, swift and effective

kitchen fire protection.

The iconic Sydney Fish Market is the largest market of its kind in the Southern Hemisphere, and its fish restaurants are a magnet for food lovers visiting the New South Wales capital from across the world. So much so that the Market is rated as being one of Sydney’s top visitor attractions

Deep-fat fryers use flammable cooking oil, which can result in grease build-up in hoods and ducts if they are not properly cleaned on a regular basis. If this grease build -up ignites, it can contribute to the swift spreading of a fire. The three primary types of equipment involved in restaurant cooking fires are deep-fat fryers, cooking ranges and cooking grills

The Solution: Retrofit Wet Chemical System to Kitchen Cooker Hoods

A total of eight systems were installed and, in every instance, they were retro-fitted to the existing kitchen cooker hoods. All of the installations took place outside of trading hours so as to not disrupt kitchen operations or inconvenience any of the diners. The world’s most highly regarded and widely used commercial kitchen fire safety system was chosen for the projects. It is a wet chemical system, with a suppression agent specially developed to suppress kitchen fires. It delivers fast flame knock-down, vapour securement and cooling of hot cooking surfaces and cooking oils. The system operates automatically to protect the cooking appliances, hoods and ductwork.

The Outcome: A World Class Commercial Kitchen Fire Protection System

The system used in the Fish Market restaurant kitchens achieves the highest fire safety standards and complies with the most stringent Australian and international codes and standards. Similar systems have been installed in Sydney at the Opera House, the Waterside Restaurant and in several restaurants at The Star casino venue.

The Challenge: A Limited Release Fire Suppression System that meets EPA Requirements

Brisbane Airport’s recently introduced an environmental protection policy whereby hangars will be approved only if their design prevents the release to the environment of any pollutants spilled inside the hanger. At a new 2500 square meter five start aviation hanger at Brisbane airport Delta Fire was contracted to install a firefighting system which need to meet the new environment protection policy standards.

The Delta Fire installation needed to overcome the many shortcomings of both AFFF deluge systems and oscillating foam monitors. These include their lack of speed in extinguishing a typical hanger fire, the excessive amount of water used and unnecessary or excessive discharges of foam that have caused costly damage to aircraft and the unacceptable release of foam into the environment.

The Solution: Automated Foam Deluge System using High Expansion Concentrate

Delta Fire’s system facilitates ARFF and QFRS (Queensland Fire & Rescue) operations and complies with the Australian Building Code. It is a foam deluge system that is triggered by triple infrared flame detectors and uses a special high-expansion concentrate that is discharged via 36 high-level generators.

In addition to not requiring an electrical supply, the solution does not require external air for foam production – the system creates foam from smoke gases, smoke-contaminated air and hot air. This leads to a rapid decease in temperature in the hanger as the hot aired is cooled in the generators, where it is aspirated and sprayed with water from the generator nozzles. Smoke emissions are reduced and fire ventilation is unnecessary.

The solution requires less than 1000 litres of concentrate to operate the system for 15 minutes, delivering about 2000 cubic metres a minute of the bio-degradable foam at an expansion ratio of between 650:1 and 700:1. Significantly, this is just one percent of the water that would be used by a comparable foam monitor installation. The system delivers a foam blanket across the hanger’s entire 50-metre by 50-metre floor area at the rate of 0.85 metres-a-minute or 0.3 metres deep in 21 seconds. A further 15-minute supply can be activated manually.

The flame detection system is configured to require two detectors to register the fire before the foam is discharged. However, discharge of the foam ceases as soon as fewer than two flame detectors no longer register the presence of a fire.

The hanger floor slopes towards a drain at the hanger door. Any liquids are collected in this drain and are contained in an underground tank beneath the fire pump house for licensed disposal off-site. This tank has a capacity to store approximately 61 cubic metres; more than sufficient to contain the 49 cubic metres of a 15-minute foam discharge and any other drained liquids. This compares with traditional hanger fire protection systems that would require tanks with capacities of between 300 cubic metres and 500 cubic metres.

The Outcome: An EPA-Compliant, Innovative Fire Suppression System

The system is believed to be the first of its kind in Australia, it complies with Brisbane Airport’s recently introduced environmental protection policy whereby hangars will be approved only if their design prevents the release to the environment of any pollutants spilled inside the hanger – including fuel spills, contaminated water and foam. A full-scale commissioning test was witnessed by both Brisbane Fire & Rescue and the Brisbane Airport’s ARFF (Airport Rescue & Fire Fighting) personnel.

The Challenge: Integrated Fire Fighting Systems, Maintenance & Testing

The Caltex oil refinry, on banks of the Brisbane River, is a high-hazard environment where crude oil is refined into petrol, diesel, jet fuel and base oils for lubricants and specialist products that include liquid petroleum gas (LPG) and bitumen. Due to this process the site needs reliable and effective firefighting measures and constant diligence.

As Australia’s largest oil refiner,  Caltex neeeds the  sophisticated firefighting equipment with that needs regular and professionally conducted maintenance to ensure that this equipment is in constant “as designed” readiness.

The Solution: A Range of Fire Protection Systems & Equipment, Plus an Ongoing Testing & Maintenance Program

As fire prevention at the site has the highest priority, Delta Fire worked with Caltex to supply the refinery with a wide selection of world-class firefighting agent delivery systems and hardware. Delta Fire has been commissioned by Caltex with essential maintenance, testing, servicing and equipment refurbishment work across the Lytton complex to ensure that the site is ready should a fire occur. Delta fire also conducts training exercises and regular risk assessments.

The Outcome: High Volume Skum Foam Monitor Systems, Monthly Testing & Maintenance

At the Lytton refinery Delta Fire has worked on ten high volume foam monitors. These include remotely-controlled Skum foam fog / jet monitors protecting the crude oil wharf that are positioned as high as 20 metres above ground level and are exposed constantly to a harsh and corrosive sea water environment. Similar Skum monitors are located at the rear of refinery’s product wharf, along with a number of monitors that are positioned strategically in readiness to provide a screen to cover escaping gas, all of which are also maintained by Delta Fire.

Delta Fire is also responsible for maintaining, servicing and carrying out monthly tests on a number of water sprinkler fire suppression systems that are installed to protect various parts of the plant, foam deluge systems that protect the refinery’s LPG tanks, pressure testing of hydrants across the site and ensuring that all extinguishers and hoses are in constant working order.
