Sprinkler protection system for hazardous goods warehousing facilities

Minimax presents new fire protection solution LiquidProtect

Minimax has received approval from the German Association of Property Insurers (VdS) for their innovative fire protection solution, which protects hazardous goods warehouses by means of a sprinkler system using a foam agent. This concept combines high safety for people and the environment with a very fast, effective and localized firefighting. Moreover, the system helps to minimize operational downtimes in the event of fire, and there are very few construction requirements. It can be used in warehouses with large containers such as IBC and warehouses with narrow aisles.

The concept is based on several modules interacting with each other. In the event of a fire, spilling fluid is deliberately directed to the rack aisles with the help of sloped rack stands and baffles installed in the racks. So-called fuel stops are embedded in the floor at regular intervals along the aisles, which collect the flammable fluid, preventing it from spreading along the aisles. Special sprinklers are placed near the fuel stops, ensuring early release and targeted distribution of the water-foam mixture into the aisles. Additional quick-release sprinklers distribute water and a special foam agent into the racks. This concept enables rapid, effective and localized firefighting, helping to keep fire damage and operational downtimes to a minimum.

High personal safety and environmental protection
This fire protection system does not involve complete flooding of the protected room with firefighting agent. Consequently, it offers a higher degree of safety compared to agents hazardous to humans, such as high expansion foam or CO2. With the sprinkler solution there is also less danger of firefighting agent spreading to lower levels or neighboring areas. The early and localized firefighting, combined with fairly small amounts of water-foam used to fight the fire contribute to a better environmental footprint.  

Very fast and effective firefighting
The sprinklers are arranged at close intervals, both in the racks and in the aisles, facilitating early fire detection and immediate firefighting without any pre-warning period. Together with the fuel stops and the use of a special foam agent, fast, raging fires can be fought effectively – which is essential in case of flammable liquids spilling from large bulk containers.

Minimal operational downtimes in the event of fire
Only the sprinklers in the affected area release and the fire is rapidly fought resulting in little primary and secondary damage. This includes thermal stressing of the building and rack structures, corrosion or short circuits due to the flooding of technical installations (control panels, ventilation systems, conveying equipment). The subsequent removal of the firefighting agent is also far easier than in a building completely flooded with high expansion foam.

Marcel Ruesink from Minimax answered the question how to mitigate fire events for LNG facilities at the LNG congress in Barcelona

International LNG congress in Barcelona

Marcel Ruesink from Minimax answered the question how to mitigate fire events for LNG facilities at the LNG congress in Barcelona on 16-17 October 2017.

LNG facilities are exposed to fire risks. When a fire occurs due to failing equipment or inadequate  fire control and protection measures, extended business disruptions may be the consequence. These will cause substantial costs and, at worst, may cause customers to turn to new suppliers elsewhere, if the delivery delays continue. The consequences originates due to the nature of LNG processing, the potential disperse of vaporized natural gas with its high fire load and rapid fire spread. The risk can be reduced by detection, fire control and/or extinguishing systems.

LNG fire has challenging facets. Minimax has the right fire control and protection solution for the various LNG facilities. Recommended fire control and protection applications which suit the requirements of LNG facilities are for example vaporization reduction with Hi-Ex foam, gas cloud dispersion control by water curtains, fire suppression with dry chemical and suppression system with inert gas systems for fire risks in enclosures like compressors and plant utilities.

Minimax understands the safety management issues at LNG operations and has in-depth know-how of codes and standards for fire protection, like IMO IGC (81/224), NFPA, EN & BS (66/224). Additionally Minimax has the ability to adopt local requirements, great track record on successful project completion and a company culture to meet expectations of global acting companies.

Minimax provides tailored solutions wherever there is a fire threat and has a widespread fire protection experience on industrial applications, including LNG facilities, jetties, loading manifolds, compressors, machinery rooms, steam and gas turbine driven power plants. So Minimax has the competence on both landbase and marine projects and the experience to integrate them.
