DNV Manual N° 16B2 rev.0

Shelf life is a term used to describe the length of time over which a foam concentrate is stable and usable without a significant change in its performance characteristics. The shelf life depends essentially upon the composition, the ambient temperature range encountered, and the container materials of construction. A significant factor affecting foam shelf life is the ambient temperature range encountered. All our foam concentrates are listed by approval testing agencies such as Underwriters Laboratories, Inc. ,European Standard EN 1568 ,IMO standard…. Those listings also involve determining the usable temperature range for the concentrate. UNIVEX 3x6 Super is recommended for working within a range of : The normal usable temperature range for our SABO FOAM - UNIVEX is comprised within a maximum of +60°C (140°F) (Please check the Physical properties secti on on our data sheets). The usable/recommended temperature range is always stated on the labeling of the packaging in which the concen-trate is delivered out of the factory. Temperatures below the lower minimum usable temperature represent more of a problem than temperatures above the maximum usable temperature. Since in both cases one is dealing with a mixture of water and high boiling point solvents, going below the minimum usable temperature limit could result in freezing of the solution, which would pre-vent its use, for example in proportioning equipment. On the other hand, going above the maximum usable temperature, which should be avoided if possible, will not Impair the ability of the concentrate to be proportioned or the premixed solution to be discharged. However, it may result in a decrease in the performance characteristics of the concentrate or its dilute solution, when compared to the concentrate subjected to temperatures in the normal usable temperature range. Tests have been conducted with all our foam concentrates in intensive cycling of temperature variation without a significant decrease in performance. Going below the lower usable temperature will obviously result in freezing of the concentrate over a period of time. However, because of the composition the foam concentrates, placing the storage container in an area normally heated to ambient temperatures (15°C to 20°C (60 °F to 70 °F)), will render them to their original con dition with little or no change in performance characteristics. If the UNIVEX 3x6 Super concentrate is stored in accordance with our manufacturers recommendations, a shelf life because of the natural composition of the protein, shelf life of UNIVEX is generally given in excess of 10 years. It is generally advisable to inspect any equipment containing a Foam concentrate as per NFPA recommendation on an annual basis. Part of this inspection should include the foam concentrate agent itself. For foam used on board of vessels, please refer to the IMO standard requiring testing of the foam concentrate after three years from supply. It is always advisable to use original manufacturer laboratory to run the quality inspection test knowing all the particularities of its products.

1- Storage & Shelf life of foams agents

Minimum storage temperature (°C) - 12°C

Maximum storage temperature (°C) + 60°C

Pourpoint (°C) - 15°C

1. STORAGE IN ORIGINAL CONTAINERS As part of the listing or approval testing, the materials used in the packaging for our foam concentrates are also tested over the usable temperature range stated on them. SABO FOAM supplies its foaming liquid in different kind of containers (See our Bulletin for Packaging information). Steel containers case: 200 lt steel drums are supplied under specific request. Steel containers are made of painted mild steel; please periodically check the integrity of the containers, especially if stored outside. In the event of a heavy rusted container please proceed to change it. In the case of light rust on the drums, please re-paint them with appropriate paint. 2. STORAGE IN TANK Properly constructed large capacity tanks offer the optimum conditions for prolonged storage. As an integral part of a fixed systems or mounted on mobile equipment, foam liquid storage tanks provide immediate access to large volumes of foam liquid. A foam liquid storage tank, whether fixed or mobile, should be constructed with an expansion dome capacity of at least 2% of the tank volume. The tank should be closed to the atmosphere except for a pressure vacuum vent device mounted on the expansion dome. The foam liquid level in the tank should be maintained at a point half way into the expansion dome. In extremely corrosive environments, it may be desirable to fabricate these tanks in stainless steel or other suitable synthetic materials. The coating of storage tanks is not recommended for stainless steel tanks, but could be done for mild steel tanks to preserve the shelf life of the tank. Please make sure to follow the procedure of coating as described by the supplier recommendation. Any lesion in the surface of a coating due to incorrect painting application process will be penetrated by the foam liquid, lifting the coating away from the tank shell in sheets or flakes. Foam concentrates have good wetting characteristics, and if a crack in the coating develops, the foam concentrate will quickly go through the tank wall and the coating resulting in the coating failure, corrosion problems and probably tank failure. In addition, small particles of the coating may block the proportioners orifice during operation. 3. BASIC RULES The following points are some basic guidelines for optimizing foam liquid storage life and quality:

• Always keep the product in original containers supplied at the time of delivery. • Make sure the container or tank is kept sealed; in case of partial use of the quantity contained, close well

after use to prevent venting that may cause oxidation inside the container. • Keep foam tank filled up with liquid up to the expansion dome. • Filling up the topside of the tank with nitrogen in the event of a closed tank can avoid surface oxidation of the

product. • Storage tanks should be fitted with a pressure/vacuum-vent. That reduces condensation and evaporation

which is harmful to the foam liquid. This vent requires periodic inspection and cleaning. • Avoid direct exposure of tanks and drums to sun radiation and/or heat source. • Keep the product stored at temperature in the recommended range given on the technical data sheet. • Bladder tanks if properly maintained are considered as closed spaces therefore also offering best shelf life

for the foam concentrates. • Never mix different foam liquids in a common storage tank. • Avoid dilution of foam liquid with water or contamination with foreign ingredients, chemicals or oils. • Valves, couplings or piping that will be in continual contact with the foam liquid should not be constructed of

dissimilar metals. The use of different metals may cause electrolytic corrosion.

If changes in the quality of the concentrate occur, a sample of the concentrate in a clear/clean plastic bottle of 2 liter capacity should be sent to our quality department at: SABO FOAM s.p.a. Via Caravaggi 24040 - Levate - Italy.

Tests have been performed with our foam agents UNIVEX foam agents to determine compatibility with various foam system components. The recommendations contained in this bulletin are based upon both controlled test results and proven field applications. Only the most commonly used construction materials are addressed in this bulletin. Alter-native pipe, fittings, and valves may be used in some cases if acceptable to the customer and/or the authority having jurisdiction. Please consult SABO FOAM, for specific guidelines concerning any question of materials compatibility. 1. PROTEIN BASED FOAM CONCENTRATES Quality of our protein based foams generally have a very negligible effect on stainless steel materials. Corrosion could eventually be seen caused by the liquid pH variation during ageing conditions. 2. SYNTHETIC BASED FOAM CONCENTRATES Synthetic based foams have neutral pH and show the same corrosion index of fresh water on common metals . Moreover most synthetic foams have the benefit of preservative agents and corrosion inhibitors preventing problems of ageing and corrosion on tank (due to low chlorine content too). 3. RECOMMENDED MATERIALS: • Storage Tanks: Fiberglass – Isophthalic Polyester Resin, Epoxy Resin, or Vinylester Resin (Premium) Polyethylene – High density cross-linked polyethylene Stainless Steel – 304 and 316 Carbon Steel – Expansion dome required with concentrate filled to mid-point of dome (Interior coatings are not recommended due to surface activity of foam concentrates.) • Concentrate Piping: Teflon tape is recommended on all threaded fittings. Concentrates may dissolve some pipe joint compounds (pipe dope). Brass – Red brass, naval brass Stainless Steel – 304 and 316 Plastic – Fiberglass (green thread), PVC, CPVC Note: GALVANIZED PIPE AND FITTINGS MUST NOT BE USED IN CONTACT WITH UNDILUTED CONCEN-TRATE AS CORROSION WILL RESULT. • Gaskets: Butyl Rubber (BUNA-N), EPDM®, PTFE (Teflon®), Fluoro elastomer (Viton®), Blue-Gard Style 3000® • Painted Surfaces: Any foam concentrate spilled on painted surfaces should be flushed off with water immediately. The solvents in the concentrate may cause peeling or streaking of the paint.

3- Transportation & Transfer of foams agents

www.sabofoam.com

1. Road-tankers delivery recommendation: This delivery type is recommended for large volume and avoid packaging disposal but does re-quire some prior information and knowledge. Trucks and storage tanks containers including filling equipment i.e. pumps and hoses must be absolutely free from other materials to avoid any potential foam concentrate contamination. The transfer of foam between the Truck and the site storage tank has to be made gently, in order to avoid foaming of the liquid. It could be recommendable to fill intermediate containers to avoid foaming. During off-loading of the liquid please work with slow pressure (preferably < 1bar) and fill gently because foaming of the concentrate at the time of loading / unloading may prevent complete filling of the storage tank. Note: Connection point on the tank for transfer should be located on the bottom of the storage tank to avoid excessive foaming during filling operations. Aspiration point from the container, especially with protein foams, should be placed over the bottom of the tank to avoid potential sediments aspiration. Always contact us for more information and especially in case of specific connection requirement and hose length availability. 2. Pallets: Sabo Foam supplies its goods with two different kind of pallets : • CP3 (114x114 mm) four ways pallet The CP3 pallet could be filled with a maximum of 4x 200 lt drums (either steel or plastic) or 32 pieces of 25 and 20 lt cans (See Packaging Bulletin). • Euro (80x120 mm) four ways pallet The Euro pallet could be filled with a maximum of 2 x 200lt drums (either steel or plastic) and 26 pieces of 25 and 20 lt cans. For container shipping we recommend ordering complete pallets of drums or cans for better stabil-ity of the goods during transportation. 3. Foam transfer Pumps: The transfer of our foam agent from containers to the storage tank can be performed by using the following pumps : • Screw pumps • Centrifuge pumps • Rotodynamic pumps • Gear pumps. • Diaphragm pumps Note : Most types of pumps are able to move our products but it’s important to avoid air aspiration during filling operation to avoid cavitations of the pump and the formation of expanded foam.
