Whether acids, alkalis, toxic chemicals and/or flammable substances - when it comes to storing aggressive media, special stainless steel drip pans are often used. The requirements in the field of operational hazardous materials storage are very extensive and pose a challenge to every company with regard to the safe storage of aggressive liquids.
Stainless steel drip pans - ideal for drums, small containers and IBC containers
The material to be stored is the decisive factor in determining which material is used for storage. DIN 6601 specifies the tested media and describes the corresponding resistance under the respective material numbers. Furthermore, the corresponding sump tray should always be suitable for the respective storage containers, which is why, in addition to IBC s ump trays, we also offer pallet sump trays for both chemical pallets (CP1 to CP9) and Euro pallets (EUP) in our range. We also have drum trays for different sized drums. You will find small container collecting trays and laboratory trays for all types of small containers of different sizes.
The right size of sump tray
When storing hazardous substances, the legislator always requires the provision of a sufficient collection volume. This means that a collection tray must necessarily collect and retain the entire contents of the largest container to be stored (can, bottle, canister, barrel, IBC, KTC, etc.), or at least 10% of the quantity stored above the collection tray. If storage takes place within water protection areas, the requirements for the collection volume are even more stringent. Here, the entire quantity of the stored liquids must be retained in the collection tray.
Tasks of a collection tray
Our stainless steel drip pans are made of high-quality, resistant material and have a particularly stable and safe construction. Optionally, a drip tray canbe equipped with a grating . As a rule, a stainless steel drip tray has practical fork pockets for under-riding by means of a pallet truck, ant or forklift.
Attention: The containers or the pallets must not protrude over the edge of the collecting tray, otherwise leaking liquids cannot be collected in the collecting tray.
Stainless steel drip pans - conductive
Stainless steel drip trays are made of non-flammable, conductive material and are therefore particularly well suited for the safe storage of aggressive, flammable and combustible liquids in hazardous areas (Ex zones). We have perfected our stainless steel sumps with ground clearance (forklift pocket) for use in Ex zones and have integrated a fixed connection option for a customer-side equipotential bonding.
The big advantage: Equipotential bonding cables are mechanically firmly connected and cannot accidentally slip off and unintentionally interrupt the equipotential bonding, as is the case with a clamp connection, for example.
Proof of usability / documentation for sumps made of stainless steel
Stainless steel sumps up to a sump volume of 1000 l are subject to the StawaR (Steel Sump Directive), are regulated construction products and receive a manufacturer's declaration of conformity in the form of an Ü mark. Collecting trays made of stainless steel, which have a collecting volume greater than 1000 l or which do not comply with the StawaR for other reasons, require a DIBt approval or an approval in individual cases. This is granted by the lower water authority of the responsible district office. Our documentation for standard stainless steel collection trays consists of:
- Ü-sign or DIBt approval
- Tank test certificate
- Specialist company certificate according to WHG
- External monitoring by the TÜV
Steel sump guideline (StawaR) - a short explanation
The StawaR was included as a technical rule in the building rules list of the DIBt. Here is an excerpt of requirements from the StawaR for stainless steel collection trays with a collection volume of up to 1000 l:
- Height at least 50 mm and maximum 1000 mm
- Base area max. 10 m² (single tray)
- Maximum collection volume 1000 litres
- Freeboard at least 20 mm - with grating option, the freeboard must extend to the lower edge of the grating
- Material thickness according to DIN EN 10088-2 at least 2 mm
- Media resistant according to DIN 6601
- Welding seam test
- Marking with Ü-sign
Steel drip pans - a summary:
- tested, with Ü-mark or DIBt approval
- high mechanical resistance
- high chemical resistance
- robust, long service life
- for flammable substances
- attractive price
