The purpose of a bund provided for a tank or tanks is to contain any unintended escape of the material from those tanks. Bunds provide secondary containment for the liquids stored in the tanks or other items therein. The NIPLAST® range of containment bunds accord with HSE guidance and are sized to hold 110% of the tanks’ capacity.
When supplied with a NIPLAST® storage tank within our SAFEBULK ® OR SAFEWALL ® formats we extend the same corrosion resistance to the bunding mechanisms as the storage tanks, constructing to BS EN 12573 in either polypropylene or high density polyethylene.
Construction formats can be either cylindrical vertical or rectangular vertical and can be sized to accommodate one or more tanks or indeed other storage units such as IBCs.
Inclined rain skirts can be provided to prevent the ingress of water or bunds can remain open topped if located indoors. A thermoplastic NIPLAST® bund is often a cost-effective alternative to a civil built bund comprising brick, mortar and often a subsequent chemical liner. Leak detection and breach alarm options are available to alert operators to any early ingress of liquid. Bunds can incorporate side entry manways to ease access
A bund tank is there for safety. If your main tank is holding hazardous chemicals or materials and breaks then a bund is there to contain the spillages.
Usually, a bund will be constructed from a material that is resistant to the substances that it might come into contact with, such as chemicals, oils, fuels and other potentially hazardous materials. The bund is there to protect workers from a potential spill or leak, as well as protecting the environment surrounding the storage tank.
A containment bund is used as a safety measure. Unfortunately, every now and again a substance might leak or spill from the main containment system. This acts as a secondary barrier to contain what might be flammable or toxic liquids from spilling.
The bund capacity is designed to hold the entire contents of the original containment solution with a little extra room, ensuring that nothing spills in the event of a catastrophic tank failure.
Bund walls are constructed from materials that are resistant to whatever hazardous materials they might encounter. This means that the bund wall will not react with whatever substance the tank may contain. Our bund walls are made with corrosion resistant thermoplastics – primarily polypropylene and high-density polyethylene for high chemical resistance levels.
It is crucial that in the event of a spill the environment is protected. The damage that can be done if hazardous materials spill into soil, groundwater or surface water can be impossible to manage, so prevention is a must. Double skinned tanks mitigate the risk of environmental damage in the case of an incident and are often demanded by environmental regulations.
Typically, regulation and safety standards will require a bund with extra room to account for rainwater or fire fighting water. The cost of ignoring these regulations comes with fines, legal liability and damage to your reputation – and of course life could be threatened if the correct safety measures were not in place.
Proper access and drainage systems are also required for a tank bund. Access points allow for easy inspection and maintenance, while drainage systems help manage any liquids that accumulate within the bunded area. Drainage should direct collected liquids to designated storage or treatment areas, preventing further environmental impact.
It is incredibly important for bund tanks to be used in the chemical industry. When corrosive, toxic or flammable chemicals are involved then bunds must be placed around all chemical storage tanks to prevent the risk of a spill. Safeguarding in this way helps to maintain compliance with environmental regulations and ensures the safety of workers.
It is crucial that in the oil and gas industry, the risks of oil spills are mitigated. Containment bunds are used in various settings, such as primary containment tanks, pipes and processing plants. They are especially important around offshore drilling facilities where an oil spill can be harrowing to the environment.
Pesticides, herbicides, fertilisers and fuel can be incredibly detrimental to the environment if they spill. Therefore, dedicated containment bunds are essential in agriculture. These bunds are often found around storage tanks, pesticide mixing areas and storage facilities. They ensure that spills do not affect the environment and maintain crop and livestock health.
Chemical storage areas in water treatment plants will often use a containment bund. They are essential for containing the chemicals that are used in the process of water treatment. Using this helps to prevent the risk of accidental spills into water sources – protecting drinking water and aquatic life.
Facilities handling hazardous waste materials, such as waste storage sites and treatment plants, rely on dedicated containment bunds. They prove essential for preventing and containing any spills or leaks during waste processing, and ensuring safe disposal.
The use of Dedicated Containment Bunds offers several significant advantages:
Containment bunds are key when it comes to making sure that hazardous chemicals, materials and substances don’t make their way into the environment. Having this extra layer of protection means that soil and water are protected, and so too are the ecosystems, biodiversity and health of natural habitats. A dedicated containment bund can also work in conjunction with a secondary containment system.
In containing spills and leaks, employees, local communities and first responders are protected from potential exposure to hazardous substances. This minimises the health and safety risks associated with housing potentially harmful substances.
Many businesses will abide by strict environmental regulations that ensure that they are using secondary containment systems – in some cases this may even be a legal requirement. Dedicated containment bunds ensure compliance with these regulations.
