Spill Pallet
A spill pallet is a bunded secondary containment item that is designed to hold containers of oil, hazardous liquids, and fuels, typically in either a drum or in an intermediate bulk container. It is called a 'secondary containment item' because it is designed to catch the leaks and spill of the container's contents which rest upon it. The spill pallets can come in a variety of sizes to accommodate multiple containers. Several designs have been developed. UK legislation In the UK, a container of oil or fuel cannot be stored outside unless it is bundled in a secondary containment item (Oil Storage Regulations 2001). This means that if the container of oil leaks, it will be contained within the bund. The secondary containment item must be able to hold 110% of the largest container above. If a person were to store 4×200-litre drums on the sump pallet, the sump pallet must be able to hold of oil. Although there are no laws in the UK stating that a sump pallet must hold 110% of t ...

Bunding
Bunding, also called a bund wall, is a constructed retaining wall around storage "where potentially polluting substances are handled, processed or stored, for the purposes of containing any unintended escape of material from that area until such time as a remedial action can be taken."EPA Guidance Note on Storage and Transfer of Materials for Scheduled Activities page 7 Liquid containment The term can also refer to dikes, but it is frequently used to describe liquid containment facilities that prevent leaks and spillage from s and[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel
A fuel is any material that can be made to react with other substances so that it releases energy as thermal energy or to be used for work (physics), work. The concept was originally applied solely to those materials capable of releasing chemical energy but has since also been applied to other sources of heat energy, such as Nuclear power, nuclear energy (via nuclear fission and nuclear fusion). The heat energy released by reactions of fuels can be converted into mechanical energy via a heat engine. Other times, the heat itself is valued for warmth, cooking, or industrial processes, as well as the illumination that accompanies combustion. Fuels are also used in the Cell (biology), cells of organisms in a process known as cellular respiration, where organic molecules are oxidized to release usable energy. Hydrocarbons and related organic molecules are by far the most common source of fuel used by humans, but other substances, including radioactive metals, are also utilized. Fu ...

Drum (container)
A drum (also called a barrel) is a cylindrical shipping container used for shipping bulk cargo. Drums can be made of steel, dense paperboard (commonly called a fiber drum), or plastic, and are generally used for the transportation and storage of liquids and powders. Drums are often stackable, and have dimensions designed for efficient warehouse and logistics use. This type of packaging is frequently certified for transporting dangerous goods. Proper shipment requires the drum to comply with all applicable regulations. Steel drums Steel drums are ubiquitous industrial shipping containers. They are manufactured from sheets of cold rolled steel formed into a tube and welded along the side seam. Stainless steel, nickel, and special alloys are occasionally used. The bottom head is permanently attached by the manufacturer. Two primary options are available for the top head: * Open head drum, removable head drum: Top head is attached after filling with a closing ring and bolted lo ...

Intermediate Bulk Container
Intermediate bulk containers (also known as IBCs, IBC totes, or pallet tanks) are industrial-grade containers engineered for the mass handling, transport, and storage of liquids, partial solids, pastes, granular solids or other fluids. There are several types of IBCs with the two main categories being flexible IBCs and rigid IBCs. Many IBCs are reused with proper cleaning and reconditioning or repurposed. IBCs are roughly pallet-sized and either attach to a pallet or have integral pallet handling features. This type of packaging is frequently certified for transporting dangerous goods or hazardous materials. Proper shipment requires the IBC to comply with all applicable regulations. Types Rigid IBC Rigid intermediate bulk containers are a type of bulk box. They can be reusable, versatile containers with an integrated pallet base mount that provides forklift and pallet jack maneuverability. These containers can be made from metal, plastic, or a composite construction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stabilizers For Polymers
Polymer stabilizers (British English: polymer stabilisers) are chemical additives which may be added to polymeric materials to inhibit or retard their degradation. Mainly they protect plastic and rubber products against heat, oxidation, and UV light. The biggest quantity of stabilizers is used for polyvinyl chloride (PVC), as the production and processing of this type of plastic would not be possible without stabilizing chemicals. Common polymer degradation processes include oxidation, UV-damage, thermal degradation, ozonolysis, combinations thereof such as photo-oxidation, as well as reactions with catalyst residues, dyes, or impurities. All of these degrade the polymer at a chemical level, via chain scission, uncontrolled recombination and cross-linking, which adversely affects many key properties such as strength, malleability, appearance and colour. Stabilizers are used at all stages of the polymer life-cycle. They allow plastic items to be produced faster and with fewer defe ...

Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes and containers including bottles, cups, jars, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'' and many variations thereof. Its properties can be modified further by crosslinking or copolymerization. All forms are nontoxic as well as chemically resilient, contributing to polyethylene's popularity as a multi-use plastic. However, polyethylene's chemical resilience also makes it a long-lived and decomposition-resistant pollutant when disposed of improperly. Being a h ...

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galvanised
Galvanization ( also spelled galvanisation) is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten zinc. Protective action The zinc coating, when intact, prevents corrosive substances from reaching the underlying iron. It's main function is to act as a sacrificial anode to prevent the iron from rusting by cathodic protection. Zinc is more reactive than iron, so the zinc coating preferentially oxidizes to zinc carbonate, preventing the iron from corroding, even if there are gaps in the zinc coating. Additional electroplating such as a chromate conversion coating may be applied to provide further surface passivation to the substrate material. History and etymology The process is named after the Italian physician, physicist, biologist and philosopher Luigi Galvani (9 September 1737 – 4 December 1798). The earliest ...

Spill Containment
Spill containment is where spills of chemicals, oils, sewage etc. are contained within a barrier or drainage system rather than being absorption (chemistry), absorbed at the surface. One method is to use an inflatable stopper or pneumatic bladder which is inserted into the outflow of a drainage system to create a containment vessel. In the event of a spill the stopper bladder is inflated to block the drain/s and to prevent the spilled agent from entering the ground water, stream or river. The National Response Center (NRC) National Response Center. reports over 10,000 annual spills in the US from facilities. All of these can employ the spill containment measures mentioned above. Oil spills, when they occur, are detrimental to the surrounding environment, humans, and native wildlife. This type of spill is statistically rare, given how much oil is ...

Salvage Drum
A Salvage drum is an outer container used for shipping a leaking, damaged or non-compliant drum containing hazardous materials. Several designs are available. Originally designed to be greater than, or equal to, the construction and performance specifics of an inner container, the Performance Oriented Packaging Standards (POPS) of the US Department of Transportation requirement was that the Salvage Drum be at least a 'Z' (Packing Group III) solids container. Convinced that this was not an acceptable test for a Salvage Drum, on January 1, 1998, the 'T' Salvage Drum (1A2T) became the UN recommended salvage packaging for international shipments. The US-DOT, per 49 CFR 173.3, also recognizes the 'T' Salvage Drum for shipments within the US. Unlike the original 49 CFR Salvage Drum requirement, the 'T' Salvage Drum is most commonly an steel drum that, meets UN Model Regulations test requirement 6.1.5.1.11, which specifies that when filled with water, the drum can qualify for Packing G ...

Pollution Control Technologies
Pollution is the introduction of contaminants into the natural environment that cause harm. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have a human source, such as manufacturing, extractive industries, poor waste management, transportation or agriculture. Pollution is often classed as point source (coming from a highly concentrated specific site, such as a factory, mine, construction site), or nonpoint source pollution (coming from a widespread distributed sources, such as microplastics or agricultural runoff). Many sources of pollution were unregulated parts of industrialization during the 19th and 20th centuries until the emergence of environmental ...

Pallets
A pallet (also called a skid) is a flat transport structure, which supports goods in a stable fashion while being lifted by a forklift, a pallet jack, a front loader, a jacking device, or an erect crane. Many pallets can handle a load of . While most pallets are wooden, pallets can also be made of plastic, metal, paper, and recycled materials. A pallet is the structural foundation of a unit load, which allows handling and storage efficiencies. Goods in shipping containers are often placed on a pallet secured with strapping, stretch wrap or shrink wrap and shipped. In addition, pallet collars can be used to support and protect items shipped and stored on pallets. Containerization for transport has spurred the use of pallets because shipping containers have the smooth, level surfaces needed for easy pallet movement. Since its invention in the twentieth century, its use has dramatically supplanted older forms of crating like the wooden box and the wooden barrel, as ...
