GUIDE TO USING A CHEMICAL SPILL RESPONSE KIT

Posted on by Haianh

A. What to do after purchasing a chemical spill response kit

Preparing action plans and backup materials for oil and chemical spills in industrial settings is crucial. It is essential to ensure workplace safety and protect the environment for your business. Once you have spill response kits, you need to understand how to use them effectively to manage spills efficiently.

First, anticipate areas where chemical spills or leaks might occur. Ensure the spill response kit is stored near these areas, where it is easily visible and accessible in case of an emergency.

Next, open the chemical spill response kit and familiarize yourself with the products and instructions included. Typically, a chemical spill response kit contains:

  • Absorbents in bagged form
  • Chemical absorbent booms
  • Absorbent pillows and pads
  • Personal protective equipment (gloves, safety glasses, etc.)
  • Shovels, brooms, and waste bags
  • Hazardous waste labels
  • Instruction cards, warning barricades, etc.

(The included products may vary depending on the kit’s capacity and customer requirements.)

B. Basic chemical spill response instructions

1. Protect the spill area

First, create a barrier around the outside of the spill area using absorbent booms or absorbent pillows. This will isolate the spill location, reduce spreading, and minimize the impact on the environment and people nearby. The booms and pillows will both contain and absorb the spilled chemicals.

For spills on water, use oil absorbent booms to create a barrier preventing the spill from spreading and affecting the environment. Multiple layers of booms can be used to form an effective barrier depending on the terrain and severity of the spill.

2. Stop the source

When a chemical spill occurs, first stop the source (close valves or taps, upright overturned containers, contain the spill source, etc.). Stopping the source will reduce the impact and scale of the spill, providing a safer working environment for the responders and allowing for quicker, more effective action.

3. Clean up the chemicals

Use appropriate absorbents from the kit (chemical absorbent pads, oil absorbent pads, oil absorbent cotton, chemical absorbent pillows, cleaning powder, etc.) to absorb the spilled liquid. Use chemical/oil absorbent pads to quickly absorb, cover maximum spill area, and collect any residue left on the surface. Use pillows to absorb larger volumes of liquid.

Cleaning powder helps absorb large quantities of liquid and is excellent for removing spills in cracks and crevices on uneven surfaces. Especially when using absorbent powder:

  • Sprinkle the absorbent powder from the bag onto the surface of the spilled liquid. Sprinkle from a low and close distance to avoid dust and product waste.
  • After a few minutes, the powder will absorb and encapsulate the spilled liquid or neutralize acids.
  • Use a stiff broom to sweep back and forth until the surface is dry and clean. Typically, 1 kg of absorbent can absorb 4 liters of oil. If there are still oil traces on the surface, it means the absorbent is oversaturated. Additional absorbent is needed.

4. Handle used products

Collect solid waste (booms, pads, pillows, absorbent powder soaked with spilled liquid) using a shovel and gloves into a container or bag, then dispose of it according to local Environmental Protection Agency regulations. The appropriate waste handling method should be applied depending on the type of chemicals absorbed. Remember to label hazardous waste bags properly.

Graphene-based hybrid material enables efficient light conversion of invisible light

Posted on by Haianh

Researchers from various institutes in Barcelona and Germany have demonstrated that a hybrid material consisting of a monolayer of graphene and a metallic grating structure is an excellent candidate for relevant commercial applications in which efficient nonlinear conversion of (invisible) terahertz light is required. This work has just been published in ACSNano, in a paper with Dr Klaas-Jan Tielrooij, leader of the ICN2 Ultrafast Dynamics in Nanoscale Systems group, as last author. Metal grating combined with graphene opens up the road to terahertz nonlinear photonic applications.

Nonlinear optical conversion – i.e. the process by which an incident light beam of a certain wavelength turns into rays of different wavelengths, due to its interaction with the material it passes through – is relevant to for many current and future technologies, such as imaging, information storage and processing, telecommunication, quantum technologies, and other fields.

The ideal material for these applications should provide, first of all, a very high conversion efficiency, which means that a significant fraction of the incoming beam has to be converted into light of the desired wavelengths. It is also required to have a small footprint (that is, as little material as possible has to be used); to be compatible with standard CMOS technology used in most electronic devices; and to be able to operate at room temperature. Particularly needed is an optimal solution for applications in which the incident light is in the terahertz (THz) region of the electromagnetic spectrum. This light cannot be seen by the human eye, yet it is commonly used for applications ranging from airport security to product inspection, and can play an important role in future communication technologies.

Two-dimensional materials are highly interesting for light conversion. They consist of a single layer (or a couple of them) of atoms and thus have almost zero-thickness (this is why they are called 2D materials). This characteristic ensures a small material footprint. In addition, since they are thinner than the wavelength of light, the optical waves propagating in these materials remain in phase. Among them, graphene, a by-now-well-known material made of a monolayer of carbon atoms arranged in a honeycomb structure, is particularly promising. This is because it exhibits very large nonlinear conversion coefficients, especially in the THz range. On the other hand, though, its extremely reduced thickness affects its conversion efficiency, due to the small quantity of matter the light can interact with. To overcome this problem, the authors decided to combine graphene with another material system that enhances this interaction.

A team of researchers from the Catalan Institute of Nanoscience and Nanotechnology (ICN2, Spain), the Helmholtz-Zentrum Dresden-Rossendorf (HZDR, Germany), the Institute of Photonic Sciences (ICFO, Spain), the Max Planck Institute of Polymer Research, Mainz (Germany), the University of Bielefeld (Germany) and the Technical University of Berlin (TUB, Germany) have combined graphene with a metallic structure that provides field-enhancement, leading to a hybrid material characterized by very high nonlinear light conversion efficiency. As explained in a scientific article recently published in ACSNano, this structure (grating-graphene) produces outcoming light at the new wavelength having an intensity more than 1000 times higher than the one obtained using just graphene.

Dr Klaas-Jan Tielrooij, leader of the ICN2 Ultrafast Dynamics in Nanoscale Systems group and last author of the paper explains: “The combination of graphene and a metal grating leads to highly efficient conversion of terahertz light, reaching up to 1% (in field) for rather weak incident light.” Dr Jan-Christoph Deinert, from HZDR, first author of the work, adds: “This hybrid material made it possible for us to observe light that oscillates three times, five times, seven times, and even nine times faster than the incoming light.”

The outstanding conversion efficiency of this hybrid material guarantees low power consumption in the conversion process, while the compatibility of graphene with CMOS technology allows for integration in devices based on such technology. Overall, this grating-graphene structure presents itself as an excellent candidate for commercially viable applications requiring nonlinear conversion in the terahertz regime, chip-integration, room temperature operation and low power consumption.

Choose the right product for your needs based on color

Posted on by Haianh

Industrial enterprises must be well-informed about industrial cleaning products and spill response solutions to promptly handle potential hazards to humans and the environment. One of the most significant concerns is dealing with oil and chemical spills during operations.

Using rags and scrap fabric is neither effective for thoroughly cleaning oil stains nor reusable for the spilled liquids. Instead, the market offers specialized oil absorbent materials that improve efficiency, save time, and reduce costs for handling oil and chemical spills.

Preventing and addressing issues caused by oil/chemical spills according to government regulations and laws helps ensure worker safety and environmental protection, while also avoiding hefty fines for violations.

Globally, specialized oil absorbent products use different colors to indicate their applications. Let’s explore the differences between these colors and the functions of these products with BIGNANOTECH.

1. Gray, Blue, and Yellow: Neutral Absorbents/Universal Absorbents

Products in these colors are typically used for responding to and handling chemical-related incidents involving corrosive and highly volatile liquids. These chemicals are commonly used in modern industrial fields but are particularly hazardous in case of leaks or spills.

Strong solvents, coolants, and non-concentrated chemicals are effectively cleaned and contained by chemical absorbent pads in these colors, preventing further spills. These hazardous materials must be stored in specialized containers.

It is important to note that these products do not neutralize the chemicals they absorb and clean, so they remain dangerous if misused. Therefore, users must be equipped with appropriate safety gear when handling spills.

2. White, Brown: Oil Absorbents

These color-coded products, such as pads and booms, are used to absorb and clean up oil spills, especially useful for dealing with water or other liquids contaminated with oil. These products are made from hydrophobic materials or treated with hydrophobic chemicals, so they only absorb oil and completely repel water. Additionally, nano technology enhances their oil absorption capacity without releasing the absorbed oil.

White oil absorbent pads and booms, being hydrophobic, float on water to absorb and contain spilled oil, making them ideal for use in rivers, lakes, seas, wells, and tanks. Oil stains are easily visible on white products. Brown products, while less visible when soaked with oil, do not compromise on absorbency. The market primarily uses white oil absorbent pads, booms, and pillows for any industrial oil cleaning activities.

   

3. Pink: Hazardous Material Absorbents
For highly dangerous liquids and chemicals, pink absorbent products are typically used. These products are specially designed to absorb even the most toxic chemicals without degrading or reacting with the chemicals. It is crucial to wear protective gear and handle these chemicals with extreme care.

Where to Buy These Products?

There are many suppliers of these products in the market. However, some products lack clear origins and guaranteed quality. Some products are imported from major global brands like 3M and Spilfyter. These products ensure quality but come at a high cost due to additional taxes when imported to Vietnam.

Understanding these challenges, BIGNANOTECH, a leading manufacturer of industrial oil and chemical spill response products in Vietnam, has introduced N-FIBER, H-FIBER, and G-FIBER product lines. These lines provide high-quality products at reasonable prices. Produced with advanced nano technology exclusively from Japan, BIGNANOTECH is confident in satisfying customers, helping to clean the environment, and ensuring a safe and clean working environment.

How to Handle Oil Spills on Water?

Posted on by Haianh

What is an oil spill? Basic steps to handle oil spills on water.

1. What is an Oil Spill?

An oil spill refers to an accident that occurs during the extraction, production, processing, or transportation of petroleum and petroleum-based products (such as pipeline leaks, ship accidents, rig incidents, etc.), leading to oil escaping into the environment, causing water pollution and adverse impacts on ecosystems. These incidents require swift and thorough response. An oil spill is typically defined as a release of several hundred liters or more of oil into the environment.

Oil spills in Vietnam

According to sources from the Ho Chi Minh City Department of Natural Resources and Environment, Vietnam records approximately 10 significant oil spills per year over the past 20 years. These incidents negatively affect the human environment and severely impact ecosystems. Therefore, addressing the consequences of oil spills is crucial for protecting our environment.

Negative effects of oil spills

Industrial oil spills can spread in different environments, posing serious threats to microorganisms in those areas, especially in water environments, where oil easily disperses and spreads. A concentrated oil spill can immediately cause mass fish deaths or poisoning. However, the long-term effects of oil spills on ecosystems can be even more severe and lasting.

Oil pollution contaminates organic matter in rivers, lakes, and seas, reducing food sources, and ultimately limiting the reproductive capacity of aquatic life and humans.

2. How to Handle an Oil Spill

Due to the physical properties of oil, it floats on the surface of water when spilled. The first step in addressing an oil spill is to isolate the spill area, followed by subsequent response steps.

Below are some common methods for dealing with oil spills on water:

  • Using Oil Containment Booms: This method isolates the spill area to prevent oil from spreading further across the water’s surface.
  • Using Oil Absorbent Products: Specialized products such as oil-absorbent pads, pillows, and polypropylene-based fibers can be used to absorb and recover oil from the water surface.
  • Burning Oil on Site: As an emergency measure, burning oil at the spill site can be used. This must be done quickly to prevent oil from spreading further. However, this method can produce air pollutants and affect the ocean and marine life.
  • Using Oil Dispersants: Natural water disturbances can disperse oil, but the process is slow. To speed up dispersion, chemical oil dispersants can be used. These chemicals are added to oil to facilitate dispersion and reduce formation.
  • Using Basic Tools: In coastal areas, local communities can engage in oil spill clean-up using simple tools such as rakes, shovels, buckets, and vacuums. This method is suitable for small-scale oil spills.

 

Containment is the most critical step in oil spill response. By isolating the affected area, further spreading is prevented, allowing for easier management and response. Oil containment booms not only contain the oil but also have high absorbency, allowing simultaneous containment and absorption, which can help to shrink the spill area. If the spill area is large, multiple booms can be connected to increase the containment radius.

Additionally, specialized products such as oil-absorbent pads, pillows, and fibers must be prepared in advance to ensure a quick response when oil spills occur. These products only absorb oil, not water, and can float on the water surface regardless of waves or wind, making them ideal for handling oil spills on water.

3. Where to Buy These Products?

BIGNANOTECH is a leading company specializing in the production and distribution of oil spill response products, including oil-absorbent booms, pads, pillows, fibers, and other products designed to tackle oil spills.
