My kid is such as smart guy but he struggles to sit still and complete assessment tasks. I knew that I needed to learn more about how to get people with sensory processing disabilities to learn effectively. It turns out that by using some of the latest teaching techniques and some additional teaching resources such as wiggle chairs and fiddle balls which can help kids to focus. My son has had such great results with a different style of teaching which is why I wanted t start this blog. It should be useful for parents and teachers of kids with sensory processing issues.
Oxidising substances fall within the nine classes of dangerous goods transported all over the world. They are categorised as substances that can cause or speed up the combustion of the materials around them. The chemistry involved happens through a redox reaction. In the event of a fire, the oxidising agent gives off oxygen that encourages the other materials around them to burn. To add on that, oxidisers also exude heat and worsen the effects of the fire. Here is a look at some oxidisers commonly transported in the freight industry.
Ammonium Nitrate Fertilisers
Ammonium nitrate is needed for supplying nitrogen to crops in farms. It enhances the overall health of plants by making them green and leafy. The substance comes as a colourless, odourless crystal salt created by combining nitric acid and ammonia gas. The resulting chemical compound is capable of burning and producing lots of heat that speed up the combustion of other materials around it. It is also important to note that ammonium nitrate does not leave any residue upon combustion. Certainly, fertiliser is in high demand across the globe and ammonium nitrate is a substance you might encounter quite often in the transport world.
Chemical Oxygen Generators
Chemical oxygen generators are devices used to generate and release oxygen through a chemical reaction. The oxygen is derived from inorganic super oxides, ozonides, chlorates and perchlorates. By generating oxygen, these generators certainly elevate the risk of a fire spreading from one point to another since oxygen is one of the primary requirements for combustion to take place.
You should expect chemical oxygen generators in aircrafts, breathing devices for firefighters, submarines and many other places.
Ammonium dichromate
Ammonium dichromate is another oxidising agent that qualifies as a dangerous good. The compound contains ammonium and chromium ions. The chromium ions are in their oxidation state, meaning that they can readily give off oxygen when the substance is involved in a host of chemical reactions. Basically, ammonium dichromate exists as orange, acidic particles that dissolve readily in alcohol and water at room pressure and temperature. Some of the common materials that contain this chemical are dyeing pigments and tanned leather. Additionally, you should note that ammonium dichromate is very toxic and carcinogenic because of the presence of chromium VI (six) compounds.
Take note of all these substances and ensure that you minimise the risks involved by notifying relevant authorities or availing appropriate fire safety equipment and fire retardants. Due to the lack of knowledge on the dangers they pose, some workplaces and freight firms may not take the necessary safety measures required.
