Description
A collection of videos present in the UN Class 4 presentation
1. UN Class 4.1 Materials
A collection of 4.1 materials including magnesium fires, combustible dust fire and a case study for combustible dust at a sugar processing plant.
1.1. Magnesium burning in a Nitrogen atmosphere
Burning metals can be so aggressive that they can continue to burn under traditionally inert atmospheres like nitrogen and carbon dioxide. Here magnesium is the fuel and the oxidiser is Nitrogen.
1.2. Combustible Wood Dust explosion
1.3. Collapsing Corn Grain Silo catches fire
1.4. Imperial Sugar Explosion
Fire at Imperial sugar many years ago. This case study demonstrates the hazards associated with combustible dusts and the unlikely materials causing so much damage.
2. UN Class 4.2 Materials
A video of a UN Class 4.2 spontaneously combustible solids and liquids.
2.1. Diethyl Zinc - Highly dangerous
This video is part of series that Periodic Table of Videos conducted on Zinc. This is an incredibly pyrophoric and spontaneously combustible liquid.
3. UN Class 4.3 Dangerous when wet
A video demonstrating the enormous hazards a water reactive substance presents when in contact with water.
3.1. Rhubidium
Rhubidium is within group 1 of the periodic table and is an older brother to th elikes of lithium, sodium and potassium. The pink colour of the water is the result of a corrosive rhubidium hydroxide solution forming in the water. Remember, all directly water reactive materials and almost al UN Class 4 materials will have a corrosive run-off.
