TRANSPORT DANGEROUS GOODS BY AIR LECTURE 4: CLASS 5-CLASS 8
DANGEROUS GOODS CLASSES • Class 1 - Explosives • Class 2 - Gases • Class 3 - Flammable liquids • Class 4 - Flammable solids and reactive substance • Class 5 - OXIDIZERS AND ORGANIC PEROXIDES • Class 6 - TOXIC AND INFECTIOUS SUBSTANCES • Class 7 - RADIOACTIVE MATERIAL • Class 8 - CORROSIVE ARTICLES AND SUBSTANCES • Class 9 - MISCELLANEOUS ARTICLES AND SUBSTANCES AMC - TDG 2103 BY SIR ARIFF
CLASS 5 : OXIDIZERS & ORGANIC PEROXIDES 5.1 Oxidizers 5.2 Organic Peroxides Oxidizing Agent
OXIDIZING AGENT Chemical Compound that readily transfer oxygen atoms Not necessarily Combustible Produce oxygen on its own upon temperature rise and heat when in contact with organic compound.
5.1 OXIDIZERS • Also known as: • Oxidant • Oxidizing Agent All oxidizing agent other than organic peroxides. It can be divided into 4 categories Class 1 Class 2 • Examples: • Calcium Hypochloride • Ammonium Nitrate • Potassium Permanganate Class 3 Class 4
5.1 ORGANIC COMPOUND Oxidizing agent either in liquid / solid form Example Intentionally or unintentionally initiate explosive • Benzoyl Peroxides • CumeneHydroperoxide • Hydrogen Peroxide Have different chemical structure
Potential Risks . . . • Oxygen is needed in combustion. • As the chemical capable to produce its • own oxygen, it has tendency to • promote fire with help of ignition • source. Promote Fire Sensitive to heat & friction • Temperature influence chemical • compound to produce oxygen. • Friction cause temperature rise Burn Rapidly • As chemical burn, temperature rise • More oxygen produce • Fire burns rapidly.
Potential Risks . . . • Oxygen is needed in combustion. • As the chemical capable to produce its • own oxygen, it has tendency to • promote fire with help of ignition • source. Ignite easily Explosion • Temperature influence chemical • compound to produce oxygen. • Friction cause temperature rise
Potential Risks . . . Sensitive to light • Refer to organic compound • Must be stored in darkness • Present of light causes the changes in • chemical properties. Release gas at room temperature • Some chemical compose oxygen at • room temperature. • Must be stored refrigerated
CLASS 6 : TOXIC & INFECTIOUS SUBSTANCE 6.1 Toxic Substance (Poison) 6.2 Infectious Substance (Biohazard) Substance that liable to cause death/serious injury to human health if inhaled/ swallow or by skip absorption. Substance contain virus culture, PATHOGEN, used intravenous needles.
Virus & Disease Poisonous Potential Risk Infection Death
CLASS 7 : Radioactive Substance • Substances used in Medical / Scientific purposes • Comprises substance or combination of substance • emit radiation. • This radiation cause severe or fatal health • problems to people who are exposed to. Nuclear Uranium Plutonium Examples
Harmful to people Affect human body health Hair Brain Thyroid Blood system Heart Gastrointestinal Tract Reproductive Tract Potential Risk Can affect genetic
Substance in the event of leakage, can cause severe damage by chemical action when in contact with living tissue or can materially damage other freight or the means of transport. CLASS 8 : Corrosives 8.1 Acids 8.2 Alkali
Potential Risk . . . • Produce heat and gases. • Destroy living tissue and other materials • Can produce damage to aircraft structure
