1 CCAR HazmatU Surface Transportation of Automotive Hazardous Materials 1 Edition , April 2017 Copyright 2016, ShipMate , Inc., All Rights Reserved, Logos Used with Permission Hazmat Materials Training fact Sheet Module 2 Classification The classification of hazardous Materials is based on three key factors: Accident history Physical and chemical properties International hazard classification system Dangerous goods exhibit certain physical and chemical properties which may cause harm to humans, animals, or the environment. Materials can be hazardous in one or more of the following ways: Explosive Pressurized Corrosive Elevated temperature Flammable Radioactive Reactive Magnetized Toxic Explosive Materials may detonate or burn when exposed to heat or flame.

2 This would include hazardous Materials such as ammunition and fireworks. In addition, because they contain small explosive initiators and/or percussion caps, the following items would be included in this category as well: Air bag modules Seat-belt pretensioners Corrosive Materials like strong acids and bases can rapidly oxidize (burn) Materials , metals, paper, wood, and clothing. They can cause serious burns to skin or eyes. Some may react with other chemicals or Materials to release toxic or flammable vapors. Common examples include: Wet acid & wet alkaline batteries Concentrated cleaning compounds CCAR HazmatU Surface Transportation of Automotive Hazardous Materials 2 Edition , April 2017 Copyright 2016, ShipMate , Inc.

Common flammables include: Acetylene & propane Absorbent contaminated with fuel Gasoline & fuel additives Paint & paint thinners Solvents & cleaning compounds Adhesives & coating solutions Flammable Materials are substances that, when transported under forced heating, at or above their flashpoint, or substances transported at elevated temperatures ( , molten), can cause other combustible Materials to ignite through conduction (in contact with) or convection (radiation of heat).

4 Common examples include: Molten sulfur Molten aluminum Bituminous asphalt Reactive Materials are those substances that may chemically mix with air, water, or other substances to cause exothermic (liberate heat) reactions. Many produce oxygen and will burn quickly. In addition, many do not have to be near heat or flames to ignite they can burn spontaneously. Many also generate toxic and flammable vapors as well. Common reactive Materials include: Benzoyl Peroxide ( , epoxy cream hardener) Hypochlorite solutions ( , bleach) Cleaning compounds Radioactive Materials are substances undergoing rapid electrical and subatomic transformations, thus exhibiting radioactivity (a spontaneous discharge of energy).

5 This energy may cause our cells to become genetically altered. Radioactive Materials can include: X-ray equipment Smoke detectors CCAR HazmatU Surface Transportation of Automotive Hazardous Materials 3 Edition , April 2017 Copyright 2016, ShipMate , Inc., All Rights Reserved, Logos Used with Permission Hazmat Materials Training fact Sheet Module 2 Classification Toxic Materials are substances that, if allowed to enter the body through the nose, mouth, or skin, can make you sick or even cause death. Fumes, dust, and vapors from toxic Materials can be especially harmful because they can be inhaled and pass quickly through the lungs into the blood, allowing the poisons to circulate throughout the body.

6 Common toxic Materials include: Pesticides Chlorinated solvents ( , parts wash solution) Fumigants Pressurized Materials that are contained under extreme pressure are particularly dangerous because the energy is stored within a confined volume which could be released instantly if the cylinder or fittings fail or rupture. In some cases, the gaseous Materials may also be extremely cold because they are cryogenic (refrigerated) gases. Common examples include: Accumulators ( , shocks, struts) Acetylene & argon Fire extinguishers Refrigerants Tire inflators Certain air bag modules ( , air curtains) Aerosols Magnetized Materials are regulated for air transport when shipped in large quantities only because the magnetic field induced by the articles may affect the aircraft's navigational instruments.

7 Therefore, magnetized Materials are required to be stowed on aircraft in specially designed compartments, or fitted with Faraday shielding, to reduce the magnetic interference. Common magnetized material include: Speakers Magnetic clutches Magnetic switches CCAR HazmatU Surface Transportation of Automotive Hazardous Materials 4 Edition , April 2017 Copyright 2016, ShipMate , Inc., All Rights Reserved, Logos Used with Permission Hazmat Materials Training fact Sheet Module 2 Classification International standards have been established by the UN Committee of Experts on the Transport of Dangerous Goods. They have assigned hazardous Materials into one of nine internationally recognized and adopted hazard classes, including: Class 1 - explosives Class 2 - gases Class 3 - flammable liquids Class 4 - flammable solids & pyrophoric liquids Class 5 - oxidizers & organic peroxides Class 6 - toxic Materials Class 7 - radioactive Materials Class 8 - corrosive Materials Class 9 - miscellaneous dangerous goods, substances, & articles Class 1 hazardous Materials are explosive substances.

8 There are six divisions of explosives, including: Division - mass explosion ( TNT, dynamite) Division - projection hazard ( , missiles, grenades) Division - fire hazard ( , flares, fireworks) Division - no significant blast ( , air bags, small arms cartridges) Division - very insensitive ( , blasting agents, ammonium nitrate) Division - extremely insensitive ( , squibs) Class 2 is comprised of compressed, liquefied, and cryogenic (refrigerated) gases and gases in solution. This class also includes articles containing substances of Class 2 such as shock absorbers, brake boosters, and hood stays. There are three divisions of Class 2 gases: Class - flammable gases ( , propane, acetylene) Class - non-flammable gases ( , fire extinguishers, refrigerants) Class - toxic gases ( , fumigants, carbon monoxide) CCAR HazmatU Surface Transportation of Automotive Hazardous Materials 5 Edition , April 2017 Copyright 2016, ShipMate , Inc.

9 , All Rights Reserved, Logos Used with Permission Hazmat Materials Training fact Sheet Module 2 Classification Class 3 substances are comprised of: Flammable liquids Liquid desensitized explosives Flammable liquids are further defined as liquids, mixtures of liquids, or liquids containing solids in solution or suspension ( , paints, lacquers) that emit flammable vapors and which have a flashpoint (temperature at which the vapor-air mixture can ignite) of 60 C (140 F), as determined by a closed-cup flammability testing apparatus. Common flammable liquids include gasoline, fuel additives, paint, adhesives, coating solutions, solvents, and alcohols. Class 4 includes substances and articles, other than those classified as explosives, which are readily combustible, self-reactive, or which may cause or contribute to a fire.

10 Class 4 is divided into three divisions: Class - flammable solids Class - substances liable to spontaneous combustion Class - substances that, in contact with water, emit flammable or toxic gas Class 5 is divided into two divisions: Class - oxidizing substances Class - organic peroxides Class oxidizers are substances that may yield oxygen which causes, or may contribute to, the combustion of the substance or other Materials . A common example of an oxidizer is 8 percent or greater concentrations of hydrogen peroxide. Class organic peroxides are derivatives of hydrogen peroxide with a special chemical structure which may be thermally and chemically unstable.
