5.7.1 Characteristics of Class 9 substances
Explain: That some substances or articles do not have the characteristics which require inclusion in Classes 1 to 8 but may yet have the potential to present some hazard to people or the environment during carriage.
State: That in the UN classification system, Class 9 is provided for miscellaneous substances and articles. (See Note B 1).

2. Class 9 5.7 Danger label 5.7.2 Danger labels, marking and placards
Display: The Class 9 danger placard

3. Examples 5.7 Asbestos Lithium batteries
Polychlorinated biphenyls (PCBs)
Polymeric beads & plastic moulding compounds
Life-saving appliances
Substances carried at elevated temperatures
5.7.3 Principle examples of substances and articles
Discuss: Examples of substances & articles in Class 9:
ASBESTOS - does not meet the criteria for toxicity in Class 6.1 but inhaling the fibres can cause asbestosis, a debilitating and potentially fatal illness.
LITHIUM BATTERIES - multiple hazards, particularly if the batteries are ruptured or involved in a fire. Risk of fire or explosion. Reaction with water can produce hydrogen (flammable gas). Solid materials can cause severe damage to the eyes, skin. Some battery components are also toxic or irritant. (See Note B 2). Lithium batteries and equipment containing them must be protected from accidental operation, shorting or damage caused by movement during carriage.
POLYCHLORINATED BIPHENYLS (PCBs) - coloured synthetic liquids found in transformers and other such electrical equipment. If spilled, persist in the environment where they could cause long-term damage. Decompose in fire to give toxic fumes.
POLYMERIC BEADS & PLASTIC MOULDING COMPOUNDS, EXPANDABLE, EVOLVING FLAMMABLE VAPOUR – e.g. polystyrene. Toxic fumes produced in fire. Danger from explosive vapour-air mixture after heating.
LIFE-SAVING APPLIANCES – a hazard if self-inflating device is activated accidentally. Can also contain other dangerous goods as equipment – small explosive charges, compressed gases, flammable and corrosive substances. But some airbag inflators are in Class 2.
SUBSTANCES CARRIED AT ELEVATED TEMPERATURES – solids at more than 240ºC, and liquids at more than 100ºC, but below their flashpoint, and only if they do not have hazards falling in Classes 1 to 8.
Recall: The Red and White “thermometer” sign which must be displayed on the vehicle.

4. Environmentally Hazardous Substances 5.7
Solids and liquids pollutant to the aquatic environment
Environmentally hazardous substance mark
Genetically modified organisms other than those of class 6.2
5.7.4 Environmentally hazardous substances
Explain: Environmentally hazardous substances include, among other things, liquid or solid substances pollutant to the aquatic environment and solutions and mixtures of such substances (such as preparations and wastes).
UN No ENVIRONMENTALLY HAZARDOUS SUBSTANCE, SOLID, N.O.S. or
UN No ENVIRONMENTALLY HAZARDOUS SUBSTANCE, LIQUID, N.O.S.
They shall be assigned to packing group III.
State: Packagings of un 3077 and un 3082 require the environmentally hazardous substance mark in addition to the class 9 placard.
Explain: Genetically modified microorganisms (GMMOs) and genetically modified organisms (GMOs) are microorganisms and organisms in which genetic material has been purposely altered through genetic engineering in a way that does not occur naturally. They are assigned to Class 9 (UN No. 3245) if they do not meet the definition of infectious substances, but are capable of altering animals, plants or microbiological substances in a way not normally the result of natural reproduction.

5. Segregation 5.7 Segregate from foodstuffs- Asbestos PCBs
Genetically modified organisms
5.7.5 Segregation
State: Packages as well as uncleaned empty packagings, including large packagings and intermediate bulk containers (IBCs), of UN Nos. 2212, 2315, 2590, 3151, 3152 or 3245, shall not be stacked on or loaded in immediate proximity to packages known to contain foodstuffs, other articles of consumption or animal feeds in vehicles, in containers and at places of loading, unloading or transhipment.
UN BLUE ASBESTOS (crocidolite) or BROWN ASBESTOS (amosite, mysorite)
UN 2315 POLYCHLORINATED BIPHENYLS, LIQUID
UN 2590 WHITE ASBESTOS (chrysotile, actinolite, anthophyllite, tremolite)
UN 3151 POLYHALOGENATED BIPHENYLS, LIQUID or POLYHALOGENATED TERPHENYLS, LIQUID
UN 3152 POLYHALOGENATED BIPHENYLS, SOLID or POLYHALOGENATED TERPHENYLS, SOLID
UN 3245 GENETICALLY MODIFIED MICROORGANISMS or GENETICALLY MODIFIED ORGANISMS
Expalin: When these packages are loaded in immediate proximity of packages known to contain foodstuffs, other articles of consumption or animal feeds, they shall be kept apart from the latter:
(a) By complete partitions which should be as high as the packages bearing the said labels;
(b) By packages not bearing labels conforming to models Nos. 6.1, 6.2 or 9 or packages bearing labels conforming to model No.9 but not containing goods of UN Nos. 2212, 2315, 2590, 3151, 3152 or 3245; or
(c) By a space of at least 0.8 m;
unless the packages are provided with an additional packaging or are completely covered (e.g. by a sheeting, a fibreboard cover or other measures).

6. Spillage 5.7 Package labels Safety data sheets Contain
5.7.6 Containment and actions on exposure
State: That as the instructions in writing no longer give specific details of emergency procedures for individual UN numbers and class 9 includes products with no common danger, information on spillage procedures should be obtained from other sources such as package labels and safety data sheets.
Recall: The general instruction from the core module
Do not walk into or touch spilled substances and avoid inhalation of fumes, smoke, dusts and vapours by staying up wind.
Where appropriate and safe to do so, use on-board equipment to prevent leakages into the aquatic environment or the sewage system and to contain spillages.

7. PPE 5.7 Gloves Goggles 5.7.7 Appropriate personal protective equipment
Recall: That the instructions in writing list the general PPE require for each class.
State: Additional PPE may be required and the consignor should provide details when this is the case.
