MORE ABOUT DANGEROUS GOODS IN THE WORKPLACE
Moving and storing dangerous goods on your premises can be tricky. Some substances work with other while some combinations can be lethal if careful consideration isn’t taken to which substances don’t work with other. Putting the wrong substances near to each other or in the same room room can cause a dangerous chemical reaction.
DANGEROUS GOODS ARE CLASSIFICATIONDangerous Goods are classified in terms of SANS Code 10228, The identification and classification of dangerous substances and goods, which details the 9 classes (type of hazard), the associated danger groups (degree of hazard), the subsidiary risk, the packing methods and the special provisions relating to dangerous goods.
SANS Code 10228 contains a numerical and alphabetical listing of over 2 500 substances
DANGEROUS GOODS CAN BE BROKEN UP INTO 5 DIFFERENT TYPES OF CLASSES:Solid
THE CHARACTERISTICS OF SIMPLE AND COMPLEX LOADSMost loads that you transport will be relatively simple with an equal weight distribution, regular shape and should have lifting points.
However, you may also encounter loads that are more complex, that are funny shaped and that do not stack nicely. These are called complex loads and need to be dealt with differently than simple loads.
STABILITY AND EQUILIBRIUMThe position of the centre of gravity of an object affects its stability. The lower the centre of gravity (G) is, the more stable the object. The higher it is the more likely the object is to topple over if it is pushed. Racing cars have really low centres of gravity so that they can corner rapidly without turning over.
Increasing the area of the base will also increase the stability of an object, the bigger the area the more stable the object. Rugby players will stand with their feet well apart if they are standing and expect to be tackled.
LOAD DISTRIBUTIONThe way in which we load a vehicle or a forklift may affect the way the vehicle handles. Placing the load too far forward or backward could influence the steering capabilities of the vehicle.
If the load is placed too much to one side, the wheels do not share the weight equally and the vehicle will not travel round corners easily. This is due to the center of gravity that is too close to the side of the vehicle. It is therefore important that the driver supervises the loading of the load and ensures that it is loaded correctly.
The stability of the vehicle is also affected by the height of the load. A load with a high centre of mass (gravity) should be carried on a vehicle with a low platform height (e.g. drop frame trailer or low-bed loader). The higher the load, the easier the vehicle can turn over. The center of gravity for that vehicle changes as the load gets higher, and this will affect the handling of the vehicle. The driver should try to ensure that the load is placed as low and as evenly spread as possible. The load must be positioned on a vehicle in such a manner that the vehicle maintains adequate stability and steering and braking performance, and that the tyres and axles are not overloaded.
WHEN STORING DANGEROUS GOODS TOGETHER ONE NEEDS TO TAKE THE FOLLOWING INTO ACCOUNT:Should the chemicals spill will there be a reaction?
Could a fire or explosion erupt from these goods?
What type of reaction would happen should incompatible chemicals spill in the same room?
Are these self reacting goods?
Could the plant and equipment, such as that used for bulk handling and transfer of goods or in a manufacturing process, be a source of ignition?
MIXED LOADSThe rules require some products to be loaded separately. You cannot load them together in the same cargo space. The table above lists some examples. The regulations (the Segregation Table for Hazardous Materials) name other materials you must keep apart.
