K3. Certain substances in the workplace will have labels on them to identify certain risks that associate with that product. These hazards will be assigned labels that are universally recognised to symbolise what the hazards are. This symbol is used on products that have the potential to explode. What this means is that the substance inside the container has the potential to explode if certain things happen to it, it will cause an explosion. These types of substances should have the label clearly put on the substance and kept inside a coshh cabinet that is earthed to prevent static. When moving explosive materials, they must in the correct packaging to be stored in that complies with 1991 explosive carriage act. This means that they must be labelled with an appropriate UN number. These numbers dictate what kind of packaging is required and in what quantity it can be shipped in, in order to be allowed to be moved safely from one place to another. This symbol is used on substances that are flammable when the right circumstances are met. These circumstances include air water and small ignitions such as static. When storing these substances, the packaging has to clearly show the flammable symbol to warn people handling the substance of the potential danger. In many circumstances these materials must also be moved with care. An example is acetylene which is a very volatile substance stored inside a pressurized bottle. This bottle can only be moved by hand for a maximum of 2m to prevent it becoming volatile and potentially catching on fire or exploding. The main reason for not moving by hand is that the substance is usually dissolved in acetone which when shaken aggressively by moving it, such as churning the bottle will cause the acid dissolvent to become more airborne and therefore more volatile as a result. This symbol is what is used for substances that are oxidizing. This means that can become a catalyst for combustible materials such as explosive materials and flammable materials. On its own it will not become flammable but when exposed to a flammable substance will make that substance substantially more volatile. These substances should be stored well away from any flammable or potentially explosive material for it will cause greater damage if an accident was too occur. This symbol is used on pressurized gas substances. These can be found on any bottled gas that is under pressure. The main hazard for this substance is that because they are under pressure if they are heated, they may explode, not because of the substance itself but because of the condition the substances are in. A common example of such substance is a bottle of argon gas used for welding. This substance is inert and therefore not explosive, but because of the fact it is a pressurized bottle, a significant rise in temperature in the bottle can lead to exploding to the excess pressure. When being transport these bottles should be kept at their ambient temperature, depending on the substance this temperature may be different.
this symbol is used for corrosive materials. Corrosive materials break down
