We know the danger symbols? The question is not strange given that between 2010 and 2015 they gradually changed to make them the same across Europe. Today for the risks deriving from chemicals, substances and mixtures, there are i chemical hazard symbols, or hazard pictograms, or simply danger symbols.
THE danger symbols they serve to inform about the types of dangers related to the use, handling, transport and storage of dangerous chemicals. Before they were black in an orange square framed in black, today they are inserted in a red rhomboid frame.
The new criteria in the classification of risks, and i new danger symbols, were introduced with EC Regulation 1272/2008 which replaced Annex II of Directive 67/548 / EEC. With obligation from 1 December 2010 for 'substances' and from 1 June 2015 for 'mixtures'.
Hazard symbols or hazard pictograms
Explosive. GHS01 name: indicates substances or preparations which can explode with a spark or are extremely sensitive to impact or friction. Flames, sources of heat, shaking and rubbing must be avoided. Example: nitroglycerin.
Corrosive.GHS05 name: indicates chemicals that cause the destruction of living tissue or equipment. Inhalation and contact with eyes, skin and clothes should be avoided. Example: sulfuric acid.
Flammable. GHS02 name: indicates all products and preparations that can overheat and catch fire on contact with ignition sources but also on contact with water and air. This pictogram brings together the previous 'flammable' and 'extremely flammable' of the old classification. Contact with materials, water and air must be avoided. Examples: benzene (flammable), hydrogen (extremely flammable).
Acute toxic. GHS06 name: substances or preparations which, by inhalation, ingestion or penetration into the skin, cause serious, acute or chronic risks and even death. Contact with the body should be avoided. Example: cyanide.
severe long-term toxic effects
Severe effects. GHS08 name: substances or preparations which, when inhaled, ingested or absorbed through the skin, cause extremely serious, acute or chronic risks and easily death. Contact and repetitive exposure should be avoided even at low concentrations. Example: methanol.
Oxidant.GHS03 name: products which, reacting with other substances, can easily oxidize or release oxygen, aggravating fires of combustible substances. Contact with combustible materials must be avoided. Example: oxygen.
Harmful irritant.GHS07 name: non-corrosive substances or preparations which, upon immediate or prolonged contact with the skin, can cause an irritant action or allergic reactions. Vapors should not be inhaled and skin contact should be avoided. Examples: calcium carbonate, laudanum.
gas under pressure
Gas under pressure. GHS04 designation: this danger symbol, which did not exist in the previous classification, indicates cylinders or other containers of gas under pressure, dissolved, liquefied, compressed or refrigerated. The symbol requires caution in transporting and handling. Example: acetylene.
dangerous for the environment
Dangerous for the environment.GHS09 name. It indicates that the contact with the environment of these substances and preparations causes damage to the ecosystem (flora, fauna, water, air ...) in the short and long term. These substances must not be dispersed into the environment. Example: sodium hypochlorite.
