    • Aiman Chaouachi aimantn@gmail.com 2DEFINITIONSSubstances: chemical elements and relevant preparations, either intheir natural state or obtained through specific processes, whichcontain the necessary additives to preserve the product stability andimpurities due to the process adopted, excluding solvents whichmay be separated without affecting the substance stability and withoutaltering its composition;Preparates: mixtures or solutions made up of two or more substances;DANGEROUS SUBSTANCES USE
    • Aiman Chaouachi aimantn@gmail.com 3DEFINITIONSDangerous chemical agents:•Substances and preparates classified and labeled as dangerous by thelaw;•Chemical agents classified as not dangerous, but that should determinean hazard due to chemical, phisycal and toxicological properties and theway of use or storage on work site, included chemical agents with athreshold limit value (TLV).DANGEROUS SUBSTANCES USE
    • Aiman Chaouachi aimantn@gmail.com 4EXAMPLES• Painting.• Welding.• Lubricant or hydraulic oils.• Insulations.DANGEROUS SUBSTANCES USE
    • Aiman Chaouachi aimantn@gmail.com 5HAZARDSHealth and safetyhazardsEnvironmentalhazardsWithin the European Union, all substances and preparations falling into oneor more of the following categories are to be considered hazardous:Substances should be inherently dangerous or can be dangerous due to the wayof use (confined spaces, environmental temperature, etc).DANGEROUS SUBSTANCES USE

MEDICAL FIRST AID MEASURESThis section describes medical and first aid treatments for accidental exposure, also specifying if a physicianis to be consulted. Symptoms and effects, including delayed ones, due to exposure to the hazardoussubstance or preparation shall be indicated as well. This section is subdivided into paragraphs, depending onthe route of exposure to the substance (inhalation, contact, ingestion, etc.)5. FIREFIGHTING MEASURESThis section provides basic fire fighting guidance for trained personnel. It describes what follows:• proper extinguishing materials;• extinguishing materials which shall be used for safety reasons;• possible physical risks in the case of exposure to the substance, combustion products, gases produces,etc.;• protective equipment for trained fire fighters.6. ACCIDENTAL RELEASE MEASURESThis section provides spill, leak and response procedures as to what follows:• Personal precautions: ventilation, respiratory protection, prevention of contact with skin, eyes, etc.• Environmental precautions: keep products/materials far from drains, surface waters, soil, etc.• Cleaning methods: absorbent materials to be used, gas reduction methods, etc.7. HANDLING AND STORAGEThis section provides safe handling and storage information and precautions such as premises ventilation,aerosol and dusts prevention, etc.Storage conditions (temperature, humidity, ventilation, lighting, etc.) as well incompatible materials, quantitylimits, proper electrical plant, etc. are also indicated.DANGEROUS SUBSTANCES USE
