Guidance on Safe Use
Administrative data
First-aid measures
General advice: Under the shower. Take off immediately all contaminated clothing, including shoes.
Inhalation of vapours/mists : Move to fresh air. Oxygen or artificial respiration if needed. Keep under medical surveillance. In case of problems : Hospitalise.
Skin contact: Wash immediately, abundantly and thoroughly with water. Consult a physician. In case of extensive burns, hospitalize.
Eye contact: Wash open eyes immediately, abundantly and thoroughly for at least 15 minutes. Consult an ophthalmologist immediately.
Ingestion: Do not induce vomiting, rinse mouth and lips with plenty of water if the subject is conscious, then hospitalize
Protection of first-aiders: In case of insufficient ventilation, wear suitable respiratory equipment.
Fire-fighting measures
Suitable extinguishing media: Water spray
Specific hazards:
Dry residue : Contact with combustible material may cause fire. Drying the solid using heat can lead to violent exothermic decomposition
Specific methods: In case of fire nearby, remove exposed containers. Cool containers / tanks with water spray.
Special protective actions for fire-fighters: Wear a self contained breathing apparatus. Complete suit protecting against chemicals
Accidental release measures
Personal precautions, protective equipment and emergency procedures:
Prohibit contact with skin and eyes and inhalation of vapours. Use personal protective equipment. Ensure adequate ventilation. In case of insufficient ventilation, wear suitable respiratory equipment.
Environmental precautions:Do not release into the environment. Do not let product enter drains. Dam up and absorb on an inert material.
Methods and materials for containment and cleaning up:
Recovery: Pump into a clean labelled emergency container After cleaning, flush away traces with water. recover water for later processing
Neutralisation: Neutralize contaminated water with a sodium thiosulphate solution
Handling and storage
Precautions for safe handling: Technical measures/Precautions:
Storage and handling precautions applicable to products: Liquid. Corrosive. with suffocating vapours. Dangerous for the environment
Provide appropriate exhaust ventilation at machinery. Provide showers, eye-baths. Provide self-contained breathing apparatus nearby.
Safe handling advice: Avoid splashing when handling. Only dilute with de-ionised water (cationic resin). Provide waterproof electrical equipment.
Hygiene measures: Take off immediately all contaminated clothing. Prohibit contact with skin and eyes and inhalation of vapours. When using do not eat, drink or smoke. Wash hands after handling. Remove contaminated clothing and protective equipment before entering eating areas.
Conditions for safe storage, including any incompatibilities: Keep tightly closed in a dry, cool and well-ventilated place. Use non-combustible construction materials. Store away from moisture and heat to maintain the technical properties of the product. Protect against light. Use only clean equipment. Provide impermeable floor. Provide a catch-tank and anti-corrosion protected electrical equipment in a bunded area. .Store between: 15 °C to 25 °C
Incompatible products: Acids, Ammonia, Combustible material
Packaging material:
Recommended: Vulcanised or rubber coated steel, Polyethylene, Reinforced polyester
To be avoided: Iron, Stainless steel, Copper and copper alloys, Aluminium, Unprotected metals
