Guidance on Safe Use
Administrative data
First-aid measures
General advice: Under the shower: Take off immediately all contaminated clothing. including shoes.
Inhalation:
Move patient from contaminated area to fresh air. Oxygen or artificial respiration if needed. Keep under 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: If entering a saturated atmosphere, wear a self contained breathing apparatus. Protective suit
Fire-fighting measures
- Suitable extinguishing media: Water spray, Foam, Dry powder, Carbon dioxide (CO2)
- Unsuitable extinguishing media: High volume water jet
Special hazards arising from the substance or mixture:
Flammable. Possible re-ignition of vapours from a distance . Warm impregnated insulating material can, with time, ignite spontaneously
Thermal decomposition giving flammable and toxic products: Peroxides
Precautions for fire-fighters:
Specific methods: Use water spray to cool unopened containers. Ensure containers can be rapidly moved. In case of fire nearby, remove exposed containers.
Special protective actions for fire-fighters: wear self-contained breathing apparatus. Complete suit protecting against chemicals
Accidental release measures
Personal precautions, protective equipment and emergency procedures:
Ensure adequate ventilation. Evacuate personnel to safe areas. Prohibit all sources of sparks and ignition - Do not smoke. Use personal protective equipment. Avoid contact with skin and eyes and inhalation of vapours.
Environmental precautions:
Prevent product from entering drains. Dam up with sand or inert earth (do not use combustible materials). Should not be released into the environment.
Methods and materials for containment and cleaning up:
- Recovery:
Pump into a labelled inert emergency tank. Moist product : absorb the remainder with an inert absorbent material. Capture the gas with fine water spray (scrubbing), collect and treat contaminated water.
- Elimination:
Destroy the product by incineration (in accordance with local and national regulations).
Handling and storage
Precautions for safe handling:
- Technical measures/Precautions:
Storage and handling precautions applicable to products: Liquid. Flammable. Toxic. Provide appropriate exhaust ventilation at machinery.
Provide showers, eye-baths. Provide water supplies near the point of use. Provide fire-blanket nearby. Provide waterproof electrical
equipment. Provide self-contained breathing apparatus nearby. Well ventilate empty vats and tanks before entering.
Safe handling advice:
Prohibit all sources of sparks and ignition - Do not smoke. Use only in an area containing explosion proof equipment.
Hygiene measures:
Avoid inhalation of vapours. Do not get in eyes, on skin, or on clothing. 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. Store protected from moisture and heat. Remove all sources of ignition. Provide a
catch-tank in a bunded area. Provide electrical earthing of equipment and electrical equipment usable in explosive atmospheres.
- Incompatible products: Strong oxidizing agents, Amines
Packaging material:
Recommended: Ordinary steel, Stainless steel, Protected glass (for small quantities)

EXPOSURE CONTROLS:
This substance must be handled under Strictly Controlled Conditions in accordance with REACH regulation Article 18(4).
Site documentation to support safe handling arrangements including the selection of engineering, administrative and personal protective equipment controls in accordance with risk-based management systems must be available at each Manufacturing/using site.
Written confirmation of application of strictly controlled conditions has been received from every affected downstream manufacturer/user of this substance.
General protective measures: Use high inegrity methods of material loading and unloading. Investigate engineering techniques to reduce exposures. Ensure sufficient air exchange and/or exhaust in work areas. Routine monitoring and inspection for leaks to reduce fugitive emissions.
Personal protective equipment:
Respiratory protection:
Low concentrations or short activity: Mask with specific cartridge Recommended Filter type: A2B2E2K2P3
High concentrations or prolonged activity: Self contained Breathing Apparatus
Hand protection: Gloves (PVC, neoprene) According to permeation index EN 374: 1 (time elapsed > 10 mins)
Eye/face protection: Safety glasses
Skin and body protection: At the workplace: Protective clothing (cotton)
Intervention at incident: Waterproof suit
Environmental exposure controls : Do not release into the environment. In case of waste, use techniques to minimize the emissions : incineration or any treatment to minimize the level of release (ex WWTP).
Stability and reactivity
Reactivity & Chemical stability: Stable under recommended storage conditions.
Conditions to avoid:
