Guidance on Safe Use
Administrative data
First-aid measures
Inhalation causes headaches, dizziness, drowsiness, nausea and may lead to unconsciousness. May cause cancer.
Ingestion : Irritating to mouth, throat and stomach. May cause cancer. Aspiration hazard if swallowed- can enter lungs and cause damage.
Causes skin irritation. Prolonged or repeated contact with skin or mucous membrane may result in irritation symptoms such as redness, blistering, dermatitis, etc.
Eye contact: No specific effects and/or symptoms are known.
Protection for first-aiders: Put on appropriate personal protective equipment (see section 8). Move exposed person to fresh air. Remove contaminated clothing and shoes.
If inhaled, remove to fresh air. Prevent cooling of the person. Keep victim at rest in half-upright position. If not breathing, give artificial respiration. If swallowed, rinse mouth with water (only if the person is conscious). Do not induce vomiting. Take off immediately all contaminated clothing. Wash with soap and water. Eye contact : Rinse with plenty of running water. Obtain medical attention if symptoms occur. Seek medical attention First aid facilities : Ensure that eyewash stations and safety showers are close to the workstation location.
Fire-fighting measures
Small fire Extinguishing media: Suitable: Use dry chemicals, CO2 or alcohol-resistant foam. Cover with vermiculite or other non-combustible material.
Extinguishing media: Not suitable: Do not use water jet
Large fire Extinguishing media: alcohol-resistant foam. Extinguishing media: Not suitable: Do not use water jet. Unusual fire/explosion hazards : Vapour is explosive in air at temperatures higher than the flash point.
Hazardous thermal decomposition products : In case of fire, may produce toxic and/or corrosive decomposition products. Carbon oxides (CO, CO2) Special fire-fighting : Fire water contaminated with this material must be contained and prevented from being discharged
to any waterway, sewer or drain. Protection of fire-fighters : Wear suitable protective clothing. Self-contained breathing apparatus.
Accidental release measures
Personal precautions : Avoid contact with eyes, skin and clothing. Use suitable protective equipment (section 8). Consult
expert immediately. Keep away from sources of ignition. Take precautionary measures against static
discharges. Use explosion-proof electrical (ventilating, lighting and material handling) equipment.
Environmental precautions : Prevent entry into sewers, basements or confined areas. Dyke if necessary. In case of contamination
of aquatic environment, inform local authorities.
Clean-up Methods.
Small spill and leak : Take up with suitable material. Place in a suitable container. Clean up affected area with a large amount of water. Keep away from incompatible materials and avoid specific conditions.
Large spill and leak : Prevent entry into sewers, basements or confined areas. Dyke if necessary. Absorb spill material
with inert material (e.g., dry sand or earth), then place in a chemical waste container. Recycle, if
possible. Use explosion-proof electrical (ventilating, lighting and material handling) equipment. Avoid
release to the environment. This material and its container must be disposed of as hazardous waste.
Fire/explosion hazards Keep away from sources of ignition.
Handling and storage
Handling: Preferably use in closed systems. Use with adequate ventilation. Use suitable protective equipment. Avoid contact with eyes, skin and clothing. Use explosion-proof electrical (ventilating, lighting and material handling) equipment. Take measures against static discharge. Keep away from sources of ignition. Do not allow to enter drains or watercourses.
Storage: Store in a fireproof location. Keep in a cool place. Use appropriate containment to avoid environmental contamination. Keep in a dry place. Keep away from oxidizing substances.
Packaging materials: Recommended : Steel. Aluminium. Synthetic material .

Recommended monitoring procedures
If this product contains ingredients with exposure limits, personal, workplace atmosphere or biological monitoring may be required to determine the effectiveness of the ventilation or other control measures and/or the necessity to use respiratory protective equipment. Reference should be made to European Standard EN 689 for methods for the assessment of exposure by inhalation to chemical agents and national guidance documents for methods for the determination of hazardous substances.
Exposure controls
Occupational exposure controls: Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or other engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits. The engineering controls also need to keep gas, vapour or dust concentrations below any lower explosive limits. Use explosion-proof ventilation equipment.
Hygiene measures: Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period.
Appropriate techniques should be used to remove potentially contaminated clothing.
Wash contaminated clothing before reusing. Ensure that eyewash stations and safety showers are close to the workstation location.
Respiratory protection: Use a properly fitted, air-purifying or air-fed respirator complying with an approved standard if a risk assessment indicates this is necessary. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product and the safe working limits of the selected respirator. Recommended: organic vapour filter (Type A)
Hand protection: Chemical-resistant, impervious gloves complying with an approved standard should be worn at all times when handling chemical products if a risk assessment indicates this is necessary. 1-4 hours (breakthrough time): Viton, polyvinyl alcohol (PVA).
Eye protection: Safety eyewear complying with an approved standard should be used when a risk assessment indicates this is necessary to avoid exposure to liquid splashes, mists or dusts. Recommended: safety glasses with side-shields
Skin protection Personal protective equipment for the body should be selected based on the task being performed and the risks involved and should be approved by a specialist before handling this product.
Environmental exposure controls: Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels.
