Guidance on Safe Use

First-aid measures

General information Remove affected person from source of contamination. Get medical attention.

Inhalation Remove person to fresh air and keep comfortable for breathing. Place unconscious person on their side in the recovery position and ensure breathing can take place. Maintain an open airway. Loosen tight clothing such as collar, tie or belt. When breathing is difficult, properly trained personnel may assist affected person by administering oxygen. If breathing stops, provide artificial respiration. Get medical attention.

Ingestion Move affected person to fresh air and keep warm and at rest in a position comfortable for breathing. Loosen tight clothing such as collar, tie or belt. Do not induce vomiting unless under the direction of medical personnel. Rinse nose and mouth with water. Never give anything by mouth to an unconscious person. Place unconscious person on their side in the recovery position and ensure breathing can take place. Get medical attention.

Skin contact Rinse immediately contaminated clothing and skin with plenty of water before removing clothes. Wash with plenty of water. Continue to rinse for at least 15 minutes. Get medical attention if any discomfort continues.

Eye contact Remove affected person from source of contamination. Remove any contact lenses and open eyelids wide apart. Rinse with water. Continue to rinse for at least 15 minutes and get medical attention.

Protection of first aiders First aid personnel should wear appropriate protective equipment during any rescue. For personal protection, see Section 8.

Most important symptoms and effects, both acute and delayed

General information See Section 11 for additional information on health hazards.

Inhalation Vapours may irritate throat/respiratory system.

Ingestion May cause discomfort if swallowed.

Skin contact A single exposure may cause the following adverse effects: Redness. Irritation.

Eye contact A single exposure may cause the following adverse effects: Redness. Irritation.

Notes for the doctor Treat symptomatically.

Fire-fighting measures

Suitable extinguishing media Use fire-extinguishing media suitable for the surrounding fire. Extinguish with alcohol-resistant foam, carbon dioxide, dry powder or water fog.

Unsuitable extinguishing media Do not use water jet as an extinguisher, as this will spread the fire.

Specific hazards Dust may form explosive mixture with air. Thermal decomposition or combustion products may include the following substances: Toxic and corrosive gases or vapours.

Hazardous combustion products - Thermal decomposition or combustion products may include the following substances: Toxic and corrosive gases or vapours. Carbon monoxide (CO).

Protective actions during firefighting

In case of fire: Evacuate area. No action shall be taken without appropriate training or involving any personal risk. Fight fire from safe distance or protected location. Keep upwind to avoid inhalation of gases, vapours, fumes and smoke. Contain and collect extinguishing water. Avoid the spillage or runoff entering drains, sewers or watercourses. If risk of water pollution occurs, notify appropriate authorities.

Special protective equipment for firefighters

Wear positive-pressure self-contained breathing apparatus (SCBA) and appropriate protective clothing. Firefighter's clothing conforming to European standard EN469 (including helmets, protective boots and gloves) will provide a basic level of protection for chemical incidents.

Accidental release measures

Personal precautions No smoking, sparks, flames or other sources of ignition near spillage. Take precautionary measures against static discharges. Do not touch or walk into spilled material. Avoid inhalation of dust and contact with skin and eyes. Do not enter storage areas or confined spaces unless adequately ventilated. Use suitable respiratory protection if ventilation is inadequate. Wear protective clothing as described

Environmental precautions Avoid or minimise the creation of any environmental contamination. Avoid the spillage or runoff entering drains, sewers or watercourses. Environmental Manager must be informed of all major spillages. Spillages or uncontrolled discharges into watercourses must be reported immediately to the Environmental Agency or other appropriate regulatory body.

Methods for cleaning up Wear protective clothing as described in Section 8 of this safety data sheet. Eliminate all  ignition sources if safe to do so. If involved in a fire, shut off flow if it can be done without risk. Provide adequate ventilation. Do not touch or walk into spilled material. To prevent release, place container with damaged side up. Remove spillage with vacuum cleaner or collect with a shovel and broom, or similar. Collect and place in suitable waste disposal containers and seal

securely.

Handling and storage

Usage precautions For use in industrial installations or professional treatment only. Do not handle until all safety precautions have been read and understood. Do not eat, drink or smoke when using this product. Wear protective clothing as described. Do not handle broken packages without protective equipment. Avoid breathing dust. Mechanical ventilation or local exhaust ventilation may be required. If ventilation is inadequate, suitable respiratory protection must be worn. Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking. Take precautionary measures against static discharges. Do not empty into drains.

Advice on general occupational hygiene Do not smoke in work area. Good personal hygiene procedures should be implemented. Wash at the end of each work shift and before eating, smoking and using the toilet. Wash promptly if skin becomes contaminated. Take off immediately all contaminated clothing and wash it before reuse. Eye wash facilities and emergency shower must be available when handling this product. Warn cleaning personnel of any hazardous properties of the product.

Storage precautions Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No  smoking. Keep in a cool, well ventilated place. Protect from freezing and direct sunlight. Keep away from food, drink and animal feeding stuffs. Keep away from oxidising materials, heat and flames. Store in a demarcated bunded area to prevent release to drains and/or watercourses.

Storage class Chemical storage.

Exposure controls / personal protection

Ingredient comments No exposure limits known for ingredient(s).

Appropriate engineering controls

Provide adequate ventilation. Mechanical ventilation or local exhaust ventilation may be required. Observe any occupational exposure limits for the product or ingredients. Static electricity and formation of sparks must be prevented.

Eye/face protection Tight-fitting safety glasses. Personal protective equipment for eye and face protection should comply with European Standard EN166. If inhalation hazards exist, a full-face respirator may be required instead.

Hand protection Chemical-resistant, impervious gloves complying with an approved standard should be worn if a risk assessment indicates skin contact is possible. To protect hands from chemicals, gloves should comply with European Standard EN374. For exposure up to 4 hours, wear gloves made of the following material: Butyl rubber. Nitrile rubber. Thickness: ~ 0.4 mm The most suitable glove should be chosen in consultation with the glove supplier/manufacturer, who can

provide information about the breakthrough time of the glove material. Considering the data specified by the glove manufacturer, check during use that the gloves are retaining their protective properties and change them as soon as any deterioration is detected. Frequent changes are recommended.

Other skin and body protection

Wear appropriate clothing to prevent any possibility of skin contact. Refer to European Standard EN 1149 for information on material and design requirements and test methods. Hygiene measures Provide eyewash station and safety shower. Good personal hygiene procedures should be implemented. Wash promptly if skin becomes contaminated. Take off immediately all contaminated clothing and wash it before reuse. Change work clothing daily before leaving workplace. Do not eat, drink or smoke when using this product.
