Phosphoric acid, 2-ethylhexyl ester

Guidance on Safe Use

First-aid measures

INHALATION :Remove to fresh air, treat symptomatically. If symptoms develop, seek medical advice.SKIN CONTACT :Immediately wash with plenty of soap and water. If symptoms develop, seek medical advice.EYE CONTACT :Immediately flush eye with water for at least 15 minutes while holding eyelids open. Get medical attention.INGESTION :If conscious, washout mouth and give water to drink. Get medical attention.NOTE TO PHYSICIAN :Based on the individual reactions of the patient, the physician's judgement should be used to control symptoms and clinical condition.

Fire-fighting measures

EXTINGUISHING MEDIA :Foam, Carbon dioxide, Dry powder, Other extinguishing agent suitable for Class B fires, For large fires, use water spray or fog, thoroughly drenching the burning material. Water mist may be used to cool closed containers.UNSUITABLE EXTINGUISHING MEDIA :Do not use water unless flooding amounts are available.FIRE AND EXPLOSION HAZARD :Combustible Liquid; may form combustible mixtures at or above the flash point. Empty substance containers may contain product residue. Do not pressurize, cut, heat, weld, or expose containers to flame or other sources of ignition. May evolve oxides of carbon (COx) under fire conditions. May evolve oxides of phosphorus (POx) under fire conditions.SPECIAL PROTECTIVE EQUIPMENT FOR FIRE FIGHTING :In case of fire, wear a full face positive-pressure self contained breathing apparatus and protective suit.

Accidental release measures

PERSONAL PRECAUTIONS :Restrict access to area as appropriate until clean-up operations are complete. Use personal protective equipment. Stop or reduce any leaks if it is safe to do so. Ventilate spill area if possible. Remove sources of ignition. Ensure clean-up is conducted by trained personnel only. Do not touch spilled material. Have emergency equipment (for fires, spills, leaks, etc.) readily available. Notify appropriate government, occupational health and safety and environmental authorities.METHODS FOR CLEANING UP :SMALL SPILLS: Soak up spill with absorbent material. Place residues in a suitable, covered, properly labeled container. Wash affected area.LARGE SPILLS: Contain liquid using absorbent material, by digging trenches or by diking. Reclaim into recovery or salvage drums or tank truck for proper disposal. Clean contaminated surfaces with water or aqueous cleaning agents. Contact an approved waste hauler for disposal of contaminated recovered material. Dispose of material in compliance with regulations ENVIRONMENTAL PRECAUTIONS :Prevent material from entering sewers or waterways.

Handling and storage

HANDLING :Do not get in eyes, on skin, on clothing. Do not take internally. Use with adequate ventilation. Do not breathe aerosols. Keep the containers closed when not in use. Have emergency equipment (for fires, spills, leaks, etc.) readily available. Ensure all containers are labeled. Do not use, store, spill or pour near heat, sparks or open flame.STORAGE CONDITIONS :Store in suitable labeled containers. Store the containers tightly closed. Store away from heat and sources of ignition. Have appropriate fire extinguishers available in and near the storage area. Connections must be grounded to avoid electrical charges. Store separately from oxidizers.SUITABLE CONSTRUCTION MATERIAL :Carbon Steel C1018, Stainless Steel 304, Stainless Steel 316L, Surface-modified HDPE (high density polyethylene), Perfluoroelastomer, TFE, FEP (encapsulated), Compatibility with Plastic Materials can vary; it is recommended that compatibility is tested prior to use.UNSUITABLE CONSTRUCTION MATERIAL :Neoprene, Nitrile, EPDM

Exposure controls / personal protection

ENGINEERING MEASURES :General ventilation is recommended. The use of local exhaust ventilation is recommended to control emissions near the source. Laboratory samples should be handled in a fumehood. Provide mechanical ventilation of confined spaces.PERSONAL PROTECTIONGENERAL ADVICE :The use and choice of personal protection equipment is related to the hazard of the substance, the workplace and the way the substance is handled. In general, as a minimum precaution  safety glasses with side-shields and workclothes protecting arms, legs and body should be used. In addition any person visiting an area where this substance is handled should at least wear safety glasses with side-shields. The applicable Europeanstandard can be found in EN 166.RESPIRATORY PROTECTION :At ambient temperature none needed for vapour. If the substance is heated or if aerosol generation is likely, use of a half face filter mask. A suitable filter material depends on the amount and type of chemicals being handled. Consider the use of filter type: A-P. The applicable European standard can be found in EN 140, EN 137, EN 143 and EN 14387. In event of emergency or planned entry into unknown concentrations a positive pressure, full-face piece SCBA should be used. If respiratory protection is required, institute a complete respiratory protection program including selection, fit testing, training, maintenance and inspection.HAND PROTECTION :When handling this substance, the use of chemical gauntlets is recommended. The choice of work glove depends on work conditions and what chemicals are handled, for light handling conditions consider using gloves made from PVC. Gloves should be replaced immediately if signs of degradationare observed. The applicable European standard can be found in EN 374.SKIN PROTECTION :When handling this substance, the use of overalls, a chemical resistant apron and rubber boots is recommended. The applicable European standard can be found in EN ISO 20345.EYE PROTECTION :When handling this substance, the use of face-shield and splash chemical goggles is recommended. The applicable European standard can be found in EN 166.HYGIENE RECOMMENDATIONS :Keep an eye wash fountain available. Keep a safety shower available. If clothing is contaminated, remove clothing and thoroughly wash the affected area. Launder contaminated clothing before reuse.ENVIRONMENTAL EXPOSURE CONTROL PRECAUTIONS :Consider the provision of containment around storage vessels.

Stability and reactivity

STABILITY :Stable under normal conditions. Thermal decompositon can occur under certain processing conditions, it is strongly recommended that the company Best Practice Guide is strictly adhered to for injection of this chemical into process streams. A copy of the guide is available on request.HAZARDOUS POLYMERIZATION :Hazardous polymerization will not occur.CONDITIONS TO AVOID :Heat and sources of ignition including static discharges.MATERIALS TO AVOID :Contact with strong oxidizers (e.g. chlorine, peroxides, chromates, nitric acid, perchlorate, concentrated oxygen, permanganate) may generate heat, fires, explosions and/or toxic vapors.HAZARDOUS DECOMPOSITION PRODUCTS :Under fire conditions: Oxides of carbon, Oxides of phosphorus

Disposal considerations

Use only authorized contractors. Ensure compliance with EC, national and local regulations.Dispose of wastes in an approved incinerator or waste treatment/disposal site, in accordance with all applicable regulations.
