Environmental precautions

Personal precautions

Move containers from spill area. Approach the release from upwind. Prevent entryinto sewers, water courses, basements or confined areas. Vacuum or sweep upmaterial and place in a designated, labelled waste container. Dispose of via alicensed waste disposal contractor. Note: see section 1 for emergency contactinformation and section 13 for waste disposal.

6. Accidental release measures

:

: No action shall be taken involving any personal risk or without suitable training.Evacuate surrounding areas. Keep unnecessary and unprotected personnel fromentering. Do not touch or walk through spilt material. Provide adequate ventilation.Wear appropriate respirator when ventilation is inadequate. Put on appropriatepersonal protective equipment (see section 8).

Avoid dispersal of spilt material and runoff and contact with soil, waterways, drainsand sewers. Inform the relevant authorities if the product has caused environmentalpollution (sewers, waterways, soil or air).

Large spill :

Move containers from spill area. Vacuum or sweep up material and place in adesignated, labelled waste container. Dispose of via a licensed waste disposalcontractor.

Handling

Handling and storage

Storage

7.Put on appropriate personal protective equipment (see section 8). Eating, drinkingand smoking should be prohibited in areas where this material is handled, stored andprocessed. Workers should wash hands and face before eating, drinking andsmoking. Do not get in eyes or on skin or clothing. Do not ingest. Use only withadequate ventilation. Wear appropriate respirator when ventilation is inadequate.Keep in the original container or an approved alternative made from a compatiblematerial, kept tightly closed when not in use. Empty containers retain product residueand can be hazardous. Do not reuse container.

Store between the following temperatures: 5 to 30°C (41 to 86°F). Store inaccordance with local regulations. Store in original container protected from directsunlight in a dry, cool and well-ventilated area, away from incompatible materials (seesection 10) and food and drink. Keep container tightly closed and sealed until readyfor use. Containers that have been opened must be carefully resealed and keptupright to prevent leakage. Do not store in unlabelled containers. Use appropriatecontainment to avoid environmental contamination.

Recommended monitoringprocedures

If this product contains ingredients with exposure limits, personal, workplaceatmosphere or biological monitoring may be required to determine the effectivenessof the ventilation or other control measures and/or the necessity to use respiratoryprotective equipment. Reference should be made to European Standard EN 689 formethods for the assessment of exposure by inhalation to chemical agents andnational guidance documents for methods for the determination of hazardoussubstances.

8. Exposure controls/personal protection

Hand protection

Use a properly fitted, air-purifying or air-fed respirator complying with an approvedstandard if a risk assessment indicates this is necessary. Respirator selection mustbe based on known or anticipated exposure levels, the hazards of the product and thesafe working limits of the selected respirator.Chemical-resistant, impervious gloves complying with an approved standard shouldbe worn at all times when handling chemical products if a risk assessment indicatesthis is necessary.Safety eyewear complying with an approved standard should be used when a riskassessment indicates this is necessary to avoid exposure to liquid splashes, mists,gases or dusts.

Skin protection Personal protective equipment for the body should be selected based on the taskbeing performed and the risks involved and should be approved by a specialist beforehandling this product.

:

Environmental exposurecontrols

: Emissions from ventilation or work process equipment should be checked to ensurethey comply with the requirements of environmental protection legislation. In somecases, fume scrubbers, filters or engineering modifications to the process equipmentwill be necessary to reduce emissions to acceptable levels.

Occupational exposurecontrols

: Use only with adequate ventilation. If user operations generate dust, fumes, gas,vapour or mist, use process enclosures, local exhaust ventilation or other engineeringcontrols to keep worker exposure to airborne contaminants below any recommendedor statutory limits.

Wash hands, forearms and face thoroughly after handling chemical products, beforeeating, 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 safetyshowers are close to the workstation location.
