Guidance on Safe Use

First-aid measures

Description of first aid measures  

 Eye contact : Immediately flush eyes with plenty of water, occasionally lifting the upper and lower eyelids. Check for and remove any contact lenses.

 Continue to rinse for at least 10 minutes. Get medical attention.  

 Inhalation : Remove victim to fresh air and keep at rest in a position comfortable for breathing. If it is suspected that fumes are still present, the

 rescuer should wear an appropriate mask or self-contained breathing apparatus. If not breathing, if breathing is irregular or if respiratory arrest

 occurs, provide artificial respiration or oxygen by trained personnel. It may be dangerous to the person providing aid to give mouth-to-mouth

 resuscitation. Get medical attention. If necessary, call a poison center or physician. If unconscious, place in recovery position and get medical

 attention immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.  

 Skin contact : Flush contaminated skin with plenty of water. Remove contaminated clothing and shoes. Wash contaminated clothing thoroughly with water before removing it, or wear gloves. Continue to rinse for at least 10 minutes. Get medical attention. Wash clothing before reuse. Clean shoes

 thoroughly before reuse.  

 Ingestion : Wash out mouth with water. Remove dentures if any. Remove victim to fresh air and keep at rest in a position comfortable for breathing. If material has been swallowed and the exposed person is conscious, give small quantities of water to drink. Stop if the exposed person feels sick as

 vomiting may be dangerous. Do not induce vomiting unless directed to do so by medical personnel. If vomiting occurs, the head should be kept low so that vomit does not enter the lungs. Get medical attention. If necessary, call a poison center or physician. Never give anything by mouth to an unconscious person. If unconscious, place in recovery position and get medical attention immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.  

 Protection of first-aiders : No action shall be taken involving any personal risk or without suitable training. If it is suspected that fumes are still

 present, the rescuer should wear an appropriate mask or self-contained breathing apparatus. It may be dangerous to the person providing aid to

 give mouth-to-mouth resuscitation. Wash contaminated clothing thoroughly with water before removing it, or wear gloves.

Advice for firefighters  

 Special precautions for fire-fighters : Promptly isolate the scene by removing all persons from the vicinity of the incident if there is a fire. No action

 shall be taken involving any personal risk or without suitable training.  

 Special protective equipment for fire-fighters : Fire-fighters should wear appropriate protective equipment and self-contained breathing apparatus

 (SCBA) with a full face-piece operated in positive pressure mode. Clothing for fire-fighters (including helmets, protective boots and gloves)

 conforming to European standard EN 469 will provide a basic level of protection for chemical incidents.

Accidental release measures

Personal precautions, protective equipment and emergency procedures  

 For non-emergency personnel : No action shall be taken involving any personal risk or without suitable training. Evacuate surrounding areas. Keep

 unnecessary and unprotected personnel from entering. Do not touch or walk through spilled material. Provide adequate ventilation. Wear

 appropriate respirator when ventilation is inadequate. Put on appropriate personal protective equipment.  

 For emergency responders : If specialised clothing is required to deal with the spillage, take note of any information in Section 8 (MSDS) on suitable

 and unsuitable materials. See also the information in "For non-emergency personnel".  

 

 Environmental precautions : Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains and sewers. Inform the relevant

 authorities if the product has caused environmental pollution (sewers, waterways, soil or air). Water polluting material. May be harmful to the

 environment if released in large quantities. Collect spillage.  

Methods and materials for containment and cleaning up  

 Small spill : Move containers from spill area. Vacuum or sweep up material and place in a designated, labeled waste container. Dispose of via a

 licensed waste disposal contractor.  

 Large spill : Move containers from spill area. Approach release from upwind. Prevent entry into sewers, water courses, basements or confined areas. Vacuum or sweep up material and place in a designated, labeled waste container. Dispose of via a licensed waste disposal contractor. Note: see

 section 1 (MSDS) for emergency contact information and section 13 (MSDS) for waste disposal.  

 

 Reference to other sections : See Section 1 (MSDS) for emergency contact information.

See Section 8 (MSDS) for information on appropriate personal protective equipment.

See Section 13 (MSDS) for additional waste treatment information.

Handling and storage

The information in this section contains generic advice and guidance. The list of Identified Uses in Section 1 should be consulted for any available use-specific information provided in the Exposure Scenario(s).  

Precautions for safe handling  

 Protective measures :  

Put on appropriate personal protective equipment (see Section 8). Avoid exposure - obtain special instructions before use. Avoid exposure during

pregnancy. Do not handle until all safety precautions have been read and understood. Do not get in eyes or on skin or clothing. Do not ingest. Avoid release to the environment. Use only with adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Keep in the original

container or an approved alternative made from a compatible material, kept tightly closed when not in use. Empty containers retain product residue

and can be hazardous. Do not reuse container.  

 Advice on general occupational hygiene : Eating, drinking and smoking should be prohibited in areas where this material is handled, stored and

 processed. Workers should wash hands and face before eating, drinking and smoking. Remove contaminated clothing and protective equipment

 before entering eating areas. See also Section 8 for additional information on hygiene measures.  

 

 Conditions for safe storage, including any incompatibilities : Store in accordance with local regulations. Store in original container protected from

 direct sunlight in a dry, cool and well-ventilated area, away from incompatible materials (see section 10) and food and drink. Store locked up. Keep

 container tightly closed and sealed until ready for use. Containers that have been opened must be carefully resealed and kept upright to prevent

 leakage. Do not store in unlabeled containers. Use appropriate containment to avoid environmental contamination.
