First-aid measures
INHALATION:
Get medical attention immediately. Move exposed person to fresh air. Keep person warm and at rest. 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. 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. In case of inhalation of decomposition products in a fire, symptoms may be delayed. The exposed person may need to be kept under medical surveillance for 48 hours.
INGESTION:
Get medical attention immediately. Wash out mouth with water. Move exposed person to fresh air. Keep person warm and at rest. 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. 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.
SKIN CONTACT:
Get medical attention immediately. Wash skin immediately with plenty of water and soap. Subsequent cleansing with polyethyleneglycol 400, then again with water and soap. In case of blueness of lips, skin or nails (cyanosis) let the person breathe oxygen. Continue to rinse for at least 10 minutes. Remove contaminated clothing and shoes. No consumption of alcohol after product contact. No physical exertion. Wash clothing before reuse. Clean shoes thoroughly before reuse.
EXYE CONTACT:
Get medical attention immediately. 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.
NOTES TO THE PHYSICIAN:
Elementary aid, decontamination, symptomatic treatment and depending on the formation of methaemoglobin: intravenous administration of toluidine blue or other redox dyes according to dosage specifications plus ascorbic acid.
Fire-fighting measures
EXTINGUISHING MEDIA
Suitable: In case of fire, use water spray (fog), foam, dry chemical or CO2.
Not suitable: None known.
SPECIAL EXPOSURE HAZARDS: In a fire or if heated, a pressure increase will occur and the container may burst. 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. This material is very toxic to aquatic organisms. Fire water contaminated with this material must be contained and prevented from being discharged to any waterway, sewer or drain.
HAZARDOUS COMBUSTION PRODUCTS: Decomposition products may include the following materials: carbon oxides, nitrogen oxides, halogenated compounds
SPECIAL PROTECTIVE EQUIPEMENT FOR FIRE-FIGHTERS: Fire-fighters should wear appropriate protective equipment and selfcontained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode.
REMARK: Cool closed containers exposed to fire with water. Never use water jet.
Accidental release measures
PERSONAL PRECAUTIONS:
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 spilt material. Avoid breathing vapour or mist. Provide adequate ventilation. Put on appropriate personal protective equipment.
ENVIRONMENTAL PRECAUTIONS:
Avoid dispersal of spilt 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). Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.
LARGE SPILL:
Stop leak if without risk. Move containers from spill area. Prevent entry into sewers, water courses, basements or confined areas.
Contain and collect spillage with non-combustible, absorbent material e.g. sand, earth, vermiculite or diatomaceous earth and place in container for disposal according to local regulations. Dispose of via a licensed waste disposal contractor. Contaminated absorbent material may pose the same hazard as the spilt product.
SMALL SPILL:
Stop leak if without risk. Move containers from spill area. Dilute with water and mop up if water-soluble or absorb with an inert dry material and place in an appropriate waste disposal container. Dispose of via a licensed waste disposal contractor.
Handling and storage
HANDLING:
Put on appropriate personal protective equipment. 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. Do not get in eyes or on skin or clothing. Do not breathe vapour or mist. 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.
STORAGE:
Store in accordance with local regulations. Store in original container protected from direct sunlight in a dry, cool and wellventilated area, away from incompatible materials and food and drink. 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 unlabelled containers. Use appropriate containment to avoid environmental contamination.
PACKAGING MATERIAL:
Recommended: Use original container.
Remarks: Take precautionary measures against electrostatic discharges. Avoid all possible sources of ignition (spark or flame). Ensure effective ventilation. Vent waste air only via suitable separators or scrubbers.
