Guidance on Safe Use

First-aid measures

Inhalation: Get medical attention immediately. Call a poison center or physician. Remove victimto fresh air and keep at rest in a position comfortable for breathing. If it is suspectedthat fumes are still present, the rescuer should wear an appropriate mask or selfcontainedbreathing apparatus. If not breathing, if breathing is irregular or ifrespiratory 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.  Call a poison center or physician.  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.  Chemical burns must be treated promptly by a 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. Skin contact:Get medical attention immediately.  Call a poison center or physician.  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.  Chemical burns must be treated promptly by a physician.  Wash clothing before reuse.  Clean shoes thoroughly before reuse. Eye contact: Get medical attention immediately.  Call a poison center or physician.  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.  Chemical burns must be treated promptly by a physician.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.Notes to physician: Symptomatic treatment and supportive therapy as indicated. Following severeexposure the patient should be kept under medical review for at least 48 hours.

Fire-fighting measures

Suitable extinguishig media: Use an extinguishing agent suitable for the surrounding fire.Special exposure hazards: In a fire or if heated, a pressure increase will occur and the container may burst.  This material is toxic to aquatic life with long lasting effects.  Fire water contaminated with this material must be contained and prevented from being discharged to any waterway, sewer or drain.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.Hazardous thermal decomposition products:Decomposition products may include the following materials:carbon dioxidecarbon monoxidesulfur oxidesSpecial protective equipment for fire-fighters: Fire-fighters should wear appropriate protective equipment and self-containedbreathing apparatus (SCBA) with a full face-piece operated in positive pressuremode. Clothing for fire-fighters (including helmets, protective boots and gloves)conforming to European standard EN 469 will provide a basic level of protection forchemical incidents.

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.  Do not breathe vapour or mist.  Provide adequate ventilation.  Wear appropriate respirator when ventilation is inadequate.  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).  Water polluting material.  May be harmful to the environment if released in large quantities.  Collect spillage.Methods for cleaning up: Stop leak if without risk.  Move containers from spill area.  Approach the release from upwind.  Prevent entry into sewers, water courses, basements or confined areas.  Wash spillages into an effluent treatment plant or proceed as follows.  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.  

Handling and storage

Handling: Put on appropriate personal protective equipment. 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. Remove contaminated clothing and protective equipment before enteringeating areas. Do not get in eyes or on skin or clothing. Do not breathe vapour or mist.Do not swallow. If during normal use the material presents a respiratory hazard, useonly with adequate ventilation or wear appropriate respirator. Keep in the originalcontainer or an approved alternative made from a compatible material, kept tightlyclosed when not in use. Keep away from acids. Empty containers retain productresidue and can be hazardous. Do not reuse container.Storage: Store between the following temperatures: 5 to 40°C (41 to 104°F).  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 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 unlabelled containers.  Use appropriate containment to avoid environmental contamination.Recommended packaging materials: Use original container.
