Guidance on Safe Use

First-aid measures

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 adverse health effects persist or are severe. 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.

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 adverse health effects persist or are severe. 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.

Skin contact:

Flush contaminated skin with plenty of water. Remove contaminated clothing and shoes. Continue to rinse for at least 10 minutes. Get medical attention. Wash clothing before reuse. Clean shoes thoroughly before reuse.

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.

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.

Notes to physician:

Symptomatic treatment and supportive therapy as indicated. Following severe exposure the patient should be kept under medical review for at least 48 hours.

Fire-fighting measures

Extinguishing media Suitable : Use dry chemical, CO2, water spray (fog) or foam.

Not suitable : Do not use water jet.

Special exposuer hazards:

Highly flammable liquid and vapour.  In a fire or if heated, a pressure increase will occur and the container may burst, with the risk of a subsequent explosion.  The vapour/gas is heavier than air and will spread along the ground.  Vapours may accumulate in low or confined areas or travel a considerable distance to a source of ignition and flash back.  Runoff to sewer may create fire or explosion hazard.  This material is very toxic to aquatic life.  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.  Move containers from fire area if this can be done without risk.  Use water spray to keep fire-exposed containers cool.

Hazardous thermal decomposition products:

Decomposition products may include the following materials:

carbon dioxide

carbon monoxide

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:

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.  Shut off all ignition sources.  No flares, smoking or flames in hazard area.  Avoid breathing 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.

Large spill:

Stop leak if without risk.  Move containers from spill area.  Use spark-proof tools and explosion-proof equipment.  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, 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. Do not swallow.  Avoid contact with eyes, skin and clothing.  Avoid breathing vapour or mist.  Avoid release to the environment.  Use only with adequate ventilation.  Wear appropriate respirator when ventilation is inadequate.  Do not enter storage areas and confined spaces unless adequately ventilated.  Keep in the original container or an approved alternative made from a compatible material, kept tightly closed when not in use.  Store and use away from heat, sparks, open flame or any other ignition source.  Use explosion-proof electrical (ventilating, lighting and material handling) equipment.  Use only non-sparking tools.  Take precautionary measures against electrostatic discharges.  Empty containers retain product residue and can be hazardous.  Do not reuse container.

Storage:

Store in accordance with local regulations.  Store in a segregated and approved area.  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.  Eliminate all ignition sources.  Separate from oxidizing materials.  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 materials recommended: use original container

Exposure controls / personal protection

Recommended monitoring procedures:

If this product contains ingredients with exposure limits, personal, workplace atmosphere or biological monitoring may be required to determine the effectiveness of the ventilation or other control measures and/or the necessity to use respiratory protective equipment. Reference should be made to monitoring standards, such as the following: European Standard EN 689 (Workplace atmospheres - Guidance for the assessment of exposure by inhalation to chemical agents for comparison with limit values and measurement strategy) European Standard EN 14042 (Workplace atmospheres - Guide for the application and use of procedures for the assessment of exposure to chemical and biological agents) European Standard EN 482 (Workplace atmospheres - General requirements for the performance of procedures for the measurement of chemical agents) Reference to national guidance documents for methods for the determination of hazardous substances will also be required.

Occupational exposure controls:

Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or other engineering controls to keep worker exposure to airborne

contaminants below any recommended or statutory limits. The engineering controls also need to keep gas, vapour or dust concentrations below any lower

explosive limits. Use explosion-proof ventilation equipment.

Environmental exposure controls:

Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels.

Respiratory pretection:

In case of inadequate ventilation wear respiratory protection. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product and the safe working limits of the selected respirator.

Hand protection:

Chemical-resistant, impervious gloves complying with an approved standard should be worn at all times when handling chemical products if a risk assessment indicates this is necessary.  Considering the parameters specified by the glove manufacturer, check during use that the gloves are still retaining their protective properties.  It should be noted that the time to breakthrough for any glove material may be different for different glove manufacturers.  In the case of mixtures, consisting of several substances, the protection time of the gloves cannot be accurately estimated.

Chemical-resistant, impervious gloves complying with an approved standard should be worn at all times when handling chemical products if a risk assessment indicates this is necessary.
