Guidance on Safe Use

First-aid measures

No action shall be taken involving any personal risk or without suitable training.  It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation.

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 if irritation occurs.

Inhalation: Remove victim to fresh air and keep at rest in a position comfortable for breathing.  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 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.  Get medical attention if symptoms occur.  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 adverse health effects persist or are severe.  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.

Fire-fighting measures

Extinguishing media: Use dry chemical, CO₂, water spray (fog) or foam.Do not use water jet.

Advice for firefighters: 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. 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

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.  Shut off all ignition sources.  No flares, smoking or flames in hazard area.  Avoid breathing vapor or mist.  Provide adequate ventilation.  Wear appropriate respirator when ventilation is inadequate.  Put on appropriate personal protective equipment.

Spill: Stop leak if without risk.  Move containers from spill area.  Approach 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.  Use spark-proof tools and explosion-proof equipment.  Dispose of via a licensed waste disposal contractor.  Contaminated absorbent material may pose the same hazard as the spilled product.

Handling and storage

Precaution for safe handling: Put on appropriate personal protective equipment (see Section 8).  Do not ingest.  Avoid contact with eyes, skin and clothing.  Avoid breathing vapor or mist.  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.

Conditions for safe 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 (see Section 10) and food and drink.  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 unlabeled containers.  Use appropriate containment to avoid environmental contamination.

Exposure controls / personal protection

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, vapor or dust concentrations below any lower explosive limits.  Use explosion-proof ventilation equipment.

Safety eyewear complying with an approved standard should be used when a risk assessment indicates this is necessary to avoid exposure to liquid splashes, mists, gases or dusts.  If contact is possible, the following protection should be worn, unless the assessment indicates a higher degree of protection:  safety glasses with side-shields.

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.

Personal protective equipment for the body should be selected based on the task being performed and the risks involved and should be approved by a specialist before handling this product.  When there is a risk of ignition from static electricity, wear anti-static protective clothing.  For the greatest protection from static discharges, clothing should include anti-static overalls, boots and gloves.  Refer to European Standard EN 1149 for further information on material and design requirements and test methods.

Use a properly fitted, air-purifying or air-fed respirator complying with an approved standard if a risk assessment indicates this is necessary.  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.
