6. Accidental release measures
Stop leak if without risk. Move containers from spill area. Use spark-proof tools and
explosion-proof equipment. 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 (see Section 13). Dispose of via a
licensed waste disposal contractor. Contaminated absorbent material may pose the
same hazard as the spilled product. Note: see Section 1 for emergency contact
information and Section 13 for waste disposal.
Stop leak if without risk. Move containers from spill area. Use spark-proof tools and
explosion-proof equipment. Dilute with water and mop up if water-soluble. Alternatively,
or if water-insoluble, absorb with an inert dry material and place in an appropriate waste
disposal container. Dispose of via a licensed waste disposal contractor.
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.
Put on appropriate personal protective equipment (see Section 8). 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.
Avoid exposure - obtain special instructions before use. Do not get in eyes or on skin or
clothing. Do not breathe vapor or mist. Do not ingest. 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 non-sparking tools. Take precautionary measures against
electrostatic discharges. To avoid fire or explosion, dissipate static electricity during
transfer by grounding and bonding containers and equipment before transferring
material. Empty containers retain product residue and can be hazardous. Do not reuse
container.

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.
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 or
dusts. If contact is possible, the following protection should be worn, unless the
assessment indicates a higher degree of protection: chemical splash goggles.
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.

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.
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.
Wash hands, forearms and face thoroughly after handling chemical products, before
eating, smoking and using the lavatory and at the end of the working period.
Appropriate techniques should be used to remove potentially contaminated clothing.
Wash contaminated clothing before reusing. Ensure that eyewash stations and safety
showers are close to the workstation location.
