6.2. Environmental precautions
Avoid release to the environment. For larger spills, cover drains and build dikes to prevent entry into sewer systems or
bodies of water.
6.3. Methods and material for containment and cleaning up
Cover spill area with a fire-extinguishing foam. An appropriate aqueous film forming foam (AFFF) is recommended.
Working from around the edges of the spill inward, cover with bentonite, vermiculite, or commercially available inorganic
absorbent material. Mix in sufficient absorbent until it appears dry. Remember, adding an absorbent material does not
remove a physical, health, or environmental hazard. Collect as much of the spilled material as possible using non-sparking
tools. Place in a metal container approved for transportation by appropriate authorities. Clean up residue with an
appropriate solvent selected by a qualified and authorized person. Ventilate the area with fresh air. Read and follow safety
precautions on the solvent label and SDS. Seal the container. Dispose of collected material as soon as possible in
accordance with applicable local/regional/national/international regulations.
SECTION 7: Handling and storage
7.1. Precautions for safe handling
Keep out of reach of children. Do not handle until all safety precautions have been read and understood. Keep away from
heat/sparks/open flames/hot surfaces. - No smoking. Use only non-sparking tools. Take precautionary measures against
static discharge. Do not breathe dust/fume/gas/mist/vapours/spray. Do not get in eyes, on skin, or on clothing. Do not
eat, drink or smoke when using this product. Wash thoroughly after handling. Avoid release to the environment. Avoid
contact with oxidizing agents (eg. chlorine, chromic acid etc.) Wear low static or properly grounded shoes. Use personal
protective equipment (gloves, respirators, etc.) as required. To minimize the risk of ignition, determine applicable electrical
classifications for the process using this product and select specific local exhaust ventilation equipment to avoid flammable
vapor accumulation. Ground/bond container and receiving equipment if there is potential for static electricity accumulation
during transfer.
7.2. Conditions for safe storage including any incompatibilities
Store in a well-ventilated place. Keep cool. Keep container tightly closed. Store away from heat. Store away from
acids. Store away from strong bases. Store away from oxidizing agents.
