prevent explosive rupture.
SECTION 6: Accidental release measures
6.1. Personal precautions, protective equipment and emergency procedures
Evacuate area. Keep away from heat/sparks/open flames/hot surfaces. - No smoking. Use only non-sparking tools.
Ventilate the area with fresh air. For large spill, or spills in confined spaces, provide mechanical ventilation to disperse or
exhaust vapors, in accordance with good industrial hygiene practice. Warning! A motor could be an ignition source and could
cause flammable gases or vapors in the spill area to burn or explode. Refer to other sections of this SDS for information
regarding physical and health hazards, respiratory protection, ventilation, and personal protective equipment.
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
Contain spill. 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 closed 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.
