6. Accidental Release Measures
Steps to be Taken if Material is Released or Spilled: Contain spilled material if possible. Absorb
with materials such as: Sawdust. Dirt. Vermiculite. Sand. Clay. Cob grit. Milsorb®. Do NOT use
absorbent materials such as: Cement powder (Note: may generate heat). Collect in suitable and
properly labeled open containers. Do not place in sealed containers. Suitable containers include:
Metal drums. Plastic drums. Polylined fiber pacs. Wash the spill site with large quantities of water.
Attempt to neutralize by adding suitable decontaminant solution: Formulation 1: sodium carbonate 5 -
10%; liquid detergent 0.2 - 2%; water to make up to 100%, OR Formulation 2: concentrated ammonia
solution 3 - 8%; liquid detergent 0.2 - 2%; water to make up to 100%. If ammonia is used, use good
ventilation to prevent vapor exposure. Pump with explosion-proof equipment. If available, use foam to
smother or suppress. Contact Dow for clean-up assistance. See Section 13, Disposal
Considerations, for additional information.
Personal Precautions: Isolate area. Keep unnecessary and unprotected personnel from entering the
area. Keep personnel out of low areas. Keep personnel out of confined or poorly ventilated areas.
Keep upwind of spill. Ventilate area of leak or spill. Confined space entry procedures must be
followed before entering the area. Eliminate all sources of ignition in vicinity of spill or released vapor
to avoid fire or explosion. Check area with combustible gas detector before reentering area. Ground
and bond all containers and handling equipment. See Section 10 for more specific information. Refer
to Section 7, Handling, for additional precautionary measures. Use appropriate safety equipment. For
additional information, refer to Section 8, Exposure Controls and Personal Protection.
Environmental Precautions: Prevent from entering into soil, ditches, sewers, waterways and/or
groundwater. See Section 12, Ecological Information. Spills or discharge to natural waterways is likely
to kill aquatic organisms.
7. Handling and Storage
Handling
General Handling: Avoid contact with eyes, skin, and clothing. Wash thoroughly after handling. Use
only with adequate ventilation. Avoid breathing vapor. Keep container closed. No smoking, open
flames or sources of ignition in handling and storage area. Vapors are heavier than air and may travel
a long distance and accumulate in low lying areas. Ignition and/or flash back may occur. Contents
under pressure. Do not puncture or incinerate container. Containers, even those that have been
emptied, can contain vapors. Do not cut, drill, grind, weld, or perform similar operations on or near
empty containers. Do not enter confined spaces unless adequately ventilated. See Section 8,
EXPOSURE CONTROLS AND PERSONAL PROTECTION.
Storage
Protect from atmospheric moisture. Flammable mixtures may exist within the vapor space of
containers at room temperature. Minimize sources of ignition, such as static build-up, heat, spark or
flame. Maintain a nitrogen atmosphere. Do not store product contaminated with water to prevent
potential hazardous reaction. See Section 10 for more specific information. Store in a dry place.
Shelf life: Use within Storage temperature:
12 Months 20 - 30 °C
