Specific extinguishing : Collect contaminated fire extinguishing water separately. This must not be
methods discharged into drains. Fire residues and contaminated fire extinguishing water
must be disposed of in accordance with local regulations. In the event of fire
and/or explosion do not breathe fumes.

Section: 6. ACCIDENTAL RELEASE MEASURES

Personal precautions, : Ensure adequate ventilation. Keep people away from and upwind of spill/leak.
protective equipment and Avoid inhalation, ingestion and contact with skin and eyes. When workers are
emergency procedures facing concentrations above the exposure limit they must use appropriate
certified respirators. Ensure clean-up is conducted by trained personnel only.
Refer to protective measures listed in sections 7 and 8.

Environmental precautions : Do not allow contact with soil, surface or ground water.

Methods and materials for : Stop leak if safe to do so. Contain spillage, and then collect with non-
containment and cleaning up combustible absorbent material, (e.g. sand, earth, diatomaceous earth,
vermiculite) and place in container for disposal according to local / national
regulations (see section 13). For large spills, dike spilled material or otherwise
contain material to ensure runoff does not reach a waterway. Flush away traces
with water. DEACTIVATION SOLUTION - prepare a fresh solution of 5% sodium
bicarbonate and 5% sodium hypochlorite in water (i.e. add 50 grams of sodium
bicarbonate per 1 liter of household bleach, seal container then shake well for 1
minute) away from the immediate area of spill. Prepare 10 times the estimated
volume of the residual spill. The materials and equipment for preparing solutions
should be kept available for use in areas where spills may occur.

Section: 7. HANDLING AND STORAGE

Advice on safe handling : Avoid contact with skin and eyes. Do not ingest. Do not breathe
dust/fume/gas/mist/vapours/spray. Do not get in eyes, on skin, or on clothing.
Wash hands thoroughly after handling. Use only with adequate ventilation.

Conditions for safe storage : Keep out of reach of children. Keep container tightly closed. Store in suitable
labelled containers.

Suitable material : Keep in properly labelled containers.

Unsuitable material : The following compatibility data is suggested based on similar product data
and/or industry experience: Compatibility with Plastic Materials can vary; we

Persistence and degradability

The organic portion of this preparation is expected to be readily biodegradable.

Mobility

The environmental fate was estimated using a level III fugacity model embedded in the EPI (estimation program
interface) Suite TM, provided by the US EPA. The model assumes a steady state condition between the total
input and output. The level III model does not require equilibrium between the defined media. The information
provided is intended to give the user a general estimate of the environmental fate of this product under the
defined conditions of the models.
If released into the environment this material is expected to distribute to the air, water and soil/sediment in the
approximate respective percentages;

Air : <5%
Water : 30 - 50%
Soil : 50 - 70%

The portion in water is expected to be soluble or dispersible.

Bioaccumulative potential

This preparation or material is not expected to bioaccumulate.
