for firefighters

Specific extinguishing : Fire residues and contaminated fire extinguishing water must
methods 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
protective equipment and spill/leak. Avoid inhalation, ingestion and contact with skin and eyes.
emergency procedures When workers are 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
containment and cleaning up non-combustible absorbent material, (e.g. sand, earth,
diatomaceous earth, vermiculite) and place in container for disposal
according to local / national regulations (see section 13). Flush away
traces with water. For large spills, dike spilled material or otherwise
contain material to ensure runoff does not reach a waterway.
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 : 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 labeled containers.

Suitable material : HDPE (high density polyethylene), PTFE, Polyvinylidene difluoride,

Polypropylene, Plexiglass, Perfluoroelastomer, CPVC (rigid), Buna-
N
Keep in properly labelled containers.

Unsuitable material : The following compatibility data is suggested based on similar

product data and/or industry experience: Shipping and long term
storage compatibility with construction materials can vary; we
therefore recommend that compatibility is tested prior to use.

Degradation leads to the formation of a variety of small organic acids, methylamine, carbon dioxide
and elemental sulfur. The half life of each active substance is dependent upon the initial concentration.

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.
