extinguishing media appropriate for surrounding fire. 
Special Information: Firefighters
should wear proper protective equipment and self-contained breathing apparatus
with full facepiece operated in positive pressure mode.
Wear
self-contained breathing apparatus and full protective clothing. With clean
shovel, carefully place material into clean, dry container and cover; remove
from area. Flush spill area with water.
Keep container tightly closed.
Store in secure poison area. Containers of this material may be hazardous when
empty since they retain product residues (dust, solids); observe all warnings
and precautions listed for the product.
Airborne Exposure Limits: None
established. 
Ventilation System: A
system of local and/or general exhaust is recommended to keep employee exposures
as low as possible. Local exhaust ventilation is generally preferred because it
can control the emissions of the contaminant at its source, preventing
dispersion of it into the general work area. Please refer to the ACGIH document, Industrial
Ventilation, A Manual of Recommended Practices, most recent edition, for
details. 
Personal Respirators (NIOSH Approved): For
conditions of use where exposure to the substance is apparent and engineering
controls are not feasble, consult an industrial hygienist. For emergencies, or
instances where the exposure levels are not known, use a full-facepiece
positive-pressure, air-supplied respirator. WARNING: Air purifying respirators
do not protect workers in oxygen-deficient atmospheres. 
Skin Protection: Wear
impervious protective clothing, including boots, gloves, lab coat, apron or
coveralls, as appropriate, to prevent skin contact. 
Eye Protection: Use
chemical safety goggles and/or full face shield where dusting or splashing of
solutions is possible. Maintain eye wash fountain and quick-drench facilities in
work area.
