Flush with water to chemical sewer.
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
Avoid contact with eyes, skin, or clothing. Wash thoroughly after
handling.
Avoid breathing aerosols and mists (also dust from
dried-down product). Wash contaminated clothing before
reuse and before "SYTON" dries.
Storage
Keep container tightly closed. Store at temperatures above 2 C
(35 F) to avoid irreversible precipitation of silica.
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
Use with sufficient ventilation to keep employee exposure
below recommended exposure limits.
Personal Protective Equipment
Have available and wear as appropriate: chemical splash
goggles and rubber gloves. Where there is potential for
inhalation exposure to product dust, mist, or aerosols in
excess of applicable exposure limits, wear NIOSH/MSHA
approved respiratory protection.
