HANDLING AND STORAGE
Handling (Personnel)
Avoid-breathing vapor. Avoid liquid contact with eyes and skin. Use with sufficient ventilation to keep
employees exposure below recommended limits. Contact with chlorine or other strong oxidizing agents
should also be avoided. See Fire and Explosion Data section.
Storage
Clean, dry area. Do not heat above 52 deg C (125 deg F).
EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls
Avoid breathing vapors. Avoid contact with skin or eyes. Use with sufficient ventilation to keep employee
exposure below the recommended exposure limit. Local exhaust should be used if large amounts are
released. Mechanical ventilation should be used in low or enclosed places..
Personal Protective Equipment
Impervious gloves should be used to avoid prolonged or repeated exposure. Chemical Splash goggles
should be available for use as needed to prevent eye contact. Under normal manufacturing conditions, no
respiratory protection is required when using this product. Self-contained breathing apparatus (SCBA) is
required if a large release occurs.
