Keep away from open flames, hot surfaces and sources of ignition. Keep container tightly
closed in a dry and well-ventilated place. Keep in properly labeled containers.
Handling
Keep away from open flames, hot surfaces and sources of ignition. Take precautionary
measures against static discharges. Use only in an area containing flame proof equipment.
To avoid ignition of vapors by static electricity discharge, all metal parts of the equipment
must be grounded. Take necessary action to avoid static electricity discharge (which might
cause ignition of organic vapors). Do not breathe vapors or spray mist. Contents under
pressure.

Eyewash stations. Showers. Explosion proof ventilation systems.
Exposure Guidelines
Methods for Containment
If possible, turn leaking containers so that gas escapes rather than liquid. Allow substance
to evaporate.
Personal Protective Equipment
Eye/Face Protection
Safety glasses with side-shields.
Personal Precautions
Chemical Name
Skin and Body Protection
Wear fire/flame resistant/retardant clothing. Antistatic boots Neoprene gloves.
ACGIH TLV OSHA PEL
Respiratory Protection
If exposure limits are exceeded or irritation is experienced, NIOSH/MSHA approved
respiratory protection should be worn. Positive-pressure supplied air respirators may be
required for high airborne contaminant concentrations. Respiratory protection must be
provided in accordance with current local regulations.

Dam up. Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal
binder, sawdust). Pick up and transfer to properly labeled containers. Soak up with inert
absorbent material.
ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area).
Evacuate personnel to safe areas. Keep people away from and upwind of spill/leak. Take
precautionary measures against static discharges. All equipment used when handling the
product must be grounded.
