sand or other non-combustible material. Do not touch spilled material. Prevent entry into sewers, basements or
confined areas; dike if needed. Be careful that the product is not present at a concentration level above TLV.
Check TLV on the MSDS and with local authorities.

Handling and Storage
Precautions:
Keep away from heat. Keep away from sources of ignition. Ground all equipment containing material. Do not
ingest. Do not breathe gas/fumes/ vapor/spray. Wear suitable protective clothing. In case of insufficient
ventilation, wear suitable respiratory equipment. If ingested, seek medical advice immediately and show the
container or the label. Avoid contact with skin and eyes.
Storage:
Store in a segregated and approved area. Keep container in a cool, well-ventilated area. Keep container tightly
closed and sealed until ready for use. Avoid all possible sources of ignition (spark or flame).

Exposure Controls/Personal Protection
Engineering Controls:
Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their
respective threshold limit value. Ensure that eyewash stations and safety showers are proximal to the
work-station location.
Personal Protection:
Splash goggles. Lab coat. Vapor respirator. Be sure to use an approved/certified respirator or equivalent.
Gloves.
Personal Protection in Case of a Large Spill:
Splash goggles. Full suit. Vapor respirator. Boots. Gloves. A self contained breathing apparatus should be
