This colorless liquid sinks and does not mix with water. It could harm marine life or water supply systems and could cause long-term effects in the aquatic environment. This chemical has a chloroform-like odor.
This chemical is toxic Poisonous; can injure or kill people or other organisms by ingestion and skin absorption. Vapors can cause dizziness or suffocate exposed people. Contact can irritate or burn skin and eyes.
This chemical can produce toxic smoke and fumes if burned.
Vapors are heavier than air. They may spread along the ground and collect in low and/or confined spaces such as vessel holds, sewers, and basements.
For
spill volumes much larger than a railroad tank car, the following distance
estimates may be too short.
Spills onto LAND OR A SOLID SURFACE:
As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions.
In case of a LARGE SPILL, consider initial downwind evacuation for at least 100 meters (330 feet).
If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.
