1.2. Advice for emergency responders
- The product evaporates readily.
- Ensure adequate ventilation.
- Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing.
- Keep away from open flames, hot surfaces and sources of ignition.
2. Environmental precautions
- Should not be released into the environment.
3. Methods and materials for containment and cleaning up
- Allow to evaporate.
4. Reference to other sections
- Refer to protective measures listed in sections "HANDLING AND STORAGE" and "EXPOSURE CONTROLS/PERSONAL PROTECTION".
Handling and storage

2. Conditions for storage, including incompatibilities
2.1. Storage
- Keep in properly labelled containers.
- Keep in container fitted with safety valve or vent.
- Vapours are heavier than air and may spread along floors.
- Keep in a cool, well-ventilated place.
- Keep away from heat and sources of ignition.
- Keep away from combustible material.
- Keep away from Incompatible products.
- Provide tight electrical equipment well protected against corrosion.
- Refer to protective measures listed in sections 7 and 8.
