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".
