First-aid measures

Product-Specific hazards and other issues:

- Low acute toxicity

- May be moderately irritating to skin and eyes and slightly irritating to respiratory system.

- Harmful: may cause lung damage if swallowed (Aspiration).

- At high doses, effects on the CNS are possible


Seek medical attention.

Remove victim to fresh air and keep at rest in a position comfortable for breathing.

If the casualty is unconscious and:

* Not breathing – ensure that there is no obstruction to breathing and give artificial respiration by trained personnel.  If necessary, give external cardiac massage and obtain medical assistance.

* Breathing - place in the recovery position and keep the head below the level of the torso. Administer oxygen if necessary.

Skin contact

Remove contaminated clothing and footwear, and dispose of safely.

Wash affected area with soap and water.

Seek medical attention if skin irritation, swelling or redness develops and persists.

Eye contact

Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do so. Continue rinsing.

If irritation, blurred vision or swelling occurs and persists, obtain medical advice from a specialist.


In case of ingestion, always assume that aspiration has occurred. The casualty should be sent immediately to a hospital. Do not wait for symptoms to develop.

Do not induce vomiting as there is high risk of aspiration.

Do not give anything by mouth to an unconscious person.

Advice to Physician :

- If inhalation of high concentrations occurs signs and symptoms may include coughing, choking, wheezing, difficulty in breathing, chest congestion, shortness of breath and/or fever. The onset of respiratory symptoms may be delayed.

- Absorption by Inhalation or Ingestion of high doses may cause CNS symptoms like headache, dizziness,   fatigue, muscular, weakness, drowsiness and lack of coordination.

- In case of ingestion the stomach should be emptied by gastric lavage under qualified medical supervision.

Fire-fighting measures

Extinguishing Media

- Alcohol resistant foam (Specifically trained personnel only)

- Water fog (Specifically trained personnel only)

- Dry chemical powder

- Carbon dioxide

Unsuitable Extinguishing Media

Do not use direct water jets on the burning product; they could cause splattering and spread the fire.

Simultaneous use of foam and water on the same surface is to be avoided as water destroys the foam.

Protective Equipment for Fire-fighters

In case of a large fire or in confined or poorly ventilated spaces wear full fire resistant protective clothing and self-contained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode.

Accidental release measures

Environmental precautions :

- This substance is highly volatile, partially water soluble and has only a minimal tendency to

 adhere to soil particles.  

- Even small volumes can pose a threat to the environment and nearby water resources.  

- Surface spills can reach groundwater through porous soil or cracked surfaces.

- All efforts should be made to prevent any leaks or spills, and to protect water resources.  

- Where spills are possible, a comprehensive spill response plan should be developed and


- If a leak or spill reaches the groundwater, the groundwater may become contaminated.  

- If the groundwater is a source of drinking water, the associated drinking water well(s) could

 become contaminated.

Methods for cleaning up :

- Eliminate all sources of ignition.

- All equipment used when handling this product must be grounded.

- Do not touch or walk through spilled material.

- Stop leak if you can do it without risk.

- Prevent entry into waterways, sewers, basements or confined areas.

- A vapor suppressing foam may be used to reduce vapors.

- Absorb or cover with dry earth, sand or other non-combustible material and transfer to


- Use clean non-sparking tools to collect absorbed material. Wipe up with absorbent material.

- Keep in suitable, closed containers for disposal.
