Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

First-aid measures

Description of first aid measures:


Remove casualty from area of exposure.  Obtain medical attention for any breathing difficulty.


Give copious amounts of water to drink.  Do not induce vomiting.  Seek medical attention.

Skin contact:

Remove contaminated clothing.  Wash with soap and water.  If irritation develops seek medical attention.

Eye contact:

Flush eyes thoroughly with gently running water for at least 15 minutes.  If irritation develops seek medical attention.

Most important symptoms and effects, both acute and delayed:


May cause irritation to the respiratory tract if dust or fumes are inhaled.


May cause irritation to the gastrointestinal tract and if ingested in large quantities may cause systemic damage.

Skin contact:

May cause irritation to the skin.

Eye contact:

May cause irritation of eyes and mucous membranes.

Indication of any immediate medical attention and special treatment needed:

In case of inhalation of decomposition products in a fire symptoms may be delayed.  The exposed person may need to be kept under medical surveillance for 48 hours.

Fire-fighting measures

Extinguishing media:

Carbon dioxide, dry chemical, alcohol foam.

Unsuitable extinguishing media:

None known.

Special hazards arising from the substance or mixture:

Hazardous combustion products:

Irritating vapours of acetic acid may form during fires.

Advice for firefighters:

Special Fire Fighting Procedures:

Water can be used to cool containers and disperse vapours.  If the material enters rivers, water courses or sewers the appropriate authority should be informed.

Protective equipment for fire-fighters:

Fire fighters must wear protective equipment and clothing sufficient to prevent inhalation of dust or fumes and contact with skin and eyes.

Accidental release measures

Personal precautions, protective equipment and emergency procedures:

Shut off all sources of ignition and evacuate the area.  Wear full protective clothing and respiratory equipment.  Do not inhale dust.

Environmental precautions:

Avoid discharge into drains, water courses or onto the ground.  Spillages or uncontrolled discharges into watercourses must be immediately notified to the appropriate authority.  The product is toxic to aquatic organisms and may cause long term adverse effects in the aquatic environment.

Methods and material for containment and cleaning up:

Clean-up personnel should be trained in the handling of hazardous chemicals and should wear protective equioment and clothing sufficient to prevent inhalation of dust, mist or fumes and contact with skin and eyes.  Transfer carefully into container and arrange for removal bby disposal company.  Prevent from entering sewers or waterways.  If this happens the local authority should be informed.

Handling and storage

Precautions for safe handling:

Exposure by inhalation or skin contact should be minimised by good industrial hygiene practice.  Wear protective clothing as described under Exposure Controls/Personal Protection.  Wash hands after handling.

Conditions for safe storage, including any incompatibilities:

Store in a dry, well-ventillated area out of direct sunlight.  Keep containers tightly closed when not in use and when empty.

Exposure controls / personal protection

Process conditions:

Provide shower and eyewash fountain in work area.

Engineering measures:

Good general ventilation should be sufficient to control worker exposure to airborne contaminants.  If necessary, use process enclosures, local exhaust ventilation or other engineering controls to keep worker exposure below applicable exposure limits.

Respiratory equipment:

The airborne concentration should be kept as low as possible by appropriate ventillation and collection methods.  If this is not available, then an approved dust mask for harmful inorganic dust should be worn.

Skin protection:

Rubber or neoprene gloves.  Other protective clothing, apron, sleeves, coveralls, boots sufficient to prevent contact.

Eye protection:

Goggles or face shield.

Environmental Exposure Controls:

Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of environmental protection legislation.
