Inhalation Remove from exposure. If breathing stops or shows signs of failing, give artificial respiration. Obtain medical attention urgently. Keep warm and at rest. If there is difficulty in breathing, give oxygen. Do not use mouth to mouth ventilation.
Skin Contact Immediately flood the skin with large quantities of water, preferably under a shower. Remove contaminated clothing as washing proceeds. Contaminated clothing should be washed or dry-cleaned before re-use. Obtain medical attention if blistering occurs or redness persists.
Ingestion Wash mouth out with water. Give sips of cold water or milk to soothe the affected parts. Do not induce vomiting.
Eye Contact Immediately flood the eye with plenty of water for at least 10 minutes, holding the eye open. Obtain medical attention urgently.

5. Fire Fighting Measures

Extinguishing Media Not combustible. Use appropriate equipment based on other constituents of fire.
Unusual hazards May decompose to form toxic fumes of sulphur oxides and sulphuric acid.
Protective Equipment Fire-fighters should wear self-contained positive pressure breathing apparatus (SCBA) and full turnout gear.

6. Accidental Release Measures

Ventilate the area to dispel possible toxic decomposition fumes. Wear appropriate protective clothing. Sweep up into suitable containers for recovery or disposal. Advise Authorities if spillage has entered water course or sewer or has contaminated soil or vegetation.

7. Handling and Storage

Use in well ventilated area. Avoid contact with eyes, skin and clothing. Emergency shower and eye wash facilities should be readily available. Storage area should be cool, covered, well-ventilated, dry and well away from sources of heat or ignition. Water contamination should be avoided. Do not store in metal containers.

8. Exposure Controls/Personal Protection

Appropriate exhaust ventilation or other engineering controls must be used to keep the airborne concentrations of vapours below their respective threshold limit value. Use respiratory protection if there is risk of breathing mists or vapours from heated material. The limit in the EH.40 Occupational Exposure Limits 1991 is -8hr TWA 2.5,g/M2.

Ensure that eyewash stations and safety showers are close to the workstation location. Wash hands after handling compounds and before eating, smoking, using lavatory and at the end of the day.
