3. Hazards identification

Causes severe burns.

4. First aid measures

First-aid personnel: ensure self-protection! After inhalation: fresh air. Summon doctor. After skin contact: wash off with plenty of water. Dab with polyethylene glycol 400. Immediately remove contaminated clothing. After eye contact: rinse out with plenty of water for at least 10 minutes with the eyelid held wide open. Immediately summon eye specialist. After swallowing: make victim drink plenty of water (if necessary several litres), avoid vomiting (risk of perforation!). Immediately summon doctor. Do not attempt to neutralize.

5. Fire-fighting measures

Suitable extinguishing media:

Water, foam, powder. Fire extinguisher: powder , carbon dioxide , water

Special risks:

Combustible. Vapours heavier than air. Formation of hazardous combustion gases or vapours possible in event of fire. Contain escaping vapours with water. Keep away from sources of ignition. Formation of explosive mixtures possible with air. Hydrogen may form upon contact with metals (danger of explosion!). The following may develop in event of fire: carbon monoxide

Special protective equipment for fire fighting:

Do not stay in dangerous zone without suitable chemical protection clothing and self-contained breathing apparatus.

Other information:

Contain escaping vapours with water. Cool containers with water.

6. Accidental release measures

Person-related precautionary measures: Do not inhale vapours/aerosols. Avoid substance contact. Procedures for cleaning / absorption: Take up with liquid-absorbent material (e.g. Chemizorb® ). Forward for disposal. Clean up affected area. Environmental-protection measures: Do not allow to enter sewerage system. Additional notes: Render harmless: neutralize with sodium bicarbonate or diluted sodium hydroxide solution.

7. Handling and storage

Handling:

No further requirements.

Storage:

Tightly closed. Dry. In a well-ventilated place. Protected from light. Keep away from sources of ignition and heat. At +15°C to +25°C. May decompose forming gaseous products, especially when stored over long periods.

8. Exposure controls/personal protection

Specific control parameter
MAK Germany (max. workplace conc.)
Formic acid	5 ml/m3 or 9.5 mg/m3

Personal protective equipment:
Respiratory protection:	required when vapours/aerosols are generated. Filter B (acc. to DIN 3181) for inorganic gases and vapours
Eye protection:	required
Hand protection:	required Protective clothing should be selected specifically for the working place, depending on concentration and quantity of the hazardous substances handled. The resistance of the protective clothing to chemicals should be ascertained with the respective supplier.
Other protective equipment:	Acid-resistant protective clothing.
Industrial hygiene:	Immediately change contaminated clothing. Apply skin- protective barrier cream. Wash hands and face after working with substance.

11. Toxicological information

Acute toxicity

LD50 (oral, rat): 1100 mg/kg ; LC50 (inhalation, rat): 15 g/m3 /15 min ; The literature data available to us do not conform with the labelling prescribed by the EC. The EC has dossiers of the manufacturers which have not been published.

Subacute to chronic toxicity

An embryotoxic effect need not be feared when the threshold limit value is observed.

Further toxicological information

After inhalation of vapours: Irritation symptoms in the respiratory tract. dyspnoea After skin contact: skin lesions After eye contact: conjunctivitis , Lacrimal irritation due to vapours. After swallowing: Burns in oesophagus and stomach. mucosal irritations , acidosis Damage of: kidneys

Further data

Further hazardous properties cannot be excluded. The product should be handled with the care usual when dealing with chemicals.

12. Ecological information

***Harmful effect due to pH shift. When used properly, no impairments in the function of waste- water-treatment plants are to be expected. Neutralization possible in waste water treatment plants. Fish toxicity: L.idus LC50: 120 mg/l ; ; Daphnia toxicity: Daphnia LC50: 34.2 mg/l ; Algeal toxicity: Scenedesmus subspicatus EC50: 25.0 mg/l ; Bacterial toxicity: Ps.pudita EC50: 46.7 mg/l ; Further ecologic data: Degradability: BOD5: 0.27 g/g ; ThOD: 0.35 g/g Do not allow to enter waters, waste water, or soil!

13. Disposal considerations

Product:

There are no uniform EC Regulations for the disposal of chemicals or residues. Chemical residues generally count as special waste. The disposal of the latter is regulated in the EC member countries through corresponding laws and regulations. We recommend that you contact either the authorities in charge or approved waste disposal companies which will advise you on how to dispose of special waste.

Packaging:

Disposal in compliance with official regulations. Handle contaminated packaging in the same way as the substance itself. If not officially specified differently, non-contaminated packaging may be treated like household waste or recycled.
