5-oxo-1-(4-sulphophenyl)-2-pyrazoline-3-carboxylic acid

Guidance on Safe Use

First-aid measures

· After inhalation: Supply fresh air; consult doctor in case of complaints.
· After skin contact: Immediately wash with water and soap and rinse thoroughly.
· After eye contact: Rinse opened eye for several minutes under running water.
· After swallowing: If symptoms persist consult doctor.

Fire-fighting measures

· Suitable extinguishing agents:
CO2, powder or water spray. Fight larger fires with water spray or alcohol resistant foam.
· Special hazards caused by the substance, its products of combustion or resulting gases:
carbon monoxide (CO), carbon dioxide (CO2), sulfur oxides (SOx), other pyrolysis products typical of burning
organic material.
· Protective equipment:
Wear self contained breathing appartus and protective clothing to prevent contact with skin.

Accidental release measures

· Person-related safety precautions: Wear protective equipment. Keep unprotected persons away.
· Measures for environmental protection: Do not allow product to reach sewage system or any water course.
· Measures for cleaning/collecting:
Sweep up, shovel up or vacuum up (consider explosion-proof machines designed to be grounded during storage
and use).
Place spilled material in clean, dry, sealable, labeled container

Handling and storage

· Handling:
· Information for safe handling:
Avoid contact with skin and eyes. Avoid formation of dust and aerosols.
Provide appropriate exhaust ventilation at places where dust is formed. Normal measures for preventive fire protection.

· Storage:
· Requirements to be met by storerooms and receptacles: Provide proper ventilation/exhaustion.
· Information about storage in one common storage facility:
keep away from oxidizing agents i.e. nitrates, oxidizing acids,chlorine bleaches
· Further information about storage conditions:
Store in cool place. Keep container tightly closed in a dry and well-ventilated place.

Exposure controls / personal protection

· Personal protective equipment:
· General protective and hygienic measures:
The usual precautionary measures are to be adhered to when handling chemicals.
· Respiratory protection: Use suitable respiratory protective device in case of insufficient ventilation.
· Protection of hands:
The glove material has to be impermeable and resistant to the product/ the substance/ the preparation.
Due to missing tests no recommendation to the glove material can be given for the product/ the preparation/ the chemical mixture.
Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation
· Material of gloves
The selection of the suitable gloves does not only depend on the material, but also on further marks of quality
and varies from manufacturer to manufacturer.
· Penetration time of glove material
The exact break through time has to be found out by the manufacturer of the protective gloves and has to be
observed.
· Eye protection: Safety glasses
· Body protection: Wear appropraite protective clothing to prevent skin contact.

Stability and reactivity

· Thermal decomposition / conditions to be avoided: No decomposition if used according to specifications.
· Materials to be avoided: oxidizing agents i.e. nitrates, oxidizing acids,chlorine bleaches
· Dangerous decomposition products: carbon monoxide (CO), carbon dioxide (CO2), sulfur oxides (SOx), other pyrolysis products typical of burning
organic material.

Disposal considerations

· Product:
· Recommendation Smaller quantities can be disposed of with household waste.

· Uncleaned packaging:
· Recommendation: Disposal must be made according to official regulations.
