Guidance on Safe Use

First-aid measures

General information:

Avoid chance of exposure by any feasible way.

After inhalation:

Move the affected person to fresh air. If breathing becomes irregular or ceases, apply mouth-to-mouth resuscitation or artifical respiration immediately. Get medical attention.

Do not induce vomiting.

Information for doctor:

The physician must be informed on the time, type and extent of exposure. If needed, show the safety data sheet to the physician.

Fire-fighting measures

Suitable extinguishing media:

The extinguishing media must be chosen depending on the characteristics of burning substance.

Available extinguishing media: water spray, carbon dioxid, extinguishing powder, foam.

Unsuitable extinguishing media:

Full water-jet are not suitable for extinguishing.

Special hazards arising from the substance or mixture:

Substance is combustible. Combustion products: carbonmonoxide/-dioxide.

Accidental release measures

Personal precautions, protective equipment and emergency procedures:

Avoid direct contact between the personnel and the substance.

Only the trained personnel in charge is allowed to be present at the site of spilling, wearing the prescribed protective equipments.

Environmental precautions:

Hinder the spilled substance from entering the soil, sewers or living water.

Methods and material for containment and cleaning up:

Spilt substance must be enclosed and soaked up by sand or earth, then it must be collected into spare empties and transported to the place of disposal. Wash the contaminated area with plenty of water.

Handling and storage

Precautions for safe handling:

Handled it the compliance with good industrial hygiene and safety procedures.

All work processes must always be designed so minimize or exclude the risk of exposure.

Avoid any possibility of direct contact with substance while manipulating.

Avoid: contact with skin, eyes; inhalation or ingestion.

Conditions for safe storage, including any incompatibilities:

Store it in a cool, dry, well-ventilated, free from direct sunlight place. Keep container tightly closed and sealed until ready for use. Do not store in unlabelled containers. Use appropriate containment to avoid environmental contamination.

Storage temperature: 2-8 °C. Inner packing: PP barrel.

Do not store together with substances specified in section Stability and reactivity.

SpecialProvisions

Exposure controls / personal protection

This intermediate is handled under Strictly Controlled Conditions in accordance with the ECHA REACH Guidance on Intermediates.

The substance is rigorously contained during storage, the packaging is opened only in case of sampling, and when the substance is used in the process. When the substance is put in the reactor, air filtration (99% efficiency) is used along with personal protective equipment. The process is thereafter fully closed; no emission is detected until sampling of the reaction mass. During sampling air filtration (99% efficiency) is used along with personal protective equipment. At the end of the process, during the unloading of the substance and the sampling general air filtration is used along with personal protective equipment.

No occupational limits have been established.

Individual protection measures / personal protective equipment:

The personal protective equipment for the working process are determined by internal standards.

Wear closed protection glasses. Sealed, liquid chemical protective clothing. Protective gloves made of nitrile and butyl. Dust mask with A2 or other filter cartridge which provides higher protection.

Stability and reactivity

The substance is stabil at cool, dry place for 12 months.

Chemical stability:

Stable is defined storage conditions in section Handling and storage properly.

Possibility of hazardous reactions:

May react with substance specified in section Incompatible materials

Vapours may form explosive mixture with air.

Incompatible materials:

Strong oxidisers.

Disposal considerations

Suggestions for disposal procedures of the substance/product:

Incineration in a special waste incineration plant.

Since material catches fire relatively hard, it is useful to feed it into the incinerator dissolved in a flammable solvent.

Suggestions for disposal procedures of contaminated packaging (vessels):

Flammable empties must be incinerated in waste increation plant, in compliance with local regulations.
