Guidance on Safe Use

First-aid measures

Description of first aid measures

Immediately remove contaminated clothing. If the patient is likely to become unconscious, place and transport in stable sideways position (recovery position). If not breathing, give artificial respiration. First aid personnel should pay attention to their own safety.

 

If inhaled:

Keep patient calm, remove to fresh air, seek medical attention. Immediately administer a corticosteroid from a controlled/metered dose inhaler.

 

On skin contact:

Immediately wash thoroughly with plenty of water, apply sterile dressings, consult a skin specialist.

 

On contact with eyes:

Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open, consult an eye specialist.

 

On ingestion:

Immediately rinse mouth and then drink 200-300 ml of water, seek medical attention.

 

Most important symptoms and effects, both acute and delayed

Symptoms: Information, i.e. additional information on symptoms and effects may be included in the GHS labeling phrases, and in the toxicological assessments. Further symptoms are possible.

 

Indication of any immediate medical attention and special treatment needed

Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote. Pulmonary odema prophylaxis. Medical monitoring for at least 24 hours.

 

Fire-fighting measures

Extinguishing media

Suitable extinguishing media:

Water spray, dry powder, foam, carbon dioxide.

 

Special hazards arising from the substance or mixture

Nitrogen oxides, carbon oxides can be released in case of fire. Under certain conditions in case of fire other hazardous combustion products may be generated.

 

Advice for fire-fighters

Special protective equipment:

Wear self-contained breathing apparatus and chemical-protective clothing.

 

Further information:

Collect contaminated extinguishing water separately, do not allow to reach sewage or effluent systems. Dispose of fire debris and contaminated extinguishing water in accordance with official regulations.

 

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Use personal protective clothing. Keep unprotected persons away. Ensure adequate ventilation. Avoid inhalation. Avoid contact with the skin, eyes and clothing.

 

Environmental precautions

Do not discharge into drains/surface waters/groundwater.

 

Methods and material for containment and cleaning up

For small amounts: Pick up with suitable appliance and dispose of.

For large amounts: Pick up with suitable appliance and dispose of.

Wear suitable protective equipment. Dispose of absorbed material in accordance with regulations. To clean the floor and all objects contaminated by this material, use plenty of water.

 

Handling and storage

Precautions for safe handling

Ensure thorough ventilation of stores and work areas. Use only alkali-proof equipment. Product should be worked up in closed equipment as far as possible. Personal protective equipment should be worn during open handling.

 

Protection against fire and explosion:

Prevent electrostatic charge - sources of ignition should be kept well clear - fire extinguishers should be kept handy.

 

Conditions for safe storage, including any incompatibilities

Segregate from acids and acid forming substances.

 

Storage stability:

Storage temperature: < 35 °C

Storage duration: 24 Months

May discolour after lengthy storage.

From the data on storage duration, no agreed statement regarding the warrantee of application properties can be deduced.

 

Specific end use(s)

See exposure scenario(s) in the attachment to the safety data sheet.

Exposure controls / personal protection

Exposure controls

Personal protective equipment

 

Respiratory protection:

Respiratory protection in case of vapour/aerosol release. Combination filter for gases/vapours of organic compounds and solid and liquid particles (f.e. EN 14387 Type A-P2)

 

Hand protection:

Chemical resistant protective gloves (EN 374)

Suitable materials also with prolonged, direct contact (Recommended: Protective index 6, corresponding > 480 minutes of permeation time according to EN 374):

nitrile rubber (NBR) - 0.4 mm coating thickness

polyvinylchloride (PVC) - 0.7 mm coating thickness

butyl rubber (butyl) - 0.7 mm coating thickness

fluoroelastomer (FKM) - 0.7 mm coating thickness

Suitable materials for short-term contact (recommended: At least protective index 2, corresponding > 30 minutes of permeation time according to EN 374)

chloroprene rubber (CR) - 0.5 mm coating thickness

Manufacturer's directions for use should be observed because of great diversity of types.

 

Supplementary note: The specifications are based on tests, literature data and information of glove manufacturers or are derived from similar substances by analogy. Due to many conditions (e.g. temperature) it must be considered, that the practical usage of a chemical-protective glove in practice may be much shorter than the permeation time determined through testing.

 

Eye protection:

Tightly fitting safety goggles (splash goggles) (e.g. EN 166).

 

Body protection:

Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting boots, chemical-protection suit (according to EN 14605 in case of splashes or EN ISO 13982 in case of dust).

 

General safety and hygiene measures

Handle in accordance with good industrial hygiene and safety practice. Wearing of closed work clothing is required additionally to the stated personal protection equipment. Avoid contact with the skin, eyes and clothing. Avoid inhalation of dusts/mists/vapours. Consider the risk management measures as outlined in the exposure scenario. Take off immediately all contaminated clothing. No eating, drinking, smoking or tobacco use at the place of work. Store work clothing separately. Hands and/or face should be washed before breaks and at the end of the shift. Wash contaminated clothing before reuse.
