First-aid measures

Description of first aid measures

First aid personnel should pay attention to their own safety. If the patient is likely to become unconscious, place and transport in stable sideways position (recovery position). Immediately remove contaminated clothing.

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:

Do not induce vomiting. 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 available in Section 2 of the MSDS and in the Toxicological assessments available in Section 11 of the MSDS.

Indication of any immediate medical attention and special treatment needed

Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote.

Fire-fighting measures

Extinguishing media

Suitable extinguishing media:

dry powder, carbon dioxide, foam

Unsuitable extinguishing media for safety reasons:


Special hazards arising from the substance or mixture

Endangering substances: hydrogen chloride

Advice: The substances/groups of substances mentioned can be released in case of fire. Vapours may form explosive mixture with air.

Advice for fire-fighters

Special protective equipment:

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

Further information:

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. Breathing protection required. Ensure adequate ventilation. Avoid all sources of ignition: heat, sparks, open flame. 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 absorbent material (e.g. acid binder). Dispose of absorbed material in accordance with regulations.

For large amounts: Pick up with suitable absorbent material (e.g. acid binder). Dispose of absorbed material in accordance with regulations.

Cleaning operations should be carried out only while wearing breathing apparatus.

Reference to other sections

Information regarding exposure controls/personal protection and disposal considerations can be found in sections "Exposure controls / personal protection" and "Disposal considerations".

Handling and storage

Precautions for safe handling

Ensure thorough ventilation of stores and work areas. Protect against moisture. Refill and handle product only in closed system.

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 amines. Segregate from alkalies and alkalizing substances.

Suitable materials for containers: enamelled, glass, High density polyethylene (HDPE)

Further information on storage conditions: Keep container tightly closed and dry; store in a cool place.

Storage stability:

Storage duration: 6 Months

From the data on storage duration in this safety data sheet no agreed statement regarding the warrantee of application properties can be deduced.

Specific end use(s)

For the relevant identified use(s) listed in Section 1 of the MSDS the advice mentioned in this section is to be observed.

Exposure controls / personal protection

Exposure controls

Personal protective equipment

Respiratory protection:

Self-contained breathing apparatus.


Hand protection:

Chemical resistant protective gloves (EN 374)

Performance level 4, corresponding to a breakthrough time of >120 min according to EN ISO 374-1

fluoroelastomer (FKM) - 0.7 mm coating thickness

Performance level 2, corresponding to a breakthrough time of >30 min according to EN ISO 374-1

butyl rubber (butyl) - 0.7 mm coating thickness

Performance level 1, corresponding to a breakthrough time of >10 min according to EN ISO 374-1

nitrile rubber (NBR) - 0.4 mm coating thickness

chloroprene rubber (CR) - 0.5 mm coating thickness

polyvinylchloride (PVC) - 0.8 mm

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 (cage goggles) (e.g. EN 166) and face shield.


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. Avoid contact with the skin, eyes and clothing. Do not breathe vapour/spray. The substance was registered as a transported isolated intermediate. The manufacturer/importer has received the confirmation by the user that the substance is used under strictly controlled conditions in accordance with art. 18 of the REACH regulation (EC) No 1907/2006. No eating, drinking, smoking or tobacco use at the place of work. Take off immediately all contaminated clothing. Hands and/or face should be washed before breaks and at the end of the shift. Store work clothing separately.

Chemical stability

The product is stable if stored and handled as prescribed/indicated.

Possibility of hazardous reactions

Evolution of corrosive gases/vapours. Reacts with water and basic components to generate heat. On contact with water, gaseous decomposition products are formed, which cause build-up of pressure in tightly closed containers. Reacts with alkalies and metals. Reacts with alcohols, amines, aqueous acids and alkalies. Reacts with water and moisture, with formation of hydrogen chloride. Partly very violent reactions with bases and numerous organic classes of substances such as alcohols and amines. Addition of water leads to increase in temperature. Vapours may form ignitable mixture with air. Substance/product is highly reactive. In damp air hydrochloric acid formation is possible. Violent reactions with water and/or alcohols, with formation of hydrochloric acid. Violent and explosive reaction with water.

Conditions to avoid

Avoid all sources of ignition: heat, sparks, open flame. Avoid direct sunlight. Avoid electro-static charge. Avoid humidity. Avoid heat. Avoid prolonged storage. Disregard of the conditions mentioned may result in undesirable decomposition reactions.

alkaline reactive substances, alcohols, bases, amines, water

Hazardous decomposition products

Hazardous decomposition products:

Disposal considerations
