First-aid measures

Description of first aid measures

Pay attention to self-protection.

Remove victims from hazardous area. Immediately remove soiled or soaked clothing and remove it to a safe distance. Keep victim warm, in a stabilized position and covered.

Do not leave victims unattended.

If the casualty is unconscious: Place the victim in the recovery position.


Possible discomfort: severe irritation of mucous lining (nose, throat, eyes), cough, sneezing, flow of tears

Move victims into fresh air.

If breathing difficulties occur:

Keep patient half sitting with upper body raised.

Call a physician immediately.

Skin contact

Wash off affected area immediately with plenty of water for at least 15 minutes.

With liposoluble substances, products, or preparations, continue decontamination with polyethylene glycol 400 after initial rinsing with water and then wash with water and soap.

If symptoms persist, consult a physician for treatment.

Eye contact

With eye held open, thoroughly rinse immediately with plenty of water for at least 10 minutes.

Consult an ophthalmologist immediately if the symptoms persist.

When dealing with caustic substances, notify emergency physician immediately (key words: burns in eye).


Rinse mouth.

Immediately give large quantities of water to drink.

Obtain medical attention.

When dealing with caustic substances, notify emergency physician immediately.

Most important symptoms and effects, both acute and delayed


Irritation of skin and mucous membranes

Causes burns.


Headache, vertigo, somnolence (sleepiness), nausea.

Aspiration in the lungs might cause a chemical pneumonia.

Aspiration may cause pulmonary oedema and pneumonitis.

Health injuries may be delayed.


Strongly irritating to corrosive.Harmful by inhalation, in contact with skin and if swallowed.Vapours may cause drowsiness and dizziness.

Indication of any immediate medical attention and special treatment needed

In case of substances with high water solubility, inhalation of vapors, aerosols, mists, and smoke from caustic substances, products, and preparations, as well as caustic gases, results in irritations up to formation of necrosis in the upper respiratory tract.

The initial focus is on the local action: signs of irritation of the respiratory tract such as coughing, burning behind the sternum, tears, burning in the eyes or nose.

There is a fundamental risk of acute toxic pulmonary edema!

In case of substances with low water solubility, only slight local irritations may appear at first, but after several hours of latency without symptoms, may develop into increasingly labored breathing and cyanosis as a result of a delayed pulmonary edema.

There is a danger of underestimating the severity of the intoxication!

Fire-fighting measures

Extinguishing media

Suitable extinguishing media: Water spray, foam, CO2, dry powder.

Unsuitable extinguishing media: high volume water jet

Special hazards arising from the substance or mixture

Hazardous fumes in fires, specific to the product:

nitrogen oxides (NOx)

Carbon oxides

Advice for firefighters

Water for fire fighting must not be introduced in the sewer system, subsoil, or surface waters. Assure that there are sufficient fire water retaining facilities Contaminated fire fighting water must be disposed of in conformity with the regulations of the local authorities.

Fire residues should be disposed of in accordance with the regulations.

In case of fire: wear a self contained respiratory apparatus

Wear suitable protective clothing.
