4. FIRST AID MEASURES
Ingestion
After inhalation: fresh air. Immediately call in physician. If breathing stops: immediately apply artificial respiration, if necessary also oxygen.
Inhalation
If not breathing, give artificial respiration. Remove from exposure, lie down. Donot usemouth-to-mouth method if victim ingested or inhaled the substance; give artificial respirationwith the aid of a pocket mask equipped with a one-way valve or other proper respiratorymedical device. Call a physician immediately.
Skin Contact
In case of skin contact: Take off immediately all contaminated clothing. Rinse skin with water/ shower. Consult a physician.
Eye Contact
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.
Immediate medical attention is required.
Immediate medical attention is required.
Other Information
Show this material safety data sheet to the doctor in attendance.
Symptoms of poisoning may even occur after several hours; therefore medical observation for at least 48 hours after the accident.
Causes burns by all exposure routes. May cause allergic skin reaction. Symptoms of allergic reaction may include rash, itching, swelling, trouble breathing, tinglingof thehandsand feet, dizziness, lightheadedness, chest pain, muscle pain or flushing: Ingestionmaycause gastrointestinal irritation, nausea, vomiting and diarrhea: Product is a corrosivematerial. Use of gastric lavage or emesis is contraindicated. Possible perforation of stomach or esophagus should be investigated: Ingestion causes severe swelling, severedamage to the delicate tissue and danger of perforation.

Engineering controls
Ensure that eyewash stations and safety showers are close to the workstation location. Wherever possible, engineering control measures such as the isolation or enclosure of the process, the introduction of processorequipment changes to minimise release or contact, and the use of properly designed ventilation systems, should be adoptedtocontrol hazardous materials at source
Personal protective equipment
Eye and face protection
Wear tightly sealed goggles.
Avoid contact with the eyes and skin.
Avoid contact with the eyes and skin.
Skin protection
Protective gloves
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. As the product is a preparation of several substances, the resistance of
the glove material can not be calculated in advance and has therefore to be checked prior to the application.
