First Aid Measures
Emergency procedures for chemical exposure incidents
fresh air. Immediately call in physician. If breathing stops: immediately apply artificial respiration, if necessary also oxygen.
Take off immediately all contaminated clothing. Rinse skin with water/ shower. Call a physician immediately.
Symptoms: Drying-out effect resulting in rough and chapped skin.
rinse out with plenty of water. Call in ophthalmologist.
fresh air. Make victim drink ethanol (e.g. 1 drinking glass of a 40% alcoholic beverage). Call a doctor immediately (mention methanol ingestion). Only in exceptional cases, if no medical care is available within one hour, induce vomiting (only in fully conscious persons) and make victim drink ethanol again (approx. 0.3 ml of a 40% alcoholic beverage/kg body weight/hour).
Immediate Medical Attention
Immediately call in physician. Call a physician immediately. Call in ophthalmologist. Call a doctor immediately.
Medical Treatment
Make victim drink ethanol (e.g. 1 drinking glass of a 40% alcoholic beverage). Call a doctor immediately (mention methanol ingestion). Only in exceptional cases, if no medical care is available within one hour, induce vomiting (only in fully conscious persons) and make victim drink ethanol again (approx. 0.3 ml of a 40% alcoholic beverage/kg body weight/hour).
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Water, Foam, Carbon dioxide (CO2), Dry powder
For this substance/mixture no limitations of extinguishing agents are given.
Combustible. Development of hazardous combustion gases or vapours possible in the event of fire. Vapours are heavier than air and may spread along floors. Forms explosive mixtures with air at ambient temperatures. Pay attention to flashback.
Remove container from danger zone and cool with water.
Firefighter Protection
Stay in danger area only with self-contained breathing apparatus. Prevent skin contact by keeping a safe distance or by wearing suitable protective clothing.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Do not breathe vapours, aerosols. Avoid substance contact. Ensure adequate ventilation. Keep away from heat and sources of ignition. Evacuate the danger area, observe emergency procedures, consult an expert.
Do not let product enter drains. Risk of explosion.
Take up carefully with liquid-absorbent material (e.g. Chemizorb®). Dispose of properly. Clean up affected area.
Materials: liquid-absorbent material (e.g. Chemizorb®)

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Work under hood. Do not inhale substance/mixture. Avoid generation of vapours/aerosols. Observe label precautions.
Keep container tightly closed in a dry and well-ventilated place. Keep away from heat and sources of ignition. Keep locked up or in an area accessible only to qualified or authorised persons.
Immediately change contaminated clothing. Apply preventive skin protection. Wash hands and face after working with substance.
Keep away from open flames, hot surfaces and sources of ignition. Take precautionary measures against static discharge.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Technical measures and appropriate working operations should be given priority over the use of personal protective equipment. See section 7.1.
full contact: Glove material: butyl-rubber, Glove thickness: 0,7 mm, Break through time: > 480 min; splash contact: Glove material: Viton (R), Glove thickness: 0,70 mm, Break through time: > 120 min. The protective gloves to be used must comply with the specifications of EC Directive 89/686/EEC and the related standard EN374, for example KCL 898 Butoject® (full contact), KCL 890 Vitoject® (splash contact).
Safety glasses
required when vapours/aerosols are generated. Recommended Filter type: Filter AX (EN 371). The entrepreneur has to ensure that maintenance, cleaning and testing of respiratory protective devices are carried out according to the instructions of the producer. These measures have to be properly documented.
Flame retardant antistatic protective clothing.
Do not let product enter drains. Risk of explosion.
