First Aid Measures
Emergency procedures for chemical exposure incidents
Move to fresh air. Consult a physician after significant exposure.
Take off contaminated clothing and shoes immediately. Wash off with soap and plenty of water. If symptoms persist, call a physician.
Symptoms: allergic skin reaction
Remove contact lenses. Keep eye wide open while rinsing. If eye irritation persists, consult a specialist.
Symptoms: eye irritation
Do not induce vomiting without medical advice. Rinse mouth with water. Do not give milk or alcoholic beverages. Never give anything by mouth to an unconscious person.
Medical Treatment
Treat symptomatically.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
In case of fire, use water/water spray/water jet/carbon dioxide/sand/foam/alcohol resistant foam/chemical powder for extinction.
Standard procedure for chemical fires.
Firefighter Protection
In the event of fire, wear self-contained breathing apparatus.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Use personal protective equipment. Deny access to unprotected persons.
Do not flush into surface water or sanitary sewer system.
Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust). Keep in suitable, closed containers for disposal.
Materials: inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust)

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Avoid exceeding the given occupational exposure limits (see section 8). Do not get in eyes, on skin, or on clothing. For personal protection see section 8. Persons with a history of skin sensitisation problems or asthma, allergies, chronic or recurrent respiratory disease should not be employed in any process in which this mixture is being used. Smoking, eating and drinking should be prohibited in the application area. Follow standard hygiene measures when handling chemical products
Keep container tightly closed in a dry and well-ventilated place. Store in accordance with local regulations.
Handle in accordance with good industrial hygiene and safety practice. When using do not eat or drink. When using do not smoke. Wash hands before breaks and at the end of workday.
Normal measures for preventive fire protection.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Maintain air concentrations below occupational exposure standards. Ensure adequate ventilation, especially in confined areas.
Chemical-resistant, impervious gloves complying with an approved standard must be worn at all times when handling chemical products. Reference number EN 374. Follow manufacturer specifications. Suitable for short time use or protection against splashes: Butyl rubber/nitrile rubber gloves (> 0,1 mm) Contaminated gloves should be removed. Suitable for permanent exposure: Viton gloves (0.4 mm), breakthrough time >30 min.
Safety glasses with side-shields conforming to EN166 Eye wash bottle with pure water
In case of inadequate ventilation wear respiratory protection. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product and the safe working limits of the selected respirator. organic vapor filter (Type A) A1: < 1000 ppm; A2: < 5000 ppm; A3: < 10000 ppm Ensure adequate ventilation. This can be achieved by local exhaust extraction or by general ventilation. (EN 689 - Methods for determining inhalation exposure). This applies in particular to the mixing / stirring area. In case this is not sufficent to keep the concentrations under the occupational exposure limits then respiration protection measures must be used.
Protective clothing (e.g. Safety shoes acc. to EN ISO 20345, long-sleeved working clothing, long trousers). Rubber aprons and protective boots are additionaly recommended for mixing and stirring work.
Do not flush into surface water or sanitary sewer system.
