First Aid Measures
Emergency procedures for chemical exposure incidents
Move to fresh air. If symptoms persist, seek medical advice.
Symptoms: Irritation, coughing, shortness of breath, chest tightness.
Rinse with running water and soap. Obtain medical attention if irritation persists.
Symptoms: Prolonged or repeated contact may cause skin irritation.
Rinse immediately with plenty of running water (for 10 minutes), seek medical attention from a specialist.
Symptoms: Irritation, conjunctivitis.
Rinse mouth, drink 1-2 glasses of water, do not induce vomiting, consult a doctor.
Immediate Medical Attention
See section: Description of first aid measures
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Carbon dioxide, foam, powder
None known
In the event of a fire, carbon monoxide (CO) and carbon dioxide (CO2) can be released.
In case of fire, keep containers cool with water spray.
Firefighter Protection
Wear self-contained breathing apparatus and full protective clothing, such as turn-out gear.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Avoid skin and eye contact. Ensure adequate ventilation.
For small spills wipe up with paper towel and place in container for disposal.
For large spills absorb onto inert absorbent material and place in sealed container for disposal.
Do not let product enter drains.
wipe up with paper towel (small spills), absorb onto inert absorbent material (large spills)
Materials: paper towel, inert absorbent material

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Use only in well-ventilated areas. Prolonged or repeated skin contact should be avoided to minimise any risk of sensitisation.
Store in original containers at 8-21°C (46.4-69.8°F) and do not return residual materials to containers as contamination may reduce the shelf life of the bulk product.
Wash hands before work breaks and after finishing work. Do not eat, drink or smoke while working. Good industrial hygiene practices should be observed.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Use only in well-ventilated areas.
Chemical-resistant protective gloves (EN 374). Suitable materials for short-term contact or splashes (recommended: at least protection index 2, corresponding to > 30 minutes permeation time as per EN 374): nitrile rubber (NBR; >= 0.4 mm thickness). Suitable materials for longer, direct contact (recommended: protection index 6, corresponding to > 480 minutes permeation time as per EN 374): nitrile rubber (NBR; >= 0.4 mm thickness). This information is based on literature references and on information provided by glove manufacturers, or is derived by analogy with similar substances. Please note that in practice the working life of chemical-resistant protective gloves may be considerably shorter than the permeation time determined in accordance with EN 374 as a result of the many influencing factors (e.g. temperature). If signs of wear and tear are noticed then the gloves should be replaced.
Safety glasses with sideshields or chemical safety goggles should be worn if there is a risk of splashing.
An approved mask or respirator fitted with an organic vapour cartridge should be worn if the product is used in a poorly ventilated area. Filter type: A
Wear suitable protective clothing.
