Irritation, coughing, shortness of breath, chest tightness.
🖐️ Skin Contact
Rinse with running water and soap. Obtain medical attention if irritation persists.
Symptoms:
Rash, Urticaria.
👁️ Eye Contact
Rinse immediately with plenty of running water (for 10 minutes), seek medical attention from a specialist.
Symptoms:
Irritation, conjunctivitis.
🍽️ Ingestion/Swallowing
Rinse mouth, drink 1-2 glasses of water, do not induce vomiting, consult a doctor.

Exposure Controls & Personal Protective Equipment (PPE)
Occupational exposure limits, engineering controls, and required safety equipment
🏭 Engineering Controls
Ensure good ventilation/extraction.
🧤 Hand Protection
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.
👁️ Eye Protection
Safety glasses with sideshields or chemical safety goggles should be worn if there is a risk of splashing. Protective eye equipment should conform to EN166.
😷 Respiratory Protection
Ensure adequate ventilation. 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 (EN 14387)
🦺 Skin/Body Protection
Wear suitable protective clothing. Protective clothing should conform to EN 14605 for liquid splashes or to EN 13982 for dusts.
