Emergency First Aid Measures
Critical first aid procedures for chemical exposure incidents and medical emergencies
🫁 Inhalation Exposure
Supply fresh air. In case of breathing difficulties or respiratory arrest, initiate artificial respiration. Seek immediate medical advice.
Symptoms:
Breathing difficulty, respiratory arrest
🖐️ Skin Contact
Flush contaminated skijn with soap and plenty of water. Consult a doctor if symptoms persist.
Symptoms:
Dermatitis (skin drying)
👁️ Eye Contact
Rinse out opened eye for several minutes under running water. Remove contact lenses. Continue rinsing. Seek immediate medical advice.
🍽️ Ingestion/Swallowing
Rinse mouth thoroughly with water. Make vicitim drink water (two glasses at most). Do not induce vomiting - aspiration hazard. Call a doctor immediately.
Symptoms:
Risk of aspiration, Gastric or intestinal disorders, Nausea
🚨 Immediate Medical Attention Required
Seek immediate medical advice (inhalation, eye contact). Call a doctor immediately (swallowing). Later observation for pneumonia and pulmonary oedema. Give Glucocorticoid-Aerosol in case of lung irritation. If necessary oxygen respiration treatment. Monitor circulation, possible shock treatment.
Medical Treatment
Give Glucocorticoid-Aerosol in case of lung irritation. If necessary oxygen respiration treatment. Monitor circulation, possible shock treatment.

🧤 Hand 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. NBR: acrylonitrile-butadiene rubber Material thickness > 0.4 mm Penetration time of glove material The exact break through time has to be found out by the manufacturer of the protective gloves and has to be observed. level 6 for application > 480 min
👁️ Eye Protection
Tightly sealed goggles
😷 Respiratory Protection
Not required.
🦺 Skin/Body Protection
Protective work clothing (e. g. safety shoes EN ISO 20345, long-sleeved protective working garments).
