Emergency First Aid Measures
Critical first aid procedures for chemical exposure incidents and medical emergencies
🫁 Inhalation Exposure
Provide fresh air. In all cases of doubt, or when symptoms persist, seek medical advice.
🖐️ Skin Contact
After contact with skin, wash immediately with plenty of water. Immediate medical treatment required because corrosive injuries that are not treated are hard to cure.
Symptoms:
Corrosion
👁️ Eye Contact
In case of contact with eyes flush immediately with plenty of flowing water for 10 to 15 minutes holding eyelids apart and consult an ophthalmologist. Protect uninjured eye.
Symptoms:
Risk of blindness, Risk of serious damage to eyes
🍽️ Ingestion/Swallowing
Rinse mouth immediately and drink plenty of water. Call a physician immediately. If swallowed danger of perforation of the esophagus and the stomach (strong corrosive effects).
Symptoms:
danger of perforation of the esophagus and the stomach (strong corrosive effects), Gastric perforation
🚨 Immediate Medical Attention Required
Immediate medical treatment required because corrosive injuries that are not treated are hard to cure. Call a physician immediately.

Exposure Controls & Personal Protective Equipment (PPE)
Occupational exposure limits, engineering controls, and required safety equipment
🧤 Hand Protection
Wear suitable gloves. Chemical protection gloves are suitable, which are tested according to EN 374. Check leak-tightness/impermeability prior to use. For special purposes, it is recommended to check the resistance to chemicals of the protective gloves mentioned above together with the supplier of these gloves. The times are approximate values from measurements at 22 ° C and permanent contact. Increased temperatures due to heated substances, body heat etc. and a reduction of the effective layer thickness by stretching can lead to a considerable reduction of the breakthrough time. If in doubt, contact manufacturer. At an approx. 1.5 times larger / smaller layer thickness, the respective breakthrough time is doubled / halved. The data apply only to the pure substance. When transferred to substance mixtures, they may only be considered as a guide. Type of material: NBR (Nitrile rubber), Material thickness: >0,3 mm, Breakthrough times of the glove material: >480 minutes (permeation: level 6).
👁️ Eye Protection
Use safety goggle with side protection. Wear face protection.
😷 Respiratory Protection
Respiratory protection necessary at: Dust formation. Particulate filter device (EN 143). P1 (filters at least 80 % of airborne particles, colour code: White).
🦺 Skin/Body Protection
Take recovery periods for skin regeneration. Preventive skin protection (barrier creams/ointments) is recommended.
🌍 Environmental Exposure Controls
Keep away from drains, surface and ground water.
