    Wear safety glasses that have side-shields that conform to EN 166. Use tested and approved eye protection equipment under appropriate government standards such as EN 166 (EU) or NIOSH (US).

    2. 2,5-Dichloropyrazine(19745-07-4) Engineering controls

    • Provide adequate ventilation in places where there is the formation of dust. Install fume hoods and local exhaust ventilation.
    • Install eyewash stations and safety showers to help in flushing of the chemical substance in case of body contact and in putting off fire from clothes in case a fire occurs.

    3. First aid measures

    If inhaled

    Get the victim out of the area of contamination to a place that has fresh air. Let them lie in a position that can allow them to breathe comfortably. If they are not breathing, trained personnel should administer oxygen or give them artificial respiration.

    If ingested

    Contact a doctor or a poison center immediately. Induce vomiting only if advised by medical personnel to do so. You should not give an unconscious victim anything by mouth.

    In case of eye contact

    Flush your eyes with plenty of water for a minimum of 20 minutes. Remove contact lenses if wearing any and clean under your eyelids. If burning or pain sensation persists, see a physician.
