EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
    		• Confusion, dizziness, nausea, vomiting, unconsciousness. remember to sequence
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest, and refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! See Inhalation.
    		Protective gloves, protective clothing.
    		Remove contaminated clothes, rinse and then wash skin with water and soap, and refer for medical attention.
  • EYES

    		• Safety spectacles, face shield, or eye protection in combination with breathing protection.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• See Inhalation.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth, give plenty of water to drink, and refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Collect leaking and spilled liquid in sealable containers as far as possible, absorb remaining liquid in sand or inert absorbent and remove to safe place, do NOT let this chemical enter the environment.
    		Keep in a well-ventilated room.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS TO YELLOW LIQUID , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     Upon heating, toxic fumes are formed.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 0.05 mg/m3 (as TWA); 0.2 mg/m3 (as STEL) (skin) (ACGIH 1992-1993)
    OSHA PEL: none
    NIOSH REL: TWA 0.05 mg/m3 ST 0.2 mg/m3 skin
    NIOSH IDLH: No data


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation and through the skin, and by ingestion.

    INHALATION RISK:
     A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance may cause effects on the central nervous system, including impairment of vision. Exposure may result in death.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the central nervous system (cholinesterase inhibition).
