EXPOSURE
AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION

    		• Local exhaust or breathing protection.
    		Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED!
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
  • EYES

    		• Safety goggles, 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

    		• Do not eat, drink, or smoke during work.
    		Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P3 filter respirator for toxic particles).
    		Separated from strong oxidants.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     Reacts with nitro derivatives and strong oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: ppm; mg/m3 A2 (ACGIH 1997).
    MAK: TRK List 0.002 mg/m3; (1996)


    		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 can be reached very quickly on evaporation of this substance at 20░C.

    EFFECTS OF SHORT-TERM EXPOSURE:

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     This substance is probably carcinogenic to humans. May cause genetic damage in humans. May cause reproductive toxicity in humans.
