EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION

    		• Ventilation (not if powder).
    		Refer for medical attention.
  • SKIN

    		• Protective gloves. Protective clothing.
    		Rinse and then wash skin with water and soap.
  • EYES
    		• Redness.
    		Safety spectacles.
    		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. Wash hands before eating.
    		Rinse mouth. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Do NOT wash away into sewer. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P2 filter respirator for harmful particles).
    		Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS CRYSTALS.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic fumes including hydrogen chloride, nitrogen oxides.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: ppm; 5 mg/m3 (ACGIH 1993-1993).
    OSHA PEL: none
    NIOSH REL: TWA 5 mg/m3
    NIOSH IDLH: No data


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

    INHALATION RISK:
     A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the liver and kidneys. This substance is possibly carcinogenic to humans.
    PHYSICAL
    PROPERTIES
    Decomposes below boiling point: see Notes
    Melting point: 173-177°C
    Relative density (water = 1): 1.2
    		 Solubility in water, g/100 ml at 25°C: none
    Vapour pressure, Pa at 20°C: very low
    Octanol/water partition coefficient as log Pow: 2.34
    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to plants, soil- and water organisms.
