FIRE FIGHTING
FIRE Not combustible. Liquid formulations containing organic solvents may be flammable.

In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION Explosion hazard will depend on the solvent used or on the characteristics of the dust.


EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN!

  • INHALATION
    		• (see Ingestion).
    		Ventilation (not if powder).
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! See Ingestion.
    		Protective gloves. Rubber boots.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
    		• Redness.
    		Safety goggles or face shield.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Convulsions. Dizziness. Headache. Nausea. Vomiting. Weakness.
    		Do not eat, drink, or smoke during work.
    		Do NOT induce vomiting. Rest. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into sealable containers. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Separated from food and feedstuffs. Cool. Dry.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS CRYSTALS.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic and corrosive fumes (chlorine fumes, hydrogen chloride). Reacts with oxidants, concentrated mineral acids, acid acatalysts, metals (copper, iron). Attacks metal due to the slow formation of hydrogen chloride in storage.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (as TWA): ppm; 0.25 mg/m3 (skin) (ACGIH 1991-1992).


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

    INHALATION RISK:
     Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance may cause effects on the central nervous system , resulting in convulsions. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may be found in the human placenta.
    PHYSICAL
    PROPERTIES
    Melting point: 175-176°C
    Relative density (water = 1): 1.62
    Solubility in water: None
    		Vapour pressure, Pa at 20°C: 0.0004
    Octanol/water partition coefficient as log Pow: 6.2
    ENVIRONMENTAL
    DATA
         		Dieldrin persists in the environment: 50% disappear after 4 to 7 years. This substance may be hazardous to the environment; special attention should be given to birds and water organisms. In the food chain important to humans, bioaccumulation takes place, specifically in aquatic organisms.
    NOTES
    Technical dieldrin (95%) consists of light tan flakes with a mild odour. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. The recommendations on this Card also apply to ICSC # 0774 (aldrin). Alvit, Octalox, Quintox, Illoxol, Panoram D-31, Dieldrite, Dorytox, Compound 497 are trade names.
