FIRE FIGHTING
FIRE Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Alcohol-resistant foam, powder, carbon dioxide.
EXPLOSION Above 56C explosive vapour/air mixtures may be formed. Explosion hazard will depend on the solvent used or on the characteristics of the dust.
Above 56C closed system, ventilation.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS! STRICT HYGIENE!

  • INHALATION
  • (see Ingestion).
    Breathing protection.
    Fresh air, rest. Refer for medical attention.
  • SKIN
  • MAY BE ABSORBED!
    Protective gloves. Protective clothing.
    Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
  • Redness.
    Safety goggles or 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
  • Convulsions. Nausea. Vomiting.
    Do not eat, drink, or smoke during work.
    Do NOT induce vomiting. Rest. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    Separated from food and feedstuffs, strong bases. Cool. Dry.
    Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
    LIGHT YELLOW TO AMBER VISCOUS LIQUID.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance decomposes on heating and/or on burning and on contact with bases producing toxic fumes: chlorine fumes, hydrogen chloride, phosgene. Attacks plastic, rubber and coating.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: ppm; 0.5 mg/m3 (as TWA) (skin) (ACGIH 1991-1992).
    PDK: 0.01 mg/m3 C (USSR 1977).


    ROUTES OF EXPOSURE:
    The substance can be absorbed into the body by inhalation of dusts from powder concentrates, through the skin especially from liquid formulations, and by ingestion.

    INHALATION RISK:
    Evaporation at 20C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed.

    EFFECTS OF SHORT-TERM EXPOSURE:
    Inhalation of dust may cause irritation. Exposure at high levels may result in disorientation, tremors, convulsions, respiratory failure and death. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    This substance is possibly carcinogenic to humans.
    PHYSICAL
    PROPERTIES
    Boiling point at 1.33 kPa: 175C
    Relative density (water = 1): 1.59-1.63
    Solubility in water: None
    Vapour pressure, Pa at 25C: 0.0013
    Octanol/water partition coefficient as log Pow: 2.78
    ENVIRONMENTAL
    DATA
    Chlordane is persistent and rather immobile in soil. This substance may be hazardous to the environment; special attention should be given to fish in tropical areas. It is strongly advised not to let the chemical enter into the environment.
    NOTES
    The commercial product (technical chlordane) is a mixture containing 60 to 75% of the pure compound and 25 to 40% of related compounds. The chlorine content is 64-67%. Other melting points: cis-isomer: 106-107C; trans-isomer: 104-105C. All uses of this substance are increasingly restricted. Safe and equally effective alternatives should be prepared. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Aspon Chlordane, Belt, Corodane, Niran, Velsicol 1068, Toxichlor, Octachlor, Ortho-klor, Synklor, Topiclor, Toxichlor are trade names. Also consult ICSC # 0743 on heptachlor.
