First Aid Measures
【Ingestion】DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician.
【Inhalation】IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used.
【Skin】IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
【Eyes】First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

Handling and Storage
【Storage】Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
【Handling】All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification
【Inhalation】Aspiration of insecticide containing petroleum distillate may result in pneumonitis.
【Skin】Extensive contact results in dermal irritation.
【Ingestion】Nausea, vomiting, and diarrhea may follow ingestion.
【EC Risk Phrase】R 22 36 50/53
【EC Safety Phrase】S 26 60 61
【UN (DOT)】3077

Exposure Controls/Personal Protection
【Personal Protection】Chemical splash ggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
【Respirators】Wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter.
【Exposure Effects】CNS excitation, seizures, tremor, ataxia, agitation, nervousness, and amnesia may occur. Kelthane, perthane, methoxychlor, and hexachlorobenzene have little CNS toxicity; in extreme overdose CNS depression may occur. Organochlorine pesticides such as DDT pass through the placenta, with an average level in the newborn blood reaching around a third of that in maternal blood. They can also be found in breast milk. Excessive absorption of kepone (chlordecone) has depressed sperm counts and sperm motility in exposed workers.
【Poison Class】4

Fire Fighting Measures
【Fire Fighting】Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. A water spray may also be used.
【Fire Potential】This material is probably combustible.

Accidental Release Measures
【Small spills/leaks】Should a spill occur while you are handling this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with 60-70% ethanol and transfer the dampened material to a suitable container. Use absorbent paper dampened with 60-70% ethanol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

Stability and Reactivity
【Incompatibilities】Incompatible with strong oxidizing agents and strong bases.
【Stability】Slight volatility.
