Hazards and Protection.
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.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Cover with plastic sheet to prevent spreading. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.
Stability
Unstable in alkaline media and strongly acidic media.

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.
   Ingestion
Nausea, vomiting, and diarrhea may follow ingestion.
   Inhalation
Aspiration of insecticide containing petroleum distillate may result in pneumonitis.
   Skin
Extensive contact results in dermal irritation.
   Eyes
See Inhalation.

First aid
 
   Ingestion
Induced vomiting is not recommended because of the potential for cns depression and seizures. Consider washing of the stomach with repeated injections of water after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 60 minutes). Administer charcoal as a slurry.
   Inhalation
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
   Skin
Remove contaminated clothing. Wash skin and hair thoroughly; do two soap and water washings. Leather absorbs pesticides. Hence, leather should not be worn in the presence of pesticides and all contaminated leather should be discarded.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
