Hazards and Protection.
Keep in well ventilated area.
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.
Self-contained breathing apparatus must be worn. Rubber gloves, hats, suits and boots must be worn.
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.
Stable to concentrated and dil alkalis, mineral acids, high temperature and UV light. Low volatility; no loss of wt on exposure at 20 C for 17 hr resistant to hydrolysis by acid or alkali.
Dangerous when heated to decomposition, it emits highly toxic fumes of hydrogen chloride and sulfur oxides.
Self-contained breathing apparatus rubber gloves, hats, suits and boots must be worn. Highly toxic fumes are imminent.
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.
Nausea, vomiting, and diarrhea may follow ingestion.
Aspiration of insecticide containing petroleum distillate may result in pneumonitis.
Extensive contact results in dermal irritation.
Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.
If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.
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.
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.
