| [Fire Fighting] Self-contained breathing apparatus rubber gloves, hats, suits and boots must be worn. Highly toxic fumes are imminent. | |
| [Ingestion] 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. | |
| [Inhalation] 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. | |
| [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. | |
| [Storage] Keep in well ventilated area. | |
| [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. | |
| [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. | |
| [Personal Protection] Self-contained breathing apparatus must be worn. Rubber gloves, hats, suits and boots must be worn. | |
| [Respirators] Use NIOSH/MSHA approved respirator appropriate for exposure of concern. | |
| [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. | |
