| [Fire Fighting] Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Keep run-off water out of sewers and water sources. | |
| [Fire Potential] Non-Combustible | |
| [Ingestion] Ipecac-induced vomiting is not recommended because of the potential for cns depression and seizures. Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Intravenous fluids may be useful in restoring extracellular fluid volume following severe vomiting and diarrhea. | |
| [Inhalation] Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. | |
| [Skin] Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. | |
| [Eyes] Immediately flush with running water for at least 20 minutes. | |
| [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] Respiratory failure, requiring ventilatory support, has been reported following ingestions. | |
| [Skin] Exposure to dusts, sprays, solutions, wettable powder suspensions or emulsions of these agents may lead to skin and mucous membrane irritation. | |
| [Eyes] See Inhalation. | |
| [Ingestion] Nausea, vomiting and diarrhea may occur. | |
| [UN (DOT)] 2771 | |
| [Personal Protection] Clothing and equipment should be consistent with good pesticide handling. For those engaged in spraying, eye protective equipment and respiratory protected equipment may well be essential. | |
| [Respirators] Wear positive pressure self-contained breathing apparatus (SCBA). | |
| [Exposure Effects] Exposure to thiram or mbdt-carb (based on animal studies) may cause weakness, ataxia, ascending paralysis and hypothermia. Peripheral neuropathy (pain, numbness and weakness of the extremities) has been noted following exposure to thiuram (the ethyl analog of thiram). No adverse reproductive effects (testicular parameters) in male mice were observed following methyl thiophanate doses up to 1000 mg/kg orally for 5 consecutive days (Traina et al, 1998). Maternal toxicity was evident in female rats. | |
| [Poison Class] 2 | |

| [Small spills/leaks] Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Do not use water. Attempt to stop leak if without undue personnel hazard. Apply water spray or mist to knock down vapors. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Absorb bulk liquid with fly ash, cement powder, or commercial sorbents. Water spill: Remove trapped material with suction hoses. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates. | |
