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.
Wear appropriate protective gloves, clothing and goggles.
Organic vapor acid gas canister; available in the cab or cockpit and worn while exiting.
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.
Unstable in dry, crystalline form decomposed by light, moisture and heat. Stable as an aqueous solution.
Incompatible with acids, peroxides, and acid halides.
Self-contained breathing apparatus, rubber gloves, hats, suits and boots must be worn. Highly toxic fumes are imminent.
If water solution boils, poisonous hydrogen sulfide and highly flammable carbon disulfide vapors form.
Fire may produce irritating, corrosive and/or toxic gases.
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.
Nausea, vomiting and diarrhea may occur.
Respiratory failure, requiring ventilatory support, has been reported following ingestions.
Exposure to dusts, sprays, solutions, wettable powder suspensions or emulsions of these agents may lead to skin and mucous membrane irritation.
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. Oxygen therapy is effective in relieving the distress of antabuse-like reactions rarely associated with exposure to thiram and possibly the mbdt-carb compounds. No specific antidotes are available for poisoning by these compounds. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
Remove to fresh air; administer artificial respiration and oxygen, if indicated.
Wash thoroughly with soap and water.
Immediately flush with running water for at least 20 minutes.
