Hazards and Protection.
Storage
Keep in a cool dry location in a sealed container.
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
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
Respirators
NIOSH/MSHA approved dust mask.
Small spills/leaks
Sweep up. Wash surfaces with soap and water. Transfer to a container for disposal.
Stability
Stable at normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents.
Decomposition
Oxides of sulfur, nitrogen, carbon and zinc.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.

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.
   Ingestion
Nausea, vomiting and diarrhea may occur.
   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.

First aid
 
   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 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 and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
   Eyes
If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention.
