First Aid Measures

Ingestion
Seek medical assistance.
Inhalation
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used.
Skin
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
Eyes
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

Handling and Storage

Storage
Aspor and tiezene must be stored in their sealed original containers, in well-aired, dry storage areas or in shaded places. Do not allow storage temperature above 25 to 30 C. Stack containers to ensure air circulation throughout stacks, including bottom and interiors of piles.
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.

Hazards Identification

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.

Exposure Controls/Personal Protection

Personal Protection
Personal protective equipment should be issued to workers engaged in prodn of carbamates or in their agricultural use, in particular eye protections and respirators to those who spray crops.
Respirators
Wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter.
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
4

Fire Fighting Measures

Flash Point
90
Autoignition
149
Fire Fighting
Fires involving this compound should be controlled with a dry chemical, carbon dioxide or Halon extinguisher.
Fire Potential
Non-Combustible

Accidental Release Measures

Small spills/leaks
If you spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then dampen the solid spill material with toluene, then transfer the dampened material to a suitable container. Use absorbent paper dampened with toluene to pick up any remaining material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent-wash all contaminated surfaces with toluene followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

Stability and Reactivity

Incompatibilities
Incompatible with acids, peroxides, and acid halides.
Stability
Unstable to light, moisture and heat on prolonged storage. Terminal stability (40 C), 1-5% degradation after one month. Non-volatile under normal field conditions. Half-life of 38.1 Days in aqueous media at pH 9.
Decomposition
Decomposes at 157 C without melting. Zineb decomposes on storage primarily due to exposure to moisture. Products of the decomposition were identified as ethylenethiuram monosulfide, zinc sulfide, carbon disulfide and ethylenethiourea. Decomposes before melting. Decomposes gradually, accelerated by exposure to moisture, heat or air. When heated to decomposition it emits very toxic fumes of nitroxide, zinc oxide and sulfoxides.
Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
