First Aid Measures

Ingestion

Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.

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. 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.

Ingestion

May cause irritation of the digestive tract. May cause liver and kidney damage. May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and nausea. Advanced stages may cause collapse, unconsciousness, coma and possible death due to respiratory failure.

Inhalation

May cause respiratory tract irritation. May cause effects similar to those described for ingestion.

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.

Inhalation

Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid if cough or other symptoms appear.

Skin

Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.

Skin

May cause skin irritation. Prolonged and/or repeated contact may cause irritation and/or dermatitis.

Skin

Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists. Wash clothing before reuse.

Eyes

May cause eye irritation.

Eyes

Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. If irritation develops, get medical aid.

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.

Handling and Storage

Storage

Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.

Storage

Store in a cool, dry, well-ventilated area away from incompatible substances. Store in opaque, air-tight containers.

Handling

Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Do not get on skin or in eyes. Do not ingest or inhale. Store protected from light.

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.

Ingestion

Nausea, vomiting and diarrhea may occur.

Hazards

When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.

Exposure Controls/Personal Protection

Personal Protection

Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear impervious gloves. Clothing: Wear appropriate protective clothing to prevent skin exposure.

Personal Protection

Safety glasses, goggles, or faceshield; impervious gloves and apron.

Respirators

Use NIOSH/MSHA approved respirator appropriate for exposure of concern.

Respirators

Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.

Exposure Effects

Chronic exposure can lead to iodism characterized by salivation, nasal discharge, sneezing, conjunctivitis, fever, laryngitis, bronchitis, stomatitis, and skin rashes.

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.

Fire Fighting Measures

Flash Point

104

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 water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Extinguishing media: Use foam, dry chemical, or carbon dioxide. Use agent most appropriate to extinguish fire. Cool containers with flooding quantities of water until well after fire is out.

Fire Fighting

Wear self-contained breathing apparatus with a full facepiece operated in pressure-demand or other positive pressure mode when fighting fire.

Fire Potential

Combustible material: may burn but does not ignite readily.

Accidental Release Measures

Small spills/leaks

Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.

Small spills/leaks

Neutralize spill with sodium bicarbonate. Remove all sources of ignition. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Carefully scoop up and place into appropriate disposal container. Provide ventilation.
