First Aid Measures

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.

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.

Handling and Storage

Storage

Keep container tightly closed. Keep in a cool, dry location. Store only with compatible chemicals.

Handling

Avoid contact with skin, eyes and clothing. Do not breathe vapors. Contact lenses shouldn’t be worn in the laboratory. Persons not perly trained shouldn’t handle this chemical or its container.

Hazards Identification

Inhalation

Respiratory failure, requiring ventilatory support, has been reported following ingestions.

Skin

Harmful/fatal if absorbed.

Ingestion

Fatal if ingested.

Exposure Controls/Personal Protection

Personal 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

Use OSHA/MSHA approved respirator.

Exposure Effects

Suspected carcinogen.

Fire Fighting Measures

Flash Point

166

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.

Accidental Release Measures

Small spills/leaks

Evacuate the area. Wear SCBA, rubber boots and gloves. Cover with dry lime or soda ash. Pickup and keep in a closed contaner for waste disposal. Wash area until material pickup is complete.

Stability and Reactivity

Stability

Stable under acid and moderately alkaline conditions.

Incompatibilities

Strong oxidizing agents.
