4.1 Description of necessary first-aid measures

General advice

Consult a physician. Show this safety data sheet to the doctor in attendance.

If inhaled

If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.

In case of skin contact

Rinse skin with plenty of water or shower.

In case of eye contact

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

If swallowed

Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention .

4.2 Most important symptoms/effects, acute and delayed

Exposure Routes: inhalation, ingestion, skin and/or eye contact Symptoms: Irritation eyes, skin, respiratory system; sensitization dermatitis; lassitude (weakness, exhaustion), tremor, restlessness, headache, dizziness; metallic taste; peripheral neuropathy; liver damage Target Organs: Eyes, skin, respiratory system, central nervous system, peripheral nervous system, liver (NIOSH, 2016)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

/For acute disulfiram overdose/; Maintain an open airway and assist ventilation if necessary. Treat coma and seizures if they occur. /For disulfiram-ethanol interaction/; maintain an open airway and assist ventilations if necessary. Treat hypotension with supine position and intravenous fluids (e.g., saline), and treat vomiting with metoclopramide. If a pressor agent is needed, a direct-acting agent such as norepinephrine is preferred over indirect-acting drugs such as dopamine. Administer benzodiazepine anxiolytics (e.g., diazepam or lorazepam) and reassurance as needed. There is no specific antidote.

7.Handling and storage

7.1 Precautions for safe handling

Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

7.2 Conditions for safe storage, including any incompatibilities

Separated from strong oxidants.Commercially available disulfiram tablets should be protected from light and stored in tight, light-resistant containers at a temperature less than 40°C preferably between 15-30°C. Oral suspensions of disulfiram have been prepared extemporaneously from commercially available tablets of the drug. A suspension of 1% disulfiram, 1/4% methylcellulose, and 10% Tang /breakfast drink/ in distilled water has been reported to be stable for up to 6 months if refrigerated at 2-8°C and protected from light.

12.Ecological information

12.1 Toxicity

• Toxicity to fish: LC50 Oncorhynchus mykiss (Rainbow trout, donaldson trout; early life stage (fertilized egg to fry)) 9.0 ug/L/60 days (95% confidence interval: 8.0-10.0 ug/L); renewal /formulated product
• Toxicity to daphnia and other aquatic invertebrates: LC50 Daphnia magna 0.12 mg/L/48 hr /Conditions of bioassay not specified in source examined
• Toxicity to algae: no data available
• Toxicity to microorganisms: no data available

12.2 Persistence and degradability

no data available

12.3 Bioaccumulative potential

An estimated BCF of 280 was calculated for disulfiram(SRC), using a log Kow of 3.88(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC).

12.4 Mobility in soil

The Koc of disulfiram is estimated as 3,100(SRC), using a log Kow of 3.88(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that disulfiram is expected to have slight mobility in soil.

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
