Nitric acid violently oxidized a thiocyanate solution [Bretherick 1979 p. 121]. Caution should be exercised in treating a thiocyanate with an oxidizing agent such as a peroxide or chlorate as such mixtures have been known to explode. Special Hazards of Combustion Products: Irritating oxides of sulfur and nitrogen may form in fire (USCG, 1999). Carbonyl sulfide is produced in a violent reaction by the mixture of sulfuric acid and sodium thiocyanate.

Separated from acids, bases, oxidants and food and feedstuffs. Dry. Well closed.

Stable. Incompatible with acids, strong bases. May decompose on exposure to light. Contact with acid liberates highly toxic gas.

Fire Extinguishing Agents: Use extinguishing agents appropriate for the surrounding fire. (USCG, 1999)|In case of fire in the surroundings, use appropriate extinguishing media.

Rubber or plastic gloves; standard goggles; rubber or plastic apron (USCG, 1999)|Rubber or plastic gloves; splash-proof goggles; rubber or plastic apron. (USCG, 1999)

Sweep spilled substance into covered containers. Carefully collect remainder. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance.

Separated from acids, bases, oxidants and food and feedstuffs. Dry. Well closed.

A harmful concentration of airborne particles can be reached quickly when dispersed.

The substance may cause effects on the central nervous system. This may result in excitement and convulsions.

The substance may have effects on the central nervous system and thyroid. This may result in impaired functions and hypothyroidism.

PREVENT DISPERSION OF DUST!

Use local exhaust or breathing protection.

Protective gloves.

Wear safety goggles or eye protection in combination with breathing protection.

Inhalation of dust causes irritation of nose and throat. Ingestion of large doses causes vomiting, extreme cerebral excitement, convulsions, and death in 10-48 hrs.; chronic poisoning can cause flu-like symptoms, skin rashes, weakness, fatigue, vertigo, nausea, vomiting, diarrhea, confusion. Contact with eyes causes irritation. Prolonged contact with skin may produce various skin eruptions, dizziness, cramps, nausea, and mild to severe disturbance of the nervous system. (USCG, 1999)|Intensity of effects will vary with concentration of the solution. Inhalation of vapor causes irritation of nose and throat. Ingestion of large doses causes vomiting, extreme cerebral excitement, convulsions, and death in 10-48 hrs.; chronic poisoning can cause flu-like symptoms, skin rashes, weakness, fatigue, vertigo, nausea, vomiting, diarrhea, confusion. Contact with eyes causes irritation. Prolonged contact with skin may produce various skin eruptions, dizziness, cramps, nausea, and mild to severe disturbance of the nervous system. (USCG, 1999)

INHALATION: move to fresh air; if exposure has been great, get medical attention. INGESTION: consult physician; hemodialysis is recommended as the treatment of choice. EYES or SKIN: flush with water for 15 min. (USCG, 1999)|Call for medical aid. INHALATION: Move to fresh air. INGESTION: Consult physician; hemodialysis is recommended as the treatment of choice. EYES or SKIN: Flush with water for 15 min. (USCG, 1999)

Fresh air, rest.

Remove contaminated clothes. Rinse and then wash skin with water and soap.

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