4. Safety and Handling

4.1 Exposure Standards and Regulations: Ammonium thiocyanate is an indirect food additive for use only as a component of adhesives. [21 CFR 175.105;

4.2 Other Preventative Measures: If material not on fire and not involved in fire: Keep material out of water sources and sewers. Build dikes to contain flow as necessary.
Personnel protection: Keep upwind. ... Avoid breathing vapors. Wash away any material which may have contacted the body with copious amounts of water or soap and water.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

4.3 Cleanup Methods: A waste solution containing ammonium thiocyanate from a coke oven is sprayed into a combustion furnace and converted to gypsum by air oxidation.
Environmental considerations: Water spill: Neutralize with dilute acid or removable strong acid. Add calcium hypochlorite. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Environmental considerations: Land spill: Dig a pit, pond, lagoon, or holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be contained with a flexible impermeable membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water.
Remove slowly into a large container of water. Add soda ash slightly by stirring. After 24 hr, decant or siphon into another container. Neutralize with 6M-HCl.

4.4 DisposalMethods: SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material=s impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

4.5 Fire Fighting Procedures: Extinguish with water.
If material on fire or involved in fire: Extingiush fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)
/During fire fighting/ wear goggles and self-contained breathing apparatus.

4.6 FirePotential: Solid may be combustible; soln is not flammable.

4.7 Formulations/Preparations: GRADES: Technical; CP; 50 to 60 % solution.
Usual grade is 98-99% pure.
Grades or Purity: Reagent; Technical, 50-65% soln in water
Amitrole-T (union carbide); radazone TL was a mixture of amitrole and ammonium thiocyanate
A technical crystal of 98% minimum assay with approximately 2 wt % maximum of water content is commercially available, as well as a 50-55 wt % aqueous solution. The latter is the predominant product.
Commercial products are 50-60% solution.

4.8 Protective Equipment and Clothing: Rubber or plastic gloves; rubber or plastic apron; standard goggles
Personnel protection: ... Wear boots, protective gloves, and goggles.

4.9 Reactivities and Incompatibilities: Incompatibilities: KClO3 and mixtures with Pb(NO3)2

4.10 Report: Reported in EPA TSCA Inventory. EPA Genetic Toxicology Program.

4.11 Skin, Eye, and Respiratory Irritations: Inhalation of dust causes irritation of nose and throat. ... Dust irritates eyes.
