The coal used in the next step must be low in nitrogen to avoid the formation of cyanide. Compared to free cyanide, this sodium cyanate is less but still toxic. Although free cyanide breaks down rapidly when exposed to sunlight, the less toxic products, such as cyanates and thiocyanates, may persist in the environment for many years.
A method to prevent the overfilling of cyanide storage tanks (other than by direct observation and manual gauging rod) should be provided, such as an automatic level indicator, high- level alarm, or integrated tank and tanker valve-shutdown device.
