* Zinc Cyanide is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, DEP, HHAG, NFPA and EPA. ... drums or other storage containers to process containers. Good WORK PRACTICES can help to reduce hazardous exposures. The following work practices are recommended:
The amount of zinc oxide equivalent to the zinc cyanide is equal to 75 g/l x 0.7 = 52.5 g/l. The use of this amount of zinc oxide would liberate an equal amount of sodium hydroxide.
cyanide and zinc oxide; or using caustic, sodium cyanide and zinc cyanide. Option A is labor-intensive, but material costs are low. Caution must be exercised with this option as the reaction is highly exothermic (more than 250°F). Option B has higher material costs, but is less labor-intensive and faster. Process steps. Soak alkaline cleaning
ZINC CYANIDE is decomposed by acids to give off hydrogen cyanide, a flammable poisonous gas. Tends to explosive instability. Capable of violent oxidation under certain condition; fusion with metal chlorates, perchlorates, nitrates or nitrites can cause explosions [Bretherick, 1979 p. 101].
