Smoke alarms significantly reduce the incidence of serious smoke inhalation injury. Workplaces using cyanides should have engineering controls in place to avoid inadvertent exposures. Workers should be provided with personal protective equipment and training; they should be instructed to avoid contact between cyanide salts and mineral acids or other compounds with low pH.

Patients receiving sodium nitroprusside at high doses or for more than 5 days should have monitoring of blood cyanide or thiocyanate concentrations. Alternatively, these patients can be treated prophylactically with sodium thiosulfate or hydroxocobalamin to reduce the risk of iatrogenic cyanide poisoning.
