Potassium Cyanide

CAS RN:151-50-8

Other Preventive Measures

... Attention to ... Ventilation is necessary. ... Because of low permissible exposure level for hydrogen cyanide, complete enclosure of process is recommended. ... Where an exposure exists, workers should be trained to recognize the odor ... & when this is detected, the work area should be evacuated immediately. /cyanides/
SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.
Eyewash facilities and emergency showers shall be provided in areas where contact with ... cyanide salts as either solids or solutions is likely. Work clothing which has been contaminated by absorption of, or contact with, cyanide shall be thoroughly laundered before it is worn again. /Hydrogen cyanide and cyanide salts/
If the clothing is to be laundered or otherwise cleaned to remove the cyanide, the person performing the operation should be informed of cyanide's hazardous properties. /Cyanides/
Two physician's treatment kits shall be immediately available to trained medical personnel at each plant where there is a potential for the release of, accidental or otherwise, or for contact with, hydrogen cyanide or cyanide salts. ... First-aid kits shall be immediately available at workplaces where there is potential for the release, accidental or otherwise, of hydrogen cyanide or a potential for exposure to cyanide salts. ... Pertinent medical records shall be maintained ... /SRP: for the duraton of employment plus 50 years [29 CFR 1910.1020]/ following the last exposure to hydrogen cyanide or cyanide salts. /Hydrogen cyanide and cyanide salts/
Persons who work with & around cyanide prepn should be given specific detailed instructions on management of cyanide poisoning. /cyanides/
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.
Food storage, preparation, and eating shall be prohibited in areas where hydrogen cyanide is used. Smoking and the carrying of tobacco and other smoking materials shall also be prohibited in these areas. Clean and sanitary lunchroom facilities, if provided, must be in non-exposure areas. ... Clothing-change and locker-room facilities shall be provided in a non-exposure area. Workers should be encouraged to shower after work and to change work clothing frequently. Showers and basin washing facilities shall be located in the locker-room area. /Hydrogen cyanide or cyanide salts/
The worker should immediately wash the skin when it becomes contaminated.
Work clothing that becomes wet or significantly contaminated should be removed and replaced.
Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises.
All containers ... Should be kept covered or in exhausted hood when not in use. Any process that may release hydrogen cyanide should be mechanically exhausted, with provision for higher rate during emergencies. Direct reading instruments for determination of hydrocyanic acid are available. /cyanides/
If material not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors. /Potassium cyanide solution/
If material not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Use water spray to knock-down vapors. Do not use water on material itself. /Potassium cyanide, solid/
Personnel protection: ... If contact with the material anticipated, wear appropriate chemical protective clothing. /Potassium cyanide, solid/
Personnel protection: Avoid breathing vapors. Keep upwind. ... Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water. /Potassium cyanide solution; potassium cyanide, solid/
