The CAK kit detects only cyanides, azides, sulfides and chromates. ChemSee now also offers home-users the ability to test their foods directly for Cyanide using the CN Detector.

Cyanides may be detected using conventional laboratory techniques and instruments. Unfortunately, these techniques require expensive and sophisticated instrumentation and highly trained personnel and the results are NOT obtained immediately. Since in real emergency situations such amenities may not be available, and a timely response is critical to save a person live, the value of the laboratory services is mainly in post mortem investigations. Since the poisoning mechanism of cyanides is based on the reaction of the free cyanide ion with metals, mainly iron and thus preventing the proper absorption and assimilation of oxygen, antidotes to cyanide poisoning utilize injecting relatively large amounts of metallic ions which rapidly and irreversibly react with the cyanide ion.
This process depletes the concentration of the cyanide ions in the blood and thus reduces the amount of cyanide available for reaction with the iron and deactivating it. The most important qualities of a good antidote for cyanide poisoning are:. One of the antidotes used today is hydroxocobalamin, a naturally available form of vitamin B This compound reacts with cyanide to form cyanocobalamin, which is eliminated safely by the kidneys.
The cyanide reacts with the cobalt in the hydroxocobalamin and thus consumed and becomes unavailable to react with the iron. An antidote kit based on this chemistry is sold under the brand name Cyanokit and was approved by the FDA in The most important mechanism which eliminates cyanide from the body involves the enzymatic conversion of the cyanide to the relatively non-toxic thiocyanate ion.
CNS This process is done by the mitochondrial enzyme rhodanese. Taking some sodium thiosulfate accelerates the detoxification by providing a readily-available source of sulfur to the rhodanese. Unfortunately, the thiosulfate depletes some of the minerals in the body. Inhalation of nitrites assists in overcoming breathing problems due to cyanide. Traditionally, many emergency kits used to contain ampules of amyl nitrite to help revive people who ingested cyanides or breathed carbon monoxide or cyanogen or hydrocyanic acid.
Since the amyl nitrite ampoules were diverted to other applications, many kits do not contain them any longer. Phone: Fax: E mail: ajattar appealingproducts. The main ones are: A. Added Info on Toxicity Measurements. The main industries that use cyanides are: The mining of gold from low-grade ores. The mining of silver from low grade silver ores. Signs and symptoms of cyanide poisoning include the following:.
Cardiovascular : decreased inotropy, bradycardia followed by reflex tachycardia, hypotension, and pulmonary edema; and. Survivors may suffer Parkinson's disease, ataxia, optic atrophy, and other neurological disorders.
Cyanide intoxication is largely a clinical diagnosis; however, several laboratory features are suggestive:. Cyanide blood levels are confirmatory, as results are not obtainable in time for initial diagnosis. There are some reports of use of rapid calorimetric paper test strips to confirm the presence of cyanide. Before cyanide antidote can be administered, the patient must be removed from the cyanide-laden area, clothing removed, and skin washed with soap and water.
If cyanide salts have been ingested, activated charcoal may prevent absorption from the gastrointestinal tract. There are 2 major modalities of treatment: the cyanide antidote kit and hydroxocobalamin. Although recovery from a chemical attack is rare, victims may survive sub-lethal exposures, whether from ingestion, smoke inhalation, or exposure to cyanide-containing industrial products, such as carpet.
Patients who are treated successfully for cyanide poisoning should be observed for development of long-term neuropsychiatric symptoms that are similar to symptoms experienced by survivors of cardiac arrest or carbon monoxide poisoning.

Is there a Treatment for Cyanide Poisoning? Anne Marie Helmenstine, Ph. Chemistry Expert. Helmenstine holds a Ph. She has taught science courses at the high school, college, and graduate levels. Accumulation of fluid in the lungs pulmonary edema may complicate severe intoxications.
Severe cyanide poisonings progress to stupor, coma, muscle spasms in which head, neck, and spine are arched backwards , convulsions seizures , fixed and dilated pupils, and death. The CNS is the most sensitive target organ of cyanide poisoning. Cardiovascular effects require higher cyanide doses than those necessary for CNS effects.
In serious poisonings, the skin is cold, clammy, and diaphoretic. Blue discoloration of the skin may be a late finding. Severe signs of oxygen deprivation in the absence of blue discoloration of the skin suggest cyanide poisoning.
Contact with the eyes can contribute to whole-body systemic toxicity. See Inhalation Exposure. Whole-body systemic toxicity can occur. Cardiovascular effects: palpitations. Respiratory effects: respiratory tract irritation, difficulty breathing or shortness of breath dyspnea , and transient increase in the rate and depth of breathing hyperpnea.
GI effects: nausea and vomiting emesis. Severe: CNS effects: coma, seizures, and dilated pupils mydriasis. Cardiovascular effects: shock, abnormal or disordered heart rhythms dysrhythmias , critically low blood pressure, and cardiac arrest.
Respiratory effects: abnormally rapid, followed by abnormally slow respirations; accumulation of fluid in the lungs pulmonary edema ; and respiratory arrest.
Eye effects: dilated pupils, inflammation of the surface of the eye, and temporary blindness. Absorption through the skin can contribute to whole-body systemic toxicity. Care should be taken during decontamination, because absorbed agent can be released from clothing and skin as a gas.
Your Incident Commander will provide you with decontaminants specific for the agent released or the agent believed to have been released. The warm zone should include two decontamination corridors. One decontamination corridor is used to enter the warm zone and the other for exiting the warm zone into the cold zone. The decontamination zone for exiting should be upwind and uphill from the zone used to enter. Decontamination area workers should wear appropriate PPE.
See the PPE section of this card for detailed information. A solution of detergent and water which should have a pH value of at least 8 but should not exceed a pH value of Soft brushes should be available to remove contamination from the PPE. Labeled, durable 6-mil polyethylene bags should be available for disposal of contaminated PPE. Always move in a downward motion from head to toe. Make sure to get into all areas, especially folds in the clothing.
Wash and rinse using cold or warm water until the contaminant is thoroughly removed. Place all PPE in labeled durable 6-mil polyethylene bags.
Remove all clothing at least down to their undergarments and place the clothing in a labeled durable 6-mil polyethylene bag. First Aid. Speed is critical. Avoid mouth-to-mouth resuscitation regardless of route of exposure. Avoid contact with vomitus, which may off-gas hydrogen cyanide.
In these cases, only administer sodium thiosulfate. The described administration of nitrites is based on a patient having normal hemoglobin levels. Below normal hemoglobin levels require titration of nitrites. A new ampule of amyl nitrite should be broken into a cloth every 3 minutes.
Discontinue use of amyl nitrite when sodium nitrite becomes available. Therefore, children should receive 0. Next, administer 0.
