NOTE! PREVENT DISPERSION OF DUST! STRICT HYGIENE!
General First Aid: IN ALL CASES CONSULT A DOCTOR!

Route of Exposure

Symptoms

First Aid

Inhalation Confusion. Convulsions. Headache. Shortness of breath. Sore throat. Unconsciousness. Weakness. Fresh air rest. No mouth-to-mouth artificial respiration. Administer oxygen by trained personnel. Refer for medical attention.
Skin MAY BE ABSORBED! Redness. Pain. (Further see Inhalation). Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain. (Further see Inhalation). First rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor.
Ingestion Burning sensation. Diarrhoea. Nausea. Vomiting. (See Inhalation). No mouth-to-mouth artificial respiration. Administer oxygen by trained personnel. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Wear protective gloves when inducing vomiting. Refer for medical attention. See Notes.
Notes for ICSC Information
The occupational exposure limit value should not be exceeded during any part of the working exposure. Depending on the degree of exposure periodic medical examination is suggested. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT take working clothes home. Never work alone in an area if hydrocyanic acid exposure is possible.
Symptoms of Sodium cyanide Exposure from Other Sources

-Irritating to skin, eyes, and respiratory system.
-Bitter, acrid, burning taste.
-Constriction or numbness in the throat. Salivation, nausea and vomiting are not unusual.
- Anxiety, confusion, vertigo, giddiness, and often a sensation of stiffness in the lower jaw.
- Hyperpnea and dyspnea. Respirations become very rapid and then slow and irregular. Inspiration is characteristically short while expiration is greatly prolonged.
- The odor of bitter almonds may be noted on the breath or vomitus.
-A bright pink coloration of the skin due to high concentrations of oxyhemoglobin in the venous return may be confused with that of carbon monoxide poisoning.
-Unconsciousness, followed promptly by violent convulsions, epileptiform or tonic, sometimes localized but usually generalized. Opisthotonos and trismus may develop. Involuntary micturition and defecation occur. Paralysis follows the convulsive stage.
- The skin is covered with sweat. The eyeballs protrude, and the pupils are dilated and unreactive. The mouth is covered with foam, which is sometimes bloodstained. The skin color may be brick red. Cyanosis is not prominent in spite of weak and irregular gasping. In the unconscious patient, bradycardia and the absence of cyanosis may be key diagnostic signs.
-The CNS is the most sensitive target organ of cyanide poisoning, with early stimulation followed by CNS depression. Early symptoms include lightheadedness, giddiness, tachypnea, nausea, vomiting, feeling of neck constriction and suffocation, confusion, restlessness, and anxiety. Initial tachypnea results from direct stimulation of carotid body chemoreceptors followed by respiratory depression. Severe cyanide poisonings progress to stupor, coma, opisthotonus, convulsions, fixed dilated pupils, and death.
-Loss of consciousness and prompt death from respiratory arrest.

First Aid for Sodium cyanide Poisoning

For Inhalation
- Move victim to fresh air. Call 911 or emergency medical service. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
For Skin
- Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves.
For Eyes
- In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
For Ingestion
- ffects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves.
Get medical aid.

1. PAN Bad Actors are chemicals that are one or more of the following: highly acutely toxic, cholinesterase inhibitor, known/probable carcinogen, known groundwater pollutant or known reproductive or developmental toxicant. NOTE! Because there are no authoritative lists of Endocrine Disrupting (ED) chemicals, EDs are not yet considered PAN Bad Actor chemicals.

Summary of Acute Toxicity for Organism Group

Sorry, no honeybee acute toxicity data available for this chemical. Try related chemicals.

Note: Population-level effects on honeybees may occur even if a pesticide has low acute toxicity. For example, certain pesticides interfere with honeybee reproduction, ability to navigate, or temperature regulation, any of which can have an effect on long-term survival of honeybee colonies. The neonicotinoids, pyrethroids and keto-enol pesticides are some types of pesticides causing one or more of these effects.
