Guidance on Safe Use
Administrative data
First-aid measures
General advice:
Move out of dangerous area. Immediate medical attention is required. Show the safety data sheet to the doctor in attendance. Remove victim to fresh air and keep at rest in a position comfortable for breathing. Loosen tight clothing such as a collar, tie, belt or waistband. If not breathing, if breathing is irregular or if respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel. Do not leave the victim unattended. The following recommendations in respect of first aid and therapy should be made available to all First Aid Officers and Doctors, who could be called upon to render first aid, before work with cyanide/hydrocyanic acid is started. Adverse health effects could include the following: Headache, dizziness/vertigo, nausea or vomiting, convulsive seizures, unconsciousness, shortness of breath/breathing difficulty, cardiac arrest or heart failure. Take off immediately all contaminated clothing. If breathing is difficult, give oxygen. If not breathing, give artificial respiration.
After inhalation:
No mouth-to-mouth or mouth-to-nose artificial respiration. Use artificial respiration bag or respirator. Keep person warm and at rest. If unconscious, place in recovery position and get medical attention immediately. Call emergency doctor immediately (alarm report: cyanide / hydro-cyanic acid poisoning). If unconscious, place in recovery position and get medical attention immediately. In case of inhalation of decomposition products in a fire, symptoms may be delayed.
Protection of first-aiders:
No action shall be taken involving any personal risk or without suitable training. If it is suspected that fumes are still present, the rescuer should wear an appropriate mask or self-contained breathing apparatus. It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation. Wash contaminated clothing thoroughly with water before removing it, or wear gloves.
In case of skin contact:
Take victim immediately to hospital. Wash contaminated clothing before reuse. Immediately remove the substance from the skin. If on skin, rinse well with water. Flush contaminated skin with plenty of water.
In case of eye contact:
Small amounts splashed into eyes can cause irreversible tissue damage and blindness. Remove contact lenses. In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Continue rinsing eyes during transport to hospital. Protect unharmed eye. Keep eye wide open while rinsing. If eye irritation persists, consult a specialist.
After swallowing:
Clean mouth with water and drink afterwards plenty of water. Call emergency doctor immediately (alarm report: cyanide / hydro-cyanic acid poisoning). Keep respiratory tract clear. Do NOT induce vomiting. Rinse mouth with water. Never give anything by mouth to an unconscious person. Take victim immediately to hospital.
