First-aid measures

4.1 Description of first aid measures
General advice: Move out of dangerous area.
Immediate medical attention is required.
Show this safety data sheet to the doctor in attendance.
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.
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 re-covery position and get medical attention immediately.


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.

If inhaled: Remove victim to fresh air and keep at rest in a position com-fortable for breathing.
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 skin contact: If skin irritation persists, call a physician.
Wash contaminated clothing before reuse.
If on skin, rinse well with water.
If on clothes, remove clothes.
In case of eye contact
: Small amounts splashed into eyes can cause irreversible tis-sue 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.

If swallowed
: 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.

4.2 Most important symptoms and effects, both acute and delayed
Symptoms :
Skin contact may provoke the following symptoms:
Allergic reactions
Redness
Inhalation may provoke the following symptoms:
Shortness of breath
Asthma
Ingestion may provoke the following symptoms:
Eye contact
Excessive lachrymation

4.3 Indication of any immediate medical attention and special treatment needed
Treatment:
Ensure vital functions only without any personal risk.Rapid treatment with antidotes can save lives and has priority over removal of poison !
Antidote treatment:
Warning! Dosage level relevant for adults weighing 70 kg.
In case of slight poisoning or danger of reabsorption (intake method: skin, gastro-intestinal tract): Possible administration of sodium thiosulphate (12,5 g i.v.) depending on the clinical symptoms.
In the event of severe poisoning, administration of an antidote necessary.
Antidote treatment: Check if these antidotes are licensed in your country or check for alternatives
Dicobalt edetate/sodium thiosulphate: 300 mg (1 vial) dicobalt edetate i.v., combination with sodium thiosulphate possible. Antidote in the event of false diagnosis or overdosage: sodi-um calcium edetate.Hydroxocobalamin/sodium thiosulphate: 4 g hydroxocobalamin by slow infusion; then 8 g sodium thiosulphate by infusion. The hydroxocobalamin dosage can be raised if necessary.
Amyl nitrite/sodium nitrite/sodium thiosulphate: amyl nitrite every 15 to 30 seconds by inhalation, then 300 - 600 mg sodi-um nitrite i.v., then 12,5 g sodium thiosulphate by infusion. Antidote in the event of false diagnosis or overdosage (me-themoglobinemia > 30 %): toluidine blue, methylene blue.
4-dimethylaminophenol, 4-DMAP/sodium thiosulphate: 250 mg (1 vial) 4-DMAP i.v., then 12,5 g sodium thiosulphate by infusion. Antidote in the event of false diagnosis or overdos-age (methemoglobinemia > 30 %): toluidine blue, methylene blue.
Symptomatic treatment
administration of oxygen, artificial respiration, treatment of arrhythmias, treatment of spasmodic fit, correction of acid-base balance. Follow-up of patient, if reabsorption possible (after oral intake, after skin absorption).

In case of contact consider corrosive action not only toxicity.

If substance has been swallowed:
If swallowed, rinse mouth with water (only if the person is conscious). First administrate antidote, if necessary. Early endoscopy in order to assess mucosa lesions in the oesoph-agus and stomach which may appear.
The administration of activated charcoal is disputed.
