Guidance on Safe Use

First-aid measures

4.1 Description of first aid measures
General advice:
In case of discomfort / After absorbing larger amounts of sub-stance: Immediately contact a doctor or Poisons Information Centre, and follow the advice given. Show this safety data sheet to the doctor in attendance.
If inhaled:
Move to fresh air.
In case of skin contact:
Remove contaminated or saturated clothing immediately and dispose of safely.
Wash off immediately with plenty of water.
In case of eye contact
:Rinse immediately with plenty of water, also under the eyelids, for at least 10 minutes.
Remove contact lenses if this can be easily done.
Immediate further treatment in ophthalmic hospital/ ophthal-mologist.
If swallowed:
Rinse mouth.
Drink 1 or 2 glasses of water.
Do NOT induce vomiting.
If conscious and medical aid is not available immediately, induce vomiting. Be sure to keep victim´s head below hips to avoid aspiration of vomitus into the lungs.
4.2 Most important symptoms and effects, both acute and delayed
Symptoms:
Erythema
Fall in blood pressure
increased pulse frequency,
Nausea
feeling of burning,
headache
Irritation of mucous membranes

after the intake of large amounts circulatory depression up to unconsciousness are possible
Risks:
Caution: Alcoholic beverages interact with cyanamide.
Symptoms showing flush are possible (difficulty in breathing, bright red face).
4.3 Indication of any immediate medical attention and special treatment needed
Treatment:
No specific antidote known. Symptomatic treatment. After the intake of small amounts: administer activated char-coal, sodium sulfate and much liquid orally. After the intake of large amounts: monitoring of circulatory functions, if necessary irrigation of the stomach preventing aspiration and taking into account the irritating properties to mucous membranes. In case of skin irritation, use corticoid containing external preparations.
