In Vivo A 25 microliter volume of a 1-% L-epinephrine borate solution applied on the cornea of one eye in 12 monkeys reduces blood flow through the iris and the ciliary body by 59% and 20%, respectively, compared to the untreated control eyes[1]. Epinephrine is a direct-acting sympathomimetic α-adrenergic and β-adrenergic agonist with cyclic adenosine monophosphate-mediated, complex, bidirectional pharmacologic effects on many target organs[2]. In young adult rats, endogenous release of epinephrine facilitates stable memory formation for temporally associated events. Epinephrine enhances memory in young adult rats, in part, by increasing blood glucose levels needed to modulate memory[3]. Epinephrine is the primary drug administered during cardiopulmonary resuscitation (CPR) to reverse cardiac arrest. Epinephrine increases arterial blood pressure and coronary perfusion during CPR via alpha-1-adrenoceptor agonist effects[4].

Section 3. Hazards Identification
Potential Acute Health Effects Very hazardous in case of ingestion, of inhalation. Hazardous in case of skin contact (irritant, permeator), of eye
contact (irritant). Severe over-exposure can result in death.
Potential Chronic HealthVery hazardous in case of ingestion, of inhalation.
Hazardous in case of skin contact (irritant, permeator), of eye contact (irritant).
Effects
CARCINOGENIC EFFECTS: Not available.
MUTAGENIC EFFECTS: Not available.
TERATOGENIC EFFECTS: Not available.
DEVELOPMENTAL TOXICITY: Not available.
The substance is toxic to lungs, the nervous system, mucous membranes.
Repeated or prolonged exposure to the substance can produce target organs damage. Repeated exposure to an
highly toxic material may produce general deterioration of health by an accumulation in one or many human
organs.

Section 4. First Aid Measures
Eye ContactCheck for and remove any contact lenses. Immediately flush eyes with running water for at least 15 minutes,
keeping eyelids open. Cold water may be used. Do not use an eye ointment. Seek medical attention.
Skin ContactAfter contact with skin, wash immediately with plenty of water. Gently and thoroughly wash the contaminated skin
with running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin.
Cold water may be used. Cover the irritated skin with an emollient. If irritation persists, seek medical attention.
Wash contaminated clothing before reusing.
Serious Skin ContactWash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate
medical attention.
InhalationAllow the victim to rest in a well ventilated area. Seek immediate medical attention.
Serious InhalationEvacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth
resuscitation. Seek medical attention.
IngestionDo not induce vomiting. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible
indication that the toxic material was ingested; the absence of such signs, however, is not conclusive. Loosen
tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth
resuscitation. Seek immediate medical attention.

Section 7. Handling and Storage
PrecautionsKeep locked up Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire risk,
evaporate the residue under a fume hood. Ground all equipment containing material. Do not ingest. Do not
breathe dust. Wear suitable protective clothing In case of insufficient ventilation, wear suitable respiratory
equipment If ingested, seek medical advice immediately and show the container or the label. Avoid contact with
skin and eyes
StorageKeep container dry. Keep in a cool place. Ground all equipment containing material. Keep container tightly
closed. Keep in a cool, well-ventilated place. Highly toxic or infectious materials should be stored in a separate
locked safety storage cabinet or room.

Section 8. Exposure Controls/Personal Protection
Engineering ControlsUse process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
airborne contaminants below the exposure limit.
Personal ProtectionSplash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.
Gloves.
Personal Protection in Case of Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used
a Large Spillto avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist
BEFORE handling this product.
