**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed.
Irritating to eyes, respiratory system and skin.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. Harmful if absorbed through the skin. May
be metabolized to cyanide which in turn acts by inhibiting cytochrome
oxidase impairing cellular respiration. Most nitrile compounds are
well absorbed through intact skin, and may cause delayed onset of
symptoms following exposure by this route.
Ingestion:
May cause irritation of the digestive tract. Poison by ingestion.
May cause cardiac disturbances. May cause central nervous system
depression. Metabolism may release cyanide, which may result in
headache, dizziness, weakness, collapse, unconsciousness and possible
death.
Inhalation:
Harmful if inhaled. May cause respiratory tract irritation. May
cause cardiac abnormalities. Inhalation may result in symptoms
similar to cyanide poisoning which include tachypnea, hyperpnea
(abnormally rapid or deep breathing), and dyspnea (labored breathing)
followed rapidly by respiratory depression. Pulmonary edema may
occur. Inhalation at high concentrations may cause CNS depression and
asphixiation.
Chronic:
May be metabolized to cyanide which in turn acts by inhibiting
cytochrome oxidase impairing cellular respiration. Chronic exposure
to cyanide solutions may lead to the development of a "cyanide" rash,
characterized by itching, and by macular, papular, and vesicular
eruptions, and may be accompanied by secondary infections. Exposure
to small amounts of cyanide compounds over long periods of time is
reported to cause loss of appetite, headache, weakness, nausea,
dizziness, and symptoms of irritation of the upper respiratory tract
and eyes.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
May be partially metabolized to cyanide in the body.
Antidote:
Always have a cyanide antidote kit on hand when working with cyanide
compounds. Get medical advice to use.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Runoff from
fire control or dilution water may cause pollution. Approach fire
from upwind to avoid hazardous vapors and toxic decomposition
products.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, or water spray.
For large fires, use dry chemical, carbon dioxide, alcohol-resistant
foam, or water spray. Cool containers with flooding quantities of
water until well after fire is out.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. Do not
get in eyes, on skin, or on clothing. Keep container tightly closed.
Avoid ingestion and inhalation. Use only in a chemical fume hood.
Avoid breathing dust.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 2856-63-5:
United States OSHA: 5 mg/m3 TWA (listed under Cyanide anion).
Germany: (listed as cyanide anion): Skin absorber

Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
