Potential Health Effects
----------------------------------
Although this material is not as dangerous as certain cyanide compounds like hydrogen
cyanide and sodium cyanide, it can cause cyanide poisoning. People who work with or
around this material should be trained in first aid measures for cyanide overexposures.
Symptoms of cyanide poisoning include salivation, nausea without vomiting, anxiety,
confusion, giddiness, vertigo, lower jaw stiffness, convulsions, paralysis, spasm of the
back muscles causing the head and lower limbs to bend backward and the trunk to arch
forward, coma, irregular heartbeat, respiratory stimulation followed by respiratory
failure, and death. In most cases, cyanide poisoning causes a deceptively healthy pink to
red skin color. However, if a physical injury or lack of oxygen is involved, the skin color
may be bluish. Reddening of the eyes and pupil dilation are symptoms of cyanide
poisoning. Cyanosis (blue discoloration of the skin) tends to be associated with severe
cyanide poisonings.
Inhalation:
Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of
breath. Other symptoms may include weakness, headaches, confusion, flushing,
occasional nausea and vomiting, increased respiratory rate and pulse followed by
decreased respiratory rate and pulse.
Ingestion:
Causes irritation to the gastrointestinal tract. Symptoms may include nausea, vomiting
and diarrhea. Other symptoms may parallel those from inhalation.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain. May be absorbed
through the skin with possible systemic effects.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
No information found.
4. First Aid Measures
The following first aid procedures apply when cyanide poisoning is suspected. If cyanide
poisoning is not suspected, lesser first aid measures will be appropriate.
FOR ANY ROUTE OF EXPOSURE ADMINISTER AMYL NITRITE, SODIUM
NITRITE AND SODIUM THIOSULFATE PER PRE-PLANNED INSTRUCTIONS. IN
CASE OF CYANIDE POISONING, start first aid treatment immediately, then get
medical attention. A cyanide antidote kit (amyl nitrite, sodium nitrite and sodium
thiosulfate) should be available in any cyanide work area. Actions to be taken in case of
cyanide poisoning should be planned and practiced before beginning work with cyanides.
Oxygen and amyl nitrite can be given by a first responder before medical help arrives.
Allow victim to inhale amyl nitrite for 15-30 seconds per minute until sodium nitrite and
sodium thiosulfate can be administered intravenously (see Note to Physician). A new
amyl nitrite ampule should be used every 3 minutes. If conscious but symptoms (nausea,
difficult breathing, dizziness, etc.) are evident, give oxygen. If consciousness is impaired
(non-responsiveness, slurred speech, confusion, drowsiness) or the patient is unconscious
but breathing, give oxygen and amyl nitrite by means of a respirator. If not breathing,
give oxygen and amyl nitrite immediately by means of a positive pressure respirator
(artificial respiration).
Inhalation:
IF INHALED, remove to fresh air. If not breathing, give artificial respiration. DO NOT
GIVE MOUTH-TO-MOUTH RESUSCITATION. If breathing is difficult, give oxygen.
Keep patient warm and at rest.
Ingestion:
If ingested and the patient is conscious, immediately give the patient activated charcoal
slurry. Never give anything by mouth to an unconscious person. Do not induce vomiting
as it could interfere with resuscitator use.
Skin Contact:
In case of contact, immediately flush eyes or skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and
upper eyelids occasionally. Get medical attention immediately.
Note to Physician:
If patient does not respond to amyl nitrite, inject intravenously with 10mL of a 3%
solution of sodium nitrite at a rate of not more than 2.5 to 5 mL per minute.Once nitrite
administration is complete, follow directly with 50 mL of a 25% solution of sodium
thiosulfate at the same rate by the same route. Give victim oxygen and keep under
observation. If exposure was severe, watch victim for 24-48 hours. If signs of cyanide
poisoning persist or reappear, repeat nitrite and thiosulfate injections 1 hour later in 1/2
the original doses. Cyanocabalamin (B12), 1 mg intramuscularly, may speed recovery.
Moderate cyanide exposures need be treated only by supportive measures such as bed
rest and oxygen.
5. Fire Fighting Measures
Fire:
Flash point: 72C (162F) CC
Combustible Liquid and Vapor!
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits noted above.
Fire Extinguishing Media:
Dry chemical, foam or carbon dioxide. Water may be ineffective. Water spray may be
used to keep fire exposed containers cool.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained
breathing apparatus with full facepiece operated in the pressure demand or other positive
pressure mode. May emit toxic and flammable fumes of cyanide if involved in a fire.
6. Accidental Release Measures
Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal
protective equipment as specified in Section 8. Isolate hazard area. Keep unnecessary and
unprotected personnel from entering. Contain and recover liquid when possible. Use non-
sparking tools and equipment. Collect liquid in an appropriate container or absorb with an
inert material (e. g., vermiculite, dry sand, earth), and place in a chemical waste
container. Do not use combustible materials, such as saw dust. Do not flush to sewer! US
Regulations (CERCLA) require reporting spills and releases to soil, water and air in
excess of reportable quantities. The toll free number for the US Coast Guard National
Response Center is (800) 424-8802.
J. T. Baker SOLUSORB?solvent adsorbent is recommended for spills of this product.
7. Handling and Storage
Keep in a tightly closed container. Store in a cool, dry, ventilated area away from sources
of heat or ignition. Protect against physical damage. Store separately from reactive or
combustible materials, and out of direct sunlight. All persons with the potential for
cyanide poisoning should be trained to provide immediate First Aid using oxygen and
amyl nitrite. A cyanide anitdote kit (amyl nitrite, sodium nitrite, and sodium thiosulfate)
should be readily available in cyanide workplaces. The antidotes should be checked
annually to ensure they are still within their shelf-lives. Identification of community
hospital resources and emergency medical squads in order to equip and train them on
handling cyanide emergencies is essential. Containers of this material may be hazardous
when empty since they retain product residues (vapors, liquid); observe all warnings and
precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL):
for hydrogen cyanide = 10 ppm (TWA), skin.
-ACGIH Threshold Limit Value (TLV):
for hydrogen cyanide = 4.7 ppm, ceiling, skin.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures
below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred
because it can control the emissions of the contaminant at its source, preventing
dispersion of it into the general work area. Please refer to the ACGIH document,
Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for
details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded and engineering controls are not feasible, wear a
supplied air, full-facepiece respirator, airlined hood, or full-facepiece self-contained
breathing apparatus. Breathing air quality must meet the requirements of the OSHA
respiratory protection standard (29CFR1910.134).
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or
coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible.
Maintain eye wash fountain and quick-drench facilities in work area.
