Potential Health Effects / Health Hazard Identification
Acute Exposure:Eye:
May cause irritation, experienced as mild discomfort and seen as slight excess
redness of the eye.
Skin:
Brief contact may cause slight irritation. Prolonged contact, as with clothing wettedwith material, may cause more severe irritation and discomfort, seen as local
redness and swelling. Other than the potential skin irritation effects noted above,
acute (short term) adverse effects are not expected from brief skin contact; seeother effects below and Section 11 for information regarding potential long term
effects.
Ingestion:
Contains ethylene glycol, which is toxic when swallowed. A lethal dose for an adultis 1-2 ml per kilogram, or about 4 ounces (one-half cup or 120 ml.). Symptoms
include headache, weakness, con-fusion, dizziness, staggering, slurred speech,
loss of coordination, faintness, nausea and vomiting, increased heart rate,
decreased blood pressure, difficulty breathing and seeing, pulmonary edema,
unconsciousness, convulsions, collapse, and coma. Symptoms may be delayed.
Decreased urine output and kidney failure may also occur. Severe poisoning may
cause death. Aspiration may occur during swallowing or vomiting, resulting in lungdamage.
Inhalation:Vapors or mist in excess of permissible concentrations, or in unusually highconcentrations generated from spraying, heating the material or as from exposurein poorly ventilated areas or confined spaces, may cause irritation of the nose andthroat, headaches, nausea and drowsiness. Prolonged or repeated overexposure
may result in the absorbance of potentially harmful amounts of material.

Chronic Exposure:

Chronic inhalation of stannic oxide causes a benign form of pneumoconiosis known
as stannosis. Repeated ingestion of ethylene glycol may cause kidney damage.

Immediately flush eyes with plenty of water for at least 15 minutes. Hold eyelids
apart while flushing to rinse entire surface of the eye and lids with water. Get
medical attention.
Wash skin with plenty of soap and water for several minutes. Get medical attention
if skin irritation develops or persists.
If a person is conscious and can swallow, immediately give two glasses of water (16oz. or 500 ml.) but do not induce vomiting. If vomiting occurs, give fluids again.
Have physician determine if condition of person will permit induction of vomiting orevacuation of stomach. Do not give anything by mouth to an unconscious orconvulsing person.
If inhaled, remove to fresh air. If not breathing, clear person’s airway and give
artificial respiration. If breathing is difficult, qualified medical personnel may
administer oxygen. Get medical attention immediately.
Eye wash station.
Ethylene glycol poisoning may initially produce behavior changes, drowsiness,vomiting, diarrhea, thirst, and convulsions. End-stage signs of poisoning are renal
damage/failure with metabolic acidosis. Immediate treatment, supplemented withhemodialysis if indicated, may limit the progression and severity of toxic effects.
Intravenous ethanol in sodium bicarbonate solution is a recognized antidotaltreatment; other antidotal treatments also exist for ethylene glycol poisoning.
Contact a Poison Center for further treatment information.
Aspiration of this product during induced emesis may result in severe lung injury.
If evacuation of stomach is necessary, use method least likely to cause aspiration,such as gastric lavage after endotracheal intubation. Contact a Poison Center for
additional treatment information.
Tin oxide (stannic oxide) has a very low order of toxicity. Colloidal tin oxide has
been used as a hepatolienographic agent by intravenous injection in rabbits anddogs without reaction or obvious harm, see The American Journal of Roentgenology, Radium Therapy and Nuclear Medicine, Vol. LXXVII, No. 1, January, 1957, “ANew Hepatolienographic Agent: Tin Oxide”, Harry W. Fischer, M.D. For a general
overview see Toxicological Profile for Tin, U.S. Department of Health and HumanServices; PB93-110864.

Special Exposure Hazard:

Combustible, material will burn in a fire. Containers can build pressure if exposedto heat or fire.
Use water spray, dry chemical, foam, or carbon dioxide to extinguish flames. Usewater spray to cool fire-exposed containers. Water or foam may cause frothing.
Wear standard full firefighter turn-out gear (full bunker gear) and respiratory
protection (SCBA).

Personal Protection:

Storage:

If more than 1 pound of product is spilled, then report spill according to SARA 304
and CERCLA 102(A) requirements.
Emergency responders should wear eye protection and impervious gloves. Anapproved air-purifying respirator should be worn if dust or mist is present. See
Section 8.

Avoid generating mist or dust during use. Minimum feasible handling andtemperatures should be maintained.
Store in cool dry area. Do not freeze. Periods of exposure to high temperatures
should be minimized. Water contamination should be avoided.

Ventilate area. Avoid breathing vapor. Wear appropriate personal protective
equipment, including appropriate respiratory protection. Contain spill if possible.
Wipe up or absorb on suitable material and shovel up. Prevent entry into sewers
and waterways. Avoid contact with skin, eyes or clothing.

Ventilation adequate to meet occupational exposure limits. The OSHA ceiling is 50
ppm; ACGIH ceiling is 50 ppm.
Airborne concentrations should be kept to lowest levels possible. If vapor, mist or
dust is generated and the occupational exposure limit of the product, or any
component of the product, is exceeded, use appropriate NIOSH or MSHA approved
air purifying or air supplied respirator after determining the airborne concentrationof the contaminant. Air-supplied respirators should always be worn when airborne
concentrations of the contaminant or oxygen content is unknown.
Wear clean body-covering clothing and impervious gloves such as neoprene.
Workers should wash exposed skin several times daily with soap and water. Soiled
work clothing should be laundered or dry-cleaned.
Safety glasses, chemical type goggles, or face shield recommended to prevent eyecontact.
