3. HAZARDS IDENTIFICATION
Potential Health Effects
Eye
Can cause permanent eye injury. Symptoms include stinging,
tearing, redness, and swelling of eyes. Can injure the cornea and
cause blindness.
Skin
Both the liquid and vapor can cause severe burns which may not be
immediately painful or visible.
Swallowing
Swallowing this material may be harmful or fatal. Symptoms may
include severe stomach and intestinal irritation (nausea,
vomiting, diarrhea), abdominal pain, and vomiting of blood.
Swallowing this material may cause burns and destroy tissue in the
mouth, throat, and digestive tract. Low blood pressure and shock
may occur as a result of severe tissue injury.
Inhalation
Breathing of vapor or mist is possible. Breathing this material
may be harmful or fatal. Symptoms may include severe irritation
and burns to the nose, throat, and respiratory tract.
Symptoms of Exposure

4. FIRST AID MEASURES
Eyes
If material gets into the eyes, immediately flush eyes gently with
water for at least 15 minutes while holding eyelids apart. If
symptoms develop as a result of vapor exposure, immediately move
individual away from exposure and into fresh air before flushing
as recommended above. Seek immediate medical attention.
Skin
Immediately flush contaminated skin with large quantities of cool
water for at least 15 minutes. Remove contaminated clothing. As
soon as possible apply 2.5% calcium gluconate gel to all affected
skin areas. The gel should be massaged into the affected skin by
personnel wearing protective gloves to prevent skin contamination
during first aid. Alternatively, affected areas may be soaked in
either iced 0.2% water solution of Hyamine 1622 or iced 0.13%
water solution of Zephiran chloride. If Hyamine 1622 or Zephiran
chloride solutions are not available, use an iced saturated water
solution of magnesium sulfate (Epsom salts), or if that is not
available, iced 70% alcohol or ice water. Get medical attention
as soon as possible. :::NOTE:::Calcium gluconate gel can be
prepared by mixing a 10 milliliter ampule of calcium gluconate
with a 2-ounce tube of K-Y jelly (Johnson & Johnson). After a jar
of this mixture has been opened and used it should be discarded to
prevent bacterial or chemical contamination. If Hyamine or
Zephiran solutions are used, they should be prepared in advance
and kept in a refrigerator in the first aid area.
Swallowing
Seek immediate medical attention. Do not induce vomiting.
Vomiting will cause further damage to the mouth and throat. If
individual is conscious and alert, immediately rinse mouth with
water and give milk or water to drink. If possible, do not leave
individual unattended. Several glasses of milk may also be given.
The calcium in milk and the magnesium in milk of magnesia will act
as an antidote in cases of hydrofluoric acid ingestion.
Inhalation
If symptoms develop, move individual away from exposure and into
fresh air. If symptoms persist, seek medical attention. If
breathing is difficult, administer oxygen. Keep person warm and
quiet; seek immediate medical attention.
Note to Physicians
Preexisting disorders of the following organs (or organ systems)
may be aggravated by exposure to this material: skin, lung (for
example, asthma-like conditions), Exposure to this material may
aggravate any preexisting condition sensitive to a decrease in
available oxygen, such as chronic lung disease, coronary artery
disease or anemias.

water fog.
Fire Fighting Instructions
Water may be used to keep fire-exposed containers cool until fire
is out. Wear a self-contained breathing apparatus with a full
facepiece operated in the positive pressure demand mode with
appropriate turn-out gear and chemical resistant personal
protective equipment. Refer to the personal protective equipment
section of this MSDS.

6. ACCIDENTAL RELEASE MEASURES
Small Spill
Cover the contaminated surface with sodium bicarbonate or a soda
ash/flaked lime mixture (50-50). Mix and add water if necessary to
form a slurry. Scoop up slurry and wash site with soda ash
solution. Proper mixing procedures are essential. Trained
personnel should conduct this procedure. Untrained personnel
should be removed from the spill area.
Large Spill
Persons not wearing protective equipment should be excluded from
area of spill until clean-up is completed. Stop spill at source.
Dike to prevent spreading. Pump to salvage tank.

7. HANDLING AND STORAGE
Handling
Containers of this material may be hazardous when emptied. Since
emptied containers retain product residues (vapor, liquid, and/or
solid), all hazard precautions given in the data sheet must be
observed. Addition to water releases heat which can result in
violent boiling and spattering. Always add slowly and in small
amounts. Never use hot water. Never add water to acids. Always
add acids to water.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Eye Protection
Chemical splash goggles and face shield (8" min.) in compliance
with OSHA regulations are advised; however, OSHA regulations also
permit other type safety glasses. (Consult your industrial
hygienist.)
Skin Protection
Wear resistant gloves such as: neoprene, polyvinyl chloride, To
prevent skin contact, wear impervious clothing and boots..
Respiratory Protections
If workplace exposure limit(s) of product or any component is
exceeded (see exposure guidelines), a NIOSH/MSHA approved air
supplied respirator is advised in absence of proper environmental
control. OSHA regulations also permit other NIOSH/MSHA
respirators (negative pressure type) under specified conditions
(see your industrial hygienist). Engineering or administrative
controls should be implemented to reduce exposure.
Engineering Controls
Provide sufficient mechanical (general and/or local exhaust)
ventilation to maintain exposure below TLV(s).
