Section 03 - Hazard Identification

Inhalation...................………….….... Dust or mist inhalation may irritate nose, throat, and lungs. Product
hydrolyzes in lungs to form sulphuric acid.

Skin Contact / Absorption…….…... May cause skin irritation, especially under repeated or prolonged contact,
or when moisture is present. May cause pain and severe burns to skin and
brownish or yellow stains. May cause redness, drying, and cracking of
skin.

Eye Contact................………….….... May irritate or burn eyes. Possible corneal damage.

Ingestion.....................………………. May irritate the gastrointestinal tract and cause nausea, vomiting, and
purging. Acute exposure can cause loss of coordination, muscle spasms,
and kidney effects.

Exposure Limits……………………... OEL/TWA: 2mg/m3

Section 04 - First Aid Measures

Inhalation....................……………….. Remove victim to fresh air. Give artificial respiration only if breathing has
stopped. If breathing is difficult, give oxygen. Seek immediate medical
attention.

Skin Contact / Absorption………….. Remove contaminated clothing. Wash affected area with soap and
water. Seek medical attention if irritation occurs or persists.

Eye Contact..................…………….... Flush immediately with water for at least 20 minutes. Forcibly hold
eyelids apart to ensure complete irrigation of eye tissue. Seek immediate
medical attention.

Ingestion......................………………. Do not induce vomiting. If vomiting occurs, lean victim forward to prevent
breathing in vomitus. Rince mouth thoroughly with water. Give 1-2
glasses of water to the victim to drink. If vomiting occurs naturally, rince
the mouth out again and give another 1-2 glasses of water. Do not give
anything by mouth to an unconscious or convulsing person. Seek
immediate medical attention.

Additional Information.....…………... Advice to physician: treat symptomatically.

Section 05 - Fire Fighting Measures

Conditions of Flammability……….... Non-flammable

Means of Extinction........…………..... Product does not burn. Where fire is involved, use any fire fighting agent
appropriate for surrounding material; use water spray to cool fire-exposed
surfaces.

Flash Point....………………………….. Not applicable

Auto-ignition Temperature…………. Not applicable

Upper Flammable Limit …………….. Not applicable

Lower Flammable Limit...……….…... Not applicable

Hazardous Combustible Products... At above 760°C or heated in open flame, sulphur oxide (toxic, corrosive,
oxidizer), sulphur trioxide (toxic,corrosive, flammable) and aluminum
oxide are released. The remaining residue is caustic.

Special Fire Fighting Procedures..... Wear NIOSH-approved self-contained breathing apparatus and
protective clothing.

Explosion Hazards………………….... None

Section 06 - Accidental Release Measures

Leak / Spill................….……………... Wear appropriate personal protective equipment. Ventilate area. Stop or
reduce leak if safe to do so. Spray residue with plenty of water. Prevent
material from entering sewers. Collect liquid and/or residue and dispose
of in accordance with applicable regulations.

Deactivating Materials...……….…... Soda ash, lime or limestone. Note that adequate ventilation is required if
soda ash or limestone is used because of possible carbon dioxide gas
formation.

Section 07 - Handling and Storage

Handling Procedures.......…………... Use proper equipment for lifting and transporting all containers. Use
sensible industrial hygiene and housekeeping practices. Wash thoroughly
after handling. Avoid all situations that could lead to harmful exposure.

Storage Requirements......……...….. Store in a cool, dry, well-ventilated place. Keep container tightly closed,
and away from incompatible materials.

Section 08 - Personal Protection and Exposure Controls

Protective Equipment
Eyes.………………………….………... Chemical goggles, full-face shield, or a full-face respirator is to be worn at
all times when product is handled. Contact lenses should not be worn;
they may contribute to severe eye injury.

Respiratory………………………….... For dusty conditions wear a NIOSH/MSHA-approved dust or mist

respirator. A respiratory protection program that meets OSHA 1910.134
and ANSI Z88.2 or applicable federal/provincial requirements must be
followed whenever workplace conditions warrant respirator use. NIOSH's
"Respirator Decision Logic" may be useful in determining the suitability of
various types of respirators.

Gloves………………………………..... Impervious gloves of chemically resistant material should be worn at all

times. Wash contaminated clothing and dry thoroughly before reuse.

Clothing………………………..…….... Body suits, aprons, and/or coveralls of chemical resistant material should
be worn at all times. Wash contaminated clothing and dry thoroughly
before reuse.

Footwear……………………………..... Impervious boots of chemically resistant material should be worn.

Engineering Controls
Ventilation Requirements………...... Mechanical ventilation (dilution or local exhaust), process or personnel
enclosure and control of process conditions should be provided. Supply
sufficient replacement air to make up for air removed by exhaust systems.

Other………………………………….... Emergency shower and eyewash should be in close proximity.
