Potential Health Effects:
Page 2 of 9
Inhalation: Causes respiratory irritation and at high concentrations may cause severe injury and
burns to the mucous membranes and lungs.
Skin Contact: Corrosive to skin and can cause burns. Prolonged or repeated exposure to dilute
solutions may cause irritation, redness, pain and drying and cracking of the skin.
Eye Contact: Can cause severe burns and corneal damage, which may result in permanent blindness.
Ingestion: Causes burns of the mouth, throat, esophagus and stomach.
Chronic Effects: No chronic effects expected.
Existing Medical Conditions Possibly Aggravated By Exposure : Skin irritation may be
aggravated in individuals with existing skin lesions. Breathing of vapors or mists may aggravate acute
or chronic asthma and chronic pulmonary disease such as emphysema and bronchitis.
Carcinogenicity: Aluminum sulfate is not classified as carcinogenic by ACGIH (American
Conference of Governmental Industrial Hygienists) or IARC (International Agency for Research on
Cancer), not regulated as carcinogens by OSHA (Occupational Safety and Health Administration),
and not listed as carcinogens by NTP (National Toxicology Program).
SECTION 4 - FIRST AID MEASURES
General: If you feel unwell seek medical advice (show the label where possible).
Inhalation: Move victim to fresh air. Give artificial respiration ONLY if breathing has stopped. Do
not use mouth -to -mouth method if victim ingested or inhaled the substance: induce artificial
respiration with the aid of a pocket mask equipped with a one -way valve or other proper respiratory
medical device. Give Cardiopulmonary Resuscitation (CPR) only if there is no pulse AND no
breathing. Obtain medical attention IMMEDIATELY.
Skin Contact: Immediately flush skin with running water for at least 15 - 20 minutes. Under running
water remove contaminated clothing, jewelry, and shoes. If irritation persists, repeat flushing. For
burns, obtain medical attention. Discard heavily contaminated clothing and shoes in a manner, which
limits further exposure. Otherwise, wash clothing separately before reuse.
Eye Contact: Immediately flush eyes with running water for a minimum of 15 minutes. Hold eyelids
open during flushing. If irritation persists, repeat flushing. Obtain medical attention IMMEDIATELY.
Do not transport victim until the recommended flushing period is completed unless flushing can be
continued during transport.
Ingestion: DO NOT INDUCE VOMITING. If victim is alert and not convulsing, rinse mouth and
give as much water as possible to dilute material. If spontaneous vomiting occurs, have victim lean
forward with head down to avoid breathing in of vomitus, rinse mouth and administer more water.
IMMEDIATELY transport victim to an emergency facility.

Fire and Explosion Hazards: Not flammable. Sulfuric acid may react with many metals to
liberate hydrogen gas, which can form explosive mixtures with air. Hydrogen, a highly
flammable gas, can accumulate to explosive concentrations inside drums, or any types of steel
containers or tanks upon storage. Oxides of sulfur and aluminum may be produced in fire.
Extinguishing Media : Small fires: Dry chemical, carbon dioxide or water spray. Large fires:
Dry chemical, carbon dioxide, alcohol- resistant foam or water spray.
Special Information: Firefighters should wear acid resistant protective equipment and self -
contained breathing apparatus with full facepiece operated in positive pressure mode. Move
containers from fire area if you can do it without risk. Dike fire control water for later disposal;
do not scatter the material. Fire involving tanks or car /trailer loads: Fight fire from maximum
distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers.
Cool containers with flooding quantities of water until well after fire is out. Withdraw
immediately in case of rising sound from venting safety devices or discoloration of tank.
ALWAYS stay away from the ends of tanks.
Evacuation: If tank, rail car or tank truck involved in a fire, ISOLATE and consider evacuation
of one -half (1/2) mile radius.
NOTE: Also see "Section 10 - Stability and Reactivity"
I SECTION 6 — ACCIDENTAL RELEASE MEASURES
Spills, Leaks, or Releases:
• Restrict access to area until completion of clean up. Ensure trained personnel conduct clean up.
• Remove all ignition sources (no smoking, flares, sparks or flames). All equipment should be
grounded. Ventilate area.
• Wear adequate personal protective equipment. Do not touch spilled material.
• Stop leak if possible without personal risk.
• Small shills: Cover with DRY earth, sand or other non - combustible material. Use clean non-
sparking tools to collect material and place it into loosely covered plastic containers for later
disposal.
• Lame shills: Prevent entry into sewers and confined areas. Dike with inert material (sand, earth,
etc.). Collect into plastic containers for disposal. Consider insitu neutralization and disposal.
Ensure adequate decontamination of tools and equipment following clean up. Comply with
Federal, Provincial/State and local regulations on reporting releases.

SECTION 7 — HANDLING AND STORAGE
Precautions: Have emergency equipment (for fires, spills, leaks, etc.) readily available. Ensure all
containers are labeled. Wear appropriate Personal Protection Equipment. People working with this
chemical should be properly trained regarding its hazards and its safe use.
Handling Procedures and Equipment: Keep containers closed when not in use. Empty containers
may contain hazardous residues. Use corrosion- resistant transfer equipment when dispensing.
Storage Requirements: Liquid alum may be received and stored in corrosion- resistant tanks. Store
in a cool, dry, well - ventilated area, out of direct sunlight. Store away from incompatible materials
such as strong bases. Keep containers tightly closed when not in use and when empty. Protect from
damage.
Outdoor storage tanks should be suitably diked or otherwise provided with an adequate means of
secondary containment. Appropriate secondary containment measures should be taken to prevent
spills or leaks from indoor storage tanks and tank -car or tank -truck unloading stations from entering
sewers or other channels that discharge directly to a water body or a municipal sewage system.
SECTION 8 — EXPOSURE CONTROLS / PERSONAL PROTECTION I
PREVENTIVE MEASURES
Recommendations listed in this section indicate the type of equipment, which will provide
protection against over exposure to this product. Conditions of use, adequacy of engineering
or other control measures, and actual exposures will dictate the need for specific protective
devices at your workplace.
Engineering Controls: Local exhaust ventilation should be applied wherever there is an incidence
of point source emissions or dispersion of regulated contaminants in the work area. Ventilation
control of the contaminant as close to its point of generation is both the most economical and safest
method to minimize personnel exposure to airborne contaminants. The most effective measures are
the total enclosure of processes and the mechanization of handling procedures to prevent all personal
contact. Smoking should be prohibited in areas in which aluminum sulfate solution is stored or
handled.
