Product #CL2* Page 2 of 8
Section 03 - Hazard Identification
Inhalation...................鈥︹?︹?︹??.鈥?.... Chlorine is irritating to the nose, throat, and respiratory tract. Symptoms
include : coughing, shortness of breath, chest pain, nausea, vomiting, and
dizziness. Pulmonary edema (swelling) and chemical pneumonia can
develop hours after exposure. High concentrations may cause
unconsciousness and death.
Skin Contact / Absorption鈥︹??.鈥?.... High concentrations can cause severe irritation and tissue destruction.
Symptoms include: burning and prickling sensations, reddening, and
blisters. Direct contact with liquid causes severe local irritation, blistering
and burns.
Eye Contact................鈥︹?︹?︹??.鈥?.... A severe irritant of the eyes. Symptoms include: stinging and burning
sensation with excessive tear production. Direct contact with liquid may
cause burns, permanent damage, and possibly blindness.
Ingestion.....................鈥︹?︹?︹?︹?︹??. Not a likely route of exposure. Liquid may cause pain, burning, thirst,
abdominal cramps, nausea, and vomiting. Irritation and swelling of the
throat causes difficulty breathing.
Exposure Limits鈥︹?︹?︹?︹?︹?︹?︹??... ACGIH/TLV-TWA= 0.5ppm
ACGIH/TLV-STEL= 1.0ppm
Section 04 - First Aid Measures
Inhalation....................鈥︹?︹?︹?︹?︹??.. 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鈥︹?︹?︹??.. Avoid direct contact with this chemical. Remove contaminated clothing.
Wash affected area with soap and water. Seek medical attention
immediately if irritation occurs or persists.
Eye Contact..................鈥︹?︹?︹?︹??.... 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......................鈥︹?︹?︹?︹?︹??. Do not induce vomiting. If vomiting occurs, lean victim forward to prevent
breathing in vomit. Give a cup of water to dilute if patient is conscious. Do
not give anything by mouth to an unconscious or convulsing person. Seek
immediate medical attention.

Section 05 - Fire Fighting
Conditions of Flammability鈥︹?︹??.... Does not burn. Note that chlorine is a strong oxidizing agent and is a
serious fire risk.
Means of Extinction........鈥︹?︹?︹??..... Product does not burn. Where fire is involved use any fire fighting agent
that is appropriate extinguishing media for material that is supplying the
fuel to the fire. Avoid direct contact with water to leaking container
surfaces. Do not use dry chemicals, carbon dioxide or halogenated
extinguishing agents
Flash Point....鈥︹?︹?︹?︹?︹?︹?︹?︹?︹??.. Not applicable
Auto-ignition Temperature鈥︹?︹?︹??. Not applicable
Upper Flammable Limit 鈥︹?︹?︹?︹??.. Not applicable
Lower Flammable Limit...鈥︹?︹??.鈥?... Not applicable
Hazardous Combustible Products... Toxic products are formed when combustibles burn in chlorine. Water
sprayed directly on chlorine forms corrosive hypochlorous and
hydrochloric acids.
Special Fire Fighting Procedures..... Wear NIOSH-approved self-contained breathing apparatus and
protective clothing. Remove chlorine containers from fire area if safe to
do so. Use water spray to cool containers, knock down fumes, and to
direct escaping gas away from persons. Use water with caution since
chlorine in water is very corrosive. Ventilate area. Chlorine gas is heavier
than air and may collect in low areas.
Explosion Hazards鈥︹?︹?︹?︹?︹?︹??.... May react to cause fire and explosion upon contact with many organic
compounds, ammonia, hydrogen, and many metals at elevated
temperatures.
Section 06 - Accidental Release Measures
Leak / Spill................鈥?.鈥︹?︹?︹?︹??... Wear appropriate personal protective equipment. Ventilate area. Don't
spray leak with water since a reaction producing corrosive hypochlorous
and hydrochloric acids occurs, which can aggravate the leak. Stop or
reduce leak if safe to do so. Prevent material from entering sewers.
Deactivating Materials...鈥︹?︹??.鈥?... May be absorbed or neutralized into alkaline solutions of caustic soda,
lime or soda ash.

Section 07 - Handling and Storage
Handling Procedures.......鈥︹?︹?︹??... Store containers as per Chlorine Institute Guidelines. 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......鈥︹??...鈥?.. Store in a cool, dry location outdoors or in well-ventilated areas of
noncombustible materials. Refer to Chlorine Institute guidelines and local
regulations. Keep containers tightly closed, and away from incompatible
materials. Store away from sunlight and sources of heat. 68 kg cylinders
should be stored in an upright position.
Section 08 - Personal Protection and Exposure Controls
Protective Equipment

they may contribute to severe eye injury.
Respiratory鈥︹?︹?︹?︹?︹?︹?︹?︹?︹??.... Less than 5ppm-cartridge respirator with cartridge protecting against

Gloves鈥︹?︹?︹?︹?︹?︹?︹?︹?︹?︹?︹??..... Impervious gloves of chemically resistant material (rubber or PVC) should
be worn at all times. Wash contaminated clothing and dry thoroughly
before reuse.
Clothing鈥︹?︹?︹?︹?︹?︹?︹?︹??..鈥︹??.... Body suits, aprons, and/or coveralls of chemical resistant material should
