3. Hazards Identification
EMERGENCY OVERVIEW
Corrosive and irritating to the eyes, skin and mucous membranes. Inhalation may result in chemical
pneumonitis and pulmonary edema. Nonflammable. Oxidizer, may explode or accelerate combustion
if contacting reducing agents.

HEALTH EFFECTS:

Yes Yes No
Teratogen Reproductive Hazard Mutagen
Yes Yes Yes
Synergistic Effects
Other agents that irritate the respiratory system
Carcinogenicity: -- NTP: No IARC: No OSHA: No
EYE EFFECTS:
Corrosive and irritating to the eyes. Contact with the liquid or vapor causes painful burns and ulcerations.
Burns to the eyes result in lesions and possible loss of vision.
SKIN EFFECTS:
Corrosive and irritating to the skin and all living tissue. It hydrolyzes very rapidly yielding hydrochloric acid.
Skin burns and mucosal irritation are like that from exposure to volatile inorganic acids. Chlorine burns exhibit
severe pain, redness, possible swelling and early necrosis.
INGESTION EFFECTS:
Ingestion is unlikely.
INHALATION EFFECTS:
Corrosive and irritating to the upper and lower respiratory tract and all mucosal tissue. Symptoms include
lacrimation, cough, labored breathing, and excessive salivary and sputum formation. Excessive irritation of the
lungs causes acute pneumonitis and pulmonary edema, which could be fatal. Residual pulmonary malfunction
may also occur. Chemical pneumonitis and pulmonary edema may result from exposure to the lower respiratory
tract and deep lung.
Some experimental evidence indicates chlorine causes mutagenic, teratogenic, and reproductive effects in animal
studies.

4. First Aid Measures
EYES:
PERSONS WITH POTENTIAL EXPOSURE SHOULD NOT WEAR CONTACT LENSES. Flush
contaminated eye(s) with copious quantities of water. Part eyelids to assure complete flushing. Continue for a
minimum of 15 minutes. Seek immediate medical attention.
MSDS: G-23
Revised: 6/7/96 Page 2 of 7
PRODUCT NAME: CHLORINE
SKIN:
Remove contaminated clothing as rapidly as possible. Flush affected area with copious quantities of water.
Seek immediate medical attention.
INGESTION:
None required.
INHALATION:
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE. RESCUE
PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS.
Conscious persons should be assisted to an uncontaminated area and inhale fresh air. Unconscious persons
should be moved to an uncontaminated area and given artificial resuscitation and supplemental oxygen. Assure
that mucus or vomited material does not obstruct the airway by use of positional drainage. Delayed pulmonary
edema may occur. Keep the patient under medical observation for at least 24 hours.
5. Fire Fighting Measures
Conditions of Flammability: Not flammable
Flash point: Method: Autoignition
None Not Applicable Temperature: None
LEL(%): None UEL(%): None
Hazardous combustion products: None
Sensitivity to mechanical shock: None
Sensitivity to static discharge: None
FIRE AND EXPLOSION HAZARDS:
Combustible materials burn in chlorine as they do in oxygen.
EXTINGUISHING MEDIA:
None required. Use media suitable for surrounding materials.
6. Accidental Release Measures
Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user鈥檚 equipment,
be certain to purge piping with inert gas prior to attempting repairs. If leak is in container or container valve,
contact the appropriate emergency telephone number listed in Section 1 or call your closest BOC location.
7. Handling and Storage
Electrical classification:
Nonhazardous.
Most metals corrode rapidly with wet chlorine. Systems must be kept dry. Lead, gold, tantalum and Hastelloy
are most resistant to wet chlorine.
MSDS: G-23
Revised: 6/7/96 Page 3 of 7
PRODUCT NAME: CHLORINE
Use only in well-ventilated areas. Valve protection caps must remain in place unless container is secured with
valve outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder
movement. Use a pressure reducing regulator when connecting cylinder to lower pressure (<250 psig) piping or
systems. Do not heat cylinder by any means to increase rate of product from the cylinder. Use a check valve or
trap in the discharge line to prevent hazardous back flow into cylinder.
Protect cylinders from physical damage. Store in cool, dry, well-ventilated areas of non-combustible
construction away from heavily trafficked areas and emergency exits. Do not allow the temperature where
cylinders are stored to exceed 125oF (52oC). Cylinders should be stored upright and firmly secured to prevent
falling or being knocked over. Full & empty cylinders should be segregated. Use a "first in-first out" inventory
system to prevent full cylinders from being stored for excessive periods of time.
For additional storage recommendations, consult Compressed Gas Association鈥檚 Pamphlet P-1.
Never carry a compressed gas cylinder or a container of a gas in cryogenic liquid form in an enclosed space such
as a car trunk, van or station wagon. A leak can result in a fire, explosion, asphyxiation or a toxic exposure.
