===================== Hazards Identification =====================
Routes of Entry: Inhalation:Yes Skin:Yes Ingestion:Yes
Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:Ingestion: Chlorine is a gas at room
temperature. Ingestion of liquid chlorine may result in severe
irritation or ulceration of the mouth, throat and digestive tract
which may be displayed by nausea, pain, vomiting, cyanosis (lack of
oxygen in the blood), and, in severe cases, collapse, shock and
death., Inhalation: Major potential route of exposure. Exposure to
chlorine gas may cause severe irritation of mucous membranes of the
nose, throat, and respiratory tract followed by severe coughing,
burning, chest pain, vomiting, headache, anxiety, and feeling of
suffocation. Severe breathing difficulties may occur which may be
delayed in onset. Severe exposure may lead to pneumonitis and
pulmonary edema and may be fatal. Repeated or prolonged exposure
may result in reduced pulmonary capacity and dental erosion., Skin:
Contact with liquid chlorine may cause serious burns, blistering
and tissue destruction. Chlorine vapors can cause irritation,
burning and blisters., Eyes: Exposure to chlorine gas may cause
severe eye damage. Direct contact of the eyes with liquid chlorine
will produce serious eye burns even blindness., Summary of Chronic
Health Hazards: Repeated or prolonged exposure to chlorine may
cause corrosion of the teeth and skin irritation. A study of 600
diaphragm cell workers exposed to 0.006 to 1.42 ppm, showed no
statistically significant increase in abnormal chest x-rays, ECG's
or pulmonary function tests., Summary of Toxic Effects: Inhalation
is expected to be the primary route of occupational exposure to
chlorine. Chlorine liquid is corrosive to the eyes, mucous
membranes and skin. At normal atmospheric pressure and temperature,
liquid chlorine readily vaporizes to gas. Chlorine gas causes
severe irritation of the eyes and respiratory tract with eye
injury, restlessness, shortness of breath, cough, choking
sensation, sneezing, running nose, chest pain, dizziness, headache,
nausea, cyanosis (lack of oxygen in the blood) and respiratory
failure. Following respiratory tract injury, onset of severe
breathing difficulties, including bronchitis, lung edema
(accumulation of fluid in the lungs) and pneumonia, may be delayed
and life threatening. High concentrations of chlorine over a short
period of time may aggravate pre-existing heart conditions, and
cause congestive heart failure. At high concentrations, chlorine
gas irritates the skin and can produce sensations of burning and
pricking of the skin, with inflammation and blister formation.
Exposure to concentrations as low as 5-10 ppm is reported to cause
severe irritation of the eyes, nose and respiratory tract which is
intolerable after a few minutes. Overexposure to chlorine can
trigger asthma attacks in susceptible individuals. Due to potential
for chlorine to produce severe respiratory tract irritation and
aggravate heart conditions, workers with lung disease, compromised
lung function or cardiovascular conditions should have limited
exposure to this material. The threshold odor concentration of
chlorine is reported to range from 0.3-3.5 ppm. Repeated exsposure
to chlorine can result in loss of the ability to detect the odor of
chlorine. Chronic overexposure to chlorine has been associated with
erosion of the teeth, chest pain, hemoptysis (coughing up blood),
nose bleeds, chronic bronchitis and an increased susceptibility to
tuberculosis. NFPA Rating: Health - 4; Fire - 0; Reactivity - 0

Medical Cond Aggravated by Exposure:
======================= First Aid Measures =======================
First Aid:Ingestion: Never give anything by mouth to an unconscious
person. If swallowed, DO NOT INDUCE VOMITING. Give large quantities
of water. If vomiting occurs spontaneously, keep airway clear and
give more water. GET MEDICAL ATTENTION IMMEDIATELY.Inhalation: If a
person breathes in large amounts of chlorine, move the exposed
person to fresh air at once. If breathing has stopped, perform
artifical respiration. Keep the affected person warm and at rest.
GET MEDICAL ATTENTION AS SOON AS POSSIBLE.Skin: If liquid chlorine
or high concentrations of chlorine gas get on the skin, immediately
flush the contaminated skin with water for at least 15 minutes. If
liquid chlorine or high concentrations of chlorine gas penetrate
through the clothing, remove clothing under a safety shower and
continue to wash the skin for at least 15 minutes. If irritation is
present after washing, GET MEDICAL ATTENTION. Do not apply greases
unless ordered by a physician. Wash clothing before reuse. Destroy
contaminated shoes. Eyes: If liquid chlorine or high concentrations
of chlorine gas get into the eyes, flush eyes immediately with a
directed stream of water for at least 15 minutes while forcibly
holding eyelids apart to ensure complete irrigation of all eye and
lid tissue. Do not attempt chemical neutralization of any kind. GET
MEDICAL ATTENTION IMMEDIATELY. Contact lenses should not be worn
when working with chlorine.Medical Conditions Generally Aggravated
by Exposure: : Chlorine is a respiratory irritant. Persons with
asthma, bronchitis, emphysema or other lung diseases, and chronic
nose, sinus or throat conditions may be at increased risk from
exposure.Note to Physicians: No known antidote. Treatment for
inhalation is symptomatic and supportive. Keep patient at rest
until respiratory symptoms subside. Sedation for apprehension or
restlessness may be considered as well as diuretics and antibiotics
to alleviate edema and protect against secondary infection.
Administer oxygen under exhalation pressure not exceeding 4 cm
water for 15 minutes each hour until symptoms subside (except in
presence of impending or existing cardiovascular failure). Steroid
therapy, if given early, has been reported effective in preventing
pulmonary edema. It is recommended that anyone exposed to chlorine
gas by inhalation obtain a chest x-ray to check for pulmonary
edema.
===================== Fire Fighting Measures =====================
Flash Point:Non-flammable
Extinguishing Media:Use water spray to keep fire-exposed containers
cool, but avoid area where chlorine is leaking. Use extinguishing
media as appropriate for materials in the surrounding fire.
Fire Fighting Procedures:Firefighters MUST use self contained breathing
equipment, eye protection and full protective clothing when
fighting fires in which chlorine is involved. Use water spray to
keep fire-exposed containers cool, but avoid area where chlorine is
leaking.
Unusual Fire/Explosion Hazard:Noncombustible in air, many metals ignite
in presence of chlorine-for example, steel at about 4850癋 may
react to cause fire and/or explosion upon contact with turpentine,
ether, ammonia, hydrocarbons, certain metal hydrides, carbides,
nitrides, oxides, sulfides, phosphides, easily oxidized materials,
orgainic materials or other flammables. Forms Hydrogen Chloride
when contacted with water.
================== Accidental Release Measures ==================
Spill Release Procedures:In event of leak or spill, keep up wind,
notify safety personnel, provide ventilation, wear full protective
equipment and shut off supply at source. Keep combustibles (wood,
paper, oil, etc.) away from spilled material. DO NOT apply water to
point leak or spill area. Exclude from area all except specially
trained, assigned personnel with approved equipment and clothing.
Uncontrollable leaks may require evacuation of surrounding area.
Keep material out of water courses and sewers. If source of leak is
a cylinder and the leak cannot be stopped inplace, remove the
leaking cylinder to a safe place in the open air, and repair the
leak or allow the cylinder to empty through a reducing agent, such
as caustic soda, soda ash, or hydrated lime solutions. Isolate area
until gas has dispersed.
Neutralizing Agent:
====================== Handling and Storage ======================
Handling and Storage Precautions:Store chlorine containers in well
ventilated areas of low fire potential, away from incompatible
materials and away from sources of heat and ignition. Protect
containers from weather and physical damage. Regularly test and
inspect piping and containment used for chlorine service. Liquid
levels should be less than 85% of tank or cylinder capacity. Spills
of chlorine of 10 or more pounds must be reported to the National
Response Center (800-424-8802).
Other Precautions:Provide special training to workers handling
chlorine. Regularly test and inspect piping and containment used
for chlorine service.
============= Exposure Controls/Personal Protection =============
Respiratory Protection:Minimum respiratory protection required with a
gas concentration above 1 ppm but less than 25 ppm: a chemical
cartridge respirator with a full facepiece and cartridge(s); a gas
mask with a chin-style or a front- or back-mounted canister; any
supplied-air respirator with a full facepiece, helmet, or hood; any
self-contained breathing apparatus with a full facepiece. In a gas
concentration greater than 25 ppm, a self-contained breathing
apparatus with a full facepiece operated in pressure-demand or
other positive pressure mode must be used. Only NIOSH-approved or
MSHA-approved equipment providing protection against chlorine
should be used.
Ventilation:Provide general and local exhaust ventilation to meet TLV
of 0.5 ppm. Provide suitable venting for low lying areas. Use
enclosed, isolated processing and handling whenever possible.
Eye Protection:Employees should be required to use splash-proof safety
goggles and face shield where there is any possibility of liquid
chlorine contacting the eyes. Contact lenses must not be worn when
working around chlorine.
Other Protective Equipment: Employees should be required to use
impervious clothing, rubber or neoprene gloves, face shields
(eight-inch minimum) and other appropriate protective clothing
necessary to prevent any possibility of skin contact with liquid
chlorine, and to prevent the skin from becoming frozen from contact
with vessels containing liquid chlorine. Eyewash stations and
safety showers must be available in the immediate work areas.
Work Hygienic Practices:Avoid contact with skin and avoid breathing
vapors. Do not eat, drink, or smoke in work area. Wash hands before
eating, drinking, or using restroom.

================= Stability and Reactivity Data =================
Stability Indicator/Materials to Avoid:Stable
Chlorine is a powerful oxidizing agent which reacts violently with a
variety of substances over a broad range of conditions including
reducing agents and combustible materials. It should be kept away
from materials such as acetylene, turpentine, other hydrocarbons,
ammonia, hydrocarbons, certain metal hydrides, nitrides, oxides,
sulfides, phosphides, easily oxidized materials, organic materials,
hydrogen, ether, powdered metals, sulfur, and aluminum. Chlorine
reacts with hydrogen sulfide and water forming hydrochloric acid.
It combines with carbon monoxide and sulfur dioxide to form
phosgene and sulfuryl chloride, respectively, which are toxic and
corrosive substances.
Stability Condition to Avoid:The presence of moisture in gaseous and
liquid chlorine increases corrosive attack on most common metals.
Will react with water or steam to produce toxic and corrosive fumes
of hydrogen chloride.
Hazardous Decomposition Products:Chlorine does not decompose but reacts
violently to form Hydrochloric Acid and other potentially toxic
and/or corrosive substances. Chlorine is stable in steel containers
at room temperature when dry. Intense local heat on steel walls can
cause the steel to react and glow in presence of chlorine.
Conditions to Avoid Polymerization:
=================== Toxicological Information ===================
Toxicological Information:Toxicology Testing Data: Numerous studies
have been conducted to determine the potential chlorine has to
cause chronic effects. In rats exposed to concentrations up to 9
ppm for 6 hours a day, 5 days a week for 6 weeks, decreases in body
weight and inflammation of the respiratory tract were observed. At
exposures of 3 and 9 ppm changes in the liver and kidneys were also
noted. Rabbits and guinea pigs exposed to 1.7 ppm for 9 months
showed weight loss and a decreased resistance to disease. No
adverse effects were observed in rabbits and guinea pigs at levels
of 0.7 ppm. Guinea pigs exposed to 1.6 ppm for 5 hours a day, for
47 days and injected with tuberculosis (bacteria) displayed shorter
life cycles then those exposed to just one of the agents. Rhesus
monkeys exposed to concentrations up to 2.3 ppm for 6 hours a day,
5 days a week for one year did not exhibit any signs of chronic
toxicity. The hazard at different concentrations is reported to be
as follows: 0.2-0.5 ppm=No toxic, long term effect 1-3 ppm=Definite
odor: irritation of eyes and nose 5-8 ppm=Throat, eye, and mucous
membrane irritation 30 ppm=Intense coughing fits 34-51 ppm=Lethal
in 1 to 1.5 hours exposure 40-60 ppm=Exposure for 30-60 minutes
without effective respiration may cause bronchitis, pulmonary edema
or bronchopneumonia 100 ppm=May be lethal after 50 minutes of
exposure (estimated) 430 ppm=Lowest concentration known to cause
lethality after 30 minutes of exposure 1000 ppm=May be fatal with a
few deep breaths Reproductive Toxicity: Two studies have been
conducted to assess the ability of chlorine to cause reproductive
effects. Rabbits exposed by inhalation to concentrations up to 1.5
ppm and rats exposed by ingestion to highly chlorinated drinking
water daily for seven generations did not display any adverse
reproductive effects. NSF Standard 60 Maximum Use 30 mg/L
==================== Disposal Considerations ====================
Waste Disposal Methods:Chlorine gas will disperse to the atmosphere
leaving no residue. When possible, move leaking container to an
isolated area. Position to release gas, not liquid. One volume of
liquid chlorine is equivalent to about 460 volumes of gas. Absorb
in alkaline solution of caustic soda, soda ash, or hydrated lime.
Liquid or solid residues must be disposed of in a permitted waste
management facility. Consult federal, state, or local disposal
authorities for approved procedures.
