| Hazard Information | Back Directory | [General Description]
CHLORODIFLUOROMETHANE(75-45-6) is a colorless gas with an ethereal odor. CHLORODIFLUOROMETHANE(75-45-6) is shipped as a liquefied gas under its own vapor pressure. CHLORODIFLUOROMETHANE(75-45-6) is noncombustible. CHLORODIFLUOROMETHANE(75-45-6) can asphyxiate by the displacement of air. Contact with the liquid can cause frostbite. Toxic gases can be produced in fires involving this material. Exposure of the container to prolonged heat or fire may cause CHLORODIFLUOROMETHANE(75-45-6) to rupture violently and rocket. | [Reactivity Profile]
CHLORODIFLUOROMETHANE is incompatible with the following: Alkalis, alkaline earth metals (e.g., powdered aluminum, sodium, potassium, zinc) . | [Air & Water Reactions]
The liquefied gas poured into water can be violently explosive. This is due to the phase transition from superheated liquid to vapor. | [Hazard]
Asphyxiant. Central nervous system
impairment, cardiac sensitization. Questionable
carcinogen. | [Health Hazard]
Inhalation at greater than 10% concentration in air may cause narcosis. Liquid may cause frostbite. | [Potential Exposure]
Chlorodifluoromethane is used as an
aerosol propellant, refrigerant, and low-temperature solvent.
It is used in the synthesis of polytetrafluoroethylene
(PTFE). | [Fire Hazard]
Special Hazards of Combustion Products: Decomposition gases are toxic and irritating. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
If frostbite has occurred, seek medical attention immediately; do NOT rub the affected areas or flush them with
water. In order to prevent further tissue damage, do NOT
attempt to remove frozen clothing from frostbitten areas. If
frostbite has NOT occurred, immediately and thoroughly
wash contaminated skin with soap and water.
| [Shipping]
UN1018 Chlorodifluoromethane, Hazard Class:
2.2; Labels: 2.2-Non-flammable compressed gas. Cylinders
must be transported in a secure upright position, in a wellventilated truck. Protect cylinder and labels from physical
damage. The owner of the compressed gas cylinder is the
only entity allowed by federal law (49CFR) to transport
and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express
written permission of the owner.
| [Incompatibilities]
The liquefied gas poured into water can
be violently explosive. This is due to the phase transition
from superheated liquid to vapor. Chlorodifluoromethane reacts violently with alkalies and alkaline earth
metals; powdered aluminum; sodium, potassium, and zinc;
causing fire and explosion hazard. Moisture and rust cause
slow decomposition, forming toxic gases. Attacks some
plastics, rubber, and coatings. Decomposes in heat forming
fumes of chlorine, hydrogen chloride, HF, and phosgene.
Attacks magnesium and its alloys. | [Description]

ChEBI: Chlorodifluoromethane is a hydrochlorofluorocarbon. | [Carcinogenicity]
In one study, an oral dose of
300mg of HCFC 22/kg of body weight was given to
36 male and 36 female rats 5 days/week for 52 weeks.
The rats were held for 125 weeks compared to controls.
There was no evidence of any treatment related increase in
tumors. In an inhalation study 60 male and
60 female rats were exposed by inhalation to levels of
5000 ppm of HCFC 22. The exposures were 4 h/day,
5 days/week for 104 weeks (rats) or 78 weeks (mice). | [storage]
Nonflammable gas. Color Code—Green: Generalstorage may be used. Prior to working with chlorodifluoromethane you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area. Sources of ignition, such as smoking andopen flames, are prohibited where this chemical is used,handled, or stored in a manner that could create a potentialfire or explosion hazard. Procedures for the handling, use,and storage of cylinders should be in compliance withOSHA 1910.101 and 1910.169, as with the recommendations of the Compressed Gas Association. A regulated,marked area should be established where this chemical ishandled, used, or stored in compliance with OSHAStandard 1910.1045. |
