3 HAZARDS IDENTIFICATION
Emergency Overview
Colorless liquified gas with faint ether odor.
DANGER!
FLAMMABLE LIQUID AND GAS UNDER PRESSURE, OVERHEATING OR OVERPRESSURIZING MAY CAUSE
GAS RELEASE OR VIOLENT CYLINDER BURSTING. MAY DECOMPOSE ON CONTACT WITH FLAMES OR
EXTREMELY HOT METAL SURFACES TO PRODUCE TOXIC AND CORROSIVE PRODUCTS. VAPOR REDUCES
OXYGEN AVAILABLE FOR BREATHING AND IS HEAVIER THAN AIR. HARMFUL IF INHALED AND MAY CAUSE
HEART IRREGULARITIES, UNCONSCIOUSNESS OR DEATH. LIQUID CONTACT WITH EYES OR SKIN MAY
CAUSE FROSTBITE.
Potential Health Effects
Skin contact and inhalation are expected to be the primary routes of occupational exposure to this material. Based on
single exposure animal tests, this material is considered to be practically non-toxic if inhaled. However, exposure to
gas of this material at high concentrations may effect the nervous system and produce a rapid anesthetic effect. The
dense vapor of this material can reduce the oxygen available for breathing and produce symptoms such as headache,
dizziness, drowsiness, cyanosis and lack of muscle control followed by collapse. Prolonged exposure to and oxygen-
deficient atmosphere may be fatal. Inhalation of this material may cause an increase in the sensitivity of the heart to
adrenaline, which could result in irregular heart beats and reduced heart function. Workers with heart disease or
compromised heart function should limit exposure to this material.

4 FIRST AID MEASURES
IF IN EYES, immediately flush with plenty of water. Get medical attention if irritation persists.
IF ON SKIN, Flush exposed skin with lukewarm water (not hot), or use other means to warm skin slowly. Get
medical attention if frostbitten by liquid or if irritation occures.
IF SWALLOWED, Not applicable - product is a gas at ambient temperatures.
IF INHALED, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention. Do not give adrenaline, epinephrin or similar drugs following exposure to this
product.
5 FIRE FIGHTING MEASURES
Fire and Explosive Properties
Auto-Ignition Temperature NE
Flash Point NA - GAS Flash Point Method
Flammable Limits- Upper 15.5
6.9
Lower
Extinguishing Media
Use water spray, water fog, carbon dioxide, or dry chemical.
Fire Fighting Instructions
Stop the flow of gas if possible. Use water spray on person making shut-off. Fire fighters and others who may
be exposed to products of combustion should wear full fire fighting turn out gear (full Bunker Gear) and self-
contained breathing apparatus (pressure demand NIOSH approved or equivalent). Fire fighting equipment
should be thoroughly decontaminated after use.
Fire and Explosion Hazards
May decompose on contact with flames or extremely hot metal surfaces to produce toxic and corrosive
products. Liquid and gas under pressure, overheating or overpressurizing may cause gas release and/or violent
cylinder bursting. Container may explode if heated due to resulting pressure rise. Some mixtures of HCFCs
and/or HFCs, and air or oxygen may be combustible if pressurized and exposed to extreme heat or flame.
6 ACCIDENTAL RELEASE MEASURES
In Case of Spill or Leak
Use Halogen leak detector or other suitable means to locate leaks or check atmosphere. Keep upwind.
Evacuate enclosed spaces and disperse gas with floor-level forced-air ventilation. Exhaust vapors outdoors.
Do not smoke or operate internal combustion engines. Remove flames and heating elements.

7 HANDLING AND STORAGE
Handling
Do not get in eyes, on skin or clothing. Avoid breathing gas. Keep container closed. Use only with adequate
ventilation. Wash thoroughly after handling. Keep away from heat, sparks and flame. Empty container may
contain hazardous residues. Do not reuse container. Do not cut, grind or weld on or near containers -
explosion hazard. Use explosion proof equipment. Use grounding and bonding connection when transferring
material to prevent static discharges, fire or explosion.
Storage
Do not apply direct flame to cylinder. Do not store cylinder in direct sun or expose it to heat above 120 F. Do
not drop or refill this cylinder. Keep away from heat, sparks and flames.
8 EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering Controls
Investigate engineering techniques to reduce exposures below airborne exposure limits. Provide ventilation if
necessary to control exposure levels below airborne exposure limits (see below). If practical, use local
mechanical exhaust ventilation at sources of air contamination such as open process equipment.
Eye / Face Protection
Where there is potential for eye contact, wear chemical goggles and have eye flushing equipment available.
Skin Protection
Wear appropriate chemical resistant protective clothing and chemical resistant gloves to prevent skin contact.
Consult glove manufacturer to determine appropriate type glove material for given application. Rinse
contaminated skin promptly. Wash contaminated clothing and clean protective equipment before reuse. Wash
skin thoroughly after handling.
Respiratory Protection
Avoid breathing gas. When airborne exposure limits are exceeded (see below), use NIOSH approved
respiratory protection equipment appropriate to the material and/or its components (full facepiece
recommended). Consult respirator manufacturer to determine appropriate type equipment for a given
application. Observe respirator use limitations specified by NIOSH or the manufacturer. For emergency and
other conditions where exposure limit may be significantly exceeded, use an approved full face positive-
pressure, self-contained breathing apparatus or positive-pressure airline with auxiliary self-contained air supply.
Respiratory protection programs must comply with 29 CFR 搂 1910.134.
Airborne Exposure Guidelines for Ingredients
Exposure Limit Value
1-Chloro-1,1-difluoroethane, HCFC-142b
WEEL TWA - 1000 ppm 4100 mg/m3
-Only those components with exposure limits are printed in this section.
-Skin contact limits designated with a "Y" above have skin contact effect. Air sampling alone is insufficient to accurately quantitate
exposure. Measures to prevent significant cutaneous absorption may be required.
-ACGIH Sensitizer designator with a value of "Y" above means that exposure to this material may cause allergic reactions.

11 TOXICOLOGICAL INFORMATION
Toxicological Information
Inhalation exposure causes an initial stimulation and then depression of the central nervous system.
Symptoms in animals include loss of equilibrium, tremors, convulsions and narcosis. Death was usually
attributed to respiratory failure. The lowest lethal concentration for a 30 minute exposure in rats was 500,000
ppm. Animals that died from inhalation exposure, generally showed lung irritation. Following inhalation
exposure to this material at 200,000 ppm effects on the lungs were noted in rats; 100,000 ppm was severely
irritating to the lungs and lethal to all rats within 9 exposures; repeated exposure to10,000 ppm produced no
effects in rats and dogs. Long term exposure to 20,000 ppm was reported to be the (NOEL) level in rats. No
birth defects were noted in rats exposed by inhalation during pregnancy at levels up to 10,000 ppm. The results
of tests for genetic changes were mixed.
Inhalation exposure to this material can cause cardiac arrhythmias and effects on the cardiac and respiratory
system in dogs. Dogs treated with adrenalin then exposed by inhalation to this material at 50,000 ppm for 5
minutes exhibited cardiac sensitization. Following repeated inhalation exposure to this material no increases in
urinary fluoride was reported and this material was not detected in the tissues.
Single exposure (acute) studies indicate:
Inhalation - Practically Non-Toxic to Mice (30 min-LC50 300,000 ppm)
Inhalation - Practically Non-Toxic to Mice (2 hr-LC50 368,000 ppm)
