If in Eyes: Avoid eye
contact. Direct contact with liquefied/
pressurized gas or frost particles may cause
frostbite and possibly severe and permanent eye
damage.
If on Skin: Avoid direct skin
contact. Direct contact with
liquefied/pressurized gas or frost particles may
cause severe burns or frostbite (“cold”
burns).
If Inhaled: Avoid inhalation of
high concentrations of gas. Acute overexposure
may result in irritation of the throat and
lungs. High concentrations in confined areas can
displace oxygen and can cause dizziness,
unconsciousness, and even death with longer
exposure. Long term exposure to this product may
cause symptoms of drowsiness, dullness,
numbness, headache, dizziness, nausea and
increase heart rate.
Ingestion: Not
applicable by this route of exposure. This
product is regarded as having a low order of
toxicity.
Health Effects Data: Inhalation of
this product at high concentrations is capable
of producing damage to the central nervous
system, cardiovascular system, respiratory
system, and skin; however, the heart appears to
be the most sensitive organ. Choice-R420A is not
carcinogenic, mutagenic, a skin sensitizer, or a
reproductive toxin according to the OSHA Hazard
Communication Standard (HCS) {29 CFR
1910.1200}. |

Fire & Explosion Hazard
Data |
Flash Point:
Non-Flammable - - Flammable Limits LEL:
N/A UEL: N/A
Extinguishing
Media: Extinguishing Media is generally not
necessary.
This material is nonflammable.
Special Fire
Fighting Procedures: Use water to keep fire
exposed containers cool and to protect personnel
during shutoff. If possible, stop the flow of
gas or vapor, then fight fire according to types
of burning material. If flow cannot be safely
shut off, allow fire to burn itself out. Cool cylinders with water
spray until well after fire is out. Upon
exposure to intense heat or flame, container may
vent rapidly or explode.
Unusual Fire and
Explosion Hazards: Gas vapors can collect and
remain in low spots even after the source of gas
has been eliminated. Contact with certain
reactive metals may result in formation of
explosive or exothermic reactions under specific
conditions (e.g. very high temperatures and/or
appropriate pressures). Caution: Contents are
under pressure and can explode when exposed to
heat or
flames. |

Reactivity Data |
Stability:
Stable
Incompatibility (Materials To Avoid):
Finely divided metals, magnesium and alloys
containing more than 2% magnesium. Can react
violently in the presence of alkali or alkali
metals such as sodium, potassium or
barium.
Hazardous Polymerization:
NONE
Conditions to avoid: High temperatures,
above 173.30 F
Hazardous Decomposition Products: CO,
CO2, Hydrogen chloride gas,
hydrofluoric acid fumes, halogen
acids |
| Section
VII |
Emergency/ First Aid
Procedures: |
If in Eyes: Flush
with water. (At least 15 minutes) Get medical
attention if irritation persists.
If on Skin:
If skin is exposed to liquified/ pressurized gas
or frost particles, soak with warm water. If
frostbite occurs, do not put frozen area into
hot water or place in front of a heat
source.
If Swallowed: Seek medical help. Do
not induce vomiting.
If Inhaled: Remove
person to fresh air. Seek medical help if
irritation persists. If chronically abused and
breathing stops, give artificial
respiration. |
| Section VIII |
Precautions For Safe
Handling And Use |
If Material is
Released Or Spilled: Evacuate all personnel from
effected area. Use appropriate protective
equipment. If leak is in user’s equipment, be
certain to purge piping with an inert gas prior
to attempting repairs.
Waste Disposal Method:
Dispose of according to local and state laws.
Wrap in newspaper and dispose of in trash.
Discarded product is not a hazardous waste under
RCR, 40 CFR 261. This
material is not specifically listed as hazardous
waste but can be classified as hazardous waste
if contaminated with other hazardous
materials. |
| Section IX |
Special Handling/
Precautions |
| Storage: Never expose
cylinders to excessive heat. Cylinders should be
stored in a well ventilated area. Storage should
not exceed 500 C or 1300 F and should be free of
oxidizers or corrosive materials. Handling: Do
not drag, roll, or slide cylinders: Secure
cylinder at all times. Use
separate control valves or pressure reducing
regulators to safely discharge rate. Compressed
gas cylinders must not be filled by the owner or
with the owner’s consent. This is a violation of
federal
law. |
| Section X |
