HAZARDS IDENTIFICATION |
|
Warning: |
|
Flammable
liquid gas under pressure. |
|
Can
form explosive mixtures with air. |
|
Potential
Health Effects Information: |
|
Inhalation: |
|
Simple
asphyxiant. It should be noted that before suffocation could occur, the
lower |
|
flammability
limit of propane in air would be exceeded; possibly causing both an |
|
oxygen-deficient
and explosive atmosphere. Exposure to concentrations (> 10%) |
|
may
cause dizziness. Exposure to atmospheres containing 8-10% or less oxygen |
|
will
bring about unconsciousness without warning, and so quickly that the
individuals |
|
cannot
help or protect themselves. Lack of sufficient oxygen may cause serious |
|
Eye
Contact: |
|
Contact
with liquid or cold vapor can cause freezing of tissue. |
|
Skin
Contact: |
|
Contact
with liquid or cold vapor can cause frostbite. |

Medical
Conditions Aggravated By |
|
None. |
|
Other
Effects Of Overexposure: |
|
None. |
|
Carcinogenicity: |
|
Propane
is not listed by NTP, OSHA or IARC. |
|
Inhalation: |
|
Persons
suffering from lack of oxygen should be removed to fresh air. If victim
is |
|
not
breathing, administer artificial respiration. If breathing is difficult,
administer |
|
oxygen.
Obtain prompt medical attention. |
|
Eye: |
|
Contact
with liquid or cold vapor can cause freezing of tissue. Gently flush
eyes |
|
with
lukewarm water. Obtain medical attention immediately. |
|
Skin: |
|
Contact
with liquid or cold vapor can cause frostbite. Immediately warm affected |
|
area
with lukewarm water not to exceed 105°F (40°C). |

Extinguishing
Media: |

CO2,

source is shut off. |
|
Fire
Fighting Instructions: |
|
Evacuate
all personnel from danger area. Immediately cool container with water |
|
spray
from maximum distance, taking care not to extinguish flames. If flames
are |
|
accidentally
extinguished, explosive re-ignition may occur. Stop flow of gas if |
|
without
risk while continuing cooling water spray. |
|
Fire
And Explosion Hazards: |
|
Propane
is easily ignited. It is heavier than air, therefore, it may collect in
low areas |
|
or
travel along the ground where an ignition source may be present.
Pressure in a |
|
container
can build up due to heat, and it may rupture if pressure relief devices |
|

|

|
Sensitivity
To Static Discharge: |
|

container should be grounded. |
|
Sensitivity
To Mechanical Impact: |
|
None. |
06.
ACCIDENTAL RELEASE MEASURES |
|
Evacuate: |
|
Evacuate
the immediate area. Eliminate any possible sources of ignition, and |
|
provide
maximum explosion-proof ventilation. Shut off source of propane, if |
|
possible.
If leaking from cylinder, or valve, contact your supplier. Never enter a |
|
confined
space or other area where the concentration is greater than 10% of the |
|
lower
flammable limit which is 0.22%. |
|
Storage: |
|
Specific
requirements are listed in NFPA 58. Cylinder storage locations should be |
|
well-protected,
well-ventilated, dry, and separated from combustible materials. |
|
Cylinders
should never knowingly be allowed to reach a temperature exceeding |
|
125°F
(52°C). Cylinders of propane should be separated from oxygen cylinders
or |
|
other
oxidizers by a minimum distance of 20 ft., or by a barrier of
non-combustible |
|
material
at least 5 ft. high having a fire resistance rating of at least ½ hour.
Full and |
|
empty
cylinders should be segregated. Use a first-in, first-out inventory
system to |
|
prevent
full containers from being stored for long periods of time. |
|
Cylinders
should be stored upright with valve protection cap in place and firmly |
|
secured
to prevent falling or being knocked over. Protect cylinders from
physical |
|
damage;
do not drag, roll, slide or drop. Use a suitable hand truck for cylinder |
|
movement.
Post "No Smoking or Open Flames" signs in the storage areas.
There |
|
should
be no sources of ignition. All electrical equipment should be explosion
proof |
|
in
the storage and use areas. Storage areas must meet national electric
codes for |
|
Handling: |
|
Propane
is heavier than air and may collect in low areas that are without proper |
|
ventilation.
Leak check system with leak detection solution, never with flame. If |
|
user
experiences difficulty operating cylinder valve, discontinue use and
contact |
|
supplier.
Never insert an object (e.g., wrench, screwdriver, pry bar, etc.) into
valve |
|
cap
openings. Doing so may damage valve, causing a leak to occur. Use an |
|
adjustable
strap wrench to remove over-tight or rusted caps. Non-sparking tools |
|
should
be used. Never strike an arc on a compressed gas cylinder or make a |
|
cylinder
a part of an electrical circuit. Electrically bond and ground cylinder
when |
|
transferring
liquid product. For additional precautions in using propane see Section |
08.
EXPOSURE CONTROLS - PERSONAL PROTECTION |
|
