3. Hazards Identification
EMERGENCY OVERVIEW
Product is an odorless, colorless gas which may cause asphyxiation in high concentrations. Gas may
accumulate in confined or poorly ventilated areas, displacing oxygen and causing unconsciousness or
death. Use only with adequate ventilation. Long-term exposure to carbon monoxide may adversely
affect fetal development.

EYE EFFECTS:

SKIN EFFECTS:

INGESTION EFFECTS:
Not anticipated; product is a gas.
INHALATION EFFECTS:
Nitrogen acts as a simple asphyxiant displacing the oxygen content in the air necessary for life. Carbon
monoxide is a chemical asphyxiant . The affinity of hemoglobin for carbon monoxide is 200-300 times greater
than its affinity for oxygen; thus hemoglobin will preferentially bind to carbon monoxide and asphyxiation can
occur in the presence of atmospheric oxygen.
The affinity of hemoglobin for carbon monoxide is 200-300 times greater than its affinity for oxygen thus
hemoglobin will preferentially bind to carbon monoxide and asphyxiation can occur in the presence of sufficient
atmospheric oxygen. An LCLo of 4000 ppm for 30 minutes was reported for human inhalation of carbon
monoxide (man).
SUBCHRONIC:
Inhalation studies which exposed monkeys to 750 ppm propane for 90 consecutive days showed no observed
abnormalities or toxicity.
OTHER:
Carbon monoxide inhalation by pregnant animals has produced teratogenic effects.
SIGNS & SYMPTOMS:
Dependent on levels and duration of exposure, symptoms of overexposure may include all or none of the
following: dizziness, tingling, headache, shortness of breath, emotional instability, defective memory, fatigue,
nausea and vomiting, coma and death from respiratory arrest.
CHRONIC:
Evidence suggests that long-term exposure to carbon monoxide may adversely affect the fetus due to the
presence of elevated levels of carboxyhemoglobin and decreased oxygen content in the blood.

4. First Aid Measures
EYE:
Flush eyes with large amounts of water for at least 15 minutes holding eyelids open to ensure adequate rinsing.
If irritation persists, seek immediate medical attention.
SKIN:
Irritation is not anticipated.
INGESTION:
Not anticipated; product is a gas.
INHALATION:
PROMPT REMOVAL FROM THE CONTAMINATED AREA AND IMMEDIATE MEDICAL ATTENTION
IS MANDATORY IN ALL CASES OF OVEREXPOSURE. RESCUE PERSONNEL SHOULD BE
EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS.
Immediately remove to fresh air. If breathing is difficult, administer oxygen. If breathing has stopped, give
artificial respiration. Seek immediate medical attention. The administering of the oxygen at an elevated
pressure (up to 2 to 2.5 atmospheres) has shown to be beneficial as has treatment in a hyperbaric chamber. The
physician should be informed that the patient may have inhaled toxic quantities of carbon monoxide.

FIRE AND EXPLOSION HAZARDS:
The majority of this product constitutes a nonflammable, inert gas. This product does contain 2 % carbon
monoxide and 0.15% propane, which are flammable however the percent weight of carbon monoxide and
propane in this mixture are well below the Lower Explosive range (12 and 2.1%, respectively). Containers may
rupture or explode from pressure when exposed to heat or flames.
EXTINGUISHING MEDIA:
Any - carbon dioxide, water, dry chemical ,foam or fog. Use media appropriate for surrounding fire.
FIRE FIGHTING INSTRUCTIONS:
Continue to cool surrounding containers until well after flames are extinguished. Firefighters should wear a full-
facepiece, NIOSH/MSHA-approved self-contained breathing apparatus (SCBA) operated in positive pressure
mode and full turnout gear.

6. Accidental Release Measures
Isolate hazard area, evacuate personnel and deny entry to unauthorized/unprotected individuals. Extinguish all
ignition sources and ventilate closed spaces and low areas. Personnel entering area should wear appropriate
protective equipment including respiratory protection suitable for unknown concentrations. Personnel should
not re-enter hazard area until carbon monoxide has sufficiently dispersed and adequate oxygen is re-established.
If a leak is in user鈥檚 equipment, be certain to purge piping with an inert gas prior to attempting repairs. If leak is
in container of container valve, contact the appropriate emergency telephone number listed in Section 1 or call
your closest BOC location.
7. Handling and Storage
Electrical classification: Nonhazardous.
Use only in well-ventilated areas. Valve protection caps must remain in place unless container is secured with
valve protection outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for
cylinder movement. Use a pressure reducing regulator when connecting cylinder to lower pressure (< 3000
psig) piping or systems. Do not heat cylinder by any means to increase the discharge rate of product from the
cylinder. Use a check valve or trap in the discharge line to prevent hazardous back flow into the cylinder. For
additional recommendations, consult Compressed Gas Association鈥檚 Pamphlets P-1.
Protect cylinders from physical damage. Store in cool, dry, well-ventilated area of non-combustible construction
away from heavily trafficked areas and emergency exits. Do not allow the temperature where cylinders are
stored to exceed 125 掳F. Cylinders should be stored upright and firmly secured to prevent FALLING OR
BEING KNOCKED OVER. Use a 鈥渇irst in-first out鈥? inventory system to prevent full cylinders being stored for
excessive periods of time.
Stationary customer site vessels should operate in accordance with the manufacturer's and BOC鈥檚 instruction. Do
not attempt to repair, adjust or in any other way modify the operation of these vessels. If there is a malfunction
or other type of operations problem with the vessel, contact the closest BOC location immediately.
Never carry a compressed gas cylinder or a container of a gas in cryogenic liquid form in an enclosed space such
as a car trunk, van or station wagon. A leak can result in a fire, explosion, asphyxiation or a toxic exposure.

11. Toxicological Information
Used as an ingredient in a deodorant product as an aerosol propellant propane failed to cause skin irritation in
125 volunteers who applied the product twice daily for 12 weeks.
REPRODUCTIVE EFFECTS:
Experimental mutagenic data exists for carbon monoxide.
Bronchopneumonia, brain injury with motor and mental effects, skin lesions, vital organ damage, and central
nervous system damage have been reported in infants born to women who have been acutely exposed to high
concentrations of carbon monoxide.
Acute exposures to propane 250, 500, or 1000 ppm for periods of 1 M to 8 hr did not produce untoward
physiological effects.
12. Ecological Information
ENVIRONMENTAL FATE:
A photochemical model indicated that increased CO emissions will generally suppress OH (negative
coefficients) and increase O3 (positive coefficients) but these trends may be opposed by climate change and
stratospheric O3 depletion.
Volatilization is expected to be the dominant fate process for propane in both soil and water with hydrolysis and
biodegradation occurring to a lesser extent. Direct photolysis of propane in the atmosphere is not anticipated.
ECOTOXICITY:
No data available.
