6. ACCIDENTAL RELEASE MEASURES
LEAK RESPONSE: Due to the small size and content of the cylinder, an accidental release of this product presents
significantly less risk of an oxygen-deficient environment and other safety hazards than a similar release from a
larger cylinder. However, as with any chemical release, extreme caution must be used during emergency response
procedures. In the event of a release in which the atmosphere is unknown, and in which other chemicals are
potentially involved, evacuate immediate area. Such releases should be responded to by trained personnel using
pre-planned procedures. Proper protective equipment should be used. In case of a leak, clear the affected area and
protect people. For emergency disposal, secure the cylinder and slowly discharge the gas to the atmosphere in a

well-ventilated area or outdoors. Allow the gas mixture to dissipate. If necessary, monitor the surrounding area (and
the original area of the release) for oxygen and the level of 1,3-Butadiene. Oxygen levels must be above 19.5% and
the level of 1,3-Butadiene must be below the TLV before non-emergency personnel are allowed to re-enter area. If
leaking incidentally from the cylinder or its valve, contact your supplier.
7. HANDLING and USE
WORK PRACTICES AND HYGIENE PRACTICES: Due to the potential carcinogenic effect of the 1,3Butadiene component of this product, requirements under OSHA 29 CFR 1910.1051; 29 CFR 1910.19(1) must
be followed. Be aware of any signs of dizziness or fatigue; exposures to fatal concentrations of this product could
occur without any significant warning symptoms, due to oxygen deficiency. Do not attempt to repair, adjust, or in any
other way modify the cylinders of this product. If there is a malfunction or another type of operational problem,
contact nearest distributor immediately.
STORAGE AND HANDLING PRACTICES: Cylinders should be firmly secured to prevent falling or being knockedover. Cylinders must be protected from the environment, and preferably kept at room temperature (approximately
21°C, 70°F). Cylinders should be stored in dry, well-ventilated areas, away from sources of heat, ignition, and direct
sunlight. Protect cylinders against physical damage. 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. These cylinders are
not refillable. WARNING! Do not refill DOT 39 cylinders. To do so may cause personal injury or property
damage.
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: WARNING! Compressed gases can present
significant safety hazards. During cylinder use, use equipment designed for these specific cylinders. Ensure all lines
and equipment are rated for proper service pressure.
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow practices
indicated in Section 6 (Accidental Release Measures). Make certain that application equipment is locked and
tagged-out safely. Always use product in areas where adequate ventilation is provided.
8. EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: Due to the presence of the 1,3-Butadiene component in this gas
mixture, refer to OSHA 29 CFR 1910.1051; 29 CFR 1910.19(1) for specific ventilation requirements. As with all
chemicals, use this product in well-ventilated areas. If this product is used in a poorly-ventilated area, install
automatic monitoring equipment to detect the levels of Isobutane and oxygen.
RESPIRATORY PROTECTION: No special respiratory protection is required under normal circumstances of use.
Use supplied air respiratory protection if the levels of Isobutane exceeds exposure limits presented in Section 2
(Composition and Information of Ingredients) and Oxygen levels are below 19.5%, or unknown, during emergency
response to a release of this product. If respiratory protection is needed, use only protection authorized in the U.S.
Federal OSHA Standard (29 CFR 1910.134), applicable U.S. State regulations, or the Canadian CSA Standard
Z94.4-93 and applicable standards of Canadian Provinces. Oxygen levels below 19.16.33% are considered IDLH
by OSHA. In such atmospheres, use of a full-facepiece pressure/demand SCBA or a full facepiece, supplied air
respirator with auxiliary self-contained air supply is required under OSHA’s Respiratory Protection Standard
(1910.134-1998). The following are NIOSH respiratory protection guidelines for 1,3-Butadiene:
1,3-BUTADIENE
CONCENTRATION
RESPIRATORY PROTECTION
At Concentrations Above the NIOSH REL, or Where There is no REL, at Any Detectable Concentration: Any SelfContained Breathing Apparatus (SCBA) that has a full facepiece and is operated in a
pressure-demand or other positive-pressure mode, or any Supplied-Air Respirator(SAR)
that has a full facepiece and is operated in a pressure-demand or other positive-pressure
mode in combination with an auxiliary SCBA operated in pressure-demand or other
positive-pressure mode.
Escape:
Any Air-Purifying, Full-Facepiece Respirator (gas mask) with a chin-style, front- or backmounted canister providing protection against the compound of concern, or any
appropriate escape-type, SCBA.
EYE PROTECTION: Safety glasses. If necessary, refer to U.S. OSHA 29 CFR 1910.133 or appropriate Canadian
Standards.
HAND PROTECTION: Due to the presence of 1,-3-Butadiene, it is recommended that gloves, such as Viton™,
Saranex™, Barricade™, Responder™, or Teflon™. If necessary, refer to U.S. OSHA 29 CFR 1910.138 or
appropriate Standards of Canada.
BODY PROTECTION: No special protection is needed under normal circumstances of use. If a hazard of injury to
the feet exists due to falling objects, rolling objects, where objects may pierce the soles of the feet or where
employee’s feet may be exposed to electrical hazards, use foot protection, as described in U.S. OSHA 29 CFR
1910.136.

hyperbaric chamber.
OTHER TOXICOLOGICAL DATA: Blood system effects (changes in bone marrow stem cell development,
reduction in white and red blood cells and an increase in the volume of circulating red blood cells) were observed in
several studies involving male mice exposed to 1250 ppm of the 1,3-Butadiene component of this gas mixture for 631 weeks. Effects on red blood cell enzymes, grooming activity and salivation were observed in rats exposed to
1000-8000 ppm for 13 weeks.
SUSPECTED CANCER AGENT: The components of this gas mixture are listed by agencies that track the cancer
potential of chemicals as follows:
1,3-BUTADIENE: ACGIH TLV-A2 (Suspected Human Carcinogen); EPA-B2 (Probable Human Carcinogen. Sufficient evidence from animal
studies; inadequate evidence or no data from epidemiologic studies); IARC-2A (Probably Carcinogenic to Humans); MAK-1 (Substances that
Cause Cancer in Man and Can be Assumed to Make a Significant Contribution to Cancer Risk); NIOSH-Ca (Potential Occupational
Carcinogen with No Further Categorization); NTP-K (Known to be a Human Carcinogen).
Inhalation carcinogenesis studies of 1,3-Butadiene were conducted by exposing groups of 50 male and 50 female
B6C3F1 mice 6 hours/day 5 days/week to air containing 1,3-Butadiene at concentrations of 0 (chamber controls),
625, or 1,250 ppm. These studies were planned for 103 week exposures but were terminated at weeks 60 for male
mice and weeks 61 for female mice because of the rapidly declining survival, primarily due to neoplasia. Under the
conditions of these studies, there was clear evidence of carcinogenicity for 1,3-Butadiene in male and female

mice as shown by increased incidences and early induction of hemangiosarcomas of the heart, lymphomas,
alevolar/bronchiolar adenomas and carcinomas, and papillomas of the stomach in males and females; and of acinar
cell carcinomas of the mammary gland, granulosa cell tumors of the ovary, and hepatocellular adenomas and
adenomas or carcinomas (combined) in females.
The remaining components of this gas mixture are not found on the following lists: U.S. FEDERAL OSHA Z LIST,
NTP, CAL/OSHA, and IARC; therefore are not considered to be, nor suspected to be, cancer-causing agents by
these agencies.
IRRITANCY OF PRODUCT: The 1,3-Butadiene component of this gas mixture can cause some irritation to mucus
membranes.
SENSITIZATION OF PRODUCT: No component of this gas mixture is known to be a skin or respiratory sensitizer.
REPRODUCTIVE TOXICITY INFORMATION: Listed below is information concerning the effects of this gas mixture
on the human reproductive system.
Mutagenicity: This gas mixture is not expected to cause mutagenic effects in humans. Despite their limitations,
some human studies have shown mutagenic effects in the blood cells of people occupationally exposed to the 1,3Butadiene. Animal information clearly indicates that 1,3-Butadiene is mutagenic to both somatic and germ cells.
Positive and negative results have been obtained in cultured mammalian cells, including some tests with human
cells.
Embryotoxicity: This gas mixture is not expected to cause embryotoxic effects in humans. A fetotoxic effect
(reduced body weight) has been observed in mice, in the absence of harmful effects on mothers in tests involving
the 1,3-Butadiene component of this gas mixture.
Teratogenicity: This gas mixture is not expected to cause teratogenic effects in humans. Teratogenic effects were
observed in rats in tests involving the 1,3-Butadiene component, at maternally toxic concentrations.
Reproductive Toxicity: This gas mixture is not expected to cause adverse reproductive effects in humans; however,
in animal tests 1,3-Butadiene is mutagenic to sperm which has reproductive implications.
A mutagen is a chemical which causes permanent changes to genetic material (DNA) such that the changes will propagate
through generation lines. An embryotoxin is a chemical which causes damage to a developing embryo (i.e. within the first
eight weeks of pregnancy in humans), but the damage does not propagate across generational lines. A teratogen is a
chemical which causes damage to a developing fetus, but the damage does not propagate across generational lines. A
reproductive toxin is any substance which interferes in any way with the reproductive process.
ACGIH BIOLOGICAL EXPOSURE INDICES (BEIs): Currently there are no ACGIH Biological Exposure Indices
(BEIs) applicable for this gas mixture’s components.
12. ECOLOGICAL INFORMATION
ENVIRONMENTAL STABILITY: The components of this gas mixture occur naturally in the atmosphere. The gas
will be dissipated rapidly in well-ventilated areas. The following environmental data are applicable to the
components of this product.
1,3-BUTADIENE:
Terrestrial Fate: : If spilled on land, 1,3-Butadiene will predominately volatilize very rapidly due to its very low boiling point. Dissolved in
water, it may leach through soil into groundwater due to its high water solubility and low estimated soil adsorption coefficient. It will not
appreciably hydrolyze but may be subject to biodegradation based on screening tests.
Aquatic Fate: When released into water, 1,3-Butadiene will volatilize rapidly with a half-life estimated to be 5.7 hours. It will not hydrolyze
appreciably, but may be subject to biodegradation, based on screening test.
Atmospheric Fate: Reaction with hydroxyl radicals is the dominant removal mechanism, with an estimated half life 5 hours. Reaction with ozone
and nitrate radicals may also contribute to the degradation of the chemical. Polluted urban atmospheres increase the rate of degradation
somewhat during day light hours as suggested by the detection of the highest atmospheric levels of the chemical in the early morning hours.
Acetaldehyde and acrolein have been identified as products of photo-oxidation. Rainout may contribute to removal of 1,3-Butadiene from the
atmosphere; However, evaporation from the rain may be rapid and the compound returned to the atmosphere relatively quickly unless it
leaches into the soil.
Bioconcentration: No information on the bioconcentration factor for 1,3-Butadiene could be found in the literature. However, based on its
octanol/water partition coefficient (log Kow=1.99(1)) its estimated bioconcentration factor is 9.1 and, therefore, the chemical is not expected
to appreciably bioconcentrate.

16. OTHER INFORMATION
INFORMATION ABOUT DOT-39 NRC (Non-Refillable Cylinder) PRODUCTS
DOT 39 cylinders ship as hazardous materials when full. Once the cylinders are relieved of pressure (empty)
they are not considered hazardous material or waste. Residual gas in this type of cylinder is not an issue
because toxic gas mixtures are prohibited. Calibration gas mixtures typically packaged in these cylinders are
Nonflammable n.o.s., UN 1956. A small percentage of calibration gases packaged in DOT 39 cylinders are
flammable or oxidizing gas mixtures.
For disposal of used DOT-39 cylinders, it is acceptable to place them in a landfill if local laws permit. Their
disposal is no different than that employed with other DOT containers such as spray paint cans, household
aerosols, or disposable cylinders of propane (for camping, torch etc.). When feasible, we recommended
recycling for scrap metal content. CALGAZ will do this for any customer that wishes to return cylinders to us
prepaid. All that is required is a phone call to make arrangements so we may anticipate arrival. Scrapping
cylinders involves some preparation before the metal dealer may accept them. We perform this operation as a
service to valued customers who want to participate.
MIXTURES: When two or more gases or liquefied gases are mixed, their hazardous properties may combine to
create additional, unexpected hazards. Obtain and evaluate the safety information for each component before
you produce the mixture. Consult an Industrial Hygienist or other trained person when you make your safety
evaluation of the end product. Remember, gases and liquids have properties which can cause serious injury or
death.
