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 Isobutane. Isobutane levels must be below exposure level listed in Section 2
(Composition and Information on Ingredients) before non-emergency personnel are allowed to re-enter area.
If leaking incidentally from the cylinder or its valve, contact your supplier.

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, LLC 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.
