3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This product is a colorless, odorless, flammable gas. A significant hazard associated with releases of this product
is the potential for over-exposure to Carbon Dioxide, a component of this gas mixture. Inhalation of Carbon Dioxide can increase respiration
and heart rate, possibly resulting in circulatory insufficiency (which may lead to coma and death). At concentrations between 2-10%, Carbon
Dioxide can cause nausea, dizziness, headache, mental confusion, increased blood pressure and respiratory rate. If the concentration of
Carbon Dioxide reaches 10% or more, suffocation can occur within minutes. Additionally, releases of this product may produce oxygen-
deficient atmospheres (especially in confined spaces or other poorly-ventilated environments); individuals in such atmospheres may be
asphyxiated. The gas poses a serious fire hazard when accidentally released. Flame or high temperature impinging on a localized area of the
cylinder of this product can cause the cylinder to burst or rupture without activating the cylinder鈥檚 relief devices. The gas may spread long
distances; distant ignition and flashback are possible. Provide adequate fire protection during emergency response situations.
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The most significant route of over-exposure for this product is by inhalation.
INHALATION: Due to the small size of an individual cylinder of this product, no unusual health effects from over-exposure to the product are
anticipated under routine circumstances of use. It should be noted that before adverse health effects or suffocation could occur, the lower
flammability limit of Butane in Nitrogen or air may be exceeded; possibly causing an explosive atmosphere as well as an oxygen-deficient
environment. A significant hazard associated with releases of this product is the potential for over-exposure to Carbon Dioxide, a component of this
gas mixture. If this product is released in a small, poorly-ventilated area (i.e. an enclosed or confined space), and if the concentration of Carbon
Dioxide reaches 10% or more, suffocation can occur within minutes. At concentrations between 2-10%, Carbon Dioxide can cause nausea,
dizziness, headache, mental confusion, increased blood pressure and respiratory rate. Carbon Dioxide initially stimulates respiration and then
causes respiratory depression. High concentrations result in narcosis. Symptoms in humans are as follows:
CONCENTRATION
OF CARBON DIOXIDE OBSERVED EFFECT
1% Slight increase in breathing rate.
2% Breathing rate increases to 50% above normal level. Prolonged exposure can cause headache, tiredness.
3% Breathing increases to twice normal rate and becomes labored. Weak narcotic effect. Impaired hearing,
headache, increase in blood pressure and pulse rate.
4-5% Breathing increases to approximately four times normal rate, symptoms of intoxication become evident and
slight choking may be felt.

such as pain, redness, and tearing. Prolonged contact of high concentrations of
Carbon Dioxide with the eyes can cause damage to the retinal ganglion cells.
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms.
For Routine Industrial Use and Handling Applications
Over-exposure to this gas mixture may cause the following health effects:
ACUTE: Due to the small size of the individual cylinder of this product, no unusual health effects from exposure to the product are anticipated
under routine circumstances of use. Due to the presence of Carbon Dioxide, inhalation of high concentrations of this gas mixture can cause
nausea, dizziness, headache, mental confusion, increased blood pressure and respiratory rate. High concentrations of Carbon Dioxide may cause
eye irritation, and potential eye damage. Another hazard associated with this gas mixture is the potential for exposure to oxygen-deficient
atmospheres. Symptoms of oxygen deficiency include respiratory difficulty, ringing in ears, headaches, shortness of breath, wheezing, headache,
dizziness, indigestion, nausea, unconsciousness, and death. The skin of a victim of over-exposure may have a blue color.
CHRONIC: Chronic exposure to oxygen-deficient atmospheres (below 18% oxygen in air) may effect the heart and nervous system.
TARGET ORGANS: ACUTE: Respiratory system, eyes. CHRONIC: Heart, cardiovascular system, central nervous system, reproductive system.
4. FIRST-AID MEASURES
RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THIS PRODUCT WITHOUT ADEQUATE
FIRE-RETARDANT AND PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self-Contained Breathing Apparatus
must be worn.
No unusual health effects are anticipated after exposure to this gas mixture, due to the small cylinder size. If any adverse symptom develops after
over-exposure to this gas mixture, remove victim(s) to fresh air as quickly as possible. Only trained personnel should administer supplemental
oxygen and/or cardio-pulmonary resuscitation if necessary. Victim(s) who experience any adverse effect after over-exposure to this gas mixture
must be taken for medical attention. Rescuers should be taken for medical attention if necessary. Take a copy of the label and the MSDS to
physician or other health professional with victim(s).
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Acute or chronic respiratory conditions may be aggravated by over-exposure to the
components of this product. Additionally, over-exposure to Carbon Dioxide (a component of this gas mixture) may aggravate eye disorders and
central nervous system conditions.
RECOMMENDATIONS TO PHYSICIANS: Administer oxygen, if necessary; treat symptoms and eliminate exposure.
5. FIRE-FIGHTING MEASURES
The following information is for Butane, the flammable component of this gas mixture.

HEALTH REACTIVITY
off the source of the gas. Use water spray to cool fire-exposed containers, structures,
and equipment.
UNUSUAL FIRE AND EXPLOSION HAZARDS: When involved in a fire, Butane (the
flammable component of this gas mixture) will ignite and decompose to produce toxic
gases including carbon monoxide and carbon dioxide.
OTHER
DANGER! Fires impinging (direct flame) on the outside surface of unprotected
cylinders of this product can be very dangerous. Exposure to fire could cause a catastrophic failure of the cylinder releasing the contents into a
fireball and explosion of released gas. The resulting fire and explosion can result in severe equipment damage and personnel injury or death over
a large area around the cylinder. For massive fires in large areas, use unmanned hose holder or monitor nozzles; if this is not possible, withdraw
from area and allow fire to burn.
Explosion Sensitivity to Mechanical Impact: Not sensitive.
Explosion Sensitivity to Static Discharge: Static discharge may cause this product to ignite explosively, if released.
SPECIAL FIRE-FIGHTING PROCEDURES: Structural fire-fighters must wear Self-Contained Breathing Apparatus and full protective equipment.
Because of the potential for a fire, evacuation of non-emergency personnel is essential. If water is not available for cooling or protection of cylinder
exposures, evacuate the area. Refer to the North American Emergency Response Guidebook (Guide #115).
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
Carbon Dioxide over-exposure, 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,
protect people, and respond with trained personnel.
Allow the gas mixture to dissipate. If necessary, monitor the surrounding area (and the original area of the release) for the flammable gas
concentration, as well as the levels of Carbon Dioxide and Oxygen. Combustible gas concentration must be below 10% of the LEL (LEL = 1.8% for
Butane in air) prior to entry. Additionally, Carbon Dioxide should not be above background levels and Oxygen levels must be above 19.5% before
non-emergency personnel are allowed to re-enter area.
If leaking incidentally from the cylinder, contact your supplier.

7. HANDLING and USE
WORK PRACTICES AND HYGIENE PRACTICES: 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 Carbon Dioxide over-exposure and oxygen deficiency. Use non-sparking tools when
working with this gas mixture. Do not attempt to repair, adjust, or in any other way modify the cylinders containing this gas mixture. 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 knocked-over. Cylinders must be
protected from the environment, and preferably kept at room temperature (approximately 21掳C [70掳F]). Cylinders should be stored in dry, well-
ventilated areas away from sources of heat, ignition and direct sunlight. Keep storage area clear of materials which can burn. Protect cylinders
against physical damage.
Cylinders 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 0.5 hours. Isolate from other incompatible chemicals (refer to Section 10,
Stability and Reactivity).
Storage areas must meet national electrical codes for Class 1 Hazardous Areas. Post 鈥淣o Smoking or Open Flames鈥? signs in storage or use
areas. Consider installation of leak detection for combustible gas levels and alarm for storage and use areas. Have appropriate extinguishing
equipment in the storage area (i.e. sprinkler system, portable fire extinguishers).
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 application equipment is locked and tagged-out safely. Purge gas handling equipment with inert gas (i.e.
nitrogen) before attempting repairs. Always use product in areas where adequate ventilation is provided.
8. EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: No special ventilation systems or engineering controls are needed under normal
circumstances of use. 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 if levels of Butane exceed 10% of the LEL in air (LEL = 1.8%), as well as the levels of Carbon Dioxide
and Oxygen.
RESPIRATORY PROTECTION: No special respiratory protection is required under normal circumstances of use. Use supplied air respiratory
protection if the level of Carbon Dioxide 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鈥檚 Respiratory Protection Standard (1910.134-1998). Respiratory selection guidelines from NIOSH for Carbon Dioxide are
provided below for information.

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.
