3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This gas mixture is a colorless, odorless, flammable gas. A significant health hazard associated with releases of
this gas mixture is the potential for over-exposure to 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 gas mixture can cause the cylinder to burst or rupture without activating
the cylinder’s 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 gas mixture is by inhalation.
HAZARDOUS MATERIAL IDENTIFICATION SYSTEM
INHALATION: Due to the small size of an individual cylinder of this gas mixture, 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 Methane in air may be

4. FIRST-AID MEASURES
RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF OVER-EXPOSURE TO THIS GAS MIXTURE WITHOUT ADEQUATE
PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self-Contained Breathing Apparatus and Fire-Retardant Personal Protective
equipment should be worn. Adequate fire protection must be provided during rescue situations.
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 gas mixture.
RECOMMENDATIONS TO PHYSICIANS: Administer oxygen, if necessary; treat symptoms and eliminate exposure.

and equipment.
UNUSUAL FIRE AND EXPLOSION HAZARDS: When involved in a fire, Methane
(the flammable component of this gas mixture) will ignite and decompose to produce
toxic gases including carbon monoxide and carbon dioxide.
DANGER! Fires impinging (direct flame) on the outside surface of unprotected
OTHER
cylinders of this gas mixture 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 gas mixture 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 gas mixture presents significantly less risk of
flammability. 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. Uncontrolled releases should be responded to by
trained personnel using pre-planned procedures. Proper protective equipment should be used. In case of a gas release, clear the affected area,
protect people, and respond with trained personnel.
Eliminate any possible sources of ignition, and provide maximum explosion-proof ventilation. If the gas is leaking from cylinder contact the supplier.
Adequate fire protection must be provided. Use only non-sparking tools and equipment during the response.
Monitor the surrounding area (and the original area of the release) for the flammable gas concentration and the level of Oxygen. Combustible gas
concentration must be below 10% of the LEL (5% Methane) prior to entry. Additionally, Oxygen levels must be above 19.5% before nonemergency personnel are allowed to re-enter area.
If leaking incidentally from the cylinder, contact your supplier.
THIS IS AN EXTREMELY FLAMMABLE GAS. Protection of all personnel and the area must be maintained.
7. HANDLING and USE
WORK PRACTICES AND HYGIENE PRACTICES: Be aware of any signs of dizziness or fatigue; exposures to fatal concentrations of this gas
mixture could occur without any significant warning symptoms, due to 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°C [70°F]). Cylinders should be stored in dry, wellventilated 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 “No Smoking or Open Flames” 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 gas mixture in well-ventilated areas. If this gas mixture is used in a poorly-ventilated area,
install automatic monitoring equipment to detect if the level of Methane exceeds 10% of the LEL (5%), as well as the concentration of Carbon
Dioxide and Oxygen in the atmosphere.
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 gas mixture. 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).
EYE PROTECTION: Safety glasses. If necessary, refer to U.S. OSHA 29 CFR 1910.133 or appropriate Canadian Standards.
HAND PROTECTION: No special protection is needed under normal circumstances of use. 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.

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.
