3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This is a colorless, odorless gas mixture. Releases of this
gas mixture may produce oxygen-deficient atmospheres (especially in confined spaces or
other poorly-ventilated environments); individuals in such atmospheres may be asphyxiated.
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The most significant
route of over-exposure for this gas mixture is by inhalation.
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. If this gas mixture is released in a small, poorly-ventilated area (i.e.
an enclosed or confined space), an oxygen-deficient environment may occur. Individuals
breathing such an atmosphere may experience symptoms which include headaches,
ringing in ears, dizziness, drowsiness, unconsciousness, nausea, vomiting, and
depression of all the senses. Under some circumstances of over-exposure, death may
occur. The effects associated with various levels of oxygen are as follows:
CONCENTRATION OF OXYGEN
OBSERVED EFFECT
12-16% Oxygen:
Breathing and pulse rate increased, muscular
coordination slightly disturbed.
10-14% Oxygen:
Emotional upset, abnormal fatigue, disturbed
respiration.
6-10% Oxygen:
Na us e a, vom iti ng, c ol l aps e, or l oss of
consciousness.

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 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 preplanned 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 Oxygen. 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 gas
mixture 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 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. 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: 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 the levels of Methane and Oxygen.
RESPIRATORY PROTECTION: No special respiratory protection is required under normal circumstances of use. Maintain Methane levels below
50% of the TLV (TLV = 1000 ppm) and oxygen levels above 19.5% in the workplace. Use supplied air respiratory protection when Methane levels
exceed 50% of the TLV (TLV = 1000 ppm), oxygen levels are below 19.5%, or during emergency response to a release of this gas mixture.
During an emergency situation, before entering the area, check the concentration of Methane and Oxygen. 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 19.5% 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: Wear leather gloves when handling cylinders. Chemically resistant gloves should be worn when using this gas mixture. 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. CAL GAZ 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 propert ies which can
cause serious injury or death.
