3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This gas mixture is a colorless, to red-brown, oxidizing gas which is either odorless or has an acrid odor. The Nitrogen Dioxide
component of this gas mixture is extremely toxic by inhalation, and symptoms of over-exposure may not become apparent for up to 72 hours. Over-exposures to
this gas mixture may result in severe irritation and burns of eyes, skin, mucous membranes, and any other exposed tissue. If high concentrations of Nitrogen
Dioxide (> 100 ppm) are inhaled, delayed pulmonary damage and breathing difficulty may occur. Additionally, 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), there is a potential for inhalation over-exposures to Nitrogen Dioxide. Such over-exposure can result in serious health consequences,
especially if the Nitrogen Dioxide concentration is over 100 ppm. Unless otherwise noted, the information presented for symptoms which can
develop after over-exposure to specific concentrations of Nitrogen Dioxide are in ranges which exist in this gas mixture. Exposure to Nitrogen
Dioxide gas in low concentrations produces an irritating effect on the mucous membranes of the eyes, nose, throat, and lungs. Acute exposure
through inhalation may result in dryness and irritation of the nose and throat, choking, coughing, and bronchospasm. Severe over-exposure may
cause death through systemic, delayed pulmonary edema. Exposure to high concentrations may cause unconsciousness, and under some
circumstances, death.
INHALATION (continued): Typical symptoms of over-exposure to Nitrogen Dioxide are as follows:
NITROGEN DIOXIDE
CONCENTRATION OBSERVED EFFECT
25 ppm for 8 hours Delayed (5 - 72 hours) pulmonary irritation
100 - 150 ppm Delayed (5-48 hours) pulmonary edema and for 30 - 60 minutes symptoms of pulmonary dysfunction.
200 - 700 ppm Severe pulmonary damage may result after a delay any exposure of 5-8 hours.
NOTE: This gas mixture contains a maximum of 220 ppm Nitrogen Dioxide. Data pertinent to higher concentrations of
Nitrogen Dioxide are provided to give complete information on effects observed in humans after over-exposures
have occurred.
Additionally, if mixtures of this gas mixture contain less than 19.5% Oxygen and are 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 listed on the following page.

HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. F o r R o u tin e In d u s tria l U s e a n d H a n d lin g A p p lic a tio n s
Over-exposure to this gas mixture may cause the following health effects:
ACUTE: Due to the small size of the individual cylinder of this gas mixture, no unusual health effects from exposure to the product are anticipated
under routine circumstances of use. Due to the presence of Nitrogen Dioxide, this gas mixture is potentially damaging to the respiratory system.
Over-exposures may result in severe irritation and burns of eyes, skin, mucous membranes, and any other exposed tissue. If high concentrations
of Nitrogen Dioxide (> 100 ppm) are inhaled, delayed pulmonary damage and breathing difficulty may occur. Contact with rapidly expanding gases
(which are released under high pressure) may cause frostbite. Symptoms of frostbite include change in skin color to white or grayish-yellow. The
pain after contact with liquid can quickly subside.
CHRONIC: Due to the presence of Nitrogen Dioxide, prolonged or repeated over-exposures this gas mixture may cause respiratory problems,
bronchitis, hacking cough, nasal irritation and discharge, increased fatigue, alteration in the senses of taste and smell. Repeated over exposures to
Nitrogen Dioxide can also result in dental erosion and gum disorders.
TARGET ORGANS: ACUTE: Respiratory system, central nervous system, skin, eyes. CHRONIC: Skin, respiratory system, heart, teeth.
4. FIRST-AID MEASURES
RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THIS GAS MIXTURE
WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self-Contained Breathing
Apparatus must be worn. Victim(s) must be taken for medical attention. Rescuers should be taken for medical attention, if necessary.
Take copy of label and MSDS to physician or other health professional with victim(s).
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.
n the event of severe over-exposures in which the victim is unconscious, vomiting may occur as the person awakes. In order to prevent aspiration,
exposed individuals should be placed on their side with their head at the level or slightly lower than their body. Due the possibility of the victim
developing pulmonary edema, the symptoms of which can be delayed up to 72 hours, the victim should be discouraged from physical exertion
during this time period.
SKIN EXPOSURE: If this gas mixture contaminates the skin, immediately begin decontamination with running water. Minimum flushing is for 15
minutes. Remove exposed or contaminated clothing, taking care not to contaminate eyes. Victim must seek immediate medical attention.
NOTICE! In the event of severe over-exposures, delayed onset of life-threatening symptoms may occur. Victim(s) must be taken for
medical attention. Rescuers should be taken for medical attention, if necessary. Take copy of label and MSDS to physician or other health
professional with victim(s). Medical care providers should refer to Section 11 (Toxicological Information) of this MSDS for additional information.
EYE EXPOSURE: If irritation of the eye develops after exposure to the gas mixture, open victim's eyes while under gentle running water. Use
sufficient force to open eyelids. Have victim "roll" eyes. Minimum flushing is for 15 minutes.

Explosion Sensitivity to Mechanical Impact: Not sensitive.
Explosion Sensitivity to Static Discharge: Not sensitive.
SPECIAL FIRE-FIGHTING PROCEDURES: Structural firefighters must wear Self-Contained Breathing Apparatus and full protective equipment.
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
associated with Nitrogen Dioxide over-exposure, an oxygen-deficient environment, or 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 leak, clear
the affected area, protect people, and respond with trained personnel. Adequate fire protection must be provided. Allow the gas mixture to
dissipate. If necessary, monitor the surrounding area (and the original area of the release) for Nitrogen Dioxide and Oxygen. The level of Nitrogen
Dioxide must be below levels indicated in Section 2 (Composition and Information on Ingredients) 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
STORAGE AND HANDLING PRACTICES: Be aware of any signs of dizziness or breathing difficulty, especially if work is done in poorly ventilated
areas; exposures to fatal concentrations of this gas mixture could occur without any significant warning symptoms, due to Nitrogen Dioxide over-
exposure or an oxygen-deficient environment. Eye wash stations/safety showers should be near areas where this gas mixture is used or stored.
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. Protect cylinders against physical damage. Store containers away from heavily trafficked areas and emergency exits. Store away
from process and production areas, away from elevators, building and room exits or main aisles leading to exits. Consider installation of leak
NON-FLAMMABLE GAS MIXTURE MSDS EFFECTIVE DATE: APRIL 26, 2005

7. HANDLING and USE (continued)
detection 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. Employee exposure should be monitored and reduced
to the lowest practical levels using ventilation or other, appropriate, engineering controls.
RESPIRATORY PROTECTION: No special respiratory protection is required under normal circumstances of use. Use supplied air respiratory
protection if the level of Nitrogen 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. 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鈥檚 Respiratory Protection Standard (1910.134-
1998). Respiratory selection guidelines from NIOSH for Nitrogen Dioxide are provided below for information.
NIOSH/OSHA RECOMMENDATIONS FOR NITROGEN DIOXIDE CONCENTRATIONS IN AIR:
Up to 20 ppm Supplied Air Respirator (SAR) operated in a continuous-flow mode; or full-facepiece Self-Contained Breathing
Apparatus (SCBA); or full-facepiece SAR.
Emergency or Planned Entry into Unknown Concentration or IDLH Conditions: Positive pressure, full-facepiece SCBA; or positive pressure, full-
facepiece SAR with an auxiliary positive pressure SCBA.
The IDLH concentration for Nitrogen Dioxide is 20 ppm.
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鈥檚 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, 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.
