Hazard Identification
EMERGENCY OVERVIEW: This product is a colorless, odorless gas. Releases of this product for which Nitrogen is
the balance gas may produce oxygen璬eficient atmospheres (especially in confined spaces or other poorly-ventilated
environments); individuals in such atmospheres may be asphyxiated. Components of this product (1,1,2-Trichloro-
1,1,2-trichluoroethane, Tetrafluoromethane, Trichlorofluoromethane, and Dichlorodifluoromethane) may cause
drowsiness and other central nervous system effects in high concentrations; however, due to their low concentration in
this gas mixture, this is unlikely to occur. If components of this are exposed to fire, they may decompose yielding toxic
products (i.e. hydrogen fluoride, phosgene, hydrogen chloride, carbonyl fluoride).

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. The chief health hazard associated with this
gas mixture for which Nitrogen is the balance gas and is released in a small, poorly-ventilated area (i.e. an enclosed or
confined space) is the development of an oxygen-deficient environment. Individuals breathing such an atmosphere
may experience symptoms which include headache, ringing in ears, dizziness, drowsiness, unconsciousness, nausea,
vomiting, and depression of all the senses. Under some circumstances of over-exposure, death may occur. The effect
associated with various levels of oxygen are as follows.
Health Effects or Risks From Exposure: Over-exposure to this gas mixture may cause the following health effects:
v 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. The most significant hazard associated with this
gas mixture when it contains less than 19.5% oxygen is the potential for exposure to oxygen-deficient
atmospheres. Symptoms of oxygen deficient include respiratory difficulty, ringing in ears, headache, shortness of
breathing, wheezing, headaches, dizziness, indigestion, nausea, unconsciousness, and death. The skin of a victim
of over-exposure may have a blue color.
v Chronic: There are currently no known adverse health effects associated with chronic exposure to this gas.
v Target Organs: Respiratory system
First Aid Measures
Rescuers should not attempt to retrieve victims of exposure to this product without adequate personal protective
equipment. If necessary, Self - Contained Breathing Apparatus must be worn. No unusual health effects are
anticipated after exposure to this product, due to the small cylinder size. If any adverse symptom develops after over-
exposure to this product, 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 product 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).

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 ?deficiency environment and other safety hazards that 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 immediately area. Such release 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 oxygen. Oxygen levels must be above 19.5% before non ?emergency personnel are
allowed to re ?enter area. If leaking comes from the cylinder, contact your supplier.

Handling and Storage
Be aware of any signs of dizziness or fatigue, especially if work is done in poorly ?ventilated area; exposures
to fatal concentrations of this product could occur without any significant warning symptom, due to oxygen deficiency.
Do not attempt to repair, adjust, or in any other way modify cylinders contained with this gas mixture. If there is a
malfunction or another type of operational problem, contact nearest distributor immediately. 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篊; 70篎). Cylinders should be stored in dry, well ?ventilated
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. Compressed gases can present
significant safety hazards. During cylinder use, use equipment designed for these specific cylinders. Ensure all lines
and equipment is rated for proper service pressure.

Other Information
Information About CT 39 (DOT-39) NRC (Non-Refillable Cylinders) Products
CT 39 (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 packed in these cylinders are Nonflammable n.o.s., UN
1956. A small percentage of calibration gases packed in CT 39 (DOT 39) cylinders are flammable or oxidizing gas
mixtures.
For disposal of used CT 39 (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 CT (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. Precision Gas Products Inc. 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 to
valued customers who want to participate.
