3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This clear, pungent-smelling, greenish gas mixture may be severely irritating. Persons who respond to releases of this gas mixture
must protect themselves from inhalation of Chlorine, the corrosive component of this gas mixture, especially in areas which are downwind of the release. Another
significant health hazard associated with this gas mixture is the potential for exposure to oxygen-deficient atmospheres, when the oxygen in the mixture is at a low
level (below 19.5%). Extreme caution must be used when responding to spills.
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), a Chlorine-enriched or oxygen-deficient environment may occur (when mixture contains less than 19.5%). Due to the presence of Chlorine,
inhalation of this gas mixture, may lead to irritation of the nose and throat. Additionally, over-exposures to Chlorine can cause the following health
effects: coughing, labored breathing, sore throat, and potentially fatal lung disorders (chemical pneumonitis and pulmonary edema). Repeated
chlorine-overexposures by inhalation can result in emphysema and erosion of teeth.

CONTACT WITH SKIN or EYES: Due to the presence of Chlorine in this gas mixture, skin over-exposures to this gas mixture may lead to burns or
dermatitis (red, cracked, irritated skin), depending upon concentration and duration of exposure. Contact of the product with the eyes can cause
pain, redness, and prolonged exposure could cause blindness.
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Over-exposure to this gas mixture may cause the health
effects described below.
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. This gas mixture may be severely irritating and may redden and damage eyes, skin, mucous membranes,
and any other exposed tissue. If this gas mixture is inhaled, irritation of the respiratory system may occur, with coughing, breathing difficulty, and the
development of lung disorders. Another significant health hazard associated with this gas mixture, when is contains less than 19.5% oxygen, 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: Persistent irritation may result from repeated exposures to this gas mixture. Repeated Chlorine-overexposures by inhalation can
result in emphysema and erosion of tooth enamel. Chronic exposure to oxygen-deficient atmospheres (below 18% oxygen in air) may affect the
heart and nervous system.
TARGET ORGANS: Acute: Respiratory system, skin, and eyes. Chronic: Skin, heart, respiratory system.
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.
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).
SKIN EXPOSURE: If irritation of the skin develops after exposure to this gas mixture, 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.
EYE EXPOSURE: If irritation of the eye develops after exposure to this 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. Seek medical assistance immediately, preferably an
ophthalmologist.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Pre-existing dermatitis and respiratory conditions may be aggravated by overexposure to this gas mixture.
RECOMMENDATIONS TO PHYSICIANS: Treat symptoms; eliminate exposure. Be observant for signs of pulmonary edema.

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
over-exposure to Chlorine, the toxic component of this gas mixture, and other safety hazards related to the remaining components of this gas
mixture, 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 levels of Chlorine and Oxygen. The level of Chlorine
must be at acceptable levels (see Section 2, Composition on Information on Ingredients) and the atmosphere must have at least 19.5 percent
oxygen before personnel can be allowed in the area without Self-Contained Breathing Apparatus.
If leaking incidentally from the cylinder, contact your supplier.
7. HANDLING and USE
WORK PRACTICES AND HYGIENE PRACTICES: All work practices should minimize the release of Chlorine. Eye wash stations/safety showers
should be near areas where this gas mixture is used or stored. All work operations should be monitored in such a way that emergency
personnel can be immediately contacted in the event of a release. 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.

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 cons idered
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 r eturn
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 whi ch can
cause serious injury or death.
