3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This is a colorless, non-flammable gas mixture with a an irritating odor.
Inhalation of this gas mixture may be irritating or corrosive (depending on level of concentration), due to the
presence of Carbonyl Difluoride. In addition, releases of this gas mixture can cause a hazard of asphyxiation
by displacement of oxygen. This gas mixture presents no hazard of flammability. If involved in a fire, this
product may decompose to produce toxic fumes of carbon monoxide, and carbon tetrafluoride. In contact
with water, the Carbonyl Difluoride component of this mixture will form highly corrosive and toxic hydrogen
Difluoride. Flame or high temperature impinging on a localized area of the cylinder can cause cylinder to
rupture violently or explosively. Extreme caution must be used when responding to releases of this gas
mixture. Persons who respond to releases of this product must protect themselves from inhalation of
Carbonyl Difluoride.
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The most significant route of over-
exposure for this product is by inhalation and skin or eye contact.
INHALATION: Inhalation of low levels of this gas mixture, may lead to irritation of the nose and throat and
respiratory system. Inhalation of higher levels of this gas mixture may result in moderate to severe irritation
or burns to the nose, throat, and lungs can occur. Symptoms can include coughing, tightness of the chest,
and difficulty breathing. Inhalation over-exposure can cause pulmonary edema (a potentially life threatening
condition), and symptoms may be delayed by hours or days. Repeated inhalation over-exposure may cause
obstructive lung disease. Severe inhalation over-exposures can lead to hypocalcemia, a life-threatening
lowering of serum calcium in the body. Inhalation of high concentrations may be fatal.
In addition, high concentrations of this gas mixture can cause an oxygen-deficient environment, especially if
released in a poorly-ventilated area (e.g., an enclosed or confined space). 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 overexposure, 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 increase, muscular coordination
slightly disturbed.
10-14% Oxygen: Emotional upset, abnormal fatigue, disturbed respiration.
6-10% Oxygen: Nausea, vomiting, collapse, or loss of consciousness.
Below 6%: Convulsive movements, possible respiratory collapse, and
death.
CONTACT WITH SKIN or EYES: Due to the presence of Carbonyl Difluoride in this gas mixture, skin over-
exposures to this product may lead to moderate to severe irritation or burns (especially in the presence of
moisture) or dermatitis (red, cracked, irritated skin), depending upon concentration and duration of
exposure. Burns may not be immediately painful or visible. Repeated skin over-exposures can result in
dermatitis (drying, cracking, and inflammation of the skin). Due to the presence of a fluoride compound
(and especially in the presence of moisture), this gas mixture can penetrate the skin, causing destruction
of the deep tissue layers, including bone tissue. This damage to the body鈥檚 tissues may continue for
days, as the fluoride ion reacts with the calcium in the skin and bone. Severe skin-contact exposures
(especially when the skin contamination exceeds 160 cm2) can lead to hypocalcemia, a life-
threatening lowering of serum calcium in the body. Contact of the product with the eyes can cause pain,
redness, and prolonged exposure could cause blindness. Contact with rapidly expanding gases (which
are released under high pressure) may cause frostbite.
SKIN ABSORPTION: The Carbonyl Difluoride component of this gas mixture presents a hazard of skin
absorption. See information, above in 鈥滳ontact with Skin or Eyes鈥? for information on skin absorption
effects.
OTHER HEALTH EFFECTS: Chronic exposure to fluoride compounds may cause deposition of fluoride in
tendons, ligaments and muscles, resulting in crippling effects. Chronic exposure may also result in
kidney damage and adverse effects on the central nervous system. Over-exposure to this product by all
routes may result in severe lowering of serum calcium in blood and tissues, which will have adverse
physiological effects, including functioning of muscles. Animal tests indicate that damage to the liver and
kidneys may occur upon repeated exposure fluoride compounds.

3. HAZARD IDENTIFICATION (Continued)
HEALTH EFFECTS OR RISKS FROM EXPOSURE: Over-exposure to this gas mixture may cause the
following health effects:
ACUTE: This gas mixture is moderately to severely irritating or corrosive (depending on concentration and
duration of exposure and the presence of moisture) and can irritate or burn and damage eyes, skin,
mucous membranes, and any other exposed tissue. If inhaled, irritation or burns to the respiratory
system may occur with coughing and difficulty breathing. Severe exposure to this product may result in
hypocalcemia, which can be fatal unless treated. Hypocalcemia is possible in all instances of inhalation
or ingestion or whenever exposure has caused large areas of burns. Severe inhalation and ingestion
over-exposure may be fatal.
CHRONIC: Persistent irritation and dermatitis (drying, cracking, and inflammation of the skin) may result
from repeated over-exposures to this product. Chronic exposure to fluoride compounds may cause
deposition of fluoride in tendons, ligaments and muscles, resulting in crippling effects. Chronic exposure
may also result in kidney damage and adverse effects on the central nervous system.
TARGET ORGANS: ACUTE: Skin, eyes, respiratory system, bones. CHRONIC: Skin, bones, ligaments,
tendons, liver, kidneys.

4. FIRST-AID MEASURES
GENERAL INFORMATION: Remove to fresh air, as quickly as possible. Only trained personnel should
administer supplemental oxygen and/or cardio-pulmonary resuscitation, if necessary. Seek medical
attention immediately.
SKIN EXPOSURE: If release of this gas mixture has resulted in frostbite, warm affected area slowly. Seek
immediate medical attention.
EYE EXPOSURE: If release of this gas mixture has affected the eyes, seek immediate medical attention.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Pre-existing acute or chronic respiratory
conditions may be aggravated by overexposure to this gas mixture.
RECOMMENDATIONS TO PHYSICIANS: Treat symptoms and eliminate overexposure. All personnel
providing treatment must be gloved. If symptoms of fluoride poisoning develop, treatment recommendations
for contamination are as follows:
Skin Contact: After 15 minute water flush (if flush has not yet been done), apply calcium gluconate gel (2.5%
concentration) until pain has subsided, but not longer than 30 minutes. If pain lasts longer than 15 minutes,
proceed with calcium gluconate injections.
Eye Contact: After 15 minutes water flush (if flush has not been done), flush eyes with 1% calcium
gluconate gel in normal, sterile saline.
Inhalation: Provide 100% oxygen, followed by inhalation of a mist containing 2.5% calcium gluconate in
saline solution. Watch for pulmonary edema.
Ingestion: Gastric lavage with lime water or milk.

5. FIRE-FIGHTING MEASURES (Continued)
SPECIAL FIRE-FIGHTING PROCEDURES: Evacuate all personnel from danger area. Immediately cool
cylinders with water spray from maximum distance, to avoid danger of cylinder rupture. Incipient fire
responders should wear eye protection. Structural fire fighters must wear Self-Contained Breathing
Apparatus and full protective equipment. When cool, move cylinders from fire area if this can be done
without risk to firefighters. Other information for pre-planning can be found in the North American
Emergency Response Guidebook (Guide Number 126).
6. ACCIDENTAL RELEASE MEASURES
LEAK RESPONSE: Evacuate immediate area. Uncontrolled releases should be responded to by trained
personnel using pre-planned procedures. Proper protective equipment, should be used in the event of a
significant release from a single cylinder. Use only non-sparking tools. Call CHEMTREC (1-800-424-9300)
for emergency assistance. Or if in Canada, call CANUTEC (613-996-6666).
Attempt to close the main source valve prior to entering the area. If this does not stop the release (or if it is
not possible to reach the valve), allow the gas to release in-place or remove it to a safe area and allow the
gas to be released there. Protect personnel attempting to shut-off with water spray. Monitor the surrounding
area for the level of Carbonyl Difluoride and Oxygen. The atmosphere must have at least 19.5 percent
Oxygen before non-emergency personnel can be allowed in the area without Self-Contained Breathing
Apparatus.
7. HANDLING and USE
WORK PRACTICES AND HYGIENE PRACTICES
ALL AREAS WHERE THIS GAS MIXTURE IS USED SHOULD CONTAIN INSTANT ACTING SHOWERS
IN EVENT OF CONTAMINATION. Calcium gluconate gel should be readily accessible in areas
where potential exposure to this gas mixture exists.
Do not eat or drink while handling chemicals.
Be aware of all potential exposure symptoms; exposures to a fatal oxygen-deficient atmosphere could occur
without any significant warning symptoms.
All work operations should be monitored in such a way that emergency personnel can be immediately
contacted in the event of a release.
Workers who handle this gas mixture should wear protective clothing, as listed in Section 8 (Exposure
Controls and Personal Protection).
If ventilation controls are not adequate to provide sufficient oxygen content, proper respiratory protection
equipment should be provided and workers using such equipment should be carefully trained in its
operation and limitations.
Precautions must always be taken to prevent suck-back of foreign materials into the cylinder by using a
check-valve, or vacuum break, since suck-back may cause dangerous pressure changes within the
cylinder.
STORAGE AND HANDLING PRACTICES:
Cylinders should be stored upright and be firmly secured to prevent falling or being knocked-over. Cylinders
can be stored in the open, but in such cases, should be protected against extremes of weather and from
the dampness of the ground to prevent rusting. Cylinders should be stored in dry, well-ventilated areas
away from sources of heat or ignition. Do not allow the area where cylinders are stored to exceed 52掳C
(125掳F).
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: Compressed gases can present significant
safety hazards. The following rules are applicable to work situations in which cylinders are being used.
Before Use: Move cylinders with a suitable hand-truck. Do not drag, slide or roll cylinders. Do not drop
cylinders or permit them to strike each other. Secure cylinders firmly. Leave the valve protection cap
(where provided) in-place until cylinder is ready for use.

7. HANDLING and USE (Continued)
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS (continued):
During Use: Use designated CGA fittings and other support equipment. Do not use adapters. Do not use
oils or grease on gas-handling fittings or equipment. Immediately contact the supplier if there are any
difficulties associated with operating the cylinder valve. Never insert an object (e.g wrench, screwdriver,
pry bar, etc.) into valve cap openings. Doing so may damage the valve, causing a leak to occur. Use an
adjustable strap wrench to remove over-tight or rusted caps. Never strike an arc, on a compressed gas
cylinder or make a cylinder part of and electric circuit.
After Use: Close main cylinder valve. Replace valve protection cap. Close valve after each use and when
empty. Mark empty cylinders 鈥淓MPTY鈥?.
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Refer to current
CGA Guidelines for information on protective practices during maintenance of contaminated equipment.
8. EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: Use with adequate, ventilation to ensure compliance with
exposure limits described in Section 2 (Composition and Information on Ingredients). Local exhaust
ventilation is preferred, because it prevents dispersion of this gas mixture into the work place by eliminating it
at its source. If appropriate, install automatic monitoring equipment to detect the level of Oxygen and
Carbonyl Difluoride.
RESPIRATORY PROTECTION: Maintain the Oxygen level above 19.5% in the workplace. If necessary, use
only respiratory protection authorized in the U.S. Federal OSHA Respiratory Protection Standard (29 CFR
1910.134), or equivalent U.S. State standards and 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). The following are NIOSH respiratory protection
guidelines for Hydrogen Fluoride, a possible decomposition product by hydrolysis this gas mixture. These
are presented as this component presents a risk of toxicity in this mixture.
HYDROGEN FLUORIDE
CONCENTRATION RESPIRATORY EQUIPMENT
Up to 30 ppm Chemical cartridge respirator or powered air-purifying respirator with cartridges,
or gas mask with canister or a Supplied Air Respirator (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.
Escape Gas mask or mouth-piece respirator with Hydrogen Fluoride cartridges or
escape-type SCBA should be used.
EYE PROTECTION: Splash goggles or safety glasses, with a faceshield. If necessary, refer to U.S. OSHA 29
CFR 1910.133, or appropriate Canadian Standards.
HAND PROTECTION: Wear mechanically-resistant gloves when handling cylinders containing this gas
mixture. If necessary, refer to U.S. OSHA 29 CFR 1910.138, or appropriate Standards of Canada.
BODY PROTECTION: Use body protection appropriate for task. An apron or other impermeable body
protection is suggested. Full-body chemical protective clothing is recommended for emergency response
procedures. Transfer of large quantities under pressure may require protective equipment appropriate to the
task. 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, foot protection should
be used, as described in U.S. OSHA 29 CFR 1910.136.
