3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: Deuterium is a colorless, odorless gas which is a stable isotope of hydrogen.
Deuterium poses a serious fire hazard when it is accidentally released. The main health hazard associated with
releases of this gas is asphyxiation by displacement of oxygen. Rapidly expanding gases can cause frostbite to any
contaminated tissue. Provide adequate fire protection during emergency response situations.
SYMPTOMS OF OVEREXPOSURE BY ROUTE OF EXPOSURE:
The most significant route of overexposure for this gas is by inhalation. HAZARDOUS MATERIAL INFORMATION

See Section 16 for Definition of Ratings
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in
Lay Terms. Overexposure to Deuterium may cause the following
health effects:
ACUTE: The most significant hazard associated with this gas is inhalation of oxygen-deficient atmospheres. Symptoms of
oxygen deficiency include respiratory difficulty, ringing in ears, headaches, dizziness, indigestion, nausea, and death. The
skin of a victim of overexposure may have a blue color. Contact with rapidly expanding gases may cause frostbite.
CHRONIC: There are currently no known adverse health effects associated with chronic exposure to this gas.
TARGET ORGANS: Respiratory system.
PART II What should I do if a hazardous situation occurs?
4. FIRST-AID MEASURES
RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO DEUTERIUM
WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self-Contained
Breathing Apparatus and Fire-Retardant Personal Protective equipment should be worn. Adequate
fire protection must be provided during rescue situations.
Remove victim(s) to fresh air, as quickly as possible. Trained personnel should administer supplemental oxygen and/or
cardio-pulmonary resuscitation, if necessary. Only trained personnel should administer supplemental oxygen.
In case of frostbite, place the frostbitten part in warm water. DO NOT USE HOT WATER. If warm water is not available, or
is impractical to use, wrap the affected parts gently in blankets. Alternatively, if the fingers or hands are frostbitten, place the
affected area in the armpit. Encourage victim to gently exercise the affected part while being warmed. Seek immediate
medical attention.
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).

invisible blue flame.
of Ratings
Explosion Sensitivity to Mechanical Impact: Not sensitive.
Explosion Sensitivity to Static Discharge: Static discharge may cause this gas to ignite. Due to low electrical conductivity,
this substance can generate electrostatic charges during handling operations.
SPECIAL FIRE-FIGHTING PROCEDURES: Structural firefighters must wear Self-Contained Breathing Apparatus and full
protective equipment. The best fire-fighting technique may be simply to let the burning gas escape from the pipeline or
other container. Stop the leak before extinguishing fire. If the fire is extinguished before the leak is sealed, the leaking gas
could re-ignite without warning and cause extensive damage, injury, or fatality. In this case, increase ventilation to prevent
flammable mixture formation. For large releases, consider evacuation. Refer to the North American Emergency Response
Guidebook (Guide #115) for additional information.
6. ACCIDENTAL RELEASE MEASURES
SPILL AND LEAK RESPONSE: Uncontrolled releases should be responded to by trained personnel using pre-planned
procedures. Proper protective equipment should be used. In case of a release, clear the affected area, protect people, and
respond with trained personnel. Adequate fire protection must be provided. Minimum Personal Protective Equipment
should be Level B: fire-retardant protective clothing, mechanically-resistant gloves and Self-Contained Breathing
Apparatus. Use only non-sparking tools and equipment. Locate and seal the source of the leaking gas. Protect
personnel attempting the shut-off with water-spray. Allow the gas, which is lighter than air, to dissipate. Monitor the
surrounding area for combustible gas and oxygen levels. Combustible gas concentration must be below 10% of the LEL
(LEL = 4.9%) prior to entry. The atmosphere must have at least 19.5 percent oxygen before personnel can be allowed in
the area without Self-Contained Breathing Apparatus. 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.
THIS IS AN EXTREMELY FLAMMABLE GAS. Protection of all personnel and the area must be maintained.
PART III How can I prevent hazardous situations from occurring?
7. HANDLING and STORAGE
WORK PRACTICES AND HYGIENE PRACTICES: As with all chemicals, avoid getting Deuterium IN YOU. Do not eat or
drink while handling chemicals. Be aware of any signs of dizziness or fatigue; exposures to fatal concentrations of
Deuterium could occur without any significant warning symptoms.
STORAGE AND HANDLING PRACTICES: Cylinders should be stored in dry, well-ventilated areas away from sources of
heat. Compressed gases can present significant safety hazards. Store containers away from heavily trafficked areas and
emergency exits. Post 鈥淣o Smoking or Open Flames鈥? signs in storage or use areas.
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: Protect cylinders against physical damage. Store in cool,
dry, well-ventilated area, away from sources of heat, ignition and direct sunlight. Do not allow area where cylinders are
stored to exceed 52 掳C (125掳F). Isolate from oxidizers such as oxygen, chlorine, or fluorine. Use a check valve or trap in
the discharge line to prevent hazardous backflow. Post 鈥淣o Smoking or Open Flame鈥? signs in storage and use areas.
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. Never tamper with pressure relief devices in valves and cylinders. Electrical equipment should be non-
sparking or explosion proof. The following rules are applicable to situations in which cylinders are being used:
DEUTERIUM - D2 MSDS (Document # 001017) PAGE 3 OF 7
7. HANDLING and STORAGE (Continued)
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 in-place (where provided) until cylinder
is ready for use.
During Use: Use designated CGA fittings and other support equipment. Do not use adapters. Do not heat cylinder by
any means to increase the discharge rate of the product from the cylinder. Use check valve or trap in discharge line to
prevent hazardous backflow into the cylinder. Do not use oils or grease on gas-handling fittings or equipment.
After Use: Close main cylinder valve. Replace valve protection cap (where provided). Mark empty cylinders 鈥淓MPTY鈥?.
NOTE: Use only DOT or ASME code containers. Earth-ground and bond all lines and equipment associated with
Deuterium. Close valve after each use and when empty. Cylinders must not be recharged except by or with the consent of
owner. For additional information refer to the Compressed Gas Association Pamphlet P-1, Safe Handling of Compressed
Gases in Containers and G-5: 鈥淗ydrogen鈥?. Additionally, refer to CGA Bulletin SB-2 鈥淥xygen Deficient Atmospheres鈥?.
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 (e.g. nitrogen) before attempting repairs.
8. EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: Use with adequate ventilation. Local exhaust ventilation is preferred,
because it prevents Deuterium dispersion into the work place by eliminating it at its source. If appropriate, install automatic
monitoring equipment to detect the presence of potentially flammable air-gas mixtures and the level of oxygen. Monitoring
devices should be installed near the ceiling.
RESPIRATORY PROTECTION: Maintain oxygen levels above 19.5% in the workplace. Use supplied air respiratory
protection during emergency response to a release of Deuterium or if oxygen levels are below 19.5%. If respiratory
protection is required, follow the requirements of the Federal OSHA Respiratory Protection Standard (29 CFR 1910.134), or
equivalent State standards.
EYE PROTECTION: Splash goggles or safety glasses, for protection from rapidly expanding gases.
HAND PROTECTION: Wear mechanical resistant gloves when handling cylinders of Deuterium.
BODY PROTECTION: Use body protection appropriate for task.

11. TOXICOLOGICAL INFORMATION
TOXICITY DATA: There is no specific toxicology data for Deuterium. Deuterium is a simple asphyxiant, which acts to
displace oxygen in the environment.
SUSPECTED CANCER AGENT: Deuterium is not found on the following lists: FEDERAL OSHA Z LIST, NTP, CAL/OSHA,
IARC and there fore is not considered to be, nor suspected to be a cancer-causing agent by these agencies.
IRRITANCY OF PRODUCT: Contact with rapidly expanding gases can be irritating to exposed skin and eyes.
SENSITIZATION OF PRODUCT: Deuterium is not known to be a sensitizer upon repeated or prolonged exposure.
REPRODUCTIVE TOXICITY INFORMATION: Listed below is information concerning the effects of Deuterium on the
human reproductive system.
Mutagenicity: Deuterium is not expected to cause mutagenic effects in humans.
Teratogenicity: Deuterium is not expected to cause teratogenic effects in humans.
Embryotoxicity: Deuterium has not been reported to cause embryotoxic effects
Reproductive Toxicity: Deuterium is not expected to cause adverse reproductive effects in humans.
A mutagen is a chemical which causes permanent changes to genetic material (DNA) such that the changes will propagate
through generation lines. An embryotoxin is a chemical which causes damage to a developing embryo (i.e. within the first
eight weeks of pregnancy in humans), but the damage does not propagate across generational lines. A teratogen is a
chemical which causes damage to a developing fetus, but the damage does not propagate across generational lines. A
reproductive toxin is any substance which interferes in any way with the reproductive process.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Pre-existing respiratory conditions may be aggravated by
overexposure to Deuterium.
RECOMMENDATIONS TO PHYSICIANS: Treat symptoms and reduce overexposure.
BIOLOGICAL EXPOSURE INDICES (BEIs): Currently, Biological Exposure Indices (BEIs) are not applicable for
Deuterium.
12. ECOLOGICAL INFORMATION
ENVIRONMENTAL STABILITY: The gas will be dissipated rapidly in well-ventilated areas.
EFFECT OF MATERIAL ON PLANTS or ANIMALS: Any adverse effect on animals would be related to oxygen-deficient
environments. Deuterium stunts the growth of mammals when drunk regularly as heavy water. No adverse effect is
anticipated to occur to plant life, except for frost produced in the presence of rapidly expanding gases.
EFFECT OF CHEMICAL ON AQUATIC LIFE: No evidence is currently available on the effects of Deuterium on aquatic
life.
