gas mixture, which is under pressure, is subject to heat or flames.
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The most significant route of over-exposure for
this gas mixture is by inhalation.
INHALATION: This gas mixture is non-toxic and has the oxygen content necessary to support life.
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Over-exposure to this gas
mixture may cause the following health effects.
ACUTE: The most significant hazard associated with gas mixture is the pressure hazard.

4 FIRST-AID MEASURES
The opportunity for injury from this gas mixture is limited to over-pressure accidents, which can occur after the rapid
release of the gas from the cylinder. In the event of such accidents, seek immediate and qualified medical attention.
5. FIRE-FIGHTING MEASURES
FLASH POINT: Not applicable.
AUTOIGNITION TEMPERATURE: Not applicable.
FLAMMABLE LIMITS (in air by volume, %):
Lower (LEL): Not applicable.
Upper (UEL): Not applicable.
FIRE EXTINGUISHING MATERIALS: Non-flammable. Use extinguishing media appropriate for surrounding fire.
UNUSUAL FIRE AND EXPLOSION HAZARDS: This gas mixture will not burn; however, it will support combustion
of flammable materials. Cylinders, when involved in a fire, may rupture or burst in the heat of the fire.
Explosion Sensitivity to Mechanical Impact: Not sensitive.
Explosion Sensitivity to Static Discharge: Not sensitive.
SPECIAL FIRE-FIGHTING PROCEDURES: Incipient fire responders should wear eye protection. Structural fire-
fighters must wear Self-Contained Breathing Apparatus and full protective equipment. If possible, shut off the flow of
this gas mixture supporting the fire. Immediately cool the cylinders with water spray from a maximum distance.
When cool, move cylinders from fire area if this can be done without risk to firefighters.
6. ACCIDENTAL RELEASE MEASURES
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. Minimum Personal Protective Equipment should be Level D: safety
glasses. Locate and seal the source of the leaking gas. 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.
If leaking incidentally from the cylinder or its valve, contact your supplier.
7. HANDLING AND STORAGE
WORK PRACTICES AND HYGIENE PRACTICES: Though this gas mixture contains sufficient oxygen to sustain
life, it must be treated as unfit for human consumption and should not be used in applications requiring breathing air.
STORAGE AND HANDLING PRACTICES: Compressed gases can present significant safety hazards. Store
cylinders away from heavily trafficked areas and emergency exits. Cylinders should be stored upright (with valve
protection cap in place) and 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, ignition, and
direct sunlight. Keep storage area clear of materials that can burn.
Do not allow area where cylinders are stored to exceed 52掳C (125掳F). Store containers away from heavily trafficked
areas and emergency exits. Store away from process and gas production areas, elevators, building and room exits,
or main aisles leading to exits. Protect cylinders against physical damage.
Keep the smallest amount on-site as is necessary. 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. Use a check valve in
the discharge line to prevent hazardous backflow. Never tamper with pressure relief devices in valves and cylinders.
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.
During Use: Use designated CGA fittings and other support equipment. Do not use adapters. Use piping and
equipment adequately designed to withstand pressures to be encountered. Do not heat cylinder by any means to
increase the discharge rate of the gas mixture from the cylinder. Do not use oils or grease on gas-handling fittings or
equipment. Leak check system with leak detection solution, never with flame. Immediately contact the supplier if
there are any difficulties associated with operating cylinder valve. Never insert an object (e.g., wrench, screwdriver,
pry bar, etc.) into valve cap openings. Doing so may damage valve, casing a leak to occur. Use an adjustable strap

wrench to remove overly tight or rusted caps. Never strike an arc on a compressed gas cylinder or make a cylinder
part of an electric circuit.
7. HANDLING AND STORAGE (Continued)
After Use: Close main cylinder valve. Valves should be closed tightly. Replace valve protection cap. Mark empty
cylinders 鈥淓MPTY鈥?.
NOTE: Use only DOT or ASME code cylinders designed for compressed gas storage. Close valve after each use
and when empty. Cylinders must not be recharged except by or with the consent of owner.
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 before attempting repairs. Always use this gas mixture in areas
where adequate ventilation is provided.
