THRESHOLD LIMIT VALUE: TLV-TWA Data from 2007 Guide to Occupational Exposure Values (ACGIH).
TLV-TWAs should be used as a guide in the control of health hazards and not as fine lines between safe and
dangerous concentrations.
EFFECTS OF A SINGLE (ACUTE) OVEREXPOSURE:
Asphyxiant. Moderate concentrations may cause headache, drowsiness, dizziness, stinging
INHALATION:
of the nose and throat, excitation, rapid breathing, excess salivation, vomiting and
unconsciousness. This product contains traces of Nitrous Oxide which may cause
incoordination and narcosis, and clinical anaesthesia. Lack of oxygen can kill.
SKIN CONTACT: No evidence of adverse effects from available information.
No evidence of adverse effects from available information.
SKIN
ABSORPTION:
A highly unlikely route of exposure. This product is a gas at room temperature and pressure.
SWALLOWING:
No evidence of adverse effects from available information.
EYE CONTACT:
EFFECTS OF REPEATED (CHRONIC) OVEREXPOSURE:
Metabolic injury to the nervous system has resulted from frequent exposure to anaesthetic concentrations of Nitrous
Oxide.
OTHER EFFECTS OF OVEREXPOSURE:
This product is an asphyxiant. Exposure to Nitrous Oxide has produced embryo fetal toxicity in laboratory animals.
Exposure to Nitrous Oxide may be associated with an increased incidence of abortion in humans.
MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE:
A knowledge of the available toxicology information and of the physical and chemical properties of the material
suggests that overexposure is unlikely to aggravate existing medical conditions.
SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH HAZARD EVALUATION:
None currently known.
CARCINOGENICITY:
Classified A4 (Not classifiable for human or animal.) by ACGIH [Nitrous oxide].
4. First Aid Measures
INHALATION:
Remove to fresh air. If not breathing, give artifical respiration. If breathing is difficult, qualified personnel may give
oxygen. Call a physician.
SKIN CONTACT:
Wash with soap and water.
SWALLOWING:
This product is a gas at normal temperature and pressure.
EYE CONTACT:
Flush with water.
NOTES TO PHYSICIAN:
There is no specific antidote. Treatment of over-exposure should be directed at the control of symptoms and the clinical
condition.

EXTINGUISHING MEDIA:
This mixture cannot catch fire. Use media appropriate for surrounding fire.
SPECIAL FIRE FIGHTING PROCEDURES:
CAUTION! Evacuate all personnel from danger area. Immediately deluge cylinders with water from maximum distance
until cool; then move them away from fire area if without risk.
UNUSUAL FIRE AND EXPLOSION HAZARD:
Gas mixture (high pressure gas) cannot catch fire. Container may rutpure due to heat of fire. No part of a container
should be subjected to a temperature higher than 52 C. Most containers are provided with a pressure relief device
designed to vent contents when they are exposed to elevated temperature.
HAZARDOUS COMBUSTION PRODUCTS:
Not applicable.
SENSITIVITY TO IMPACT:
Avoid impact against container.
SENSITIVITY TO STATIC DISCHARGE:
Not available.
6. Accidental Release Measures
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED:
High-pressure gas. Evacuate all personnel from danger area. Use self-contained breathing apparatus
CAUTION!
where needed. Shut off flow if you can do so without risk. Ventilate area or move cylinder to a
well-ventilated area. Test for sufficient oxygen, especially in confined spaces, before allowing reentry of
personnel.
WASTE DISPOSAL METHOD:
Prevent waste from contaminating the surrounding environment. Keep personnel away. Discard any product, residue,
disposable container, or liner in an environmentally acceptable manner, in full compliance with federal, provoncial, and
local regulations. If necessary, call your local supplier for assistance.
7. Handling and Storage
PRECAUTIONS TO BE TAKEN IN STORAGE:
Store and use with adequate ventilation. Firmly secure cylinders upright to keep them from falling or being knocked
over. Screw valve protection cap firmly in place by hand. Store only where temperature will not exceed 52 C. Store full
and empty cylinders separately. Use a first-in, first-out inventory system to prevent storing full cylinders for long
periods.
PRECAUTIONS TO BE TAKEN IN HANDLING:
Protect cylinders from damage. Use a suitable hand truck to move cylinders; do not drag, roll, slide, or drop. Never
attempt to lift a cylinder by its cap; the cap is intended solely to protect the valve. Never insert an object (e.g., wrench,
screwdriver, pry bar) into cap openings; doing so may damage the valve and cause a leak. Use an adjustable strap
wrench to remove over-tight or rusted caps. Open valve slowly. If valve is hard to open, discontinue use and contact
your supplier.
For additional information on stroage and handling, refer to Compressed Gas Association (CGA) pamphlet P-1, Safe
Handling of Compressed Gases in Containers, available from the CGA. Refer to Section 16 for the address and phone
number along with a list of other available publications.

Mixture
OTHER HAZARDOUS CONDITIONS OF HANDLING, STORAGE, AND USE:
High pressure gas. Use piping and equipment adequately designed to withstand pressures to be encountered. Gas
can cause rapid suffocation due to oxygen deficiency. Store and use with adequate ventilation. Close valve after
each use; keep closed even when empty. Prevent reverse flow. Reverse flow into cylinder may cause rupture. Use a
check valve or other protective device in any line or piping from the cylinder. Never work on a pressurized system. If
there is a leak, close the cylinder valve. Blow the system down in an environmentally safe manner in compliance with all
federal, provincial, and local laws, then repair the leak. Never place a compressed gas cylinder where it may
become part of an electrical circuit.
