3. Hazards Identification
Emergency Overview
WARNING! High-pressure gas. Can cause rapid suffocation. May cause dizziness and drowsiness.
Self-contained breathing apparatus may be required by rescue workers.
Inhalation.
ROUTES OF
EXPOSURE:
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:
INHALATION: Asphyxiant. Effects are due to lack of oxygen. Moderate concentrations may cause
headaches, drowsiness, dizziness, excitation, excess salivation, vomiting, and
unconciousness. Lack of oxygen can kill.
SKIN CONTACT: No harm expected from vapour.
No evidence of adverse effects from available information.
SKIN
ABSORPTION:
SWALLOWING:
This product is a gas at normal temperature and pressure.
EYE CONTACT:
No harm expected from vapour..
EFFECTS OF REPEATED (CHRONIC) OVEREXPOSURE:
Not available.
OTHER EFFECTS OF OVEREXPOSURE:
None known.
MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE:
The toxicology and the physical and chemical properties of this product suggest that overexposure is unlikely to
aggravate medical condition.
SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH HAZARD EVALUATION:
None currently known.
CARCINOGENICITY:
Not listed as carcinogen by OSHA, NTP or IARC.

4. First Aid Measures
INHALATION:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get
medical attention.
SKIN CONTACT:
This product is a gas at normal temperature and pressure.
SWALLOWING:
This product is a gas at normal temperature and pressure.
EYE CONTACT:
This product is a gas at normal temperature and pressure.
NOTES TO PHYSICIAN:
There is no specific antidote. Treatment of over-exposure should be directed at the control of symptoms and the clinical
condition.
5. Fire Fighting Measures

FLAMMABLE LIMITS LOWER: UPPER:
IN AIR, % by volume:
EXTINGUISHING MEDIA:
This mixture cannot catch fire. Use media appropriate for surrounding fire.
SPECIAL FIRE FIGHTING PROCEDURES:
WARNING! 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. Self-contained breathing apparatus may be
required by rescue workers. If containers are leaking, reduce vapours with water spray or fog. Shut off leak
if without risk. Move containers away form fire area if without risk.
UNUSUAL FIRE AND EXPLOSION HAZARD:
Nonflammable material. This material cannot catch fire. Container may rupture due to heat of fire. No part of a
container should be subjected to 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. Toxic fumes may be produced when
heated.
HAZARDOUS COMBUSTION PRODUCTS:
None known.
SENSITIVITY TO IMPACT:
Avoid impact against container.
SENSITIVITY TO STATIC DISCHARGE:
Not applicable.

6. Accidental Release Measures
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED:
WARNING! High-pressure gas. Evacuate all personnel from danger area. Use self-contained breathing apparatus
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.
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, provincial, 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. Separate flammable cylinders from oxygen, chlorine, and other oxidizers by at
least 6.1 m or use a barricade of non-combustible material. This barricade should be at least 1.53 m high and have a
fire resistance rating of at least ?hour. Firmly secure cylinders upright to keep them from falling or being knocked
over. Screw valve protection cap firmly in place by hand. Post "No Smoking or Open Flames" signs in storage and use
areas. There must be no sources of ignition. All electrical equipment in storage areas must be explosion-proof.
Storage areas must meet national electric codes for Class 1 hazardous areas. Store only where temperature will not
exceed 125癋(52癈). Store full and empty cylinders separately. Use a first-in, first-out inventory system to prevent
storing full cylinders for long periods. For full details and requirements, see NFPA 50A, published by the National Fire
Protection Association.
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 other precautions, see section 16.
For additional information on storage 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.
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. When returning cylinder to supplier, be
sure valve is closed, then install valve outlet plug tightly. Never work on pressurized system. If there is a leak, close
the cylinder valve. Vent the system down in a safe and environmentally sound 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.

Product Name: Carbon monoxide MSDS# E-6809-F Date: 10/15/2007
mixture, non-toxic
RESPIRATORY PROTECTION: For concentrations up to 10 times the applicable exposure limit
any NIOSH/MSHA approved supplied air respirator is
recommended. Up to 50 times the TLV, a NIOSH/MSHA
approved respirator with a full-face piece or self-contained
breathing apparatus is recommended. For higher concentration
us only self-contained breathing apparatus operated in the
pressure demand mode.. Selection should also be based on the
current CSA standard Z94.4, "Selection, Care and Use of
Respirators". Respirators should also be approved by NIOSH and
MSHA.
SKIN PROTECTION: Wear work gloves when handling cylinders.
EYE PROTECTION: Wear safety glasses when handling cylinders.
Select in accordance with the current CSA standard Z94.3,
"Industrial Eye and Face Protection", and any provincial
regulations, local bylaws or guidelines.
OTHER PROTECTIVE EQUIPMENT: Metatarsal shoes for cylinder handling. Protective clothing where
needed. Cuffless trousers should be worn outside the shoes.
Select in accordance with the current CSA standard Z195,
"Protective Foot Wear", and any provincial regulations, local
bylaws or guidelines.
