TIME WEIGHTED AVERAGE EXPOSURE LIMIT
5,000 Molar PPM with an STEL of 30,000 Molar PPM; Nitrogen is a simple asphyxiant
(ACGIH 1999). OSHA 1998 PEL (8 Hr. TWA) (Continued on Page 4)
SYMPTOMS OF EXPOSURE
Depending on levels and duration of exposure, symptoms may
include headache, dizziness, heart palpitations, weakness, confusion and nausea to convulsions, eventual
unconsciousness and death. Because carbon monoxide is a colorless and odorless poisonous gas, there is no warning
of its presence other than the above symptoms. Analytical monitors, with alarms, should be employed where the
possibility of the release of toxic quantities exists. (Continued on Page 4)
TOXICOLOGICAL PROPERTIES
The oxygen transport function of the hemoglobin of the blood is reduced since it reacts with inhaled carbon monoxide
to form carboxy hemoglobin instead of its normal reaction with the oxygen in the lungs to form oxyhemoglobin. The
affinity of hemoglobin for carbon monoxide is 200-300 times greater than its affinity for oxygen. All the disorders are
due to the markedly reduced cellular respiration and may include central nervous system impairment, cardiovascular
collapse, renal insufficiency, coma, etc.
Neither carbon monoxide, carbon dioxide or nitrogen are listed in IARC, NTP or by OSHA as a carcinogen or potential
carcinogen.
Persons in ill health where such illness would be aggravated by exposure to thtse:mixtures should not be allowed to
work with or handle these products.
RECOMMENDED FIRST AID TREATMENT
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE T0 THIS MIXTURE.
RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS.
Inhalation: Conscious persons should be assisted to an uncontaminated area and be treated with supplemental
oxygen. Quick removal from the contaminated area is most important. Unconscious persons should be moved to an
uncontaminated area and be given assisted respiration and oxygen at the same time. The administering of the oxygen
at an elevated pressure (up to 2 - 2.5 atmospheres) has shown to be beneficial as has treatment in a hyberbaric
chamber. The physician should be informed that the patient has inhaled toxic quantities of carbon monoxide.

STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED
Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user鈥檚 equipment, be
certain to purge piping with an inert gas prior to attempting repairs. If leak is in container or container valve, contact
your closest supplier location or call the emergency telephone number listed herein.
WASTE DISPOSAL METHOD
Do not attempt to dispose of waste or unused quantities. Return in the shipping container properly labeled, with any
valve outlet plugs or caps secured and valve protection cap in place to your supplier. For emergency disposal
assistance, contact your closest supplier location or call the emergency telephone number listed herein.

SPECIAL HANDLING RECOMMENDATIONS
Use only in well-ventilated areas. Valve protection caps must remain in place unless container is secured with valve
outlet piped to use point. Do not drag, slide, or roll cylinders. Use a suitable hand truck for cylinder movement. Use a
pressure reducing regulator when connecting cylinder to lower pressure (<3,000 psig) piping or systems. Do not heat
cylinder by any means to increase the discharge rate of product from the cylinder. Use a check valve or trap in the
discharge line to prevent hazardous back flow into the cylinder.
For additional handling recommendations, consult Compressed Gas Associations鈥? Pamphlets P-1.
SPECIAL STORAGE RECOMMENDATIONS
Protect cylinders from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked areas and
emergency exits. Do not allow the temperature where cylinders are stored to exceed 125潞F (52潞C). Cylinders should be
stored upright and firmly secured to prevent falling or being knocked over. Full and empty cylinders should be
segregated. Use a 鈥渇irst in - first out鈥? inventory system to prevent full cylinders being stored for excessive periods of
time.
For additional storage recommendations, consult Compressed Gas Association鈥檚 Pamphlets P-1.
SPECIAL PACKAGING RECOMMENDATIONS
Carbon monoxide can be handled in all commonly used metals up to approximately 500 psig (3450 kPa). Above that
pressure it forms toxic and corrosive carbonyl compounds with some metals. Carbon steels, aluminum alloys, copper
and copper alloys, low carbon stainless steels and nickel-based alloys such as Hastelloy庐 A, B and C are
recommended for higher pressure applications.
OTHER RECOMMENDATIONS OR PRECAUTIONS
Compressed gas cylinders should not be refilled except by qualified producers of compressed gases. Shipment of a
compressed gas cylinder which has not been filled by the owner or with his (written) consent is a violation of Federal
Law (49CFR). Always secure cylinders in an upright position before transporting them. NEVER transport cylinders in
trunks of vehicles, enclosed vans, truck cabs or in passenger compartments. Transport cylinders secured in open
flatbed or in open pick-up type vehicles. Reporting under SARA. Title III, Section 313 not required.
