HEALTH HAZARD DATA
TIME WEIGHTED AVERAGE EXPOSURE LIMIT
These gas mixtures contain varying quantities of gaseous carbon dioxide. Carbon dioxide
has a TWA of 5,000 Molar PPM. Its STEL is 30,000 Molar PPM (Continued on Page 4)
SYMPTOMS OF EXPOSURE
Concentrations of 20-30 percent of these mixtures when inhaled with adequate oxygen in the air will cause an increase
in the respiratory rate. Higher concentrations will cause headache, nausea and eventual uncons~iousness.
TOXICOLOGICAL PROPERTIES
Carbon dioxide is the most powerful cerebral vasodilator known. Inhaling large concentrations causes rapid circulatory
insufficiency leading to coma and death. Chronic harmful effects are not known from repeated inhalation of low
(20-30%) concentrations of these mixtures.
Neither carbon dioxide or nitrogen are listed in the IARC, NTP or by OSHA as a carcinogen or potential carcinogen.
Persons in ill health where such illness would be aggravated by exposure to these mixtures should not be allowed to
work with or ha~dle these products.
RECOMMENDED FIRST AID TREATMENT
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF 0VEREXP0SURE T0 THESE MIXTURES.
RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS.
Inhalation: Consciuos persons should be assisted to an uncontaminated area and inhale fresh air. Quick removal from
the contaminated area is most important. Unconscious persons should be moved to an uncontaninated area, given
assisted respiration and supplemental oxygen. Further treatment should be symptomatic and supportive.

Evacuate all personnel from affected area. Use approiate protective equipmemt. 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 attempl to dispose of waste or unused quantities. Return in the shipping con
tainer properly labeled, with any valve outlet plugs or caps secured and valve protec
tion cap in place to your supplier. For emergency disposal assistance, contact your

SPECIAL HANDLING RECOMMENDATIONS
Use only in well-venilated areas. Valve protection caps must remain in place unless container is secured with valve
outlet piped to use point. Do not drag, slide, drop 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 sysr.ems. Du
I;UL hErIC cyl inuei- by a,,y means tG inCr ease thc discharge rat^ of product from the cylinder. Use a check valve or
trap in the discharge line tc prevent hazardous back flow into the cylinder. Keep cylinder away from heat and flame. Do
not tamper with (valve) safety device. Close valve after each use and when empty.
SPECIAL STORAGE RECOMMENDATIONS
Protect cylinders from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked areas and
emergency exits. Go not allow the temperature where cylinders are stored to exceed 125F (52C). Cylinders should be
stored upright and firmly secured to prevent falling or being knocked over. Full and empty cylinders I should be
segregated. Use e 鈥渇irst in- first out鈥? inventory system to prevent full I cylinders being stored for excessive periods of
time.
For additional recommendations consult Compressed Gas Association鈥檚 Pamphlet P-1.
SPECIAL PACKAGING RECOMMENDATIONS
These mixtures are noncorrosive and may be used with any common structural material.
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).
