HEALTH HAZARD DATA
Sulphur Dioxide TWA = 2 Molar PPM with an STEL of 5 Molar PPM and an A4 (Not Classifiable
TIME WEIGHTED AVERAGE EXPOSURE LIMIT
as a Human Carcinogen) carcinogen rating; Nitric Oxide TWA = 25 Molar PPM; Nitrogen is a
simple asphyxiant (ACGIH 1999). OSHA 1998 (Continued on Page 4)
SYMPTOMS OF EXPOSURE
The amounts of sulphur dioxide and nitric oxide present in these mixtures, unless breathed continuously with adequate
oxygen, should not present a toxicological problem. Nitrogen as a simple asphyxiant could cause symptoms of
asphyxia if breathed without adequate oxygen (displace the oxygen necessary to support life).
TOXICOLOGICAL PROPERTIES
These mixtures are relatively non-toxic (See Symptoms of Exposure).
None of the compounds in these mixtures 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 handle these products.
RECOMMENDED FIRST AID TREATMENT
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE T0 THESE MIXTURES.
RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS.
Inhalation: Conscious 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 uncontaminated area, given
assisted respiration and supplemental oxygen. Further treatment should be symptomatic and supportive.

DOT Shipping Label: Nonflammable Gas I.D. No. UN 1956
SPECIAL HANDLING RECOMMENDATIONS
Use only in well-ventilated areas. Valve protection caps must remain in place unless cylinder 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 the 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, P-9, P-14 and
Safety Bulletin SB-2.
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, P-9, P-14 and Safety
Bulletin SB-2.
SPECIAL PACKAGING RECOMMENDATIONS
These mixtures are noncorrosive and may be used with any common structural materials.
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.
