3. Hazards Identification
EMERGENCY OVERVIEW
Colorless flammable gas with slight petroleum odor. Dangerous fire and explosion hazard. Avoid
heat, sparks and flames. The majority of this product consists of simple asphyxiants which displace
oxygen necessary to support life. Release in confined area may cause suffocation. Simple
hydrocarbons may cause irritation and central nervous system depression at high concentrations.
Maintain oxygen levels above 19.5%. Contents under pressure. Use and store below 125 癋.

PRODUCT NAME: NATRUAL GAS REFERENCE STANDARDS
(GPA GAS REFERENCE, HIGH HELIUM, AND HIGH ETHANE)
INGESTION EFFECTS: None known. Ingestion is unlikely.
INHALATION EFFECTS: High concentrations may irritate the eyes and mucous membranes. Methane,
ethane, nitrogen, propane, and helium act as simple asphyxiants. Exposure to high concentrations of this gas
mixture may exclude an adequate supply of oxygen. High concentrations of simple hydrocarbons present in this
mixture may have a narcotic effect. Overexposure to hydrocarbons is expected before overexposure to carbon
dioxide.
Narcotic effects may include dizziness, incoordination, sleepiness, and unconsciousness. Effects of oxygen
deficiency resulting from simple asphyxiants may include: rapid breathing, diminished mental alertness,
impaired muscular coordination, faulty judgement, depression of all sensations, emotional instability, and
fatigue. If victim is not removed from exposure, unconsciousness may result eventually leading to convulsions,
coma, and death.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: None known.
POTENTIAL ENVIRONMENTAL EFFECTS: Ecotoxicity values were unavailable. Toxic effects are
expected to be similar to those seen in humans and test animals.
4. First Aid Measures
EYES: If irritation occurs, rinse eyes thoroughly with lukewarm water. If irritation persists, seek medical
attention.
SKIN: If irritation occurs, wash skin thoroughly with soap and water.
INGESTION: Not normally required.
INHALATION: PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
OVEREXPOSURE TO THIS PRODUCT. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-
CONTAINED BREATHING APPARATUS. Victims should be assisted to an uncontaminated area and inhale
fresh air. Quick removal from the contaminated area is most important. If breathing has stopped administer
artificial resuscitation and supplemental oxygen. Further treatment should be symptomatic and supportive.
Keep victim warm and quiet.

MSDS: G-458
Revised: 11/8/02 Page 3 of 7
PRODUCT NAME: NATRUAL GAS REFERENCE STANDARDS
(GPA GAS REFERENCE, HIGH HELIUM, AND HIGH ETHANE)
EXTINGUISHING MEDIA: Carbon dioxide, dry chemical or water spray.
FIRE FIGHTING INSTRUCTIONS: If possible, stop the flow of gas. Inerting the atmosphere to reduce
oxygen levels may extinguish flame, allowing capping of leaking container. Do not attempt this unless
specifically trained. Reduce the rate of flow and inject an inert gas, if possible, before completely stopping the
flow to prevent flashback. Do not extinguish the fire until the supply is shut off as otherwise an explosive re-
ignition may occur. If the fire is extinguished and the flow of gas continues, use increased ventilation to prevent
build-up of explosive atmosphere. Use non-sparking tools to close container valves.
Use water spray to cool surrounding containers. Be cautious of a Boiling Liquid Evaporating Vapor Explosion,
BLEVE, if flame is impinging on surrounding containers. Direct 500 GPM water stream onto containers above
liquid level with remote monitors. Limit the number of personnel in proximity of fire and evacuate surrounding
areas in all directions.
Firefighters should wear respiratory protection (SCBA) and full turnout or Bunker gear. Continue to cool fire-
exposed cylinders until well after flames are extinguished.
6. Accidental Release Measures
Immediately extinguish all ignition sources. No smoking, flames, sparks or flares in hazard area. Evacuate all
personnel from affected area. Use appropriate protective equipment (See Section 8). Stop the flow of gas or
remove cylinder to outdoor location if this can be done without risk. Ventilate enclosed areas. Provide
maximum explosion-proof ventilation. If leak is in user's equipment, be certain to purge piping with inert gas
prior to attempting repairs. If leak is in container or container valve, contact the appropriate emergency
telephone number listed in Section 1 or call your closest BOC location.
7. Handling and Storage
Electrical Classification: Not Available
Earth ground and bond all lines and equipment associated with the system. All equipment should be non-
sparking or explosion-proof. Methane is non-corrosive and may be used with any common structural material.
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 regulator when connecting cylinder to lower pressure 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. Do not insert any object (i.e.: screwdriver)
into valve cap openings as this can damage the valve causing leakage.
Protect cylinders from physical damage. Store in cool, dry, well-ventilated area of non-combustible construction
away from heavily trafficked areas and emergency exits. Do not allow the temperature where cylinders are
stored to exceed 125oF (52oC). Cylinders should be stored upright and firmly secured to prevent falling or being
knocked over. Full and empty cylinders should be segregated. Use a "first in-first out" inventory system to
prevent full cylinders from being stored for excessive periods of time. Post "NO SMOKING" signs in use or
storage areas. There should be no source for accidental ignition in areas where this product is being used or
stored. Outside or detached storage is preferred.
For additional storage recommendations, consult Compressed Gas Association's Pamphlets P-1, P-14, and Safety
Bulletin SB-2.

8. Exposure Controls, Personal Protection
ENGINEERING CONTROLS: Use local exhaust and general ventilation systems to prevent build up of
flammable concentrations. Small quantities can be handled in forced ventilation hoods. If product is handled
routinely where the potential for leaks exists, all electrical equipment must be rated for use in potentially
flammable atmospheres. Consult the National Electrical Code for details.
EYE/FACE PROTECTION: Safety goggles or glasses.
SKIN PROTECTION: Protective gloves of suitable material as necessary to prevent exposure.
RESPIRATORY PROTECTION: For emergency release use a positive pressure NIOSH approved air-
supplying respirator systems (SCBA or airline/escape bottle) using at a minimum Grade D air.
OTHER/GENERAL PROTECTION: Safety shoes.

11. Toxicological Information
INHALATION: In humans, pentane has caused slight dizziness in humans at concentrations of 5000 ppm (10
minute exposure) but no noticeable nose, eye or respiratory irritation. Individuals exposed to 10,000 ppm (1%)
butane for 10 minutes exhibited drowsiness but no systemic effects. The ACGIH TLV for carbon dioxide of
5,000 ppm is expected to provide a good margin of safety from asphyxiation and undue metabolic stress
provided sufficient oxygen levels are maintained in the air. Increased physical activity, duration of exposure,
and decreased oxygen content can affect systemic and respiratory effects resulting from exposure to carbon
dioxide.
SKIN AND EYE: May cause minor eye irritation.
OTHER: Long-term adverse effects have been noted for mixtures containing pentane and other volatile
hydrocarbons (polyneuropathy). Similar effects have not been reported for pure pentane or butane. Pentane in
solvent mixtures may potentiate hexacarbon neuropathy possibly due to smaller amounts of n-hexane and MBK
present.
Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimental
animals. Chronic, harmful effects are not known from repeated inhalation of low (3 to 5 molar %)
concentrations of carbon dioxide.
12. Ecological Information
