TIME WEIGHTED AVERAGE EXPOSURE LIMIT
5,000 Molar PPM; STEL                = 30,000        Molar PPM (ACGIH 1994-199S).                           OSHA 1993 PEL (8 Hr. TWA)
= S,OOO Molar PPM.
SYMPTOMS OF EXPOSURE
Inhalation: Low concentrations (3-5 molar ~) cause increased respiration and headache.
Eight to 15 molar % concentrations cause headache, nausea and vomiting which may lead to
unconsciousness if not moved to open air or given oxygen.
High concentrations cause rapid circulatory insufficiency leading to coma and death.
TOXICOLOGICAL PROPERTIES
Carbon dioxide is the most powerful cerebral vasodilator known. Inhaling large concen-
trations causes rapid circulatory insufficiency leading to coma and death. Chronic,
harmful effects are not known from repeated inhalation of low (3-S molar %)
concentra t ions.
Carbon dioxide. is not 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 carbon
dioxide should not be allowed to work with or handle this product.
RECOMMENDED FIRST AID TREATMENT

PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO CARBON DIOXIDE.
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. Assure that vomited material does not obstruct the airway by use
of positional drainage. Further treatment should be symptomatic and supportive.

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 «1500 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 addition~l handling recommendations, consult Compressed Gas Association's Pamphlets
P-1, G-6, G-6.1, and G-6.2.
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 125F (52C). 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 being stored for excessive period~ of time.
For additional storage recommendations, consult Compressed Gas Association's Pamphlets
P-1, G-6, G-6.1, and G-6.2

SPECIAL PACKAGING RECOMMENDATIONS

Dry carbon dioxide can be handled with most common structural materials. Moist carbon
dioxide is corrosive by its formation of carbonic acid. For these applications, 316,
309 and 310 stainless steels may be used as well as Hastelloy® A, Band C and Monel®.
Ferrous nickel alloys are slightly c,orroded.
At normal temperatures carbon dioxide is compatible with most plastics and elastomers.

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).

                                                                                                                            (Continued on Page                     ~1

SPECIAL PRECAUTIONS
OTHER RECOMMENDATIONS OR PRECAUTIONS:     (Continued)
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.

SYMPTOMS OF EXPOSURE

  Route of entry is through inhalation. Effects of exposure to high concentrations so
  as to displace the oxygen in the air necessary to support life are headache, dizziness,
  increased or labored breathing and eventual unconsciousness and suffocation. Breathing
  this gas mixture with adequate oxygen could cause an increase in respiration and heart
  rate.
TOXICOLOGICAL PROPERTIES

  Mixtures are nontoxic but the liberation of a large amount in a confined area could
  displace the amount of oxygen in air necessary to support life.
  None of the gases in these mixtures are listed in the IARC, NTP or by OSHA as a carcino-
  gen or a potential carcinogen.
  Persons in ill pealth where such illness would be aggravated by exposure to these
  mixtures should not be a,lowed to work with or handle these products.

RECOMMENDED FIRST AID TREATMENT

   PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO 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.

 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, 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
  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. Keep cylinder away from heat and flame. Do not tamper
  with (valve) safety device. Close valve after each use and when empty. See NFPA
  Pamphlet 51A "Welding and Cutting" for additional information.
  For additional recommendations consult Compressed Gas Association's Pamphlet P-l.
 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 125F (52C). 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
  cylinde~s being stored for exc~ssive periods of time.

  For additional recommendations consult Compressed Gas Association's Pamphlet P-l.

 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 com-
  pressed 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).

                                                                                                                                 (Cant i nued on Page 5 )

                       SPECIAL PROTECTION INFORMATION
                       LOCAL EXHAUST:
                       To prevent accumulation of high concentrations of gases so as to reduce the oxygen
                       level in the air to less than 18 molar percent. When welding, use enough ventila-
                       tion, local exhaust at the arc, or both, to keep the welding fumes and gases below
                       the applicable TLVs in the worker's breathing zone and the general area. Train
                       the welder to keep his head out of the fumes.
                       EYE PROTECTION: (Continued)
                       shield with filter lens. As a general rule, start        with a shade which is too dark
                       to see the weld zone. Then go to the next lighter        shade which gives sufficient
                       view of the weld zone. Provide protection screens        and flash goggles, if necessary,
                       to shield others from arc rays radiation which can       injure eyes and burn skin.
                       OTHER PROTECTIVE EQUIPMENT: (Continued)
                       When welding, wear head, hand and body protection which help to prevent injury from
                       radiation, sparks and electrical shock. See ANSI Z-49.1. At a minimum, this
                       includes welder's gloves and a protective face shield and may include arm protectors,
                       aprons, hats, shoulder protection, as well as dark substantial clothing. Train the
                       welder not to touch live electrical parts and to insulate himself from work and
                       ground.
                       CAUTION: Welding or brazing may produce fumes and gases hazardous to health.
            -~   ..
                  ~-   Short-term (acute) overexposure to welding fumes may result in discomfort such as:
                       dizziness, nausea, or dryness or irritation of nose, throat, or eyes. Long-term
                       (chronic) overexposure may lead to siderosis (iron deposits in the lungs) and is
                       believed by some investigators to affect pulmonary function. Arc rays can injure
                       eyes and burn skin. Electric shock can kill. Avoid breathing these fumes and
                       gases. Use adequate ventilation. See ANSI Z-49.1 "Safety in Welding and Cutting"
                       published by the American Welding Society.
                       Consult hazard warnings on boxes or containers (or on tags or labels thereon) con-
                       taining brazing or welding filler metals, fluxes and fusible granular materials.
                       See OSHA safety regulations under 29CFR 1910.252 "Welding, Cutting and Brazing."

                       further information.
                       Consult manufacturer's material safety data sheet on welding consumables and
                       related products for reactivity and health hazard data, and for further information

TIME WEIGHTED AVERAGE EXPOSURE LIMIT
Argon is defined as a simple asphyxiant (ACGIH 1994-1995).                                                     No PEL (8 Hr. TWA) is
listed by OSHA (1993).                                                                                               (Continued on Page 4)
SYMPTOMS OF EXPOSURE
Effects of exposure to high concentrations so as to displace the oxygen ;n air necessary
for .1 ife may include !!!l" all, or ~ of the following:
       • Loss of balance or dizziness
       • Tightness in the frontal area of the forehead
                                                                 (Continued on Page 4)
TOXICOLOGICAL PROPERTIES

Argon is nontoxic but the liberation of a large amount in a confined area could displace
the amount of oxygen in air necessary to support life.
Argon is not 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 argon
should not be allowed to work with or handle this product.

RECOMMENDED FIRST AID TREATMENT


PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO ARGON.                                                                   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.

     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. 00 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.
     00 not heat cylinder by any means to increase the discharge rate of product from the
     cyl inder. Use a check val ve or trap in the di scharge 1 ine to. prevent hazardous back
     flow into the cylinder.
     For additional recommendations, consult Compressed Gas Association's 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. 00 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
     should be segregated. Use a "first in - first out" inventory system to prevent full
     cylinders being stored for excessive periods of time.

HEALTH HAZARD DATA
TIME WEIGHTED AVERAGE EXPOSURE LIMIT:               (Continued)
Oxygen levels should be maintained at greater than 18 Mut'ar percent at
normal atmospheric pressure (p02>135 torr).

SYMPTOMS OF EXPOSURE:            (Continued)
          •    Tingling in the tongue, fingertips or toes
          •    Weakened speech leading to the inability to utter sounds
          •    Rapid reduction in the ability to perform movements
          •    Reduced consciousness of the surroundings
          •    Loss of tactile sensations
          •    Heightened mental activity
It should be recognized that it is possible that none of the above symptoms
may occur in argon asphyxia so that there are no definite warning symptoms.


SPECIAL PROTECTION INFORMATION
LOCAL EXHAUST:
To prevent accumulation of high concentrations so as to reduce the oxygen
level in the air to less than 18 molar percent.


SPECIAL PRECAUTIONS
OTHER         RECOMt·1ENDATIONS~OR   PRECAUTIONS:   (Continued)
Always secure cylinders in an upright position before transporting them.

 TIME WEIGHTED AVERAGE EXPOSURE LIMIT

 No TWA established (ACGIH 1994-1995).                                 No PEL (8 Hr. TWA) listed by OSHA 1993.
 SYMPTOMS OF EXPOSURE

 Air is nontoxic and necessary to support life. Inhalation of air in a high pressure
 environment such as underwater diving, caissons or hyperbaric chambers can result in
 symptoms similar to overexposure to pure oxygen. These include tingling of fingers
 and toes, abnormal sensations, impaired coordination and confusion. Decompression
 sickness, pains or "bends" are possible following rapid decompression.
 TOXICOLOGICAL PROPERTIES



 High pressure effects (greater than two atmospheres of oxygen) are on the central nervous
 system. Improper decompression results in the accumulation of nitrogen in the blood.

 Air is not listed in thp IARC, NTP or by OSHA as a carcinogen or potential carCinogen.
 Persons in ill health whei:" -: r.h ill ness waul d be aggravated by exposure to high
 pressure air should not be allowed to work with or handle this product.
 RECOMMENDED FIRST AID TREATMENT




 Facilities or practices at which air is breathed in a high pressure environment should
 be prepared to deal with the illnesses associated with decompression (bends or caisson
 disease). Decompression equipment may be required.

    SPECIAL FIRE FIGHTING PROCEDURES

    If cylinders are involved in a fire, safely relocate or keep cool with water spray.

    UNUSUAL FIRE AND EXPLOSION HAZARDS

    Compressed air at high pressures will accelerate the burning of materials to a greater
    rate than they burn at atmospheric pressure.

SPECIAL HANDLING RECOMMENDATIONS

Valve protection caps must remain in place unless container is secured with valve outle'
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 the Compressed Gas Association's
Pamphlets P-1, G-7, and G-7.1.

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 125F (52C). 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 being stored for excessive periods of time.
For additional storage recommendations, consult the Compressed Gas Association's
Pamphlets P-1, G-7, and G-7.1.

SPECIAL PACKAGING RECOMMENDATIONS


Dry air is noncorrosive and may be used with all materials of construction. Moisture
causes' metal oxides which are formed with air to be hydrated so that they increase in
volume and lose their protective role (rust formation). Concentrations of S02' C12,
sal t ,etc . in the moisture enhances the rus ti ng of metal sin ai r.

                                                                                                               '   .

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).

     TIME WEIGHTED AVERAGE EXPOSURE LIMIT
     Acetylene is defined as a simple asphyxiant !ACGIH 1994-1995).                                                   No PEL (8 Hr. TWA) is
     1i sted by OSHA (1993).                     \                                                                        (Continued on Page 4
     SYMPTOMS OF EXPOSURE


     Inhalation: Low concentrations (10-20% in air) cause symptoms similar to that of being
     intoxicated. Higher concentrations so as to exclude an adequate supply of oxygen to tho
     lungs cause unconsciousness.
(
     TOXICOLOGICAL PROPERTIES
     As a narcotic gas or intoxicant causes hypercapnia (an excessive amount of carbon dioxi'
     in the blood). Repeated exposures to tolerable levels has not shown deleterious effect:
     The major property is the exclusion of an adequate supply of oxygen to the lungs.
     Acetylene is not listed in the IARC, NTP or by OSHA as a carcinogen or potential
     carci nogen.
     Per$o~s in ill health wher~ such illness would be aggravated by exposure to acetylene
     should not be allowed to work with or handle this product.
     RECOMMENDED FIRST AID TREATMENT             .

     PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO ACETYLENE. RESCUe
     PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS AND BE COGNIZAHT Or
     EXTREME FIRE AND EXPLOSION HAZARD.

     Inhalation: Conscious persons should be assisted to an uncontaminated area and inhale
     fresh air. Quick removal from .contaminated area is most important. Unconscious

 SPECIAL HANDLING RECOMMENDATIONS
 Use only in well-ventilated areas. Valve protection caps must remain in place unless
 containe~is secured with valve outJet piped to use point. Do not drag, slide or roll
 cylinders; U~e a suitable hand truck for cylinder movement. Use a pressure reducing
  regulator. when ,removing gas from the cylinder. DO NOT ALLOW THE FREE GAS TO EXCEED
 30 PSIA (207 kPa) @ 70°F (21.10C). Do not heat cylinder by any means to increase the     ,
 dischar.ge.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 recommendations, consult Compressed Gas Association's Pamphlets G-l, P-l,:

I SPECIAL STORAGE- RECOMMENOATIONS ..
  Protect. cylinders from physical damage. Store in cool, dry, well-ventilated'area of
  noncombustible construction away from heavily trafficked areas and emergency exits. Do
  not allow the temperature where cylinders are stored to exceed 125F (52C). Cylinders
  must be' stored' upright and firmly secured to prevent fall ing or being knocked over.
  Full and empty cylinders should be segregated. Use a IIfirst in - first out inventory                                                                                    ll

  Since acetylene'will explode-or combust if its pressure exceeds 30 psia (207 kPa) it is
  shipped dissolved in acetone or dimethylformamide which is dispersed in a porous mass
  within the cylinder. Follow your supplier's instructions for the maximum withdrawal
  rate for each size cylinder so that solvent is not withdrawn with the acetylene.
  Most metals except silver, copper, mercury or brasses with more than 66% copper are
  compatible (noncorrosive) with acetylene.
 OTHER RECOMMENDATIOFJS'OR PRECAUTIONS               ~

  Earth-ground and bond all lines and equipment associated with the acetylene system.
  Electrical equipment should be non-sparking or explosion proof. 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 (l'/ritten) consent is a violation of Federal Law (49CFR).

FIRE AND EXPLOSION HAZARD DATA
UEL:    (Cont i nued)
Pure acetylene can ignite by decomposition above 30 psia (207 kPa); therefore,
the UEL is 100% if the ignition source is of sufficient intensity.

UNUSUAL FIRE AND EXPLOSION HAZARDS:                 (Continued)
extinguished without stopping the flow of gas can easily reignite with possible
explosive force. Acetylene has a density very similar to that of ajr so when
leaking it does not readily dissipate.
