EMERGENCY OVERVIEW
MSDS: G-238
Revised: 10/16/96 Page 1 of 7
PRODUCT NAME: LASER GAS MIXTURE
This product does not contain oxygen and may cause asphyxia if released in a confined area. Inhaled
Carbon monoxide binds to the blood hemoglobin, greatly reducing the red blood cell鈥檚 ability to
transport oxygen to body tissues. Effects may include headaches, dizziness, convulsions, loss of
consciousness and death. Carbon dioxide may cause nausea and vasodilation. Contents under
pressure. Use and store below 120 掳F. Nonflammable.

EYE EFFECTS:

SKIN EFFECTS:

INGESTION EFFECTS:
None reported.
INHALATION EFFECTS:
If released in a confined area this product may displace oxygen and result in asphyxia.
Inhaled carbon monoxide binds with blood hemoglobin to form carboxyhemoglobin. Carboxyhemoglobin can
not take part in normal oxygen transport, greatly reducing the blood鈥檚 ability to transport oxygen. Depending on
levels and duration of exposure, symptoms may include headache, dizziness, heart palpitations,weakness,
confusion, nausea, and even convulsions, eventual unconsciousness and death.
Carbon dioxide exposure can cause nausea and respiratory problems. High concentrations may cause
vasodilation and respiratory collapse, although this is an unlikely result at the concentration contained in this
product mixture.
Some experimental evidence indicates teratogenic and reproductive effects from carbon dioxide exposure.
Oxygen deficiency during pregnancy has produced developemental abnormalities in humans and experimental
animals.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:

4. First Aid Measures
EYES:
None required.
SKIN:
None required.
INGESTION:
None required.
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 artificial respiration and oxygen at the same time. The administering of the
oxygen at an elevated pressure (up to 2 to 2.5 atmospheres) has shown to be beneficial as has treatment in a
hyperbaric chamber. The physician should be informed that the patient has inhaled toxic quantities of carbon
monoxide. PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE
TO CARBON MONOXIDE. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED
BREATHING APPARATUS.

FIRE FIGHTING INSTRUCTIONS:
If possible, stop flow of gas; use water spray to cool surrounding containers. Continue to cool flame exposed
containers untill well after flames have been extinguished.

6. Accidental Release Measures
Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user鈥檚 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
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
A, B & C are recommended for higher pressure applications.
Protect cylinders from physical damage. Store in cool, dry, well-ventilated areas away from heavily trafficked
areas and emergency exits. Do not allow the temperature where cylinders are stored to exceed 120oF (49oC).
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
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 (<3000 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 system.
Never carry a compressed gas cylinder or a container of a gas in cryogenic liquid form in an enclosed space such
as a car trunk, van or station wagon. A leak can result in a fire, explosion, asphyxiation or a toxic exposure.

11. Toxicological Information
REPRODUCTIVE:
Inhalation of 150 ppm carbon monoxide for 24 hours by pregnant rats produced cardiovascular and behavioral
defects in offspring. Toxic effects to fertility were observed in female rats exposed to 1 mg/m3 for 24 hours.
Similar effects observed in other mammalian species.
Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimental
animals.
Exposure of female rats to 60,000 ppm carbon dioxide for 24 hours has produced toxic effects to the embryo and
fetus in pregnant rats. Toxic effects to the reproductive system have been observed in other mammalian species
at similar concentrations.
