Percent (by weight)90.0% 100.0%
ACGIH - STELS5000ppm
_Emergency Overview_
Danger:High pressure liquid and gas. Can cause rapid suffocation. Can increase respiration and heart rate. May cause frostbite. Avoid breathing gas. Self-contained breathing apparatus may be required by rescue workers
_Potential Health Effects Information_
Inhalation:Carbon dioxide is an asphyxiant. Concentration of 10% or more can produce unconsciousness or death. Lower concentrations may cause headache, sweating, rapid breathing, increased heartbeat, shortness of breath, dizziness, mental depression, visual disturbances, and shaking.
Eye:Contact with liquid or cold vapor can cause freezing of tissue.
Skin:Contact with liquid or cold vapor can cause frostbite.
Chronic Effects:Not Established
Medical Conditions Aggravated By OverexposureNone.
Carcinogenicity:Carbon dioxide is not listed by NTP, OSHA or IARC.
_First Aid Measures_
Inhalation:Persons suffering from lack of oxygen should be removed to fresh air. If victim is not breathing, administer artificial respiration. If breathing is difficult, administer oxygen. Obtain prompt medical attention.
Eye:Contact with liquid or cold vapor can cause freezing of tissue. Gently flush eyes with lukewarm water. Obtain medical attention immediately.
Skin:Contact with liquid or cold vapor can cause frostbite. Immediately warm affected area with lukewarm water not to exceed 105°F (40°C).
Notes To Physician:There is no specific antidote. Treatment of overexposure should be directed at the control of symptoms and the clinical condition.
_Fire Fighting Measures_
Flash Point:Not applicable; Gas.
Auto ignition:Non Flammable
Flammable Limits - Lower: None
Flammable Limits - Upper:None
Extinguishing Media:Carbon dioxide is nonflammable and does not support combustion. Carbon dioxide is an extinguishing agent for class B and C fires. Use extinguishing media appropriate for the surrounding fire.
Fire Fighting Instructions:Evacuate personnel from danger area. Carbon dioxide is nonflammable. If possible, without risk, remove carbon dioxide cylinders from fire area or cool with water. Self-contained breathing apparatus may be required for rescue workers.
_Handling and Storage_
Storage:Store and use with adequate ventilation. Cylinders should be stored upright with valve protection cap in place and firmly secured to prevent falling or being knocked over. Protect cylinders from physical damage; do not drag, roll, slide or drop. Do not allow storage area temperature to exceed 125°F (52°C). Full and empty cylinders should be segregated. Use a first-in, first-out inventory system to prevent full containers from being stored for long periods of time
Handling:Use a suitable hand truck for cylinder movement. Never attempt to lift a cylinder by its valve protection cap. Keep cylinders and their valves free from oil and
grease. Open valve slowly. If user experiences difficulty operating cylinder valve, discontinue use and contact supplier. Never insert an object (e.g., wrench,
screwdriver, pry bar, etc.) into valve cap openings. Doing so may damage valve, causing a leak to occur. Never strike an arc on a compressed gas cylinder or make
a cylinder a part of an electrical circuit. Use an adjustable strap wrench to remove over-tight or rusted caps. For additional precautions in using oxygen see Section 16
- Other Information.
_Exposure Control - Personal Protection_
_Engineering Controls:_
Ventilation:Provide adequate natural or explosion-proof mechanical ventilation to ensure acetylene does not accumulate and reach its lower explosive limit of 2.5%
_Personal Protective Equipment (PPE):_
_Skin Protection:_
Clothing:Cotton clothing is recommended for use to prevent static buildup.
Glasses: Safety glasses are recommended when handling cylinders.
Shoes:Safety shoes are recommended when handling cylinders.
Gloves:Work gloves are recommended when handling cylinders.
Respiratory Protection:Before entering area you must check for flammable and oxygen deficient atmospheres.
Respirator:None required in general use.
Wear a NIOSH/MSHA-approved (or equivalent) full-face piece airline respirator in the positive pressure mode in oxygen deficient atmospheres (air purifying respirators will not function).
