EXTINGUISHING MEDIA:
Use any standard agent – choose the one most appropriate for type of surrounding fire (material itself is not flammable)
UNUSUAL FIRE AND EXPLOSION HAZARDS:
Carbon Dioxide cannot catch fire. Heat of fire can build pressure in cylinder and cause it to rupture. No part of the container
should be exposed to a temperature higher than 125˚F. Liquid carbon dioxide containers are equipped with pressure relief
devices.
SPECIAL FIRE FIGHTING PRECAUTIONS/INSTRUCTIONS:
WARNING: High-pressure liquid and gas. Firefighters should wear appropriate gear for surrounding fire. Evacuate all
personnel from impacted area. Immediately spray containers with water from maximum distance until cool, taking care not to
spray water on to vents on top of container. Do not discharge sprays in to liquid carbon dioxide, which will freeze water
rapidly. When containers have cooled, move them away from fire area if it can be done without risk. Self-contained breathing
apparatus may be required by rescue workers. On-site fire brigades must comply with OSHA 29 CFR 1910.156 and
applicable standards under 29 CFR 1910 Subpart L—Fire Protection.
6. ACCIDENTAL RELEASE MEASURES
WARNING! Cold liquid and gas under pressure
Carbon dioxide is an asphyxiant. Lack of oxygen can kill. Evacuate all personnel from release area. Use self contained
breathing apparatus and protective clothing where needed. Liquid carbon dioxide will not "spill". Flakes of carbon dioxide
will form at pressures below 67 psig (461.95 kPa) and fall as snow. Shut off leak if you can do so without risk. Ventilate area
or move container to a well-ventilated area. Test for sufficient oxygen, especially in confined spaces, before allowing entry.
Prevent waste from contaminating the surrounding environment. Keep personnel away. Discard any product, residue,
disposable container, or liner in an environmentally acceptable manner, in full compliance with federal, state, and local
regulations
7. HANDLING AND STORAGE
NORMAL HANDLING:
Never allow any unprotected part of your body to touch un-insulated pipes or vessels containing refrigerated liquid. Flesh
will stick to the extremely cold metal and tears when you try to pull it free. Use suitable hand truck to move containers.
Containers must be handles and stored in an upright position. Do not drop or tip containers, or roll them on their sides. If
valve is hard to open discontinue use and contact your supplier.
STORAGE RECOMMENDATIONS:
Gas can cause rapid suffocation due to oxygen deficiency. Store and use with adequate ventilation. Do not store in a confined
space. Carbon dioxide is heavier than air. It tends to accumulate near the floor of an enclosed space, displacing air and
pushing it upward. This creates an oxygen deficient atmosphere near the floor. Ventilate the space before entry. Verify
sufficient oxygen concentration. Close container valve after each use; keep closed even when empty. Use adequate pressure
relief devices in systems and piping to prevent pressure build up.
INCOMPATIBLITIES:
Alkali metals, alkaline earth metals, metal acetylides, chromium, titanium above 1022˚F (550˚C), uranium above ˚F (750˚C),
magnesium above 1427˚F (775˚C).
