IV – Fire and Explosion Hazard Data
Fire Fighting Procedures
This material is non-combustible, used as an extinguishing agent for smothering
class B & C fires.
Fire and Explosion Hazards
Dry Ice should not be stored in air tight containers unless specifically
designed for that purpose; when confined in sealed containers, heat will cause
sublimation resulting in container rupture or an explosion.

V – Reactivity Data
Conditions to Avoid
Stable under normal conditions of
storage and use
(Materials to Avoid)
Carbon Dioxide will react with alkaline materials to form carbonates and
bicarbonates. CO2 is not effective for use on fires with
reactive metal (Sodium, Potassium, Magnesium, Aluminum, Titanium, and
Zirconium) or their hydrides.
Decomposition or Byproducts
decomposes to CO and O2 when heated above 1700˚C
Conditions to Avoid
Carbon Dioxide can cause violent
acrylaldehyde or ethyleneimine.
VI – Health Hazard Data
Hazards (Acute and Chronic)
CO2 can cause suffocation. 3% to 5% causes increased
respiration and headache but no known harmful effects from repeat
inhalation. Higher concentrations cause circulatory insufficiencies which
cause headache, nausea, vomiting and unconsciousness. Dry ice when
touched can cause severe frostbite which is a change in the color of the skin
to gray or white possibly followed by blistering.
and Symptoms of Exposure
nausea, vomiting, rapid breathing, perspiration, watery eyes, irritated nose
and throat, dizziness, drowsiness, unconsciousness, and a change in the color
of the skin to gray or white possibly followed by blistering in the case of
Conditions Generally Aggravated by Exposure
Persons in ill health where such illnesses would be aggravated by exposure to
Carbon Dioxide should not be allowed to work with or handle this product.
Persons with respiratory disease or heart disorders should avoid breathing
excessive Carbon Dioxide.
and First Aid Procedures
Immediately assist person overcome by CO2 to an uncontaminated area
to inhale fresh air. Unconscious persons after being moved to fresh air
should be given mouth-to-mouth resuscitation, administered oxygen, and medical
assistance sought immediately. Rescue personnel should be equipped with
self-contained breathing apparatus with full face mask. Frostbite – DO
NOT USE HOT WATER. Immerse affected area in lukewarm water and promptly
see a physician.
VII – Precautions for Safe Handling and Use
to Be Taken in Case Material is Released or Spilled
area of all personnel and provide adequate ventilation. Clean up should
be provided by personnel wearing self-contained breathing apparatus with full
face mask, insulated gloves, heavy protective clothing, and safety shoes.
waste to a well ventilated and isolated area and allow to sublime. Area
must be supervised until sublimation of all dry ice. DO NOT PUT DRY ICE
IN SEALED CONTAINERS UNLESS SPECIFICALLY DESIGNED FOR THAT PURPOSE.
to Be Taken in Handling and Storing
dry ice in well ventilated areas away from heat. Storage containers
specifically manufactured for the storage of dry ice should be used.
Local exhaust ventilation and/or general dilution ventilation should be used to
meet OSHA TWA 5,000PPM. Anyone handling dry ice should wear insulated
gloves, heavy clothing, face shields, and safety shoes.
VIII – Control Measures
Protection (Specify Type)
Local exhaust or general dilution ventilation to meet published exposure limits.
Yes, to well ventilated area
Exhaust fans where necessary
Safety glasses or full face shield
Protective Clothing or Equipment
shirts should be worn when handling dry ice as well as pants or
coveralls. Ties should be removed when viewing ice making equipment.
All dry ice storage containers should be free of all debris and trash before
storing dry ice in containers. Properly rated material handling equipment
should be used to transport containers between loading/unloading area and
