80 CARBON MONOXIDE

CARBON MONOXIDE
Chemical Designations - Synonyms: Monoxide; Chemical Formula: CO.
Observable Characteristics - Physical State (as normally shipped): Compressed gas or liquefied gas;
Color: Colorless; Odor: None.
Physical and Chemical Properties - Physical State at 15 rand I atm. : Gas; Molecular Weight: 28.0;
Boiling Point at 1 atm.: -312.7, -191.5, 81.7; Freezing Point: -326, -199,74; Critical Temperature:
-220, -140, 133; Critical Pressure: 507.5, 34.51, 3.502; SpeciJic Gravity: 0.791 at -191.5"C (liquid);
Vapor (Gas) Density: 0.97; Ratio of SpeciJic Heats of Vapor (Gas): 1.3962; Latent Heat of
Vaporization: 92.8,51.6,2.16; Heat of Combustion: -4,343, -2,412, -101; HeatofDecomposition: Not

Health Hazards Information - Recommemkd Personal Protective Equipment: Self-contained breathing
apparatus; safety glasses and safety shoes; Type D or Type N canister mask; Symptoms Following
Exposure: Inhalation causes headache, dizziness, weakness of limbs, confusion, nausea,
unconsciousness, and finally death. 0.04% conc., 2-3 hr. or 0.06% conc., 1 hr. - headache and
discomfort; with moderate exercise, 0.1-0.2% will produce throbbing in the head in about % hr., and
confusion of the mind, headache, and nausea in about 2 hrs. 0.20 - 0.25% usually produces
unconsciousness in about '/4 hr. Inhalation of a 0.4% conc. can prove fatal in less than 1 hr. Inhalation
of high concentrations can cause sudden, unexpected collapse. Contact of liquid with skin will cause
frostbite; General Treatment for Exposure: INHALATION: remove from exposure; give oxygen if
available; support respiration; call a doctor. SKIN: if burned by liquid, treat as frostbite; Toxicity by
Inhalation (Threshold Limit Value): 50 ppm; Short-Tern Exposure Limits: 400 ppm, 15 min.; Toxicity
by Ingestion: Not pertinent (gas with low boiling point); Late Toxicity: Toxicity from overexposure
persists for many days; Vapor (Gas) Irritant Characteristics: Data not available; Liquid or Solid Im*tant
Characteristics: Data not available; Odor Threshold Not pertinent.
Fire Hazards - Flash Point: Not pertinent; Flammable Limits in Air (96): 12 - 75; Fire Extinguishing
Agents: Allow fire to burn out; shut off the flow of gas and cool adjacent exposures with water.
Extinguish (only if wearing a SCBA) with dry chemicals or carbon dioxide; Fire Extinguishing Agents
Not To Be Used Not pertinent; Special Hazards of Combustion Products: Asphyxiation due to carbon
dioxide production is a major concern; Behavior in Fire: Flame has very little color. Containers may
explode in fires; Ignition Temperature (deg. F) : 1,128; Electrical Hazard No data; Burning Rate: Not
pertinent.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reactions; Stability During Transport: Stable; Neutralizing Agents forAcicts and caustics: Not pertinent;
Polymerization: Not pertinent; Inhibitor of Polynrirization: Not pertinent.

84.2, 46.8, 1.959; Heat 0fCombustion: Not pertinent; Heat of Decomposition: Not pertinent.
Health Hazards Information - Recommended Personal Protective Equipment: Organic vapor canister
with 111 face mask; protective clothiig; rubber gloves; Symptoms Following Exposure: Dizziness,
incoordination, anesthesia; may be accompanied by nausea and liver damage. Kidney damage also
occurs, often producing decrease or stopping of urinary output; General Treatment for Exposure: EYES
OR SKIN: flush with plenty of water; for eyes, get medical amtion. Remove contaminated clothing
and wash before reuse. INHALATION: immediately remove to fresh air, keep patient warm and quiet
and get medical attention promptly. Start artificial respiration if breathing stops. INGESTION induce
