Metallurgy Carbon Dioxide Flammable Colorless Gas Industrial Grade
Electronic Gases Carbon Monoxide is a colorless, odorless,
flammable toxic gas. It is a chemical asphyxiant and acts toxically
by combining with the hemoglobin of the red blood cells to form the
stable compound carbon monoxide-hemoglobin. If inhaled,
concentrations of 0.4 percent in air can prove fatal in less than
one (1) hour, while inhalation of high concentrations can cause
sudden collapse with little or no warning. Carbon Monoxide is
stable with respect to decomposition.
Carbon Monoxide is used in metallurgy, manufacturing acids,
chemical industry, lasers and laboratory R & D. Material Safety
Data Sheets (MSDS) are available for Carbon Monoxide and should be
used as guidelines in regard to first aid, methods of storage,
handling and general use of Carbon Monoxide.
Contact with the liquid can cause severe frostbite. Less dense than
air. Easily ignited and a flame can flash back to the source of a
leak very easily. Burns with a violet flame. Under prolonged
exposure to fire or intense heat the containers may rupture
violently and rocket. CARBON MONOXIDE is used in organic synthesis,
metallurgy, and a fuel.
Contact of very cold liquefied gas with water may result in
vigorous or violent boiling and extremely rapid vaporization. If
the water is hot, a liquid "superheat" explosion may occur.
Pressures may build to dangerous levels if the liquid contacts
water in a closed container [Handling Chemicals Safely 1980].
Reacts explosively with bromine trifluoride at high temperatures or
concentrations [Mellor 2, Supp. 1:166 1956]. The same is true for
various oxidizers such as: chlorine dioxide, oxygen (liquid),
peroxodisulfuryl difluoride. Reacts with lithium to give lithium
carbonyl, which detonates violently with water, igniting the
gaseous products [Mellor 2, Supp 2:84 1961]. Potassium and sodium
metals behave similarly. Cesium oxide, iron(III) oxide, and silver
oxide all react, in the presence of moisture, at ambient
temperatures with carbon monoxide causing ignition, [Mellor, 1941,
vol. 2, 487].
Toxic; Extremely Hazardous. Inhalation extremely dangerous; may be
fatal. Contact with gas or liquefied gas may cause burns, severe
injury and/or frostbite. Odorless, will not be detected by sense of
Extremely flammable. May be ignited by heat, sparks or flames.
Flame may be invisible. Containers may explode when heated. Vapor
explosion and poison hazard indoors, outdoors or in sewers. Vapors
from liquefied gas are initially heavier than air and spread along
ground. Vapors may travel to source of ignition and flash back.
Runoff may create fire or explosion hazard.
