SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. See Notes.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
Inhalation causes headache, dizziness, weakness of limbs, confusion, nausea, unconsciousness, and finally death. 0.04% conc., 2-3 hr. or .06% conc., 1 hr.- headache and discomfort; with moderate exercise, 0.1-0.2% will produce throbbing in the head in about 1/2 hr., a tendency to stagger in about 1 1/2 hr., and confusion of the mind, headache, and nausea in about 2 hrs. 0.20-25% usually produces unconsciousness in about 1/2 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. (USCG, 1999)
Excerpt from ERG Guide 168 [Carbon Monoxide (Refrigerated Liquid)]: 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 smell. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
Treatment includes 100% oxygen and, in severe cases, hyperbaric oxygen. The half-life of carboxyhemoglobin is 6 hours at room air, 1.5 hours with 100% oxygen, and 23 minutes at three atmospheres of pressure.
SECTION 5: Firefighting measures
Suitable extinguishing media
Stop flow of gas before extinguishing fire. Use water spray to keep fire-exposed containers cool. Fire situation may require evacuation.
Specific hazards arising from the chemical
Special Hazards of Combustion Products: Asphyxiation due to carbon dioxide production may result. Behavior in Fire: Flame has very little color. Containers may explode in fire. (USCG, 1999)
Excerpt from ERG Guide 168 [Carbon Monoxide (Refrigerated Liquid)]: 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. (ERG, 2016)
Special protective actions for fire-fighters
Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with carbon dioxide, water spray, powder. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation. Remove all ignition sources.
Environmental precautions
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation. Remove all ignition sources.
Methods and materials for containment and cleaning up
1. Ventilate area of leak or release to disperse gas. 2. Stop flow of gas. If source of leak is a cylinder and the leak cannot be stopped in place, remove the leaking cylinder to a safe place in the open air and repair the leak or allow the cylinder to empty.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

SECTION 10: Stability and reactivity
Reactivity

Chemical stability
no data available
Possibility of hazardous reactions
Flammable gas.The gas mixes well with air, explosive mixtures are easily formed. The gas penetrates easily through walls and ceilings.Bromine trifluoride and carbon monoxide react explosively 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. The product of the reaction between lithium and carbon monoxide, lithium carbonyl, 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]. Contact of very cold liquefied gas with water may result in vigorous or violent boiling of the product and extremely rapid vaporization due to the large temperature differences involved. If the water is hot, there is the possibility that a liquid "superheat" explosion may occur. Pressures may build to dangerous levels if liquid gas contacts water in a closed container [Handling Chemicals Safely 1980].
