CARBON MONOXIDE

CAS: 630-08-0

RTECS: FG3500000

OSHA PEL 55 MG/M3;50 PPM

ACGIH TLV: 29 MG/M3;25 PPM

LD50 LC50 Mixture:50 MOLAR PPM; STEL=400 MOLAR PPM (ACGIH)
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:ALL OF THE DISORDERS ARE DUE TO THE
MARKEDLY REDUCED CELULAR RESPIRATION AND MAY INCLUDE CENTRAL
NERVOUS SYSTEM IMPAIRMENT, CARDIOVASCULAR COLLAPSE, RENAL
INSUFFICIENCY COMA, ETC.
Effects of Overexposure:DEPENDING ON LEVELS AND DURATION OF EXPOSURE,
SYMPTOMS MAY INCLUDE HEADACHE, DIZZINESS, HEART PALPITATIONS,
WEAKNESS, CONFUSION AND NAUSEA TO CONVULSIONS, EVENTUAL
UNCONSCIOUSNESS AND DEATH. BECAUSE IT IS A COLORLESS AND ODORLESS
POISONOUS GAS, THERE IS NO WARNING OF ITS PRESENCE OTHER THAN THE
ABOVE SYMPTOMS. ANALYTICAL MONITORS, WITH ALARMS, SHOULD BE
EMPLOYED WHERE THE POSSIBILITY OF THE RELE ASED OF TOXIC QUANTITIES
EXISTS.

First Aid:PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
OVEREXPOSURE TO CARBON MONOXIDE. RESCUE PERSONNEL SHOULD BE
EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS AND BE COGNIZANT
OF EXTREME FIRE AND EXPLOSION HAZARD. INHALATION: CONSCIOUS
PERSONS SHOULD BE ASSISTED TO AN UNCONTAMINATED AREA AND BE TREATED
WITH SUPPLEMENTAL OXYGEN. QUICK REMOVAL FROM THE CONTAMINATED AREA
IS MOST IMPORTANT. UNC ONSCIOUS PERSONS SHOULD BE MOVED TO AN
UNCONTAMINATED AREA AND BE GIVEN ARTIFICIAL RESPIRATION AND OXYGEN
AT THE SAME TIME.

Flash Point:GAS
Autoignition Temp:=630.C, 1166.F
Lower Limits:12.5
Upper Limits:74.0
Extinguishing Media:WATER, DRY CHEMICAL, CARBON DIOXIDE
Fire Fighting Procedures:IF POSSIBLE, STOP THE FLOW OF CARBON MONOXIDE.
USE WATER SPRAY TO COOL SURROUNDING CONTAINERS.
Unusual Fire/Explosion Hazard:CARBON MONOXIDE HAS ALMOST THE SAME
DENSITY AS AIR. IT WILL NOT DIFFUSE BY RISING AS WITH SOME LIGHTER
FLAMMABLES SUCH AS HYDROGEN OR NATURAL GAS (METHANE).

Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA.
USE APPROPRIATE PROTECTIVE EQUIPMENT. IF LEAK IS IN USER'S
EQUIPMENT, BE CERTAIN TO PURGE PIPING WITH AN INERT GAS PRIOR TO
ATTEMPTING REPAIRS. IF LEAK IS IN CONTAINER OR CONTAINER VALVE,
CONTACT THE CLOSEST LIQUID AIR CORPORATION LOCATION.

Handling and Storage Precautions:USE ONLY IN WELL-VENTILATED AREAS.
VALVE PROTECTION CAPS MUST REMAIN IN PLACE UNLESS CONTAINER IS
SECURED WITH VALVE OUTLET PIPED TO USE POINT. DO NOT DRAG, SLIDE OR
ROLL CYLINDERS. USE A SUITABLE H AND TRUCK FOR CYLINDER MOVEMENT.
USE A PRESSURE REDUCING REGULATOR(SEE OTHER PRECAUTIONS)
Other Precautions:WHEN CONNECTING CYLINDER TO LOWER PRESSURE (<2,000
PSIG) PIPING OR SYSTEMS. DO NOT HEAT CYLINDER BY ANY MEANS TO
INCREASE THE DISCHARGE RATE OF PRODUCT FROM THE CYLINDER. USE A
CHECK VALVE OR TRAP IN THE DISCHARGE LINE TO PREVENT HAZARDOUS
BACKFLOW INTO THE CYLINDER.

Respiratory Protection:POSITIVE PRESSURE AIR LINE WITH MASK OR
SELF-CONTAINED BREATHING APPARATUS SHOULD BE AVAILABLE FOR
EMERGENCY USE.
Ventilation:HOOD WITH FORCED VENTILATION- LOCAL EXHAUST-TO PREVENT
ACCUMULATION ABOVE THE TWA. MECHANICAL-IN ACCORDANCE WITH
ELECTRICAL CODES.
Protective Gloves:PLASTIC OR RUBBER
Eye Protection:SAFETY GOGGLES OR GLASSES
Other Protective Equipment:SAFETY SHOES, SAFETY SHOWER

Waste Disposal Methods:DO NOT ATTEMPT TO DISPOSE OF RESIDUAL OR UNUSED
QUANTITIES. RETURN IN THE SHIPPING CONTAINER PROPERLY LABELED,
WITH ANY VALVE OUTLET PLUGS OR CAPS SECURED AND VALVE PROTECTION
CAP IN PLACE TO LIQUID AIR CORPPORATION FOR PROPER DISPOSAL. FOR
EMERGENCY DISPOSAL, CONTACT THE CLOSEST LIQUID AIR CORPOR ATION
LOCATION.

Toxicological Information:THE OXYGEN TRANSPORT FUNCTION OF THE
HEMOGLOBIN OF THE BLOOD IS REDUCED SINCE ITS NORMAL REACTION WITH
INHALED CARBON MONOXIDE TO FORM CARBOXY HEMOGLOBIN INSTEAD OF ITS
NORMAL REACTION WITH HTE OXYGE N IN THE LUNGS TO FORM
OXYHEMOGLOBIN. THE AFFINITY OF HEMOGLOBIN FOR CARBON MONOXIDE IS
200-300 TIMES GREATER THAN ITS AFFINITY FOR OXYGEN.
