Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:ACUTE: CARBON MONOXIDE IS HIGHLY TOXIC
BY THE REDUCTION OF THE BLOOD'S OXYGEN CARRYING CAPACITY RESULTING
IN OXYGEN STARVATION OF BODY CELLS. MIXTURE CAN ACT AS A SIMPLE
ASPHYXIANT BY DISPLACING AIR N ECESSARY FOR LIFE. SYMPTOMS INCLUDE
RAPID RESPIRATION, MUSCULAR INCOORDINATION, FATIGUE, DIZZINESS,
NAUSEA, VOMITING, UNCONSCIOUSNESS AND DEATH. CHRONIC:
CARDIOVASCULAR PROBLEMS.
Explanation of Carcinogenicity:NONE
Effects of Overexposure:SYMPTOMS INCLUDE RAPID RESPIRATION, MUSCULAR
INCOORDINATION, FATIGUE, DIZZINESS, NAUSEA, VOMITING,
UNCONSCIOUSNESS AND DEATH
Medical Cond Aggravated by Exposure:NONE KNOWN

First Aid:INHALATION: IMMEDIATELY REMOVE VICTIM TO FRESH AIR. IF
BREATHING IS DIFFICULT, GIVE OXYGEN. IF BREATHING HAS STOPPED, GIVE
ARTIFICIAL RESPIRATION. EYE: NONE. SKIN: NONE. INGESTION: NONE. IN
EVENT OF E XPOSURE, CONSULT A PHYSICIAN.

WATER SPRAY. IF POSSIBLE, STOP THE PRODUCT FLOW.
Unusual Fire/Explosion Hazard:CYLINDER RUPTURE MAY OCCUR UNDER FIRE
CONDITIONS.

Spill Release Procedures:EVACUATE AND VENTILATE AREA. REMOVE LEAKING
CYLINDER TO EXHAUST HOOD OR SAFE OUTDOOR AREA. SHUT OFF SOURCE IF
POSSIBLE AND REMOVE SOURCE OF HEAT.
Neutralizing Agent:NOT RELEVANT

Handling and Storage Precautions:SECURE CYLINDER WHEN USING TO PROTECT
FROM FALLING. USE SUITABLE HAND TRUCK TO MOVE CYLINDERS. NO PART OF
CYLINDER SHOULD BE EXPOSED TO TEMPERATURES ABOVE 52 DEG C. STORE IN
WELL VENTILATED AREAS. KEE P VALVE PROTECTION CAP ON CYLINDERS WHEN
NOT IN USE.
Other Precautions:PROTECT CONTAINERS FROM PHYSICAL DAMAGE. DO NOT
DEFACE CYLINDERS OR LABELS. CYLINDERS SHOULD BE REFILLED BY
QUALIFIED PRODUCERS OF COMPRESSED GAS. SHIPMENT OF A COMPRESSED GAS
CYLINDER WHICH HAS NOT B EEN FILLED BY THE OWNER OR WITH HIS
WRITTEN CONSENT IS A VIOLATION OF FEDERAL LAW (49 CFR)

Respiratory Protection:USE A SELF CONTAINED BREATHING APPARATUS IN CASE
OF EMERGENCY OR NON-ROUTINE USE.
Ventilation:PROVIDE ADEQUATE GENERAL AND LOCAL EXHAUST VENTILATION TO
MAINTAIN CONCENTRATIONS BELOW EXPOSURE LIMITS AND TO AVOID
ASPHYXIATION
Protective Gloves:NONE
