Health Hazards Data
=======================================================
Route Of Entry Inds - Inhalation: YES
Skin: YES
Ingestion: NO
Carcinogenicity Inds - NTP: NO
IARC: NO
OSHA: NO
Effects of Exposure: EMERGENCY OVERVIEW: CAUTION! HIGH PRESSURE GAS. CAN CAUSE
RAPID SUFFOCATION. MAY CAUSE DIZZINESS AND DROWSINESS. SELF-CONTAINED
BREATHING APPARATUS MAY BE REQUIRED BY RESCUE WORKERS. EFFECTS OF A SING LE
(ACUTE) OVEREXPOSURE: INHALATION- ASPHYXIANT. EFFECTS ARE DUE TO LACK OF
OXYGEN. THE CARBON DIOXIDE COMPONENT IS ALSO PHYSIOLOGICALLY ACTIVE,
AFFECTING CIRCULATION AND BREATHING. MODERATE CONCENTRA TIONS MAY CAUSE
HEADACHE, DROWSINESS, DIZZINESS, EXCITATION, EXCESS SALIVATION, VOMITING, AND
UNCONSCIOUSNESS. LACK OF OXYGEN CAN KILL. SKIN CONTACT - NO HARM EXPECTED.
SWALLOWING - THIS PRODUCT IS A (SIGNS AND SYMPTOMS OF OVEREXPOSURE)
Explanation Of Carcinogenicity: NONE OF THE COMPONENTS OF THIS MIXTURE IS
LISTED BY NTP, OSHA, OR IARC.
Signs And Symptions Of Overexposure: HEALTH HAZARDS ACUTE AND CHRONIC (CONT): A
GAS AT TEMPERATURE AND PRESSURE. EYE CONTACT - NO HARM EXPECTED. EFFECTS OF
REPEATED (CHRONIC) OVEREXPOSURE: NO HARM EXPECTED. OTHER EFFECTS OF
OVEREXPOSUR E: DAMAGE TO RETINAL GANGLION CELLS MAY OCCUR. SIGNIFICANT
LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH HAZARD EVALUATION: A
SINGLE STUDY HAS SHOWN AN INCREASE IN HEART DEFECTS IN RATS EXPO SED TO 6%
CARBON DIOXIDE IN AIR FOR 24 HOURS AT DIFFERENT TIMES DURING GESTATION. THERE
IS NO EVIDENCE THAT CARBON DIOXIDE IS TERATOGENIC IN HUMANS.
Medical Cond Aggravated By Exposure: THE TOXICOLOGY AND THE PHYSICAL AND
CHEMICAL PROPERTIES OF THE MIXTURE COMPONENTS SUGGEST THAT OVEREXPOSURE IS
UNLIKELY TO AGGRAVATE EXISTING MEDICAL CONDITIONS.
First Aid: INHALATION: REMOVE TO FRESH AIR. IF NOT BREATHING, GIVE ARTIFICIAL
RESPIRATION . IF BREATHING IS DIFFICULT, QUALIFIED PERSONNEL MAY GIVE OXYGEN.
CALL A PHYSICIAN. SKIN CONTACT: NO EMERGENCY CARE ANTI CIPATED. SWALLOWING:
THIS PRODUCT IS A GAS AT NORMAL TEMPERATURE AND PRESSURE. EYE CONTACT: FLUSH
EYES WITH WARM WATER. HOLD THE EYELIDS OPEN AND AWAY FROM THE EYEBALLS TO
ENSURE THAT ALL SURFACES A RE FLUSHED THOROUGHLY. NOTES TO PHYSICIAN: THERE
IS NO SPECIFIC ANTIDOTE. THIS PRODUCT IS INERT. TREATMENT OF OVER-EXPOSURE
SHOULD BE DIRECTED AT THE CONTROL OF SYMPTOMS AND THE CLINICAL CONDITION OF
PATIENT.

VENTILATE AREA OR MOVE CYLINDER TO A WELL-VENTILATED AREA. TEST FOR
SUFFICIENT OXYGEN, ESPECIALLY IN CONFINED SPACES, BEFORE ALLOWING REENTRY.
Waste Disposal Methods: PREVENT WASTE FROM CONTAMINATING THE SURROUNDING
ENVIRONMENT. KEEP PERSONNEL AWAY. DISCARD ANY PRODUCT, RESIDUE, DISPOSABLE
CONTAINER OR LINER IN AN ENVIRON ACCEPTABLE MANNER, IN FULL COMPLIANCE WITH
FEDERAL, STATE, AND LOCAL REGULATIONS. IF NECESSARY, CALL YOUR LOCAL SUPPLIER
FOR ASSISTANCE.
