3. HAZARD IDENTIFICATION <br /> EMERGENCY OVERVIEW. This product is a colorless, odorless gas. Releases of this product may produce <br /> oxygen-deficient atmospheres (especially in confined spaces or other poorly-ventilated environments); <br /> individuals in such atmospheres may be asphyxiated. Isobutylene, a component of this gas mixture, may <br /> cause drowsiness and other central nervous system effects in high concentrations; however, due to its low <br /> concentration in this as mixture, this is unlikely to occur. <br /> SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF <br /> EXPOSURE: The most significant route of over-exposure for this HAZARDOUS MATERIAL INFORMATION <br /> product is by inhalation. SYSTEM <br /> INHALATION: Due to the small size of an individual cylinder of HEALTH <br /> this product, no unusual health effects from over-exposure to the (BLUE) <br /> product are anticipated under routine circumstances of use. The <br /> chief health hazard associated with this gas mixture is when this <br /> product contains less than 19.5% Oxygen and is released in a <br /> small, poorly-ventilated area (i.e. an enclosed or confined FLAMMABILITY (REQ 0 <br /> space). Under this circumstance, an oxygen-deficient <br /> environment may occur. Individuals breathing such an <br /> atmosphere may experience symptoms which include REACTIVITY �^'� o <br /> headaches, ringing in ears, dizziness, drowsiness, <br /> unconsciousness, nausea, vomiting, and depression of all the <br /> senses. Under some circumstances of over-exposure, death <br /> may occur. The effects associated with various levels of oxygen PROTECTIVE EQUIPMENT )3 <br /> are as follows: <br /> CONCENTRATION OF OXYGEN OBSERVED EFFECT EYES ATOW FMOS BWY <br /> 12-16% Oxygen: Breathing and pulse rate <br /> increase, muscular coor- See Section 8 <br /> dination slightly disturbed. <br /> 10-14% Oxygen: Emotional upset, abnormal <br /> fatigue, disturbed respiration. For routine industrial applications <br /> 6-10% Oxygen: Nausea, vomiting, collapse, or <br /> loss of consciousness. <br /> Below 6%: Convulsive movements, possible respiratory collapse, and death. <br /> HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Over-exposure to this gas <br /> mixture may cause the following health effects: <br /> ACUTE: Due to the small size of the individual cylinder of this product, no unusual health effects from exposure <br /> to the product are anticipated under routine circumstances of use. The most significant hazard associated with <br /> this gas mixture when it contains less than 19.5% oxygen is the potential for exposure to oxygen-deficient <br /> atmospheres. Symptoms of oxygen deficiency include respiratory difficulty, ringing in ears, headaches, shortness <br /> of breath, wheezing, headache, dizziness, indigestion, nausea, unconsciousness, and death. The skin of a victim <br /> of over-exposure may have a blue color. Additionally, Isobutylene, a component of this gas mixture, may cause <br /> drowsiness or central nervous system effects in high concentrations; however, due to its low concentration in this <br /> gas mixture, this is unlikely to occur. <br /> CHRONIC: There are currently no known adverse health effects associated with chronic exposure to this gas <br /> mixture. <br /> TARGET ORGANS: Respiratory system. <br /> 4. FIRST AID MEASURES <br /> RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THIS <br /> PRODUCT WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self- <br /> Contained Breathing Apparatus must be worn. <br /> No unusual health effects are anticipated after exposure to this product, due to the small cylinder size. If any <br /> adverse symptom develops after over-exposure to this product, remove victim(s) to fresh air as quickly as <br /> possible. Only trained personnel should administer supplemental oxygen and/or cardio-pulmonary resuscitation <br /> if necessary. <br /> NON-FLAMMABLE GAS MIXTURE MSDS-50054 EFFECTIVE DATE: November 12,2002 <br /> PAGE 20F7 <br />
