<br />Potential Health Effects
<br />Inhalation
<br />Acute (Immediate)l A potential health hazard associated with this gas mixture is the inhalation of
<br />Hydrogen Sulfide, a component of this gas mixture. Such over-exposures may occur if
<br />this gas mixture is used in a confined space or other poorly-ventilated area. Over-
<br />exposures to Hydrogen Sulfide can cause dizziness, headache, nausea, respiratory
<br />arrest, coma, or unconsciousness. Continuous inhalation of low concentrations of
<br />Hydrogen Sulfide may cause olfactory fatigue, so that the odor is no longer an
<br />effective warning of the presence of this gas. Inhalation over-exposures to
<br />atmospheres containing more than the Threshold Limit Value of Carbon Monoxide (25
<br />ppm), another component of this gas mixture, can result in serious health
<br />consequences. Carbon Monoxide is classified as a chemical asphyxiant, producing a
<br />toxic action by combining with the hemoglobin of the blood and replacing the available
<br />oxygen. Through this replacement, the body is deprived of the required oxygen, and
<br />asphyxiation occurs. Since the affinity of Carbon Monoxide for hemoglobin is about
<br />200-300 times that of oxygen, only a small amount of Carbon Monoxide will cause a
<br />toxic reaction to occur. Carbon Monoxide exposures in excess of 50 ppm will produce
<br />symptoms of poisoning if breathed for a sufficiently long time. If this gas mixture is
<br />released in a small, poorly ventilated area (i.e. an enclosed or confined space),
<br />symptoms which may develop include the following: bright red lips and fingernails,
<br />headache progessing to heart palpitations, staggering, confusion, nausea, dizziness
<br />and unconsciousness with higher concentration exposures. For exposures greater
<br />than 2500 ppm there is potential for collapse and death before warning symptoms are
<br />experienced. If the gas mixture being used contains less than 19.5% Oxygen and is
<br />released in a small, poorly ventilated area (i.e. an enclosed or confined space), an
<br />oxygen-deficient environment may occur. Individuals breathing such an atmosphere
<br />may experience symptoms which include headaches, ringing in ears, dizziness,
<br />drowsiness, unconsciousness, nausea, vomiting, and depression of all the senses.
<br />Under some circumstances of over-exposure, death may occur. The following effects
<br />associated with decreased levels of oxygen: increase in breathing and pulse rate,
<br />emotional upset, abnormal fatigue, nausea, vomiting, collapse, loss of consciousness,
<br />convulsive movements, respiratory collapse and death.
<br />Chronic (Delayed)l Chronic exposure to oxygen-deficient atmospheres (below 18% oxygen in air) may
<br />affect the heart and nervous system.
<br />Skin
<br />Acute (Immediate)l Hydrogen Sulfide, a component of this gas mixture, may be irritating to the skin.
<br />Chronic (Delayed)l No data available
<br />Eye
<br />Acute (Immediate)l May cause mild irritation. Inflammation and irritation of the eyes can occur at very low
<br />airborne concentration of Hydrogen Sulfide (less than 10 ppm). Exposure over several
<br />hours may result in “gas eyes” or “sore eyes” with symptoms of scratchiness,
<br />irritation, tearing and burning. Above 50 ppm of Hydrogen Sulfide, there is an intense
<br />tearing, blurring of vision, and pain when looking at light. Over-exposed individuals may
<br />see rings around bright lights. Most symptoms disappear when exposure ceases.
<br />However, in serious cases, the eye can be permanently damaged.
<br />Chronic (Delayed)l No data available
<br />Ingestion
<br />Acute (Immediate)l Under normal conditions of use, no health effects are expected.
<br />Chronic (Delayed)l No data available
<br />Mutagenic Effects l The components of this gas mixture are not reported to cause mutagenic effects in
<br />humans.
