FLAMMABLE GAS MIXTURE

SECTION 2: Hazards identification

EMERGENCY OVERVIEW: This is a colorless, flammable gas mixture, which may have a mild, gasoline-like odor. The main health hazard associated with this gas mixture is oxygen deprivation by displacing the oxygen in the atmosphere. The gas poses a serious fire hazard when accidentally released. The gas may spread long distances. Distant ignition and flashback are possible. Emergency responders must wear personal protective equipment appropriate for the situation to which they are responding. (Continued) INHALATION: The most significant hazard associated with this gas mixture is oxygen deprivation (asphyxiation) when this gas HAZARDOUS MATERIAL IDENTIFICATION SYSTEM mixture is present in high enough concentrations to significantly lower oxygen concentration. Individuals breathing such an atmosphere may experience symptoms which include HEALTH (BLUE) 1 headaches, ringing in ears, dizziness, drowsiness, unconsciousness, nausea, vomiting, and depression of all the senses. The effects associated with various levels of oxygen are as follows: FLAMMABILITY (RED) 4 CONCENTRATION SYMPTOMS OF EXPOSURE 12-16% Oxygen: Breathing and pulse rate increased, muscular coordination slightly disturbed. 10-14% Oxygen: Emotional upset, abnormal fatigue, REACTIVITY (YELLOW) 0 disturbed respiration. 6-10% Oxygen: Nausea and vomiting, collapse or loss of consciousness. PROTECTIVE EQUIPMENT B Below 6%: Convulsive movements, possible respiratory collapse, and death. It should be noted that before adverse health effects or EYES RESPIRATORY HANDS BODY suffocation could occur, the LEL of the main component, Propane may be reached, causing fire. Prolonged exposure to SEE SECTION 8 high concentration levels of this gas mixture (as may occur in a confined space) may also cause adverse effects on the central For routine applications. nervous system. Symptoms may include headache, dizziness, drowsiness, confusion and loss of consciousness. SKIN AND EYE CONTACT: Brief skin and eye contact is not See Section 16 for Definition of Ratings expected to cause adverse effect, unless contact is to an abrupt release of the gas mixture (see “Other Potential Health Effects” for further information). Prolonged contact with this gas mixture may result in irritation to the skin and eyes. Repeated skin exposure may cause dermatitis (dry, red, itchy skin). OTHER POTENTIAL HEALTH EFFECTS: The Propane component of this gas mixture is considered to be a weak cardiac sensitizer, based on animal testing. Contact with the rapidly expanding gases may cause frostbite. Symptoms of frostbite include change in skin color to white or grayish-yellow. The pain after contact can quickly subside.

Potential health effects

OR RISKS FROM EXPOSURE An Explanation in Lay Terms. Overexposure to this gas mixture may cause the health effects indicated below: ACUTE: This gas mixture can cause oxygen deprivation and presents a health hazard by displacing the oxygen in the atmosphere. High concentration inhalation exposure may cause adverse central nervous system effects. Contact with rapidly expanding gases (which are released under high pressure) may cause frostbite. Symptoms of frostbite include change in skin color to white or grayish-yellow. CHRONIC: Prolonged skin contact may result in mild irritation of the skin. Refer to Section 11 (Toxicological Information) of this MSDS for further information. TARGET ORGANS ACUTE Respiratory system, skin, eyes CHRONIC: Skin.
