Mists are tiny liquid droplets usually created by spraying, mixing, or cleaning activities. Mists may be a combination of several hazardous ingredients. When hazardous dusts, fumes, or mists are breathed in, they become trapped in the respiratory system causing irritation. Short or long-term health problems may result, even death. Gases and Vapors - are invisible contaminants mixed in the air.
Gases are substances that become airborne at room temperature.
Gases are often produced by chemical processes and high-heat operations. They drift quickly and undetected from their source. Vapors are formed when liquids or solids evaporate, typically occurring with solvents, paints, or refining activities. Oxygen Deficiency - a lack of oxygen in the air. Oxygen deficiency can be caused by chemical reactions, fire, or displacement by other gases.
