Hazardous Atmospheres In Confined Spaces Employees in many industries enter a variety of confined spaces for inspections, testing, repair or cleaning. A confined space is any area that: (a) has limited openings for entry and exit; (b) may contain or produce toxic air contaminants; (c) has a high concentration of an inert gas; (d) is not intended for continuous occupancy; and (e) may have an oxygen-deficient atmosphere. All such spaces must be analyzed and tested before entry. Workers should also be trained to understand the hazards that may be found in these spaces. A few of the potentially hazardous gases are: Freon®...

CARBON MONOXIDE (CO) Carbon monoxide is a clear, odorless, heavier-than-air gas that is created by inefficient combustion emissions. The most common sources in industry are gasoline or diesel-powered pressure washers, air compressors, forklifts or other petroleum-fired machinery. The chemical makeup of CO is a carbon molecule linked to an oxygen molecule. The carbon molecule makes CO heavier than air and will not allow the lungs to absorb oxygen into the bloodstream. Without oxygen, you will slowly suffocate to death. What does this mean for workers? As the CO fills the space, it displaces oxygen and will affect workers as follows: Slight headache and...

Carbon Monoxide Safety What is Carbon Monoxide? Carbon Monoxide (CO) is a poisonous, colorless, tasteless, odorless gas. CO gas is generated as a waste product of the incomplete combustion of coal, wood, oil, and other petroleum based fuels (e.g. gasoline, propane, etc). CO gas, although odorless, usually occurs in a combination of combustion by-products that have distinctive odors. The primary source of CO gas is the internal combustion engine. CO gas is also generated in industrial operations such as auto repair, oil refining, steel and chemical manufacturing. Hazards of Carbon Monoxide Health Hazards: CO is a chemical asphyxiant which means that it reduces the blood’s...
