Which of the following conditions are examples of a hazardous atmosphere?

Atmospheric Hazards. Atmospheric hazards include things such as oxygen deficiencies, dusts, chemical vapors, welding fumes, fogs, and mists that can interfere with the bodies ability to transport and utilize oxygen, or that have negative toxicological effects on the human body.

What is considered a hazardous atmosphere?

Hazardous atmospheres include oxygen deficient environments, flammable/combustible/explosive environments and toxic environments. An oxygen-deficient atmosphere means there is not enough oxygen in the space. Normal air has 20.8% oxygen. Levels below 19.5% are considered oxygen-deficient.

What are the three main atmospheric hazards?

Three main atmospheric hazards may be encountered in confined/enclosed spaces. These hazards consist of low or high oxygen levels, toxic gases or vapors, and flam- mable atmospheres. To ensure that these spaces are safe to enter, test the atmosphere prior to entry.

What are hazardous atmospheres caused by?

The major causes of a hazardous atmosphere are flammable contents, an oxygen-poor atmosphere and toxins. A waste-, chemical- or toxic-releasing product can give off poisonous gases that contaminate the environment and cause personnel to inhale toxic compounds.

What are the two basic categories of hazardous atmosphere?

Atmospheric hazards that may exist within the confined space can be divided into three major categories: oxygen deficiency or enrichment, flammable materials, and toxic materials. All could pose a life-threatening situation.

Understanding Global Atmospheric Circulation - GCSE Geography

Which of the following is NOT atmospheric hazard?

The answer is(b) Drought.

What is a hazardous atmosphere OSHA?

Note to paragraph (4) of the definition of "Hazardous atmosphere". An atmospheric concentration of any substance that is not capable of causing death, incapacitation, impairment of ability to self-rescue, injury, or acute illness due to its health effects is not covered by this definition.

Which of the following is an example of a hazardous atmosphere in a confined space?

The following are examples of hazardous atmospheres within a confined space: Flammable or explosive gas, vapor, or mist in a concentration greater than 10 percent of its lower flammable limit (LFL) or lower explosive limit (LEL).

What are four different atmospheric conditions that may be encountered in a confined space?

What are the types of hazards?

Is example of atmospheric disaster?

Atmospheric hazard: tropical cyclone, tornado, hail, snow, lightning and thunderstorm, long-term climatic change, and short-term climatic change.

What are 3 different types of hazards in confined spaces?

Which of the following is the most common type of hazard in a confined space?

Some of the most common hazards of working in a confined space are: No Ventilation: Without proper ventilation in a confined space, gases will begin to build up quickly. Even otherwise harmless gases can become deadly in a small space.

What are the potential hazards of a confined spaces?

If a flammable atmosphere inside a confined space ignites, an explosion may occur, resulting in the expulsion of hot gases and the disintegration of the structure. Liquids or solids can flow into the confined space causing drowning, suffocation, burns and other injuries.

How many types of hazards are there in confined space?

According to Safe Work Australia's “Confined Spaces: Code of Practice”, there are 16 major hazards associated with a confined space.

How does OSHA define an oxygen deficient atmosphere?

While normal atmosphere contains between 20.8 and 21 percent oxygen, OSHA defines as oxygen deficient any atmosphere that contains less than 19.5 percent oxygen, and as oxygen enriched, any atmosphere that contains more than 22 percent.

What is a flammable atmosphere?

In order for an atmosphere to become flammable, it must have the proper mixture of fuel and oxygen. If the concentration of a specific gas is below the lower explosive limit (LEL) it is too lean to burn. If the concentration is above the upper explosive limit (UEL) it is too rich to burn.

What is the most common hazard associated with confined spaces quizlet?

As stated earlier, one of the greatest hazards in confined spaces is the atmosphere. It can contain flammable gases, toxic gases, or an atmosphere depleted of or enriched in oxygen.

Which four of the following are examples of non atmospheric hazards?

These hazards include such items as scaffolding, surface residues, and structural hazards. Scaffolding in confined spaces has contributed to many accidents caused by workers, materials falling, improper use of guard rails, and lack of maintenance to insure worker safety.

Is an earthquake a atmospheric hazard?

Types of natural hazards

These events include earthquakes, volcanic eruptions, and landslides. Meteorological hazards occur as a result of processes in the atmosphere. Meteorological hazards include extreme temperatures, hurricanes, tornadoes, droughts, and severe storms.

What are the 5 types of hazards?

What are the 6 types of hazards?

What are 3 examples of confined space?

Confined spaces include, but are not limited to, tanks, vessels, silos, storage bins, hoppers, vaults, pits, manholes, tunnels, equipment housings, ductwork, pipelines, etc.

What is a confined space give 2 examples?

A confined space, despite its name, is not necessarily small. Examples of confined spaces include silos, vats, hoppers, utility vaults, tanks, water supply towers, sewers, pipes, access shafts, truck or rail tank cars, aircraft wings, boilers, manholes, pump stations, digesters, manure pits and storage bins.
