Lack of Oxygen
One of the most common forms of asphyxiation is caused by a lack of oxygen in the environment. This can occur due to several different factors, such as when an enclosed space is poorly ventilated, or when an individual is trapped in an area with a low oxygen level. Examples of this type of hazard include being trapped in an airtight room or container, being stuck in a collapsed structure, or being submerged in water for an extended period of time.
Carbon Dioxide Accumulation
Another form of asphyxiation is caused by the accumulation of carbon dioxide in the environment. This can occur when air is trapped in an enclosed space, such as a basement or attic, and the oxygen is slowly used up, leading to a build-up of carbon dioxide. This type of hazard can also occur when an individual is stuck in an area that is not well ventilated, leading to a build-up of carbon dioxide in the air.
Chemical Fumes
In some cases, asphyxiation can be caused by the inhalation of chemical fumes. These fumes can be released from certain substances, such as paints, solvents, and other chemicals. Examples of this type of hazard include being exposed to paint fumes, being in a poorly ventilated area that contains solvents, or being in an area where chemicals are being used.
Smoke Inhalation
Smoke inhalation is another form of asphyxiation that can be caused by being trapped in an area that is filled with smoke. This can occur in a burning building or during a forest fire. Examples of this type of hazard include being trapped in a burning building or being stuck in an area where a forest fire is burning.
