What are the potential hazards associated with Oxygen (O2)?

Oxygen, vital for life, can also present hazards in certain situations. Awareness and proper precautions are necessary to mitigate these risks.

Key gas hazards associated with Oxygen (O2) include:

Increases the risk of fire and combustion. Accelerates ignition and spread of fires, especially in confined spaces.

Occurs in poorly ventilated areas or confined spaces. Can lead to asphyxiation, dizziness, loss of consciousness, and death.

Results from exposure to high concentrations of oxygen. Can cause respiratory issues, vision changes, convulsions, and neurological symptoms. Addressing these hazards requires monitoring oxygen levels, ensuring proper ventilation, and providing adequate training on safety protocols.
