What is the potential hazard of using oxygen near sources of ignition?

Using oxygen near sources of ignition creates an increased combustion risk because oxygen is a highly reactive gas that supports and accelerates combustion. When oxygen levels are elevated, materials that typically may not ignite easily can catch fire more readily and burn more intensely. This is especially critical in medical settings where flammable substances might be present.

Oxygen enrichment can lower the ignition point of combustible materials, meaning they can ignite at lower temperatures than they would in normal air conditions. This is why strict protocols are in place regarding the use of oxygen and managing its proximity to ignition sources; it ensures safety by minimizing the risk of fires and explosions in environments where oxygen is utilized, like hospitals and clinics.
